★原因1：使用时间长，油封正常磨损。

Reason 1: the oil seal is worn normally for a long time.

处理方案：给小型混凝土搅拌车更换新油封。

Treatment plan: replace new oil seal for small concrete mixer.

★原因2：液压油长期没有更换或滤芯质量不合格，液压油过脏，加速油封磨损。

Reason 2: the hydraulic oil has not been replaced for a long time or the quality of the filter element is unqualified, and the hydraulic oil is too dirty, which accelerates the oil seal wear.

处理方案：尽快更换小型混凝土搅拌车液压油和滤芯。

Treatment plan: replace hydraulic oil and filter element of small concrete mixer as soon as possible.

★原因3：液压油变质或乳化，润滑性能下降，加速油封磨损。

Reason 3: deterioration or emulsification of hydraulic oil, decline of lubricating performance and acceleration of oil seal wear.

处理方案：尽快更换液压油和滤芯，严重时需要清洗系统。

Treatment plan: replace the hydraulic oil and filter element as soon as possible, and clean the system if it is serious.

★原因4：传动轴动平衡失效，摆动量大，引起主轴摆动油封偏磨。

Cause 4: the dynamic balance of the transmission shaft is invalid and the swing momentum is large, which causes eccentric wear of the oil seal of the spindle swing.

处理方案：及时校正或更换小型混凝土搅拌车传动轴。

Treatment plan: timely correct or replace the drive shaft of small concrete mixer.

★原因5：泵支架松动、开焊或泵固定螺栓松动，引起液压泵整体抖动，油封磨损。

Cause 5: loose pump bracket, open welding or loose pump fixing bolt, causing overall shaking of hydraulic pump and wear of oil seal.

处理方案：经常检查，排除隐患，预防和避免故障。

Treatment plan: regular inspection, elimination of hidden dangers, prevention and avoidance of faults.

★原因6：系统回油不畅，回油管或散热器堵塞，造成泵马达壳腔压力增大，引起油封漏油。

Cause 6: the oil return of the system is not smooth, and the oil return pipe or radiator is blocked, resulting in the increase of the pressure in the pump motor housing cavity and the oil seal leakage.

处理方案：排除堵塞，保持小型混凝土搅拌车回油循环顺畅。

Treatment scheme: remove the blockage and keep the oil return circulation of small concrete mixer truck smooth.

★原因7：散热器不散热，造成油温过高，粘度和润滑性下降、油封过热密封失效。

Reason 7: the radiator does not dissipate heat, resulting in high oil temperature, decreased viscosity and lubricity, overheated oil seal and sealing failure.

方案：及时排除散热器故障，尽快为小型混凝土搅拌车系统降温，防止泵马达磨损。必要时停车熄火，用水冲泵马达和散热器壳体降温。

Solution: timely remove radiator failure, as soon as possible for small concrete mixer system cooling, prevent pump motor wear. If necessary, stop the engine, wash the pump motor and radiator housing with water to cool down.

★原因8：冬季起车时预热不足，油温过低，油液和油封没有达到较佳工作温度。

Reason 8: insufficient preheating, too low oil temperature, and poor oil and oil seal operating temperature in winter.本文由全自动混凝土搅拌车整理发布，您是不是对这些内容有所了解了呢?更多的内容请点击：/我们会有更多精彩内容等你查看。This article is organized and released by the automatic concrete mixer truck.
