Abstract
The utility model discloses an easy disassembling and assembling centrifugal pump. An impeller (4) is arranged in a pump body (3) and the front part of the impeller (4) is respectively provided with a short axle sleeve (6), an axle sleeve (12) and a water throwing ring (14). The outer part of the axle sleeve (12) is provided with a sealing box body (8). The pump body on the front part is provided with a wear resisting board (5) which can be disassembled and assembled to be served as one part of the pump body (3). The diameter of the wear resisting board (5) is bigger than the diameter of an auxiliary impeller (7) and the diameter of the sealing box body (8). The utility model has simple structure and convenient manufacture. The wear resisting board enables components in the pump body to be conveniently disassembled and assembled from the end of a pump cover.
Description
One, technical field:
The utility model belongs to the equipment for liquid transportation technical field, is specifically related to a kind of Chemical Manufacture technology that is used for and carries the various centrifugal pumps easy to assemble that contain particle, corrosive liquids.
Two, background technique:
In the chemical centrifugal pump that industries such as chemical industry, metallurgy, pharmacy are used, the suction port design of most of chemical centrifugal pump is on the pump housing in the axial outside of pump shaft, other workpieces axially are installed in the inside and outside both sides of Seal cage respectively along pump shaft, maintenance or maintenance necessary two ends dismounting simultaneously, promptly all want parts such as detaching pipelines or coupling, could change the parts in the pump housing, very inconvenient, not only time-consuming but also can influence production, even bring unnecessary loss to manufacturing enterprise.For this reason, the design people has developed a kind of centrifugal pump easy to assemble through concentrating on studies, and has overcome the deficiency on the disassembly and assembly structure that existing centrifugal pump exists, and the evidence effect is good.
Three, innovation and creation content
1, the technical problem that will solve
It is a kind of simple in structure that the purpose of this utility model is to provide, and processing and fabricating is convenient, is easy to dismounting, the convenient centrifugal pump of safeguarding.
2, technological scheme
The purpose of this utility model is achieved in that on the anterior pump housing of its impeller the part of removable wear plate as the pump housing is set that the diameter of wearing plate is greater than the diameter of pump inner pieces such as sub-propeller, sealed letter body.
3, beneficial effect
Because the utility model is provided with dismountable wearing plate on its pump housing, make it possible to the parts in the pump housing are removed and installed easily from the pump cover end.
Four, description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.
Accompanying drawing is that the utility model is at a kind of enforcement state master sectional view that does not have on the leakage centrifugal pump.
Five, embodiment
As shown in the figure, the utility model centrifugal pump easy to assemble comprises the pump housing 3, pump shaft 13, impeller 4, pump cover 1, sealed member 15, carriage member 9 parts.Impeller 4 is installed on an end of pump shaft 13 by impeller nut 2, is installed in the pump housing by pump cover 1; Anterior coaxial short sleeve 6, axle sleeve 12, the throwing hydrosphere 14 of installing successively of impeller 4, axle sleeve 12 outer device sealed letter bodies 8, realize mechanical seal by stuffing box packing 15 between sealed letter body 8 and the axle sleeve 12, mechanical seal end cap 10 and sealed letter body 8 are by flange, screw rod 16 Joints on loose flange 11, the sealed letter body 8.
On the impeller 4 anterior pump housings 3 part of removable wear plate 5 as the pump housing 3 is set, the diameter of wearing plate 5 is greater than the diameter of pump inner pieces such as sub-propeller 7, sealed letter body 8.
Can adopt between wearing plate 5 and the pump housing 3 to be threaded, also can adopt easy-to-dismount modes such as bolt or crimping to connect, all not influence the realization of the utility model purpose.
Working principle of the present utility model:
Owing to be provided with dismantled and assembled wearing plate 5 at the pump housing, and its diameter is greater than the diameter of inside components such as sub-propeller 7, sealed letter body 8, make and on the pump housing, to form a bigger hole immediately, thereby can be when dismounting easily with the parts in the pump housing, take out the convenient maintenance and the part replacement of pump as sub-propeller, sealed letter body and sealed member thereof.
The utlity model has simple in structure, the characteristics that processing and fabricating is easy.Mounting structure to existing centrifugal pump has carried out bigger improvement, and convenient pump housing maintenance, maintenance and replacing component have improved working efficiency.Therefore, promotion and implementation the utility model will be obtained good economic benefit.
