一:大型自上料水泥攪拌車(chē)供油量不足導(dǎo)致輸出轉(zhuǎn)速和輸出轉(zhuǎn)矩低
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:大型自上料水泥攪拌車(chē)液壓馬達(dá)的原動(dòng)機(jī)功率或轉(zhuǎn)速不當(dāng)導(dǎo)致輸出轉(zhuǎn)速和輸出轉(zhuǎn)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(jī)功率不匹配,此時(shí)需要更換原動(dòng)機(jī),使之與液壓泵功率匹配;原動(dòng)機(jī)轉(zhuǎn)速低于額定轉(zhuǎn)速,此時(shí)可選用轉(zhuǎn)速滿(mǎn)足要求的原動(dòng)機(jī)。
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:大型自上料水泥攪拌車(chē)各連接處密封不嚴(yán),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(dá)內(nèi)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(xì)清洗并更換清潔的工作介質(zhì)。
Solution: disassemble, carefully clean and replace clean working medium.
五:大型自上料水泥攪拌車(chē)配流盤(pán)和葉片磨損,內(nèi)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(fù)或更換有關(guān)零件。
Solution: repair or replace the relevant parts.
六:大型自上料水泥攪拌車(chē)液壓系統(tǒng)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(yán)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(tǒng)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.
