Reason 1: the oil seal is worn normally for a long time.
處理方案：給小型混凝土攪拌車(chē)更換新油封。
Treatment plan: replace new oil seal for small concrete mixer.
★原因2：液壓油長(cháng)期沒(méi)有更換或濾芯質(zhì)量不合格，液壓油過(guò)臟，加速油封磨損。
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.
處理方案：盡快更換小型混凝土攪拌車(chē)液壓油和濾芯。
Treatment plan: replace hydraulic oil and filter element of small concrete mixer as soon as possible.
★原因3：液壓油變質(zhì)或乳化，潤滑性能下降，加速油封磨損。
Reason 3: deterioration or emulsification of hydraulic oil, decline of lubricating performance and acceleration of oil seal wear.
處理方案：盡快更換液壓油和濾芯，嚴重時(shí)需要清洗系統。
Treatment plan: replace the hydraulic oil and filter element as soon as possible, and clean the system if it is serious.
★原因4：傳動(dòng)軸動(dòng)平衡失效，擺動(dòng)量大，引起主軸擺動(dòng)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.
處理方案：及時(shí)校正或更換小型混凝土攪拌車(chē)傳動(dòng)軸。
Treatment plan: timely correct or replace the drive shaft of small concrete mixer.
★原因5：泵支架松動(dòng)、開(kāi)焊或泵固定螺栓松動(dòng)，引起液壓泵整體抖動(dòng)，油封磨損。
Cause 5: loose pump bracket, open welding or loose pump fixing bolt, causing overall shaking of hydraulic pump and wear of oil seal.
處理方案：經(jīng)常檢查，排除隱患，預防和避免故障。
Treatment plan: regular inspection, elimination of hidden dangers, prevention and avoidance of faults.
★原因6：系統回油不暢，回油管或散熱器堵塞，造成泵馬達殼腔壓力增大，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.
處理方案：排除堵塞，保持小型混凝土攪拌車(chē)回油循環(huán)順暢。
Treatment scheme: remove the blockage and keep the oil return circulation of small concrete mixer truck smooth.
★原因7：散熱器不散熱，造成油溫過(guò)高，粘度和潤滑性下降、油封過(guò)熱密封失效。
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：及時(shí)排除散熱器故障，盡快為小型混凝土攪拌車(chē)系統降溫，防止泵馬達磨損。必要時(shí)停車(chē)熄火，用水沖泵馬達和散熱器殼體降溫。
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：冬季起車(chē)時(shí)預熱不足，油溫過(guò)低，油液和油封沒(méi)有達到較佳工作溫度。
Reason 8: insufficient preheating, too low oil temperature, and poor oil and oil seal operating temperature in winter.
