Description

Punching stainless steel vortex pump Technical Field The utility model relates to the field of vortex pumps, in particular to a stamping stainless steel vortex pump. Background The working principle of the vortex pump is based on centrifugal force and vortex motion generated when the impeller rotates. The impeller is provided with a plurality of radially arranged blades, and when the impeller rotates in the pump shell, the blades push the liquid to rotate, so that the liquid obtains centrifugal force. A high-speed rotating liquid ring, called a vortex, is formed around the impeller. Because of the clearance between the impeller and the pump shell, the liquid moves spirally in the annular space between the impeller and the pump shell under the action of the vortex, and meanwhile, the liquid is sucked from the suction inlet and flows towards the discharge outlet under the pushing of the blades. The vortex pump mainly comprises a motor, a pump body, an impeller and a support, wherein the support is positioned between the motor and the pump body and is connected with the motor and the pump body, the impeller is arranged in the pump body, the pump body and the support of the vortex pump at present are molded in a traditional casting mode, the whole weight of a casting is heavy, the surface of the casting is rough, the hydraulic efficiency is low, and the improvement of the performance efficiency of a product is not facilitated.
