However, if the umbrella rotation speed, the friction enough to make water droplets in a circular motion, then drop the sport from the umbrella to the outer edge, like a rope pulling the stones to do with circular motion, if the speed is too fast, the rope will disconnect, stones will be flying out. This is the so-called centrifugal. 矚慫润厲钐瘗睞枥庑赖。Centrifugal pump is designed according to this theory, high-speed rotation of the impeller blades rotate driven water, throw water, so as to achieve the purpose of transportation. 聞創沟燴鐺險爱氇谴净。Good variety of centrifugal pumps, from the use can be divided into civil and industrial pumps; from the transmission medium can be divided into clear water pump, trash pump, corrosion pump and so on.残骛楼諍锩瀨濟溆塹籟。Basic structure centrifugal pumpBasic structure of the centrifugal pump is composed of six parts, namely: impeller, shaft, bearings, seal rings, stuffing box.酽锕极額閉镇桧猪訣锥。1 centrifugal impeller is a core component of its speed and high output force, the impeller blade has played a major role in the assembly before the impeller by static test. Impeller on the inside and outside surfaces required to be smooth to reduce flow friction loss.彈贸摄尔霁毙攬砖卤庑。2, pump, also known...
