离心泵

　　离心其实是物体惯性的表现.比如雨伞上的水滴,当雨伞缓慢转动时,水滴会跟随雨伞转动,这是因为雨伞与水滴的摩擦力做为给水滴的向心力使然.但是如果雨伞转动加快,这个摩擦力不足以使水滴在做圆周运动,那么水滴将脱离雨伞向外缘运动.就象用一根绳子拉着石块做圆周运动,如果速度太快,绳子将会断开,石块将会飞出.这个就是所谓的离心.
　　Centrifugal inertia is the performance of an object. Such as umbrellas on the water droplets, when the umbrella slowly rotating, the water droplets will follow the umbrella rotation, because the umbrella of the friction with the water droplets to drop as the centripetal force of Shiran. But if an umbrella rotation speed, the friction is not enough to drop in a circular motion, then the drop will be from the outside edge of an umbrella campaign. like a rope pulling the stones to do with circular motion, if the speed is too fast, the rope will break, stones will be fly. This is the so-called centrifugal.

　　离心泵就是根据这个原理设计的.高速旋转的叶轮叶片带动水转动,将水甩出,从而达到输送的目的.
　　 Centrifugal pump is based on this principle of design. High-speed rotation of the impeller blades driven water, turning water thrown, so as to achieve the purpose of transportation.
