Abstract
The utility model aims to solve the problems that the axial distance of impeller cannot be adjusted in the prior art and the centers of an impeller outlet and a pump shell are not centered due to the accumulation of mechanical processing dimension error, and provides a positioning structure of a double suction pump impeller, wherein the positioning structure is characteristic in that the axial position of the impeller can be adjusted within a certain range, and meanwhile, the impeller can be positioned firmly. The positioning structure comprises the double suction pump impeller and a shaft of the double suction pump and is characterized in that threads are processed at the two ends of the positioning part of the impeller on the shaft of the double suction pump; the threads at the two ends are respectively provided with a double round nut; and the impeller is fixed on the double round nuts at the two ends. The positioning structure has the advantages that the axial position of the impeller can be adjusted within a certain range, the condition that the centers of the impeller outlet and the pump shell are centered is realized; and meanwhile, the double round nuts can be positioned firmly and can be interlocked, so that loosing phenomenon cannot occur, the hydraulic efficiency of the double suction pump is ensured and the stable operation of the double suction pump is ensured.
Description
Technical field
The utility model relates to a kind of position structure of new type double sucking pump impeller.
Background technique
At present, great majority all are to adopt circlip for shaft 12 to realize the (see figure 1) of locating between the impeller 11 of double suction pump and the axle 13, and this orientation type is simple, convenient; But axial position can't be adjusted after the location; Because machining accuracy can't guarantee that sometimes the accumulation of size error causes impeller outlet center and pump case center to misalign through regular meeting; Can have a strong impact on the hydraulic efficiency of double suction pump like this, influence the use of water pump.
Summary of the invention
The purpose of the utility model is that impeller shaft can't be adjusted to distance in the solution existing technology; The problem that misaligns because of the accumulation of machining dimension error existing impeller outlet center and pump case center; A kind of axial position that can regulate impeller within the specific limits is provided, and the while is the position structure of the double suction pump impeller of firm position again.The utility model designs a kind of position structure of new type double sucking pump impeller; Comprise double suction pump impeller, axle; It is characterized in that: the two ends at the place, impeller location on the axle of double suction pump are processed with screw thread, and two round nuts are respectively arranged on the screw thread at two ends, and two round nuts at two ends are impeller fixedly.The utility model has the advantages that the axial position that not only can regulate impeller within the specific limits; Realize impeller outlet center and pump case center; Simultaneously two round nut firm positions are realized interlocking, and loosening phenomenon can not take place; Both guaranteed the hydraulic efficiency of double suction pump, the smooth running of the double suction pump that guarantees again.
Description of drawings
Fig. 1 is the prior art constructions sectional drawing.
Fig. 2 is the section of structure of the utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise double suction pump impeller 1, axle 2, round nut 3 among Fig. 2.The two ends machining screw 4 at the impeller location place on the axle of double suction pump penetrates axle with impeller earlier during assembling, and round nut is screwed to that axle is gone up but not locked; After installing other component whole rotor is put on the pump case; At this moment just can regulate the axial position of impeller, after impeller outlet center and pump case center, earlier first round nut at impeller two ends locked through twisting round nut; Realize the fixing of impeller; And then second round nut and first round nut at two ends is locked, both realized impeller outlet center and pump case center, make that again the location is more firm.
