Abstract
The utility model belongs to the technical field of swimming pool pump fittings, in particular to a sand-proof swimming pool pump impeller. An impeller cover is arranged above an impeller blade, a water inlet of the impeller cover has a hollow opening ring structure, and a plurality of grooves are uniformly distributed on the outer circumferential surface of the opening ring of the impeller cover. Through the serrated grooves, abrasion between solid granules and the opening ring of the impeller can be reduced, so that the performance of a water pump is ensured, and the service life of the water pump is prolonged; and the impeller is easy and convenient to use.
Description
Technical field:
The utility model belongs to swimming pool pump accessory technical field, refers in particular to a kind of sand prevention swimming pool pump impeller.
Background technique:
The impeller of swimming pool pump the inside installation generally is not with the sand prevention function at present, and after impeller was installed on the pump shaft, there was circular runout in its choma; Also there is circular runout in pump housing choma hole.One week of wheel rotation, can be when forwarding a certain angle to, the maximal clearance or the minimum clearance of choma radial clearance appears in the part.With this simultaneously, the pump shaft of rotation meeting bending deflection produces maximum deflection.After this circular runout and the maximum deflection stack, the radial clearance of choma just has local dynamic maximal clearance and minimum clearance.Cause the choma gap to increase after the impeller port ring long term wear, make pump performance descend.Simultaneously; Because regular meeting has solid particle or other ropies such as silt during the water in the swimming pool; After through swimming pool pump water inlet mouth; Probably longer in the impeller port ring place waiting time, the wearing and tearing aggravation of solid particle and impeller port ring makes the choma gap strengthen, and directly causes water pump the situation that performance reduces after having used a period of time, to occur.
Summary of the invention:
The purpose of the utility model provides a kind of performance that can well keep water pump, easy to use, simple sand prevention swimming pool pump impeller.
The utility model is achieved in that
A kind of sand prevention swimming pool pump impeller, the top of impeller blade is provided with impeller cover, and the water intake of impeller cover is the choma structure of hollow, circumferentially is evenly equipped with several grooves on the outer peripheral surface of the choma of described impeller cover.
Above-mentioned groove is jagged groove.
Above-mentioned groove has eight.
The utility model is compared the outstanding advantage of existing technology:
The jagged groove of the utility model can reduce the wearing and tearing between solid particle and the impeller port ring, has guaranteed the performance of water pump, has improved the working life of water pump, uses simple, convenient.
Description of drawings:
Fig. 1 is the schematic perspective view of the utility model;
Fig. 2 is the sectional view of the utility model;
Fig. 3 is the local enlarged diagram of the choma of the utility model.
Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1-3:
A kind of sand prevention swimming pool pump impeller, the top of impeller blade 1 is provided with impeller cover 2, and the water intake of impeller cover 2 is the choma structure of hollow, circumferentially is evenly equipped with several grooves 4 on the outer peripheral surface of the choma 3 of described impeller cover 2.
Above-mentioned groove 4 is jagged grooves.
Above-mentioned groove 4 has eight.
The foregoing description is merely one of preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; So: the equivalence that all shapes according to the utility model, structure, principle are done changes, and all should be covered by within the protection domain of the utility model.
