升降貨梯在行駛中急轉(zhuǎn)彎時(shí)常出現(xiàn)前輪轉(zhuǎn)向遲緩的故障現(xiàn)象，根據(jù)轉(zhuǎn)向系統(tǒng)的工作原理，可判定此故障是由于液壓轉(zhuǎn)向系統(tǒng)的容積效率下降和系統(tǒng)壓力過(guò)低而引起的。下面濟(jì)南天銳升降機(jī)械的技術(shù)人員給大家介紹如何防止這類事件的發(fā)生。

1、檢查升降貨梯http://www.jntr168.com/液壓轉(zhuǎn)向系統(tǒng)的外部是否有滲漏，說(shuō)明有外部漏油，主要表現(xiàn)為液壓油損失較大，系統(tǒng)壓力下降，轉(zhuǎn)向缸及馬達(dá)的運(yùn)動(dòng)不平穩(wěn)，致使轉(zhuǎn)轉(zhuǎn)向遲緩無(wú)力，甚至無(wú)法轉(zhuǎn)向。油管接頭配合不當(dāng)、密封不良及管路破裂；密封件配合不當(dāng)、磨損、老化或損壞；油溫過(guò)高，從而增加泄漏。當(dāng)發(fā)現(xiàn)外部漏油時(shí)，應(yīng)及時(shí)進(jìn)行維修。   
Check whether the cargo lifter external hydraulic steering system for leaks, indicating there is an external leak, mainly for large hydraulic oil loss, the system pressure drop, steering cylinder and motor movement is not smooth,resulting in turn turned slow and weak, can not even steering. Tubing connector mismatch, poor sealing and pipeline rupture; seals fit properly, wear, aging or damage; high oil temperature, thereby increasing leakage. When they find an external leak, should be repaired promptly.
        
2、升降貨梯液壓油的質(zhì)量將直接影響轉(zhuǎn)向系統(tǒng)的工作狀態(tài)。液壓油過(guò)少，會(huì)使液壓泵因供油不足而導(dǎo)致機(jī)器的轉(zhuǎn)向動(dòng)作遲緩，故應(yīng)將液壓油添加至規(guī)定的液面；當(dāng)液壓油不干凈或油箱內(nèi)有異物時(shí)，雜質(zhì)進(jìn)入液壓系統(tǒng)后會(huì)造成密封件損壞或使元件配合副損傷，使內(nèi)泄漏增加，從而引起轉(zhuǎn)向遲緩。為此，須對(duì)液壓油的油質(zhì)進(jìn)行認(rèn)真的檢查。
Quality hydraulic oil cargo lifter will directly affect the working status of the steering system. Hydraulic oil is too small, the pump will cause the machine due to lack of oil supply and slow steering action, it should add hydraulic oil to the required level; when a foreign body in the hydraulic oil tank is not clean or impurities into the hydraulic system after can cause damage to the seal or the element with the vice injury, the internal leakage increases, causing slow turn. To this end, on the oil hydraulic oil must be carefully checked.
       
3、即使是少量的空氣進(jìn)入了升降貨梯http://www.jntr168.com/液壓系統(tǒng)，也會(huì)對(duì)系統(tǒng)產(chǎn)生較大的影響，使轉(zhuǎn)向缸出現(xiàn)爬行，降低液壓系統(tǒng)的效率，從而引起轉(zhuǎn)向遲緩。空氣進(jìn)入液壓系統(tǒng)的途徑有：轉(zhuǎn)向泵吸油管的接頭出松弛或油管破裂；轉(zhuǎn)向泵密封不良；油箱內(nèi)的油面過(guò)低，使吸油管或回油管露出液面；液壓油油質(zhì)不佳。如果轉(zhuǎn)向泵內(nèi)漏嚴(yán)重，也可造成大連移動(dòng)式升降平臺(tái)轉(zhuǎn)向遲緩。引起轉(zhuǎn)向泵內(nèi)泄漏的一個(gè)重要原因是，泵的轉(zhuǎn)子和葉片的側(cè)面與側(cè)板端面之間的間隙過(guò)大。
Even a small amount of air into the cargo lifter hydraulic system, will have a greater impact on the system, the steering cylinder creeping, reducing the efficiency of the hydraulic system, causing slow turn. Way air into the hydraulic system are: steering pump suction pipe joints of relaxation or pipeline rupture; steering pump seal bad; the oil tank is too low, so that the suction pipe or return pipe exposed surface; poor quality hydraulic oil. If the steering pump leak serious, it can cause the steering Dalian mobile lifting platform slow. An important reason for leakage in the pump caused by steering is that the gap side of the pump rotor and vanes between the end surface of the side plate is too large.
