1. It has been used for a long time, the oil seal is normal and worn.

处理计划：更换新的油封。

Treatment plan: replace the oil seal with a new one.

2.长时间未更换液压油，或者滤芯的质量不合格。液压油变脏，油封加速。

2. The hydraulic oil is not replaced for a long time, or the quality of the filter element is unqualified. The hydraulic oil becomes dirty and the oil seal accelerates.

处理计划：尽快更换液压油和滤芯。

Treatment plan: replace hydraulic oil and filter element as soon as possible.

3.液压油会变质或乳化，降低润滑性能，并加速油封的磨损。

3. The hydraulic oil will deteriorate or emulsify, reduce the lubricating performance and accelerate the wear of oil seal.

处理计划：尽快更换液压油和滤芯。在严重的情况下，需要清洁系统。

Treatment plan: replace hydraulic oil and filter element as soon as possible. In severe cases, the system needs to be cleaned.

4.传动轴失去动平衡，摆动量增加，主轴油封偏心。

4. The transmission shaft loses dynamic balance, the swing increases, and the main shaft oil seal is eccentric.

处理计划：快速固定或更换驱动轴。

Treatment plan: fix or replace the drive shaft quickly.

5.泵支架松动，焊缝松动或泵固定螺栓松动会导致液压泵整体振动和油封磨损。

5. Loose pump bracket, weld or pump fixing bolt will lead to overall vibration and oil seal wear of hydraulic pump.

处理计划：经常检查以隐患，防止和避免故障。

Treatment plan: regular inspection to eliminate hidden dangers, prevent and avoid failures.

6.系统不稳定，回油管或散热器堵塞，导致泵电机腔中的压力升高，并且油封泄漏。

6. The system is unstable and the oil return pipe or radiator is blocked, which leads to the pressure increase in the pump motor cavity and the oil seal leaks.

处理计划：阻塞并稳定回油周期。

Treatment plan: eliminate blockage and stabilize oil return period.

7.散热器不会散发热量，从而导致机油温度过高，粘度和润滑性降低，油封过热以及密封件损坏。

7. The radiator will not emit heat, resulting in high oil temperature, reduced viscosity and lubricity, overheated oil seal and seal damage.

方案：及时散热器故障，尽快冷却系统并防止泵马达磨损。如有必要，请停止并关闭电源，并用水冲洗泵马达和散热器外壳以冷却。

Solution: eliminate radiator failure in time, cool the system as soon as possible and prevent pump motor wear. If necessary, stop and turn off the power supply and flush the pump motor and radiator housing with water to cool.

8.冬季预热不足，机油温度太低，机油和油封未达到工作温度。

8. Insufficient preheating in winter, the oil temperature is too low, and the oil and oil seal do not reach the working temperature.

方案：起动车辆时，以空转速度停止油箱1020分钟，并在燃油温度正常时启动油箱。

Solution: when starting the vehicle, stop the fuel tank at idle speed for 10 to 20 minutes and start the tank when the fuel temperature is normal.
