升降貨梯在行駛中急轉彎時常出現前輪轉向遲緩的故障現象，根據轉向系統的工作原理，可判定此故障是由于液壓轉向系統的容積效率下降和系統壓力過低而引起的。下面濟南天銳升降機械的技術人員給大家介紹如何防止這類事件的發生。

1、檢查升降貨梯http://www.weheartgrub.com/液壓轉向系統的外部是否有滲漏，說明有外部漏油，主要表現為液壓油損失較大，系統壓力下降，轉向缸及馬達的運動不平穩，致使轉轉向遲緩無力，甚至無法轉向。油管接頭配合不當、密封不良及管路破裂；密封件配合不當、磨損、老化或損壞；油溫過高，從而增加泄漏。當發現外部漏油時，應及時進行維修。   
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量將直接影響轉向系統的工作狀態。液壓油過少，會使液壓泵因供油不足而導致機器的轉向動作遲緩，故應將液壓油添加至規定的液面；當液壓油不干凈或油箱內有異物時，雜質進入液壓系統后會造成密封件損壞或使元件配合副損傷，使內泄漏增加，從而引起轉向遲緩。為此，須對液壓油的油質進行認真的檢查。
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入了升降貨梯http://www.weheartgrub.com/液壓系統，也會對系統產生較大的影響，使轉向缸出現爬行，降低液壓系統的效率，從而引起轉向遲緩?？諝膺M入液壓系統的途徑有：轉向泵吸油管的接頭出松弛或油管破裂；轉向泵密封不良；油箱內的油面過低，使吸油管或回油管露出液面；液壓油油質不佳。如果轉向泵內漏嚴重，也可造成大連移動式升降平臺轉向遲緩。引起轉向泵內泄漏的一個重要原因是，泵的轉子和葉片的側面與側板端面之間的間隙過大。
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.
