| Air bubbles in the oil | Supplementary fluids or structural measures to be taken back to the oil port dipped below the oil surface | |
| Pump speed too high | Choose the recommended speed range | |
| Pump pressure is too high | The following ng step-down to the rated pressure | |
| Shaft seal leak | Replace oil seal | |
| Cross Degree Hair Hot | High oil temperature | Improve the fuel tank or add cooler cooling conditions the oil temperature control within the recommended range of normal operating oil temperature |
| Oil viscosity is too low, too large within the vent | Choose the recommended oil viscosity work | |
| Working pressure is too high | The following step-down to the rated pressure | |
| Pump oil return port directly to the population | Oil return port connected to the tank below the liquid level | |
| Shake Move Cross Large | Pump shaft and motor shaft misalignment | Reinstall meet the specification required accuracy |
| Mounting screws loose | Tighten the screws | |
| Speed or pressure is too high | Adjusted to within the range of allowable | |
