wwwju11举升速度不稳定从现场使用来看,经常出现升降抖动、上升位置较难检测找不到中位、上升时有冲击噪声、液压缸渗油等现象.Chengdu lifting platform lifting speed is not stable from the use of the field of view, often rise and rise jitter, rising position is difficult to detect can not find the middle position, the rise of impact noise, hydraulic cylinder oil leakage and other phenomena.

1.经现场察看主要是成都升降液压缸的举升速度过快,致使故障率增加,严重影响了生产效率.升降液压缸举升速度不稳定的原因分析液压缸举升速度不稳定,其原因很多,有设计方面的、也有加工制造和使用方面的。The scene view is mainly Chengdu lifting hydraulic cylinder lifting speed too fast, resulting in the increase of failure rate, seriously affecting the efficiency of production. The reason of lifting speed lifting hydraulic cylinder stability analysis of hydraulic cylinder lifting speed is not stable, for many reasons, there are design, there are aspects of manufacture and use.

 

2.针对该液压系统存在的故障,运用速度刚度理论,分析升降液压缸举升速度不稳定的原因。According to the faults of the hydraulic system, using the theory of velocity stiffness, the reasons for the instability of the lifting speed of the hydraulic cylinder are analyzed.

3.当负载不变时,节流阀口进越小,则系统速度刚度进越高;反之,若节流阀开口面积越大,则进越低.When the load is constant, the throttle orifice into the smaller, the system speed stiffness into the higher; otherwise, if the throttle valve opening area, the lower the inlet.

4.当负载不变时,低速下的速度刚度好,当负载变化时,负载小时的速度刚度好.When the load is constant, the speed of the low speed is good. When the load changes, the speed of the load hour is good.

5.提高供油压力加大液压缸有效作用面积,可提高速度刚度.Increase the supply pressure to increase the effective area of the hydraulic cylinder, can improve the speed stiffness.

综上所述,引发wwwju11该故障的主要原因是液压系统提升调速回路设计不合理造成.In summary, the main reason for the failure of the Chengdu lift platform is the hydraulic system to upgrade the speed loop design is not reasonable.
