液壓貨梯http://www.qdysj.net/是用液壓缸或鏈條驅(qū)動升降的機械設(shè)備，主要用于高空作業(yè)及高空維修。下面石家莊悅翔機械制造的專家給大家詳細分析一下液壓貨梯壓力維持措施有哪些？

1、利用特殊補償電路
當液壓貨梯位置或壓力下降到一定程度，自動啟動補償系統(tǒng)的作用時，液壓貨梯回到指定的位置。液壓貨梯設(shè)計補償系統(tǒng)時，以確保準確性，試驗壓力，此外還要考慮補償系統(tǒng)壓力，補償系統(tǒng)壓力必須大于系統(tǒng)壓力，否則為將發(fā)揮的作用與此相反。
When the position or pressure drop to a certain degree, the automatic start compensation system, the hydraulic cargo ladder back to the designated position. Hydraulic cargo ladder design compensation system, to ensure the accuracy of the test pressure, in addition to consider the compensation system pressure, compensation system pressure must be greater than the system pressure, or to play the role of the contrary. 

2、液壓換向閥型液壓回路或單向液壓鎖
液壓貨梯http://www.qdysj.net/液壓閥的壓力效應(yīng)，液壓鎖系列單向效果更好，比系列O型液壓的壓力，但壓力效應(yīng)是仍然有限，目前只使用對于定位精度不高的地方。
The pressure effect of hydraulic valve hydraulic elevator, hydraulic lock series of one-way effect is better than the series O type hydraulic pressure, but the pressure effect is still limited, currently used only for the positioning precision of the place.
