Centrifugal pump is the most common type of pump, which is mainly composed of eight parts: impeller, pump body, pump cover, water blocking ring, pump shaft, bearings, sealing ring, and packing box. When the prime mover drives the pump shaft and impeller to rotate at high speed, the liquid moves in a circular motion with the impeller on one hand, and is thrown out from the center of the impeller outward under the action of centrifugal force on the other hand. The liquid obtains pressure energy and velocity energy from the impeller. When the liquid flows through the vortex shell to the discharge port, some of the velocity energy will be converted into static pressure energy. When the liquid is thrown out of the impeller, a low-pressure area is created in the center of the impeller, which forms a pressure difference with the pressure of the suction liquid surface. As a result, the liquid is continuously sucked in and discharged at a certain pressure. So constantly circulating, the liquid is sent to another place.
Centrifugalne pumpe su zapravo a vrlo složeno tip pumpe sa širokim raznolikim modelima. Neka 's uzme a pogledaj kako centrifugalne pumpe su klasificirane.
(1) centrifugalne pumpe su podijeljene u jednostupanjske centrifugalne pumpe i višestupanjske centrifugalne pumpe prema broju rotora.
(2) Prema usisno metodi rotora, it može biti podijeljeno na jednostruko usisno centrifugalno pumpe i dvostruko usisno centrifugalno pumpe.
(3) Prema položaju pumpi osovini, it može biti podijeljeno u vodoravno pumpe (instalirano vodoravno) i okomito pumpe (instalirano okomito).
(4) Prema tipu pumpi kućištu, it može biti podijeljeno na segmentirano centrifugalno pumpe i vodoravno otvoreno centrifugalno pumpe.
(5) Prema transportu mediju% 2c it je podijeljeno u vodu pumpe (transport voda)% 2c ulje pumpe (transport ulje proizvodi)% 2c kemikalije pumpe (transport kiselina i alkalija ili ostalo kemijsko sirovine materijali)% 2c i bušenje pumpe (transport bušenje tekućina).
