Maintenance Method of Oil Pump
1. Sediments on components and exposed piston rods can prevent dirt from entering the cylinder and damaging the piston, cylinder or seal.
Check the connecting parts of each thread and bolt regularly. If loose, tighten them immediately.
Frequently lubricate connecting rods to prevent rusting or abnormal wear in oil-free condition.

4 Regular replacement of hydraulic oil filter element and hydraulic oil return to ensure oil cleanliness and prolong the service life of cylinders.
Before the operation of the working device, the air in the cylinder should be exhausted and the full stretch test run of 5 strokes should be carried out before the operation with load.
6. Pay attention to the temperature of hydraulic oil. If the oil temperature is too high, the seal will be damaged or deformed. Permanent deformation, or even complete destruction.
After 7 years of work, the excavator should stop on the flat ground and the piston rod should be completely restored. Therefore, the large cylindrical cavity ensures that all hydraulic cylinders return to the tank to ensure that the cylinder does not withstand pressure.
Extended arm excavator
This newly bought excavator is not very workload, why is it always bad, you know? In daily work, the excavator accumulated faults due to long-term improper operation. As a excavator driver, have you ever made the following mistakes?
1. Operation of the working device before full recovery
When the working device of excavator is not fully restored, the excavator bucket is prone to impact rock, and the cylinder piston rod produces a larger load, which results in damage to the cylinder and cracking around the pin shaft.
2. Extension of cylinder block tie rod to excavation limit
Hydraulic cylinder excavator is telescopic to the end of the excavation operation. In this case, the cylinder and rack will produce a larger load, impact bucket teeth, impact each pin, may cause damage in the cylinder, but also affect other hydraulic components.
3 Excavator does not stand steadily when starting
This is a common situation that we often encounter. The uneven road surface (such as gravel road surface) will cause uneven force under the frame and damage the frame if the excavator does not stop working for a long time. In this case, it is better to lay some soil under it to make the ground flat, so that it can be operated again.
4. The frequency of crushing hammer is too high
Piston rod ruptures for a long time, high frequency vibration and excessive stress easily cause bending fracture of piston rod.
In order to lengthen the arm of the excavator to work for a long time, usually to do these small things, excavator is the excavator brother's tool to make money, but also comrades-in-arms, together rain and wind, but also to protect the machine.
