如果使用时间过长，油封会磨损。方案：只需更换新的油封即可。如果长时间不更换机油，则滤芯的质量会下降，机油会变得太脏，加速油封的磨损。方案：尽快更换液压油和滤芯。
If used for too long, the oil seal will wear. Solution: just replace the new oil seal. 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 accelerated. Solution: replace the hydraulic oil and filter element as soon as possible.
主轴摆动油封磨损，因为驱动轴不平衡且剧烈振动。处理方案：及时纠正并更换轴。
The spindle swing oil seal is worn because the drive shaft is unbalanced and vibrates violently. Solution: correct and replace the shaft in time.
液压油将变质并乳化，从而降低润滑性能并加速油封的磨损。
The hydraulic oil will deteriorate and emulsify, which will reduce the lubrication performance and accelerate the wear of the oil seal.

方案：尽快更换液压油和滤芯。在严重的情况下，应清洁系统。
Solution: replace the hydraulic oil and filter element as soon as possible. In severe cases, clean the system.
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。
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.
方案：为防止和避免故障，请始终检查并自上料搅拌车可能出现的故障。
Solution: in order to prevent and avoid faults, always check and eliminate possible faults of self loading mixer truck.
自上料搅拌车系统的回油不畅，回油管和散热器被堵塞，这会增加电机壳体中的压力并导致油封泄漏。
The oil return from the feeding mixer system is not smooth, and the oil return pipe and radiator are blocked, which will increase the pressure in the motor housing and lead to oil seal leakage.
方案：堵塞物并稳定回油回路。
Solution: remove the blockage and stabilize the oil return circuit.
如果散热器不散热，则油的温度会过高，粘度和润滑性会降低，油封会过热，并且密封会失效。
If the radiator does not dissipate heat, the oil temperature will be too high, the viscosity and lubricity will be reduced, the oil seal will overheat and the seal will fail.
方案：散热器上的障碍物并冷却系统，以避免泵马达磨损。在严重的情况下，有必要停止发动机，将其关闭，并用水冲洗泵马达和散热器壳体，以达到冷却效果。
Solution: remove the obstacles on the radiator and cool the system to avoid wear of the pump motor. In severe cases, it is necessary to stop the engine, turn it off, and flush the pump motor and radiator housing with water to achieve cooling effect.
在冬季行驶时，由于预热不足，油温太低，并且油封和油封无法达到理想的工作温度。
When driving in winter, due to insufficient preheating, the oil temperature is too low, and the oil seal and oil seal cannot reach the ideal working temperature.
对策：启动时，停止油箱，以怠速运行1020分钟，并在油温恢复正常后更换油箱。
Countermeasures: when starting, stop the oil tank, run at idle speed for 10 to 20 minutes, and replace the oil tank after the oil temperature returns to normal.
小型自动搅拌车液压泵轴端的油封是易损件。严格遵守相关法规可以有效防止许多机油泄漏。如果遇到漏油问题，则需要冷静下来，找出引起问题的具体原因。
The oil seal at the shaft end of hydraulic pump of small automatic mixer is a vulnerable part. Strict compliance with relevant laws and regulations can effectively prevent many oil leaks. In case of oil leakage, you need to calm down and find out the specific cause of the problem.
