Excavators must be familiar to all of us, so do you know the Jehol maintenance excavator? I don't know. Let's go with Xiaobian.
1. Fuel filter element and additional fuel filter element should be replaced after 250 hours of operation of the new engine, and the clearance of the engine valve should be checked.
2. Daily maintenance; check, wash or change the air filter element; clean the cooling system interior; check and tighten the caterpillar plate bolts; check and moderately adjust the back tension of the caterpillar; check the intake heater; replace bucket teeth; adjust the bucket clearance; check the liquid level of the front window; check and adjust the air conditioning; clean and control the indoor floor; replace the filter element of the crusher (optional accessories).
When cleaning the cooling system, after the engine is fully cooled, slowly unscrew the nozzle cover, release the internal pressure of the water tank, and then release the water; do not clean the engine while working, the high-speed rotating fan will cause risks; when cleaning or replacing the coolant, the machine should be parked on the horizontal ground; replace the coolant and corrosion preventer according to Table 3. The ratio of antifreeze to water should be increased.
3. Because the excavator's elongated arm is longer, heavier and more inertial than the standard arm, the operation is lighter than the standard arm. The operation process should be smooth. The action should not be too fast or too violent. The emergency brake bucket capacity should not be allocated according to the factory specifications. It is strictly forbidden to replace the large capacity bucket.
Particular attention to spare parts maintenance:
Bearing is an important part of mechanical equipment, its main function is to support the mechanical rotating body, reduce the conflict coefficient in its movement process, and ensure its inversion accuracy. Bearings can be classified into rolling bearings and sliding bearings according to the conflict nature of moving elements. Rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibration and noise are larger, and their prices are higher.
Sliding Bearing: Bearing operating under sliding conflict. Sliding bearings work smoothly, reliably and noiselessly. Under the condition of smooth liquid, the sliding surface is separated by smooth oil without direct contact, and the loss of conflict and surface wear can be greatly reduced. The oil film also has the ability to absorb vibration, but the starting conflict resistance is larger.
