(A) CYZ self-priming centrifugal pump basic structure CYZ self-priming centrifugal pump is the basic components of high-speed rotating impeller and a fixed snail-shaped pump shell. Impellers with several (usually 4 to 12) backswept blades are fastened to the pump shaft and rotated by the motor at high speed with the pump shaft. The impeller is a component that directly works on the liquid in the pump and is a power supply device for the CYZ-type self-priming centrifugal pump. The suction port in the center of the pump housing is connected to the suction line, and the bottom of the suction line is fitted with a one-way bottom valve. The discharge port on the side of the pump housing is connected to the discharge line fitted with a regulating valve. (B) CYZ-type self-priming centrifugal pump works When the CYZ self-priming centrifugal pump starts, the pump shaft driven impeller together for high-speed rotation movement, forcing pre-filling in the liquid between the blades of rotation, under the action of inertial centrifugal force , The liquid moves radially from the impeller center to the outer periphery. Liquid flows through the impeller in the process of gaining energy, static pressure can increase the flow rate increases. When the liquid leaves the impeller and enters the pump casing, it will decelerate due to the gradual enlargement of the flow passage in the shell. Some of the kinetic energy will be converted into static pressure energy and flow into the discharge pipe in the tangential direction finally. Therefore, the snail-shaped pump housing is not only a collection of components from the impeller out of the liquid, but also a transformable device. When the liquid thrown from the center of the impeller to the periphery at the same time, the center of the impeller to form a low pressure zone, the tank surface and the impeller center of the total potential difference under the action of the liquid was sucked into the impeller center. Depending on the continuous operation of the impeller, the liquid is continuously aspirated and discharged. The mechanical energy obtained by the liquid in the CYZ self-priming centrifugal pump ultimately shows an increase in static pressure energy.
