1： The insufficient oil supply of large concrete mixer leads to low output speed and torque
辦法：供油液壓泵吸油口過(guò)濾器堵塞，此時(shí)可清洗濾油器；油液鉆度過(guò)大，此時(shí)可更換適合的油液；軸向或徑向間隙過(guò)大等原因等造成，此時(shí)要研磨定子或其他有關(guān)零件，使軸向間隙符合要求。
Solution: if the filter at the oil suction port of the oil supply hydraulic pump is blocked, the oil filter can be cleaned; if the oil drill is too large, the suitable oil can be replaced; if the axial or radial clearance is too large, the stator or other relevant parts should be ground to make the axial clearance meet the requirements.
二：大型混凝土攪拌機液壓馬達的原動(dòng)機功率或轉速不當導致輸出轉速和輸出轉矩低
2： The output speed and torque of hydraulic motor of large-scale concrete mixer is low due to improper power or speed of prime mover
辦法：原動(dòng)機功率不匹配，此時(shí)需要更換原動(dòng)機，使之與液壓泵功率匹配；原動(dòng)機轉速低于額定轉速，此時(shí)可選用轉速滿(mǎn)足要求的原動(dòng)機。
Solution: if the prime mover power does not match, the prime mover needs to be replaced to match the power of the hydraulic pump; if the prime mover speed is lower than the rated speed, the prime mover with the rotational speed meeting the requirements can be selected.
三：大型混凝土攪拌機各連接處密封不嚴，有空氣混入
3： The joints of large-scale concrete mixer are not tightly sealed and air is mixed in
辦法：檢查和緊固各連接處，提高密封性能。
Solution: check and tighten the joints to improve the sealing performance.
四：工作介質(zhì)污染，液壓馬達內部通道被堵塞
4： The working medium is polluted and the internal channel of hydraulic motor is blocked
辦法：拆解，仔細清洗并更換清潔的工作介質(zhì)。
Solution: disassemble, carefully clean and replace clean working medium.
五：大型混凝土攪拌機配流盤(pán)和葉片磨損，內泄漏大
5： The valve plate and blade of large concrete mixer are worn and the internal leakage is large
辦法：修復或更換有關(guān)零件。
Solution: repair or replace the relevant parts.
六：大型混凝土攪拌機液壓系統中單向閥密封不良
6： Poor sealing of check valve in hydraulic system of large concrete mixer
辦法：修理單向閥閥座或更換有關(guān)零件，使閥座與鋼球嚴格密合。
Solution: repair the check valve seat or replace the relevant parts, so that the valve seat and steel ball are tightly closed.
七：液壓系統中溢流閥失靈
7： Overflow valve failure in hydraulic system
辦法：修理或更換溢流閥。
Solution: repair or replace the relief valve.
