Description
Technical Field
The utility model relates to a field of centrifugal pump, concretely relates to centrifugal pump structure is used to swimming pool, hydrotherapy, hot water bath and other recreational water facilities.
Background
The centrifugal pump is a pump for conveying a liquid by centrifugal force generated when an impeller rotates. At present, a pump body volute of the existing swimming pool pump product in the market is an annular extrusion chamber, a diffusion guide vane structure is added between an impeller and the pump body extrusion chamber for transition, the diffusion guide vane is extruded and fixed by a pump body and a cover plate through transition fit, the diffusion guide vane is not separately positioned, the equipment stability is not high due to the influence of processing and assembling precision; the inlet assembly and the outlet assembly of the existing swimming pool pump are connected by pipe threads, the pipe threads do not have self-sealing effect, and a complex sealing structure needs to be designed independently; the conventional swimming pool pump is provided with a conventional single-phase or three-phase motor, the noise value is high during operation, and the user experience is general.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art, and provides a centrifugal pump structure for swimming pools, hydrotherapy, hot water baths and other water facilities for entertainment, which has the advantages of simple and compact structure, strong reliability and low use noise.
The purpose of the utility model is accomplished through following technical scheme: the centrifugal pump structure for swimming pools, hydrotherapy, hot water baths and other recreational water facilities comprises a pump body, wherein a water inlet and a water outlet are formed in the pump body; the bottom of the motor is fixedly connected with the bottom of the pump body through a bottom plate component.
As a further technical scheme, a filter assembly is arranged in the pump body close to the water inlet.
As a further technical scheme, the motor adopts a low-noise motor.
As a further technical scheme, NPT taper pipe threads are adopted at the connection parts of the inlet assembly and the outlet assembly and the pump body.
The utility model has the advantages that:
1. the diffusion guide vane is fixed on the pump body through a positioning screw, so that the diffusion guide vane is completely fixed, the operation is stable, and the reliability is higher;
