導(dǎo)軌升降機http://www.ltjd.net.cn/液壓站的不保壓是系統(tǒng)常見的故障，液壓站啟動的情況下，是肯定有壓力的。下面濟南榮凱升降機械的專家給大家詳細分析一下導(dǎo)軌升降機液壓站不保壓是什么原因？

1、導(dǎo)軌升降機液壓站開啟的情況下，無壓力。主要原因是泵站損壞，泵壓力調(diào)的太低，減壓閥調(diào)壓力太低，總體來說是因為壓力直接泄到油箱了，建立不起壓力。
 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、如果導(dǎo)軌升降機液壓站關(guān)閉后，執(zhí)行機構(gòu)不保壓。主要原因是液壓系統(tǒng)無保壓回路，單向閥壞；如果有蓄能器，或許是因為蓄能器氣壓壓力不夠。
 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、如果導(dǎo)軌升降機http://www.ltjd.net.cn/聲音大，可能是柱塞泵要壞了，使用時間久了磨損嚴(yán)重了會有比較大的噪音；還有就是你的使用壓力可能超過柱塞泵本身的額定壓力了；蓄能器本身沒什么聲音，只有在泄壓時會有比較響的聲音。
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.
