The vane pump is broken for many reasons, but the common reasons are mainly in the following aspects. Dalan hydraulic small series has been summarized, for your reference only:
1. Research pump (burning plate):
Cause: The oil is too dirty, improperly installed, the water is in the oil, there are iron filings in the oil (new machines often occur), the oil temperature is high or the manufacturing precision of the parts is not enough.
2, loud noise:
1 Inlet air leak: O-ring seal failure, the screw is too long or the flange is too thin.
2 The filter is clogged and the oil flow is not enough.
3 The viscosity of the oil is too high: the weather is too cold or the grade is wrong.
4 Assembly error: When the position of the inlet and outlet is changed, the method and method are not proper or the seal ring is not installed and the pump core positioning is not inserted into the hole of the back cover.
3, the system has no pressure:
1Overflow valve failure: need to be cleaned or replaced
2 Pressure reducing valve failure: need to be cleaned or replaced
4. When the curve in the stator is corrugated in the shape of a washboard:
The main phenomenon is that the oil is not stable, the pressure is unstable, the pressure is too low, the noise is high, there is obvious metal knocking sound, and the squeaking sound caused by the compressed air is compressed. The reasons are as follows:
1 oil is too sticky and insufficient oil absorption.
2 The suction filter is clogged or too small, and the oil absorption area is not enough.
3 The oil level is too low and the oil is not in place.
5. If the hydraulic system exceeds the rated standard, the following conditions will occur:
1 The shell is broken.
2 The stator is broken.
3-axis fracture.
4 The screw is broken.
5 life is shortened.
Cause: If the oil in the tank is too dirty or the overflow valve and other functional valves are stuck after entering the iron filings, the pressure will increase indefinitely. If the "safety protection" design of the system is unreasonable or the "safety factor" is too low, It will cause the instantaneous pressure to exceed the standard. When the system pressure exceeds the rated standard, the internal parts of the pump core can not withstand the high pressure, which leads to the breakage of a certain part or the rapid shortening of the life.
Check the pressure: connect the pressure gauge at the inlet and outlet of the oil pump and observe the pressure under normal working conditions.
