With the arrival of spring, the temperature gradually rises, and the working environment of excavators has also changed. A good maintenance of excavators in spring is crucial to ensuring stable and efficient operation of equipment throughout the year. The following brings you spring maintenance points covering various key parts, interspersed with relevant long-tail keywords, to help you take full care of the excavator.
Engine: Spring care of power source
Change the oil and filter
After low temperature operation in winter, the oil performance may be reduced. In spring, the oil suitable for the current temperature should be replaced in time, and it is generally recommended to use multilevel oil, which can maintain good fluidity and lubricity at different temperatures. At the same time, replace the oil filter to prevent impurities from entering the engine and extend the service life of the engine. When choosing oil, it is necessary to follow the recommended specifications of the excavator engine model and the user manual, such as "Spring excavator engine maintenance tips", which emphasizes that the wrong oil selection may lead to increased engine wear. Operation, be sure to be carried out after the engine is cooled, first unscrew the oil drain bolt, drain the old oil, and then install a new filter, and finally add an appropriate amount of new oil to ensure that the oil level is within the normal scale range.
Check the air filter
In spring, the wind and sand are large, and the air filter is easy to jam. Check the air filter regularly and use compressed air to reverse blow the dust on the filter element from inside out. If the filter element is blocked seriously, it should be replaced in time. Clogged air filters will cause insufficient engine intake, resulting in inadequate combustion, reducing engine power, and increasing fuel consumption. For example, in some areas with frequent sandstorms, according to the "excavator air filter spring maintenance points", the air filter needs to be checked and cleaned every week to ensure the normal intake of the engine.
Clean the radiator
Spring all things recover, catkins, dust and other debris are easy to adhere to the surface of the radiator, affecting the heat dissipation effect. Use a brush or compressed air to carefully clean debris between the radiator plates to ensure smooth coolant circulation and prevent engine overheating. An overheated engine will not only reduce power output, but may also cause serious failures such as cylinder pulling. Follow the "spring excavator radiator cleaning method", in areas with harsh working environment, the radiator should be deeply cleaned every 100 hours or so.
Hydraulic systems: Maintenance for efficient operations
Check hydraulic fluid
Spring temperature rise, hydraulic oil viscosity will change. Check the hydraulic oil level to ensure that the oil level is within the specified range. At the same time, observe the color and transparency of hydraulic oil, if the oil is cloudy, black or emulsified, it needs to be replaced in time. Poor quality or deteriorated hydraulic oil will affect the pressure transmission of the hydraulic system, resulting in slow action, weak digging and other problems, which are detailed in the "excavator hydraulic system spring maintenance method". When replacing hydraulic oil, the old oil in the system should be drained, and the hydraulic tank should be cleaned if necessary.
Check hydraulic lines
Carefully check the connection parts of the hydraulic pipeline to see if there is loosening and leakage. In spring, the temperature difference between day and night is large, and the pipe joints may be loosened due to thermal expansion and cold contraction. Tighten loose joints in time, replace aging or damaged seals, and prevent hydraulic oil leakage. Hydraulic oil leakage will not only cause environmental pollution, but also may cause system failure due to insufficient oil, such as in the "spring excavator hydraulic pipeline investigation points" emphasized that daily inspection should focus on the parts that are easy to leak.
Test hydraulic pump and valve
After starting the excavator and running without load for a period of time, the output pressure of the hydraulic pump and the working performance of each control valve are tested. Professional pressure testing equipment can be used to check whether the pressure is within the specified range and whether the action of each valve is sensitive and accurate. If the pressure is abnormal or the valve is stuck, it should be repaired or replaced in time to ensure the stable operation of the hydraulic system.
Electrical systems: Critical maintenance of intelligent control
Check battery
Spring air humidity is relatively large, the battery is prone to leakage, corrosion and other problems. Check the battery electrolyte level. If the liquid level is too low, add distilled water to a proper height. Clean the battery electrode column and apply Vaseline to prevent corrosion. Use a multimeter to measure the battery voltage. Generally, the voltage before starting the battery should be about 24V (using a 12V dual-battery system as an example). If the voltage is too low, charge or replace the battery. Refer to the "Spring excavator battery maintenance points", regularly maintain the battery to ensure that its power is sufficient and stable power supply for the electrical system.
Check circuit
Carefully check the whole excavator car line to see if there is damage, aging, short circuit and other conditions. In the spring, small animals such as mice are frequently active and may bite the wiring. Organize the line, fix the loose wiring harness, and bandage or replace the damaged line in time. Once the line fails, it may cause some functions of the equipment to fail, and even cause serious consequences such as fire. There are relevant warning cases in the "Excavator Spring Electrical line Investigation Tips".
Service sensor
As mentioned earlier, sensors are crucial to the operation of excavators. In spring, all kinds of sensors should be cleaned and calibrated to ensure accurate data measurement. For example, pressure sensors, temperature sensors, etc., if the measurement data deviation is too large, the equipment control system will misjudge, affecting the safety and efficiency of the operation. According to the "Spring Excavator Sensor Maintenance Method", the sensor is regularly maintained to ensure its normal work.
Chassis and working equipment: basic maintenance for stable operation
Lubricate each hinge point
As the temperature rises in spring, the lubrication demand at each hinge point increases. Use the butter gun to inject appropriate grease into the hinge points of the boom, bucket rod, bucket and other parts to ensure flexible joint movement and reduce wear. Generally, every 20-30 hours of work needs to be lubricated, follow the "excavator spring hinge point lubrication points", can effectively extend the service life of the working device.
Inspection track
Check the track tension and adjust the track tension cylinder to make the track tightness moderate. Too loose track is easy to derail, too tight will accelerate track and drive wheel wear. At the same time, check whether the track plate is damaged or deformed, and replace it in time if there is a problem. It is mentioned in the "Spring excavator track Inspection and Maintenance Method" that different operating environments have slightly different requirements for track tension, which should be adjusted according to the actual situation.
Maintenance swivel
Rotary device is the key component of excavator to realize 360 degree rotation. Check the fastening of the bolts of the slewing support and add appropriate amount of gear oil. Run the equipment, observe whether the rotation is smooth, there is no abnormal noise, if the problem is found, timely maintenance, to ensure the normal operation of the rotation device.
Comprehensive and meticulous maintenance of excavators in spring, covering various key parts such as engine, hydraulic system, electrical system, chassis and working device, and strictly following the maintenance points corresponding to relevant long-tail keywords, can effectively improve equipment performance, reduce the occurrence of failures, and lay a solid foundation for efficient operation throughout the year.
