FAQ:
How to check if the hydraulic system of a track excavator is functioning properly?

To check if the hydraulic system is functioning properly, observe the color and viscosity of the hydraulic oil, check the oil level in the hydraulic tank, look for leaks in the lines and fittings, and test the output pressure of the hydraulic pump.

What is the function of the hydraulic pump pressure relief valve?

The pressure relief valve protects the hydraulic system from damage caused by excessive pressure by releasing excess hydraulic oil when the pressure exceeds the set value.

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 reasons why the excavator can rotate when starting, but cannot start?

1.There is no oil in the fuel tank.

 

2.The fuel filter and oil-water separator are blocked.

 

3.The low-pressure oil circuit does not supply oil.

 

4.The injection pump does not pump oil.

 

5.There is air in the oil circuit.

 

6.The valve timing is misaligned. The opening time of the valve is not coordinated with the stroke of the piston in the cylinder. For example, when the piston makes a compression stroke in the cylinder, the intake and exhaust valves are open, and fresh air is driven out of the cylinder, so that there is no combustion gas in the cylinder and it cannot start.

 

7.The solenoid valve of the injection pump is broken and is in a closed state, and the diesel cannot enter the high-pressure chamber.
