立式离心泵工作原理
立式离心泵工作原理
Working Principle of Vertical Centrifugal Pump
立式离心泵是选用水泵的流量Q、扬程H、效率η、功率、转速n、工作压力、需要气蚀余量(NPSH)等作为主要控制参数。适合运输粘度小的清洁液体。按照工作叶轮数目可以分为单级泵和多级泵的立式离心泵。
Vertical centrifugal pump chooses flow Q, head H, efficiency_, power, rotating speed n, working pressure, need cavitation allowance (NPSH) as the main control parameters. Suitable for transporting clean liquids with low viscosity. According to the number of working impellers can be divided into single-stage pump and multi-stage pump vertical centrifugal pump.
立式离心泵主要是依靠旋转叶轮对液体进行作用把原动机的机械能传递给液体。因为它的作用使得液体在叶轮进口流向出口过程中，使液体速度能和压力能有所增加。当液体经过压出室时，大部分的速度能被转化为压力能，然后从排出管路被输送出去。这个时候，叶轮进口处因为液体的排出而产生真空或低压现象，在吸水池中液体在大气压的作用下，被输送到轮进口出，所以旋转的叶轮会形成一个循环，不断的吸入和排出液体。
Vertical centrifugal pump mainly relies on the rotating impeller to act on the liquid to transfer the mechanical energy of the prime mover to the liquid. Because of its function, the velocity energy and pressure energy of liquid increase in the process of flow from the impeller inlet to the impeller outlet. When the liquid passes through the extrusion chamber, most of the velocity can be converted into pressure energy, which is then transported out of the discharge pipeline. At this time, the impeller inlet due to the discharge of liquid produced a vacuum or low pressure phenomenon, in the suction tank under the action of atmospheric pressure, the liquid is transported to the wheel inlet, so the rotating impeller will form a cycle, continuous inhalation and discharge of liquid.
