提高液压货梯http://www.jnliqiao.com/齿轮泵压力必须减小端面轴向间隙泄漏，一般采用齿轮端面间隙自动补偿的办法来解决这个问题。
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.

液压货梯http://www.jnliqiao.com/齿轮端面间隙自动补偿原理是利用特制的通道，把泵内压油腔的压力油引到浮动轴套外侧，作用在一定形状和大小的面积上，产生液压作用力，使轴套压向齿轮端面的液压力大小必须保证浮动轴套始终紧贴齿轮端面，减小端面轴向间隙泄漏，达到提高工作压力的目的，液压货梯浮动轴套型和浮动侧板型高压齿轮泵就是根据上述原理设计制造的。
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.
