Improve the hydraulic gear pump pressure must be reduced freight elevators end face axial clearance leakage, generally use the gear end clearance automatic compensation of ways to solve this problem.

液壓貨梯http://www.lxoz.cn/齒輪端面間隙自動補償原理是利用特制的通道，把泵內(nèi)壓油腔的壓力油引到浮動軸套外側(cè)，作用在一定形狀和大小的面積上，產(chǎn)生液壓作用力，使軸套壓向齒輪端面的液壓力大小必須保證浮動軸套始終緊貼齒輪端面，減小端面軸向間隙泄漏，達到提高工作壓力的目的，液壓貨梯浮動軸套型和浮動側(cè)板型高壓齒輪泵就是根據(jù)上述原理設計制造的。
Hydraulic freight elevator gear end clearance automatic compensation principle is to use a special channel, the pressure within the pumping chamber to the outside pressure oil floating sleeve lead role in a certain shape and size of the area, resulting in a hydraulic force, the pressure to make the sleeve hydraulic pressure must ensure that the size of the gear end float is always close to the gear end bushings, reducing leakage end face axial clearance, the purpose to improve the working pressure, hydraulic freight elevators and floating side floating sleeve-type high-pressure gear pump is based on the principle design and manufacture.
