液压升降平台http://www.rgsjpt.com/的泵轮由发动机驱动旋转，推动液体随泵轮一起绕其轴线旋转， 使其获得一定的速度和压力，其速度决定于泵轮的半径和转速。液压油靠动能冲向涡轮，作用于叶片一个推力，推动涡轮一起旋转，涡轮获得一定转矩，少部分液体动能在高速流动中与流道摩擦生热被消耗。导轮固定，液体流经时无机械能转化，由于导轮叶片形态变化(进出口叶片面积不等、液流速度和方向发生变化，其动量矩改变。动量矩变化取决于叶片面积的变化。 涡轮转速随外界负荷的不同而变化，液流冲击叶片的方向和速度亦随之变化。以上就是升降机上升运动的过程。
Jinan hydraulic lift pump wheel rotated by the engine, push the liquid along with the pump wheel about its axis of rotation, so get some speed and pressure, and the speed depends on the radius and speed of the pump wheel. By momentum toward the turbine hydraulic oil, a force acting on the blades, the turbines rotate together, get some turbo torque, a small part of the liquid flow at high kinetic energy is consumed with the flow channel friction and heat. Guide wheel fixed, no mechanical energy into the liquid flows through, because the morphological changes of the stator blades (leaf area ranging import and export, flow speed and direction changes, its moment of momentum change. Moment of momentum change depending on changes in leaf area. Turbine speed varies with the external load varies, the direction and speed of flow also changes the impact of the blade. above is lift upward motion process.
