液压千斤顶

千斤顶是材料处理设备，使用强制乘法来抬起或移动重载。 The term jacks can refer to a variety of lifting devices that employ leverage and other methods of mechanical advantage to amplify an applied force to provide the ability to transport a load.Hydraulic jacks are distinguished by their use of an in-compressible liquid, such as hydraulic fluid or jack oil, as the means by which force multiplication is achieved.It creates pressure by moving oil through two cylinders via a pump plunger. 将泵柱塞拉回，从而打开吸气阀并将油吸入泵室。 当柱塞向下推时，将油通过外部排放阀运输到气缸腔中。 然后关闭吸气阀，导致腔室内的压力增加； 使腔室中的活塞升起并抬起重物。 可以多次重复此过程，从而使您的负载更高，更高。
