If the oil is not changed for a long time, the quality of the filter element will decline, the oil will become too dirty, and the wear of the oil seal will be faster. Solution: replace the hydraulic oil and filter element as soon as possible.

驱动轴失衡并剧烈振动，导致主轴摆动油封磨损。方案：及时固定并更换轴。

The drive shaft is unbalanced and vibrates violently, resulting in the wear of the main shaft swing oil seal. Solution: fix and replace the shaft in time.

液压油会变质和乳化，降低润滑性能并加速油封的磨损。方案：尽快更换液压油和滤芯。在严重的情况下，需要清洁系统。

The hydraulic oil will deteriorate and emulsify, reduce the lubrication performance and accelerate the wear of the oil seal. Solution: replace the hydraulic oil and filter element as soon as possible. In severe cases, the system needs to be cleaned.

泵支架松动，泵打开，泵固定螺栓松动，导致整个液压泵振动并磨损油封。方案：始终检查并全自动上料一体搅拌车发生故障的可能性，以防止并避免发生故障。

The pump support is loose, the pump is opened, and the pump fixing bolts are loose, resulting in vibration of the whole hydraulic pump and wear of the oil seal. Solution: always check and eliminate the possibility of failure of the fully automatic feeding integrated mixer to prevent and avoid failure.

自动上料一体搅拌车系统的回油不畅，回油管和散热器堵塞，导致电动机壳体内的压力升高，并且油封泄漏。方案：堵塞物并稳定回油回路。

The oil return of the automatic feeding integrated mixer system is not smooth, and the oil return pipe and radiator are blocked, resulting in the increase of pressure in the motor housing and the leakage of oil seal. Solution: remove the blockage and stabilize the oil return circuit.

如果散热器不散热，油的温度将变得太高，粘度和润滑性将降低，油封将过热并且密封将无法工作。

If the radiator does not dissipate heat, the oil temperature will become too high, the viscosity and lubricity will be reduced, the oil seal will overheat and the seal will not work.

方案：散热器上的障碍物并冷却系统，以防止泵马达磨损。在严重的情况下，有必要停止和停止发动机，并用水冲洗泵的电动机和散热器壳体以达到冷却效果。

Solution: remove obstacles from the radiator and cool the system to prevent wear of the pump motor. In severe cases, it is necessary to stop and stop the engine and flush the pump motor and radiator housing with water to achieve cooling effect.

在冬季运行期间，由于预热不足，油温过低，油封和油封无法达到理想的工作温度。对策：启动时停止油箱，以怠速运转1020分钟，并在机油温度恢复正常时更换油箱。

During winter operation, due to insufficient preheating and low oil temperature, the oil seal and oil seal cannot reach the ideal working temperature. Countermeasures: stop the oil tank when starting, run at idle speed for 10 to 20 minutes, and replace the oil tank when the oil temperature returns to normal.

自动上料一体搅拌车的液压泵轴端的油封很脆弱。严格遵守相关法规可以有效防止许多机油泄漏。如果遇到漏油，则需要冷静下来并确定问题的具体原因。

The oil seal at the shaft end of the hydraulic pump of the automatic feeding integrated mixer is very fragile. Strict compliance with relevant laws and regulations can effectively prevent many oil leaks. If you encounter an oil leak, you need to calm down and determine the specific cause of the problem.
