Description
Technical Field
The utility model belongs to the technical field of extracting tool, concretely relates to supporting dismounting device of multistage pump impeller.
Background
The multistage pump is widely applied to the fields of industrial and urban water supply and drainage, sewage treatment, petrochemical industry, ship industry, high-rise building pressurization water supply, fire control pressurization, remote water supply, heating, bathrooms, boiler cold and hot water circulation pressurization, air-conditioning and refrigerating system water supply and equipment matching, wastewater purification and the like.
The multistage centrifugal pump has many kinds, but the working principle is the same, and the structure is the same. The main components are a rotating impeller and a stationary pump casing. The impeller is a part which directly does work on the liquid, and belongs to a key and easily-damaged part of a multi-stage pump. The multistage pump impeller has higher precision requirement in installation and puts very high requirements on the disassembly process. During the disassembly process, the impeller is ensured to be protectively withdrawn from the shaft, so that the phenomenon that the impeller and the shaft are pulled or even are seized is avoided.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art and not enough, the utility model provides a supporting dismounting device of multistage pump impeller.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a supporting dismounting device of multistage pump impeller, includes impeller connection lead screw, unable adjustment base plate and jackscrew, unable adjustment base plate be the rectangle structure and make by the steel sheet, jackscrew and impeller connection lead screw have the screwed one end and all pass and extend behind the unable adjustment base plate, the extension section and the multistage pump shaft threaded connection of jackscrew, the impeller connection lead screw extend section and the epaxial hole threaded connection of multistage pump impeller, the axle end face of unable adjustment base plate terminal surface and multistage pump shaft is parallel, and when towards the multistage pump shaft counter-rotation jackscrew, the impeller connection lead screw drives multistage pump impeller landing from the axle.
Furthermore, the jackscrew is located the central point of fixed base plate and put, the impeller connects the lead screw and is a set of to be the central point central symmetry distribution of fixed base plate.
Further, the rod cap of the jackscrew is an inner square or inner hexagonal nut.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a be connected impeller connection lead screw and multistage pump impeller screw, the adjustment position makes the parallel subsides of fixed baseplate end face and multistage pump shaft terminal surface tight, and rotatory jackscrew makes the impeller landing from the axle, dismantles all the other impellers at different levels in proper order, the utility model discloses simple structure, operation safety have realized that the impeller protectiveness demolishs.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the impeller is connected with a lead screw, 2, a fixed base plate, 3, a multi-stage pump impeller, 4, a jackscrew and 5, a multi-stage pump shaft.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a supporting dismounting device of multistage pump impeller, including impeller connection lead screw 1, unable adjustment base plate 2 and jackscrew 4, unable adjustment base plate 2 is the rectangle structure and is made by the steel sheet, jackscrew 4 and impeller connection lead screw 1 have the screwed one end all pass after unable adjustment base plate 2 and extend, the extension section and the multistage pump shaft 5 threaded connection of jackscrew 4, jackscrew 4 is located the central point of unable adjustment base plate 2, impeller connection lead screw 1 is a set of, and be the central point central symmetry distribution of unable adjustment base plate 2, the extension section of impeller connection lead screw 1 and the hole threaded connection on the multistage pump impeller 3, the end face of unable adjustment base plate 2 is parallel with the shaft end face of multistage pump shaft 5, when towards multistage pump shaft 5 opposite direction rotation jackscrew 4, impeller connection lead screw 1 drives multistage pump impeller 3 and from the epaxial landing.
The utility model discloses when specifically using, the impeller is connected lead screw 1 and is connected with the 3 screws of multistage pump impeller, and the adjustment position makes 2 terminal surfaces of fixed baseplate and 5 terminal surface parallel subsides of multistage pump shaft tightly, and rotatory jackscrew 4 makes multistage pump impeller 3 landing from multistage pump shaft 5, dismantles all the other multistage pump impellers 3 at different levels in proper order.
