Tips for excavator maintenance in summer
Posted: Jan 9th, '25, 22:36
The hot summer has quietly arrived. We have specially summarized how to maintain the hydraulic system of the excavator in summer and how the driver can spend the hot summer.
The movement of the excavator is complex. All mechanisms are often started, braked, reversed, and the load changes greatly. There are frequent impacts and vibrations. In addition, the temperature and astronomical position change greatly during field operations. In addition, the hot weather in summer, so according to the working characteristics and environmental characteristics of the excavator, the hydraulic system should be:
(1) Have high transmission efficiency to fully exert the power of the engine and the economy of fuel use.
(2) The hydraulic system and hydraulic components have sufficient reliability under the action of large load changes and sharp vibration and impact.
(3) Adjust the heavy and vibration-resistant cooler to reduce the total heat of the system so that the hydraulic oil temperature does not exceed 80 degrees or the temperature rise does not exceed 45 degrees when the main engine is working continuously.
(4) Since there is a lot of dust on the excavator site, the hydraulic oil is easily contaminated. Therefore, the sealing performance of the hydraulic system should be good, the hydraulic components should be less sensitive to oil contamination, and the entire hydraulic system should be equipped with an oil filter and dustproof device.
(5) Use hydraulic or electro-hydraulic servo control devices to set up automatic control systems for excavators, thereby further improving the technical performance of excavators and reducing the labor intensity of drivers.
To meet these requirements, the hydraulic system must ensure the following points:
(1) Ensure that the excavator boom, dipper and bucket can move independently and cooperate with each other to complete compound movements.
(2) The movement of the working device and the rotation of the turntable can be stopped independently and in compound movements.
(3) The left and right crawlers of the crawler excavator are driven separately, making the excavator easy to walk and turn flexibly, and can turn on the spot to check the sensitivity of the excavator.
(4) Ensure that all actions of the excavator are reversible and stepless.
(5) Ensure that the excavator works safely and reliably, and each actuator (hydraulic cylinder, hydraulic motor, etc.) has good overload protection; the slewing mechanism and walking device have reliable braking and speed limit; prevent the boom from falling due to its own weight and the whole machine from speeding down.
The weather is hot in summer. On the one hand, the driver's physical strength is greatly consumed and he is easily tired. On the other hand, the whole machine is also prone to defects due to the high temperature. Therefore, both must be adjusted in time, even if the excavator is added with oil suitable for summer and the cooling system is checked. Although the high temperature in summer is unbearable for both people and excavators, the excavator must be well maintained, so as to save the cost of excavator parts maintenance and increase the excavator's income. In summer, the air conditioner in the cab must also be repaired and adjusted, so that the driver's state can be better adjusted.
