进口立式污水泵Product Description: The sewage pump comprises a pump body with a pump cavity and a pump shaft with one end positioned in the pump body. The bottom of the pump body is provided with a water inlet, the water inlet has a straight cylindrical inner peripheral surface, the side of the pump body is provided with a water outlet, the inner end of the pump shaft is fixedly connected with an impeller, the bottom of the impeller has a straight cylindrical water absorption part, the water absorption part extends into the water inlet, and there is an assembly gap between the outer peripheral surface of the water absorption part and the inner peripheral surface of the water inlet, The outer peripheral surface of the water absorption part is provided with a leak proof thread along the axial direction. The leak proof thread is located in the assembly gap, and there is a gap between the tooth top of the leak proof thread and the inner peripheral surface of the water inlet. The leak proof thread rotates from the bottom to the top in the opposite direction to the rotation direction of the pump shaft.进口立式污水泵 The sewage pump has higher working efficiency. characteristic: The sewage pump is a kind of centrifugal pump, which is mainly used to transport urban sewage. Because the sewage contains granular impurities, fiber impurities, etc., the impeller and water pressure chamber are the two core components of the sewage pump. The performance of the impeller and water pressure chamber represents the performance of the pump. The anti blocking performance, efficiency and cavitation performance of the sewage pump are mainly guaranteed by the two components of the vane pump and water pressure chamber, The impeller of the sewage pump is located in the pump cavity. When rotating, it can discharge the sewage in the pump cavity from the side outlet. At the same time, the negative pressure in the pump cavity can suck the external sewage from the water inlet. Of course, if the water inlet is completely open, it will also lead to pressure leakage in the pump cavity and affect the working efficiency. Principle: The lower end of the pump body is fixedly connected with a base, the base is provided with a cylindrical part, the inner hole of the cylindrical part is the water inlet, the lower edge of the inner peripheral surface of the cylindrical part is provided with an anti blocking convex edge in the circumferential direction, the water absorption part is located above the anti blocking convex edge, the inner diameter of the anti blocking convex edge is less than the outer diameter of the water absorption part, and there is a gap between the lower end face of the water absorption part and the upper end face of the anti blocking convex edge. Because the leak proof thread can generate an upward thrust in the assembly gap, and the thrust becomes an inward suction at the lower end of the assembly gap. The suction is easy to suck granular impurities into the assembly gap, resulting in material jamming and affecting the rotation efficiency of the impeller. Therefore, an anti blocking convex edge is set at the lower end of the cylindrical part, which can cover the lower end of the assembly gap, so as to prevent granular impurities from being sucked into the assembly gap, There is still a gap between the upper end face of the anti blocking convex edge and the lower end face of the water absorption part, but the gap faces the inlet end of the water absorption part. Therefore, even if there are granular impurities attached to the gap between the anti blocking convex edge and the water absorption part under the suction of the leak proof thread, they will be sucked into the pump cavity by the large suction of the water absorption part, so as to prevent the granular impurities from entering or blocking the assembly gap, so that the leak proof thread can continuously generate upward thrust.
