防止升降货梯转向迟缓有什么方法？

升降货梯在行驶中急转弯时常出现前轮转向迟缓的故障现象，根据转向系统的工作原理，可判定此故障是由于液压转向系统的容积效率下降和系统压力过低而引起的。下面济南天锐升降机械的技术人员给大家介绍如何防止这类事件的发生。

1、检查升降货梯http://www.jntr168.com/液压转向系统的外部是否有渗漏，说明有外部漏油，主要表现为液压油损失较大，系统压力下降，转向缸及马达的运动不平稳，致使转转向迟缓无力，甚至无法转向。油管接头配合不当、密封不良及管路破裂；密封件配合不当、磨损、老化或损坏；油温过高，从而增加泄漏。当发现外部漏油时，应及时进行维修。   
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、升降货梯液压油的质量将直接影响转向系统的工作状态。液压油过少，会使液压泵因供油不足而导致机器的转向动作迟缓，故应将液压油添加至规定的液面；当液压油不干净或油箱内有异物时，杂质进入液压系统后会造成密封件损坏或使元件配合副损伤，使内泄漏增加，从而引起转向迟缓。为此，须对液压油的油质进行认真的检查。
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、即使是少量的空气进入了升降货梯http://www.jntr168.com/液压系统，也会对系统产生较大的影响，使转向缸出现爬行，降低液压系统的效率，从而引起转向迟缓。空气进入液压系统的途径有：转向泵吸油管的接头出松弛或油管破裂；转向泵密封不良；油箱内的油面过低，使吸油管或回油管露出液面；液压油油质不佳。如果转向泵内漏严重，也可造成大连移动式升降平台转向迟缓。引起转向泵内泄漏的一个重要原因是，泵的转子和叶片的侧面与侧板端面之间的间隙过大。
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.
