With the increasing use of multi-stage pump to understand its working principle and structure of the product for the use and innovation is extremely important. Next mainly introduces the working principle of multistage pump. Multi-stage pump in the multi-stage pump work, the pump body into a certain amount of water as a working fluid. When the impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the lower part of the water ring just tangential to the impeller hub, the upper surface of the water ring three self-balancing multi-stage pump three self-balancing multi-stage pump just in contact with the blade tip (in fact the blade has a certain amount of water ring Insert depth). At this moment, a crescent-shaped space is formed between the impeller hub and the water ring, and the space is divided into a plurality of small cavities equal to the number of the blades by the impeller. If the lower part of the impeller 0 ° as a starting point, then the impeller 180 ° before the rotation of the small chamber volume from small to large, and the end of the suction port communicating, when the gas is inhaled, when the inhalation end of the small cavity When the impeller continues to rotate, the small cavity becomes smaller and the gas is compressed; when the small chamber communicates with the exhaust port, the gas is discharged outside the pump. From the above introduction we can analyze, multi-stage pump is to change the volume to work, so it is a variable volume centrifugal pump. Multistage pumps can be used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine and foodstuffs. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing, multistage pumps are widely used. Can be evacuated flammable, explosive gas, in addition to pumping dust, water-containing gas, therefore, water ring pump applications are increasing. Multistage pump is a centrifugal pump.
