导轨升降机http://www.rongkaijx.com/液压站的不保压是系统常见的故障，液压站启动的情况下，是肯定有压力的。下面济南荣凯升降机械的专家给大家详细分析一下导轨升降机液压站不保压是什么原因？
1、导轨升降机液压站开启的情况下，无压力。主要原因是泵站损坏，泵压力调的太低，减压阀调压力太低，总体来说是因为压力直接泄到油箱了，建立不起压力。
Under the condition of the hydraulic station of the guide rail lift, no pressure. The main reason is the pump damage, pump pressure is too low, pressure relief valve adjustment is too low, in general, because the pressure is directly discharged into the tank, the pressure can not be established.
2、如果导轨升降机液压站关闭后，执行机构不保压。主要原因是液压系统无保压回路，单向阀坏；如果有蓄能器，或许是因为蓄能器气压压力不够。
If the guide rail lift hydraulic station closed, the actuator does not keep pressure. The main reason is that the hydraulic system without the protection of the pressure circuit, one-way valve is bad; if there is a storage device, perhaps because the accumulator pressure is not enough pressure.
3、如果导轨升降机http://www.rongkaijx.com/声音大，可能是柱塞泵要坏了，使用时间久了磨损严重了会有比较大的噪音；还有就是你的使用压力可能超过柱塞泵本身的额定压力了；蓄能器本身没什么声音，只有在泄压时会有比较响的声音。
If elevator guide rails sound may be plunger pump will go bad, is used for a long time wear serious will have relatively large noise; there is pressure you use may more than the rated pressure piston pump itself; storage is no sound,only in the relief will be quite loud voice.
