Q&A

How to vent the hydraulic pump after installation?

The way to vent after installation is to slowly operate all functions of the hydraulic system until the air is exhausted, and check and maintain the hydraulic oil level during this process.

How to bleed air from the excavator's hydraulic system?

Start the excavator and let the hydraulic system run for a while. Operate all hydraulic functions to expel air, check the hydraulic tank oil level, and add hydraulic oil to ensure the system is full.

Digging powerlessness is one of the typical faults of excavators

Digging powerlessness can be divided into two situations: one is digging powerlessness, the engine does not hold back, and the load feels very light; the second is digging powerlessness, when the boom or dipper stick is extended to the bottom, the engine is seriously held back or even stalled.

 

①, digging powerlessness but the engine does not hold back. The magnitude of the digging force is determined by the output pressure of the main pump, and whether the engine holds back depends on the relationship between the oil pump absorption torque and the engine output torque. The engine does not hold back, indicating that the oil pump absorption torque is small and the engine load is light. If the working speed of the excavator is not obviously abnormal, the maximum output pressure of the main pump, that is, the system overflow pressure, should be checked in particular. If the overflow pressure measurement value is lower than the specified value, it indicates that the overload overflow valve setting value of the hydraulic circuit of the mechanism is incorrect, resulting in premature overflow of the mechanism and powerlessness. The machine can be adjusted by turning the adjustment screw.

 

②, digging powerlessness, engine holding back. The engine holding back indicates that the absorption torque of the oil pump is greater than the engine output torque, causing the engine to overload. This fault should first check whether the engine speed sensing system is normal, and the inspection method is similar to the engine inspection method described above. After the above detailed inspection and troubleshooting, the engine speed sensing system will resume normal function, the engine stalling phenomenon will disappear, and the digging force will return to normal.

What are the common reasons for the hydraulic pump not working?

The reasons for not working include power supply problems, low hydraulic oil level, filter blockage, hydraulic line leakage and pump internal component failure.
