Abstract
The utility model relates to a centrifugal water pump with double impeller bases, which is mainly used for delivery in the chemical engineering industry and irrigation and drainage in the field of farmland. The centrifugal water pump adopts the structure that the right end of the impeller is lengthened on the basis of the prior centrifugal water pump, a bearing is additionally arranged inside the pump wall at the water inlet at the right end of the pump body, and the excircle of the lengthened part of the right end of the impeller is supported inside the additionally arranged bearing. The centrifugal water pump has the advantages of stable operation, low kinetic loss, good sealing effect, low water flow loss, relatively high delivery lift and long service life.
Description
Technical field
The utility model relates to a kind of centrifugal water pump of drawing liquid body medium, is mainly used in dispatch in the chemical industry and the irrigation and drainage in the field, farmland.
Technical background
Impeller in the at present existing centrifugal water pump is to be fixed on the termination of main shaft, is in cantilever position.So produce bigger degree of disturbing during its work running, Sealing easy and that the pump housing is interior produces friction or collision, and it causes bigger power loss for a moment like this; Its two sealing that can destroy the pump housing causes the current loss to cause pump efficiency to descend, and the lift of water pump is reduced greatly; It three can make the operating life of water pump significantly reduce.Therefore must carry out necessary improvement to the cantilever structure design of impeller in the existing centrifugal water pump.
Summary of the invention
The purpose of this utility model is to avoid deficiency of the prior art, provide a kind of impeller work running steadily, little, the good sealing effect of kinetic equation loss, the current loss is low, lift is high relatively, the impeller dual-supporting centrifugal water pump of long working life.
The purpose of this utility model adopts following technical measures to realize: this impeller dual-supporting centrifugal pump is to improve to form on the basis of existing centrifugal water pump, and it also includes coupling, the pump housing, pump seat, pump cover, main shaft, bearing, seal ring and impeller.Its innovation part is the newly-increased bearing A that is provided with in the pump housing wall of pump housing right-hand member water inlet, and the right-hand member with impeller increases simultaneously, and the cylindrical that allows impeller increase right-hand member is bearing in the bearing A that newly establishes.
The beneficial effects of the utility model are that the impeller operation of this impeller dual-supporting centrifugal water pump is steady, make the kinetic equation loss of water pump little, good sealing effect, and the current loss is little, and lift increases, and prolong working life.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Among the figure: 1 coupling, 2 keys, 3 main shafts, 4 seal rings, 5 pump seats, 6 pump housings, 7 bearing A, 8 seal ring B, 9 back-up rings, 10 impellers, 11 pump covers, 12 key C13 bearings
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: this impeller dual-supporting centrifugal water pump is to improve to form on the basis of existing centrifugal water pump.It includes coupling 1, the pump housing 6, pump seat 5, pump cover 11, main shaft 3, bearing 13, seal ring 4 and impeller 10.Just the right-hand member with impeller 10 increases, and increases newly in the pump housing wall of the pump housing 6 right-hand member water inlets simultaneously and is provided with bearing A7, and allow the cylindrical of impeller 10 right-hand member incremental portions be bearing in this bearing A7.Also be provided with seal ring B8 in addition, with back-up ring 9 seal ring B8 pushed down simultaneously on the left and right both sides of bearing A7.Impeller 10 is to be connected with main shaft 3 right-hand members by key C12.Coupling 1 is to be connected with main shaft 3 left ends by key 2.
Claims (1)
