液力偶合器是利用液体(矿物油)动能传递功率的一种动力式液力传动设备,一般由泵轮,涡轮和转动外壳等主要部件组成。泵轮和涡轮对称布置,轮内有很多径向辐射并与轴线平行的叶片。运转前,在偶合器中充以工作油。当输入轴带动泵轮旋转时,由于离心力的作用,工作油在叶片带动下从泵轮内侧流向外缘,形成高压高速油流并冲向涡轮叶片,使涡轮跟随泵轮同方向旋转,涡轮中工作油从外缘流向内侧,同时减压减速,然后再流入泵轮进口,如此循环不
Hydraulic coupling is the use of liquid (mineral oil) kinetic energy transfer power of a dynamic hydraulic transmission equipment, generally by the pump, turbine and rotating housing and other major components. The impeller and turbine are symmetrically arranged with many blades radiating radially and parallel to the axis. Before operation, fill the coupling with working oil. When the input shaft drives the pump wheel to rotate, due to the centrifugal force, the working oil flows from the inner side of the impeller to the outer edge to form a high-pressure high-speed oil flow and rushes toward the turbine blades to make the turbine rotate in the same direction with the pump impeller. Working oil flow from the outer edge to the inside, while decompression deceleration, and then flow into the pump inlet, so the cycle is not
