液壓升降機(jī)是通過(guò)電機(jī)驅(qū)動(dòng)液壓泵將液壓油通過(guò)閥塊、油管進(jìn)入油缸，由油缸帶動(dòng)支桿或者鏈條、鋼絲繩使工作臺(tái)面做工作順序。
Hydraulic lift is motor-driven hydraulic pump through the hydraulic oil through the valve block, tubing into the cylinder, the cylinder rod or chain drive, rope making countertops do the work order.

由于液壓油本身的壓縮比，液壓元件的內(nèi)泄漏，設(shè)備本身的升降間隙，當(dāng)荷載作用在工作臺(tái)面上時(shí)有一定的下沉量，當(dāng)工作環(huán)境要求嚴(yán)格，要求工作臺(tái)面在預(yù)定位置保持一定精度時(shí)，必須采取一定的措施：
Since the compression ratio of hydraulic oil itself, internal leakage of hydraulic components, the gap lifting device itself, when the load when a certain amount of subsidence in the work surface when the work environment is demanding accuracy requirements of the work surface at a predetermined position to maintain a certain , you must take certain measures:

1.提高液壓元件的精度、在液壓系統(tǒng)中設(shè)置液壓鎖、設(shè)置儲(chǔ)能器進(jìn)行液壓補(bǔ)償。
1 to improve the accuracy of hydraulic components, hydraulic lock set, setting the hydraulic accumulator be compensated in the hydraulic system.

2.設(shè)置特種導(dǎo)軌進(jìn)行機(jī)械鎖緊。
2 set of special rail mechanical lock.
