Centrifugal pump works by the impeller is constantly rotating and centrifugal motion of water to work. Before starting the pump, the pump housing and suction pipe must be filled with water before the motor can be started, so that the pump shaft drives the impeller and water to rotate at a high speed. The water is centrifuged and is thrown to the outer edge of the impeller. Of the flow into the pump pressure water pipe. Because of its large variety, then introduced by several aspects of centrifugal pump type. Centrifugal pump 1, according to the method of liquid inhalation impeller: Centrifugal pump classification (1) single-suction centrifugal pump: only one side of the impeller suction port, liquid from the impeller side into the impeller. (2) Double Suction Centrifugal Pump: Both sides of the impeller have suction ports, and the liquid enters the impeller from both sides. 2, according to the impeller series: (1) single-stage pump: only one impeller. (2) Multistage Pump: Two or more impellers mounted in series on the same pump shaft. 3, divided by the pump body: (1) Volute pump: shell helical shape, the liquid thrown from the impeller, into the spiral chamber, and then into the discharge line, such as the Y-pump. (2) double volute pump: impeller discharge side of the shell with double scroll chamber. (3) cartridge pump: the pump inner shell mounted in an outer cylinder double shell centrifugal pump. 4, according to the pump can be divided into different media: water pumps, sewage pumps, corrosion-resistant pumps, chemical pumps and so on. In summary, we can understand that a large number of centrifugal pumps, the applicable point is different. For consumers, to grasp a certain product type to distinguish knowledge is very important for product selection and use. With the continuous development of vacuum pump business in our country, the challenges facing centrifugal pumps are also constantly expanding. How to maintain its competitiveness requires the joint efforts of all circles. Related Articles: Vacuum pump type classification and types Daquan Water ring vacuum pump type and model Daquan
