The problem of the excavator telescopic arm not working smoothly
Posted: Mar 12th, '25, 23:51
During the operation of the excavator, the telescopic arm undertakes the key extension and retraction tasks, and its smoothness directly affects the operating efficiency and accuracy of the excavator. Once the telescopic arm of the excavator is not smooth, it is like setting an obstacle to the normal operation of the equipment, which will not only reduce the working efficiency, but also cause additional damage to the equipment. In-depth exploration of the "https://www.dig-dog.com/collections/excavator" and mastering effective solutions are crucial to ensure the efficient and stable operation of the excavator.
In-depth Analysis of the Causes of the Unsmooth Telescopic Arm
Hydraulic System Failure
The hydraulic system is the core power source that drives the telescopic arm of the excavator, and its failure is one of the common reasons for the unsmooth telescopic arm. Hydraulic pump failure is more typical in the "Excavator Hydraulic Pump Affecting the Working Case of Telescopic Arm". When the internal parts of the hydraulic pump are severely worn, such as gear wear and plunger strain, the hydraulic pump output flow and pressure will be insufficient. When the telescopic arm is working, it cannot obtain sufficient hydraulic power support, and it will extend or retract slowly, jam or even fail to move. In addition, if the overflow valve in the hydraulic system fails, the system pressure cannot be adjusted normally, resulting in excessive or low pressure, which will also affect the normal operation of the telescopic arm. Excessive pressure may make the telescopic arm move too quickly and difficult to control; while too low pressure will make the telescopic arm lack power and move slowly.
Telescopic arm mechanical parts wear
Long-term high-intensity operation will cause serious wear of the mechanical parts of the telescopic arm. The slider, slide rail and other parts of the telescopic arm are prone to wear and deformation in frequent relative movements. In the "Analysis of the Slider Wear of the Excavator Telescopic Arm Leading to Smoothness", after the slider is worn, the matching gap between it and the slide rail increases, which will cause the telescopic arm to shake and jam during movement. Moreover, the connecting parts of the telescopic arm, such as the pin shaft and pin sleeve, are also prone to wear due to long-term exposure to large shear forces. When the gap between the pin shaft and the pin sleeve is too large, it will affect the connection stability between the sections of the telescopic arm, which will cause the telescopic arm to move unsmoothly, and in severe cases may even cause safety accidents.
Lubrication system problems
Good lubrication is the key to ensuring the normal operation of the mechanical parts of the telescopic arm. If the lubrication system fails, it will aggravate the wear of mechanical parts and cause the telescopic arm to operate unsmoothly. Insufficient grease is a common problem. In some construction sites with harsh working environments and high dust content, the grease is easily washed away or deteriorated, but the operator fails to replenish and replace it in time. In the "Excavator Telescopic Arm Failure Case", due to the long-term lack of sufficient grease, the friction between the slider and the slide rail of the telescopic arm increased, which not only made the telescopic arm difficult to move, but also generated abnormal noise and accelerated the wear of parts. In addition, the quality of grease is also crucial. If grease that does not meet the specifications is used, its lubrication performance cannot meet the working requirements of the telescopic arm, which will also cause the telescopic arm to operate unsmoothly.
Impurity contamination and foreign body interference
The operating environment of the excavator is complex, and impurities such as dust and sand can easily enter the internal structure of the telescopic arm. These impurities will accumulate between the slider and the slide rail, in the pipelines and valve bodies of the hydraulic system, and hinder the normal movement of the telescopic arm. In the "Analysis of Impurities Causing Failure of Excavator Telescopic Arm", after impurities enter the hydraulic system, they may block key parts such as hydraulic oil filters and throttle holes, affect the normal circulation of hydraulic oil, cause unstable pressure in the hydraulic system, and then affect the movement of the telescopic arm. In addition, foreign objects at the construction site, such as fallen stones and tools, may get stuck between the sections of the telescopic arm, causing the telescopic arm to be blocked when extending or retracting, and unable to work normally.
Methods for troubleshooting the problem of telescopic arm not working smoothly
Hydraulic system troubleshooting
When it is found that the telescopic arm of the excavator is not working smoothly, the hydraulic system should be thoroughly checked first. Use professional hydraulic testing equipment to test the output pressure and flow of the hydraulic pump, and compare the test data with the standard parameters of the equipment. If the pressure and flow are lower than the standard value, it is likely that the hydraulic pump has failed, and it is necessary to further disassemble and check the wear of the internal parts of the hydraulic pump. At the same time, check the working status of the overflow valve, and observe the movement changes of the telescopic arm by adjusting the pressure setting value of the overflow valve to determine whether the overflow valve is working properly. In addition, check whether there is leakage in the hydraulic system pipeline, whether the oil level and oil quality of the hydraulic oil are normal, and ensure that the hydraulic system can provide stable and sufficient power for the telescopic arm.
Mechanical parts inspection
Carefully inspect the mechanical parts of the telescopic arm. Observe whether the movement between the sections of the telescopic arm is smooth during the extension and retraction process, and whether there is shaking or jamming. Focus on checking the wear of the slider and the slide rail. The degree of wear can be judged by measuring the gap between the slider and the slide rail. If the gap exceeds the normal range, it is necessary to replace the slider or repair the slide rail in time. For the connection parts such as the pin shaft and the pin sleeve, check whether the connection is firm and whether there is any looseness. Use professional tools to measure the matching clearance between the pin shaft and the pin sleeve. If the clearance is too large, the worn pin shaft or pin sleeve should be replaced in time to ensure that the connection between the mechanical parts of the telescopic arm is tight and the movement is smooth.
Lubrication system inspection
When troubleshooting the lubrication system, first check whether there is enough grease at the grease filling point. This can be judged by opening the grease filling nozzle and observing the outflow of grease. If the grease is insufficient, it should be replenished in time with grease that meets the specifications. At the same time, check the quality of the grease and observe whether its color and texture are normal. If the grease changes color, becomes thinner or contains impurities, it means that the grease has deteriorated and the lubrication system needs to be thoroughly cleaned and replaced with new grease. In addition, it is also necessary to check whether the pipeline of the lubrication system is unobstructed, whether there is any blockage or leakage, and ensure that the grease can reach all parts that need lubrication smoothly.
Impurities and foreign matter inspection
Carefully check the external and internal structure of the telescopic arm to see if there are any foreign objects stuck between the sections of the telescopic arm. For some parts that are difficult to observe directly, tools such as flashlights can be used for auxiliary lighting. If foreign objects are found, they should be carefully removed to avoid secondary damage to the telescopic arm during the removal process. At the same time, check the filter of the hydraulic system to see if there are a lot of impurities accumulated on the filter. If the filter is seriously blocked, it is necessary to replace the filter in time and clean the hydraulic system to prevent impurities from continuing to damage the system and affect the normal operation of the telescopic arm.
Measures to solve the problem of unsmooth telescopic arm operation
Repair of hydraulic system faults
For hydraulic system faults, if the hydraulic pump is severely worn, it is necessary to disassemble the hydraulic pump and replace the worn parts, such as gears, plungers, etc. After replacing the parts, the hydraulic pump should be debugged to ensure that its output pressure and flow return to normal. For overflow valve failure, it can be repaired or replaced according to the specific situation. During repair, the overflow valve should be cleaned and adjusted so that it can regulate the system pressure normally. If the overflow valve is severely damaged and cannot be repaired, a new overflow valve should be replaced. After the repair is completed, the hydraulic system should be fully pressure tested and flow regulated to ensure that the hydraulic system can stably and reliably provide power support for the telescopic arm.
Repair and replacement of mechanical parts
For the wear problem of the mechanical parts of the telescopic arm, if the slider is lightly worn, the slider can be polished and repaired to make its surface smooth and restore normal cooperation with the slide rail. If the slider is severely worn, a new slider should be replaced in time. When replacing the slider, choose a product that is consistent with the specifications of the original equipment, ensure that it is installed correctly, and adjust the gap between the slider and the slide rail. For worn pins and pin sleeves, they should be replaced in time. When installing new pins and pin sleeves, apply an appropriate amount of grease to ensure flexible rotation of the connection parts. At the same time, conduct a comprehensive inspection of other mechanical parts of the telescopic arm, repair or replace problematic parts, and ensure the integrity and stability of the mechanical structure of the telescopic arm.
Lubrication system maintenance and improvement
Strengthen the maintenance of the lubrication system. Regularly add grease to each lubrication point of the telescopic arm to ensure that the grease filling amount is sufficient. Select grease with reliable quality and in line with the equipment use requirements, and reasonably adjust the grease filling cycle according to different operating environments and working conditions. At the same time, regularly check and clean the pipelines of the lubrication system to prevent pipeline blockage or leakage. Filters can be installed in the lubrication system to further improve the cleanliness of the grease and reduce the wear of impurities on mechanical parts. By improving the maintenance and improvement measures of the lubrication system, good lubrication guarantees are provided for the smooth operation of the telescopic arm.
Impurity and foreign matter cleaning and prevention
Timely clean up impurities and foreign matter inside and outside the telescopic arm to keep the equipment clean. Before the operation, clean up the construction site to avoid the accumulation of debris around the excavator and reduce the possibility of impurities and foreign objects entering the telescopic arm. When the equipment is parked, try to choose a clean and dry site, and cover the telescopic arm to prevent dust, mud and other impurities from invading. In addition, protective devices such as dust covers and sealing strips can be installed at key parts of the telescopic arm to effectively block the entry of impurities and foreign objects, and prevent the problem of telescopic arm not being smooth due to impurities and foreign objects from the source.

Use professional hydraulic testing equipment to test the output pressure and flow of the hydraulic pump, and compare the test data with the standard parameters of the equipment. If the pressure and flow are lower than the standard value, it is likely that the hydraulic pump has failed, and it is necessary to further disassemble and check the wear of the internal parts of the hydraulic pump. At the same time, check the working status of the overflow valve, and observe the movement changes of the telescopic arm by adjusting the pressure setting value of the overflow valve to determine whether the overflow valve is working properly. In addition, check whether there is leakage in the hydraulic system pipeline, whether the oil level and oil quality of the hydraulic oil are normal, and ensure that the hydraulic system can provide stable and sufficient power for the telescopic arm.
Mechanical parts inspection
Carefully inspect the mechanical parts of the telescopic arm. Observe whether the movement between the sections of the telescopic arm is smooth during the extension and retraction process, and whether there is shaking or jamming. Focus on checking the wear of the slider and the slide rail. The degree of wear can be judged by measuring the gap between the slider and the slide rail. If the gap exceeds the normal range, it is necessary to replace the slider or repair the slide rail in time. For the connection parts such as the pin shaft and the pin sleeve, check whether the connection is firm and whether there is any looseness. Use professional tools to measure the matching clearance between the pin shaft and the pin sleeve. If the clearance is too large, the worn pin shaft or pin sleeve should be replaced in time to ensure that the connection between the mechanical parts of the telescopic arm is tight and the movement is smooth.
Lubrication system inspection
When troubleshooting the lubrication system, first check whether there is enough grease at the grease filling point. This can be judged by opening the grease filling nozzle and observing the outflow of grease. If the grease is insufficient, it should be replenished in time with grease that meets the specifications. At the same time, check the quality of the grease and observe whether its color and texture are normal. If the grease changes color, becomes thinner or contains impurities, it means that the grease has deteriorated and the lubrication system needs to be thoroughly cleaned and replaced with new grease. In addition, it is also necessary to check whether the pipeline of the lubrication system is unobstructed, whether there is any blockage or leakage, and ensure that the grease can reach all parts that need lubrication smoothly.
Impurities and foreign matter inspection
Carefully check the external and internal structure of the telescopic arm to see if there are any foreign objects stuck between the sections of the telescopic arm. For some parts that are difficult to observe directly, tools such as flashlights can be used for auxiliary lighting. If foreign objects are found, they should be carefully removed to avoid secondary damage to the telescopic arm during the removal process. At the same time, check the filter of the hydraulic system to see if there are a lot of impurities accumulated on the filter. If the filter is seriously blocked, it is necessary to replace the filter in time and clean the hydraulic system to prevent impurities from continuing to damage the system and affect the normal operation of the telescopic arm.
Measures to solve the problem of unsmooth telescopic arm operation
Repair of hydraulic system faults
For hydraulic system faults, if the hydraulic pump is severely worn, it is necessary to disassemble the hydraulic pump and replace the worn parts, such as gears, plungers, etc. After replacing the parts, the hydraulic pump should be debugged to ensure that its output pressure and flow return to normal. For overflow valve failure, it can be repaired or replaced according to the specific situation. During repair, the overflow valve should be cleaned and adjusted so that it can regulate the system pressure normally. If the overflow valve is severely damaged and cannot be repaired, a new overflow valve should be replaced. After the repair is completed, the hydraulic system should be fully pressure tested and flow regulated to ensure that the hydraulic system can stably and reliably provide power support for the telescopic arm.
Repair and replacement of mechanical parts
For the wear problem of the mechanical parts of the telescopic arm, if the slider is lightly worn, the slider can be polished and repaired to make its surface smooth and restore normal cooperation with the slide rail. If the slider is severely worn, a new slider should be replaced in time. When replacing the slider, choose a product that is consistent with the specifications of the original equipment, ensure that it is installed correctly, and adjust the gap between the slider and the slide rail. For worn pins and pin sleeves, they should be replaced in time. When installing new pins and pin sleeves, apply an appropriate amount of grease to ensure flexible rotation of the connection parts. At the same time, conduct a comprehensive inspection of other mechanical parts of the telescopic arm, repair or replace problematic parts, and ensure the integrity and stability of the mechanical structure of the telescopic arm.
Lubrication system maintenance and improvement
Strengthen the maintenance of the lubrication system. Regularly add grease to each lubrication point of the telescopic arm to ensure that the grease filling amount is sufficient. Select grease with reliable quality and in line with the equipment use requirements, and reasonably adjust the grease filling cycle according to different operating environments and working conditions. At the same time, regularly check and clean the pipelines of the lubrication system to prevent pipeline blockage or leakage. Filters can be installed in the lubrication system to further improve the cleanliness of the grease and reduce the wear of impurities on mechanical parts. By improving the maintenance and improvement measures of the lubrication system, good lubrication guarantees are provided for the smooth operation of the telescopic arm.
Impurity and foreign matter cleaning and prevention
Timely clean up impurities and foreign matter inside and outside the telescopic arm to keep the equipment clean. Before the operation, clean up the construction site to avoid the accumulation of debris around the excavator and reduce the possibility of impurities and foreign objects entering the telescopic arm. When the equipment is parked, try to choose a clean and dry site, and cover the telescopic arm to prevent dust, mud and other impurities from invading. In addition, protective devices such as dust covers and sealing strips can be installed at key parts of the telescopic arm to effectively block the entry of impurities and foreign objects, and prevent the problem of telescopic arm not being smooth due to impurities and foreign objects from the source.
The telescopic arm of the excavator is not smooth. It is a more complicated problem, involving hydraulic systems, mechanical parts, lubrication systems, impurities and foreign objects.

In-depth Analysis of the Causes of the Unsmooth Telescopic Arm
Hydraulic System Failure
The hydraulic system is the core power source that drives the telescopic arm of the excavator, and its failure is one of the common reasons for the unsmooth telescopic arm. Hydraulic pump failure is more typical in the "Excavator Hydraulic Pump Affecting the Working Case of Telescopic Arm". When the internal parts of the hydraulic pump are severely worn, such as gear wear and plunger strain, the hydraulic pump output flow and pressure will be insufficient. When the telescopic arm is working, it cannot obtain sufficient hydraulic power support, and it will extend or retract slowly, jam or even fail to move. In addition, if the overflow valve in the hydraulic system fails, the system pressure cannot be adjusted normally, resulting in excessive or low pressure, which will also affect the normal operation of the telescopic arm. Excessive pressure may make the telescopic arm move too quickly and difficult to control; while too low pressure will make the telescopic arm lack power and move slowly.
Telescopic arm mechanical parts wear
Long-term high-intensity operation will cause serious wear of the mechanical parts of the telescopic arm. The slider, slide rail and other parts of the telescopic arm are prone to wear and deformation in frequent relative movements. In the "Analysis of the Slider Wear of the Excavator Telescopic Arm Leading to Smoothness", after the slider is worn, the matching gap between it and the slide rail increases, which will cause the telescopic arm to shake and jam during movement. Moreover, the connecting parts of the telescopic arm, such as the pin shaft and pin sleeve, are also prone to wear due to long-term exposure to large shear forces. When the gap between the pin shaft and the pin sleeve is too large, it will affect the connection stability between the sections of the telescopic arm, which will cause the telescopic arm to move unsmoothly, and in severe cases may even cause safety accidents.
Lubrication system problems
Good lubrication is the key to ensuring the normal operation of the mechanical parts of the telescopic arm. If the lubrication system fails, it will aggravate the wear of mechanical parts and cause the telescopic arm to operate unsmoothly. Insufficient grease is a common problem. In some construction sites with harsh working environments and high dust content, the grease is easily washed away or deteriorated, but the operator fails to replenish and replace it in time. In the "Excavator Telescopic Arm Failure Case", due to the long-term lack of sufficient grease, the friction between the slider and the slide rail of the telescopic arm increased, which not only made the telescopic arm difficult to move, but also generated abnormal noise and accelerated the wear of parts. In addition, the quality of grease is also crucial. If grease that does not meet the specifications is used, its lubrication performance cannot meet the working requirements of the telescopic arm, which will also cause the telescopic arm to operate unsmoothly.
Impurity contamination and foreign body interference
The operating environment of the excavator is complex, and impurities such as dust and sand can easily enter the internal structure of the telescopic arm. These impurities will accumulate between the slider and the slide rail, in the pipelines and valve bodies of the hydraulic system, and hinder the normal movement of the telescopic arm. In the "Analysis of Impurities Causing Failure of Excavator Telescopic Arm", after impurities enter the hydraulic system, they may block key parts such as hydraulic oil filters and throttle holes, affect the normal circulation of hydraulic oil, cause unstable pressure in the hydraulic system, and then affect the movement of the telescopic arm. In addition, foreign objects at the construction site, such as fallen stones and tools, may get stuck between the sections of the telescopic arm, causing the telescopic arm to be blocked when extending or retracting, and unable to work normally.

If the overflow valve is severely damaged and cannot be repaired, a new overflow valve should be replaced. After the repair is completed, the hydraulic system should be fully pressure tested and flow regulated to ensure that the hydraulic system can stably and reliably provide power support for the telescopic arm.
Repair and replacement of mechanical parts
For the wear problem of the mechanical parts of the telescopic arm, if the slider is lightly worn, the slider can be polished and repaired to make its surface smooth and restore normal cooperation with the slide rail. If the slider is severely worn, a new slider should be replaced in time. When replacing the slider, choose a product that is consistent with the specifications of the original equipment, ensure that it is installed correctly, and adjust the gap between the slider and the slide rail. For worn pins and pin sleeves, they should be replaced in time. When installing new pins and pin sleeves, apply an appropriate amount of grease to ensure flexible rotation of the connection parts. At the same time, conduct a comprehensive inspection of other mechanical parts of the telescopic arm, repair or replace problematic parts, and ensure the integrity and stability of the mechanical structure of the telescopic arm.
Lubrication system maintenance and improvement
Strengthen the maintenance of the lubrication system. Regularly add grease to each lubrication point of the telescopic arm to ensure that the grease filling amount is sufficient. Select grease with reliable quality and in line with the equipment use requirements, and reasonably adjust the grease filling cycle according to different operating environments and working conditions. At the same time, regularly check and clean the pipelines of the lubrication system to prevent pipeline blockage or leakage. Filters can be installed in the lubrication system to further improve the cleanliness of the grease and reduce the wear of impurities on mechanical parts. By improving the maintenance and improvement measures of the lubrication system, good lubrication guarantees are provided for the smooth operation of the telescopic arm.
Impurity and foreign matter cleaning and prevention
Timely clean up impurities and foreign matter inside and outside the telescopic arm to keep the equipment clean. Before the operation, clean up the construction site to avoid the accumulation of debris around the excavator and reduce the possibility of impurities and foreign objects entering the telescopic arm. When the equipment is parked, try to choose a clean and dry site, and cover the telescopic arm to prevent dust, mud and other impurities from invading. In addition, protective devices such as dust covers and sealing strips can be installed at key parts of the telescopic arm to effectively block the entry of impurities and foreign objects, and prevent the problem of telescopic arm not being smooth due to impurities and foreign objects from the source.
The telescopic arm of the excavator is not smooth. It is a more complicated problem, involving hydraulic systems, mechanical parts, lubrication systems, impurities and foreign objects. Through an in-depth understanding of the content related to long-tail keywords such as "Analysis of the causes of telescopic arm jamming of excavators" and "Key points of maintenance skills for telescopic arms of excavators", scientific troubleshooting methods and effective solutions can be adopted to repair faults in a timely and accurate manner, ensure the smooth operation of the telescopic arm of the excavator, improve the operating efficiency and safety of the excavator, and provide strong support for the smooth progress of engineering construction. During the operation of the excavator, the telescopic arm undertakes the key extension and retraction tasks, and its smoothness directly affects the operating efficiency and accuracy of the excavator. Once the telescopic arm of the excavator is not smooth, it is like setting an obstacle to the normal operation of the equipment, which will not only reduce the working efficiency, but also cause additional damage to the equipment. In-depth exploration of the "Analysis of the Causes of the Excavator Telescopic Arm Jam" and mastering effective solutions are crucial to ensure the efficient and stable operation of the excavator.
In-depth Analysis of the Causes of the Unsmooth Telescopic Arm
Hydraulic System Failure
The hydraulic system is the core power source that drives the telescopic arm of the excavator, and its failure is one of the common reasons for the unsmooth telescopic arm. Hydraulic pump failure is more typical in the "Excavator Hydraulic Pump Affecting the Working Case of Telescopic Arm". When the internal parts of the hydraulic pump are severely worn, such as gear wear and plunger strain, the hydraulic pump output flow and pressure will be insufficient. When the telescopic arm is working, it cannot obtain sufficient hydraulic power support, and it will extend or retract slowly, jam or even fail to move. In addition, if the overflow valve in the hydraulic system fails, the system pressure cannot be adjusted normally, resulting in excessive or low pressure, which will also affect the normal operation of the telescopic arm. Excessive pressure may make the telescopic arm move too quickly and difficult to control; while too low pressure will make the telescopic arm lack power and move slowly.
Telescopic arm mechanical parts wear
Long-term high-intensity operation will cause serious wear of the mechanical parts of the telescopic arm. The slider, slide rail and other parts of the telescopic arm are prone to wear and deformation in frequent relative movements. In the "Analysis of the Slider Wear of the Excavator Telescopic Arm Leading to Smoothness", after the slider is worn, the matching gap between it and the slide rail increases, which will cause the telescopic arm to shake and jam during movement. Moreover, the connecting parts of the telescopic arm, such as the pin shaft and pin sleeve, are also prone to wear due to long-term exposure to large shear forces. When the gap between the pin shaft and the pin sleeve is too large, it will affect the connection stability between the sections of the telescopic arm, which will cause the telescopic arm to move unsmoothly, and in severe cases may even cause safety accidents.
Lubrication system problems
Good lubrication is the key to ensuring the normal operation of the mechanical parts of the telescopic arm. If the lubrication system fails, it will aggravate the wear of mechanical parts and cause the telescopic arm to operate unsmoothly. Insufficient grease is a common problem. In some construction sites with harsh working environments and high dust content, the grease is easily washed away or deteriorated, but the operator fails to replenish and replace it in time. In the "Excavator Telescopic Arm Failure Case", due to the long-term lack of sufficient grease, the friction between the slider and the slide rail of the telescopic arm increased, which not only made the telescopic arm difficult to move, but also generated abnormal noise and accelerated the wear of parts. In addition, the quality of grease is also crucial. If grease that does not meet the specifications is used, its lubrication performance cannot meet the working requirements of the telescopic arm, which will also cause the telescopic arm to operate unsmoothly.
Impurity contamination and foreign body interference
The operating environment of the excavator is complex, and impurities such as dust and sand can easily enter the internal structure of the telescopic arm. These impurities will accumulate between the slider and the slide rail, in the pipelines and valve bodies of the hydraulic system, and hinder the normal movement of the telescopic arm. In the "Analysis of Impurities Causing Failure of Excavator Telescopic Arm", after impurities enter the hydraulic system, they may block key parts such as hydraulic oil filters and throttle holes, affect the normal circulation of hydraulic oil, cause unstable pressure in the hydraulic system, and then affect the movement of the telescopic arm. In addition, foreign objects at the construction site, such as fallen stones and tools, may get stuck between the sections of the telescopic arm, causing the telescopic arm to be blocked when extending or retracting, and unable to work normally.
Methods for troubleshooting the problem of telescopic arm not working smoothly
Hydraulic system troubleshooting
When it is found that the telescopic arm of the excavator is not working smoothly, the hydraulic system should be thoroughly checked first. Use professional hydraulic testing equipment to test the output pressure and flow of the hydraulic pump, and compare the test data with the standard parameters of the equipment. If the pressure and flow are lower than the standard value, it is likely that the hydraulic pump has failed, and it is necessary to further disassemble and check the wear of the internal parts of the hydraulic pump. At the same time, check the working status of the overflow valve, and observe the movement changes of the telescopic arm by adjusting the pressure setting value of the overflow valve to determine whether the overflow valve is working properly. In addition, check whether there is leakage in the hydraulic system pipeline, whether the oil level and oil quality of the hydraulic oil are normal, and ensure that the hydraulic system can provide stable and sufficient power for the telescopic arm.
Mechanical parts inspection
Carefully inspect the mechanical parts of the telescopic arm. Observe whether the movement between the sections of the telescopic arm is smooth during the extension and retraction process, and whether there is shaking or jamming. Focus on checking the wear of the slider and the slide rail. The degree of wear can be judged by measuring the gap between the slider and the slide rail. If the gap exceeds the normal range, it is necessary to replace the slider or repair the slide rail in time. For the connection parts such as the pin shaft and the pin sleeve, check whether the connection is firm and whether there is any looseness. Use professional tools to measure the matching clearance between the pin shaft and the pin sleeve. If the clearance is too large, the worn pin shaft or pin sleeve should be replaced in time to ensure that the connection between the mechanical parts of the telescopic arm is tight and the movement is smooth.
Lubrication system inspection
When troubleshooting the lubrication system, first check whether there is enough grease at the grease filling point. This can be judged by opening the grease filling nozzle and observing the outflow of grease. If the grease is insufficient, it should be replenished in time with grease that meets the specifications. At the same time, check the quality of the grease and observe whether its color and texture are normal. If the grease changes color, becomes thinner or contains impurities, it means that the grease has deteriorated and the lubrication system needs to be thoroughly cleaned and replaced with new grease. In addition, it is also necessary to check whether the pipeline of the lubrication system is unobstructed, whether there is any blockage or leakage, and ensure that the grease can reach all parts that need lubrication smoothly.
Impurities and foreign matter inspection
Carefully check the external and internal structure of the telescopic arm to see if there are any foreign objects stuck between the sections of the telescopic arm. For some parts that are difficult to observe directly, tools such as flashlights can be used for auxiliary lighting. If foreign objects are found, they should be carefully removed to avoid secondary damage to the telescopic arm during the removal process. At the same time, check the filter of the hydraulic system to see if there are a lot of impurities accumulated on the filter. If the filter is seriously blocked, it is necessary to replace the filter in time and clean the hydraulic system to prevent impurities from continuing to damage the system and affect the normal operation of the telescopic arm.
Measures to solve the problem of unsmooth telescopic arm operation
Repair of hydraulic system faults
For hydraulic system faults, if the hydraulic pump is severely worn, it is necessary to disassemble the hydraulic pump and replace the worn parts, such as gears, plungers, etc. After replacing the parts, the hydraulic pump should be debugged to ensure that its output pressure and flow return to normal. For overflow valve failure, it can be repaired or replaced according to the specific situation. During repair, the overflow valve should be cleaned and adjusted so that it can regulate the system pressure normally. If the overflow valve is severely damaged and cannot be repaired, a new overflow valve should be replaced. After the repair is completed, the hydraulic system should be fully pressure tested and flow regulated to ensure that the hydraulic system can stably and reliably provide power support for the telescopic arm.
