[0002] The axial clearance of the vortex pump is an important assembly dimension, which has a great influence on its hydraulic performance; when the vortex pump is working under low head conditions, the excessive axial clearance will cause excessive leakage in the vortex pump and increase the loss of leakage flow. Therefore, the efficiency is reduced; when the vortex pump is working under high lift conditions, the axial clearance is too small to cause greater friction between the impeller and the pump cover, and the energy generated by the work of the impeller is lost; the traditional method of adjusting the axial clearance Rely on workers' assembly experience, poor assembly accuracy and repeatability

Embodiment Construction
[0016] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.
[0017] Such as Figure 1 to Figure 3 As shown, a vortex pump with a floating side plate includes a pump cover 1, a pump body 2, an impeller 3, a floating side plate 4, and a compression spring 5. The floating side plate 4 has two pieces, and the axial position is the same as that of the impeller 3 Adjacent and symmetrically arranged on both sides of the impeller.
[0018] The floating side plate 4 is cylindrical with a through hole in the center, one side is a pressure plane 41, the edge is provided with a high-pressure water tank 42, and the other side is provided with a number of spring fixing ...

The invention discloses a vortex pump with floating side plates. The vortex pump comprises a pump cover, a pump body, an impeller, the two floating side plates and compression springs. The axial position of the floating side plates is adjacent to the impeller, and the floating side plates are symmetrically arranged at both sides of the impeller. The floating side plates are in a cylindrical shapewith through holes at the centers, one side of each floating side plate is a pressure plane, a high pressure water groove is formed in the edge of each floating side plate, and a plurality of spring fixing grooves are formed in the other side of each floating side plate. The high pressure water groove are circular chamfers with a certain arc along the edges of the pressure planes, the depth is determined according to the actual required opening pressure, and the circumferential direction does not coincide with the baffle tongue wrap angle portions of the pump cover and the pump body. The number of the compression springs is the same with the number of the spring fixing grooves, one ends of the compression springs are fixed to fixing holes of the pump cover or the pump body, and the other ends of the compression springs are in contact with the spring fixing grooves to ensure that the compression springs is horizontal in the working process. The vortex pump can automatically adjust the axial gap according to the working state of the vortex pump, so that the vortex pump always works under the optimal hydraulic performance condition.
Description
technical field [0001] The invention relates to a vortex pump, in particular to a vortex pump with a floating side plate, which belongs to the field of fluid machinery. Background technique [0002] The axial clearance of the vortex pump is an important assembly dimension, which has a great influence on its hydraulic performance; when the vortex pump is working under low head conditions, the excessive axial clearance will cause excessive leakage in the vortex pump and increase the loss of leakage flow. Therefore, the efficiency is reduced; when the vortex pump is working under high lift conditions, the axial clearance is too small to cause greater friction between the impeller and the pump cover, and the energy generated by the work of the impeller is lost; the traditional method of adjusting the axial clearance Relying on workers' assembly experience, the assembly accuracy and repeatability are poor.
