Abstract
A guide vane body structure of a submersible axial-flow pump comprises a guide vane body, a mechanical seal seat, a mechanical seal, an elastic check ring and an impeller seat, wherein the guide vane body is arranged on a pump shaft; the guide vane body is internally provided with an integrated intermediate plate, the center of the intermediate plate is provided with a shaft hole for the pump shaft to pass through, the mechanical seal seat is cast with the shaft hole of the intermediate plate and the surface of the intermediate plate facing the impeller seat into a whole, the inner edge of the end surface of the mechanical seal seat facing the impeller seat is provided with a circle of positioning groove along the circumferential direction, one end of the mechanical seal is abutted to the positioning groove to realize axial limiting of one end, and the other end of the mechanical seal is axially limited by an elastic retaining ring. The guide vane body and the mechanical seal seat are cast into a whole, so that the casting processes on the guide vane body and the mechanical seal seat are reduced, the assembly of the submersible axial flow pump is simplified, the water inlet hidden trouble points at the matching position of the original guide vane body and the mechanical seal seat are reduced, and the submersible axial flow pump is more reliable and stable in operation.
Description
Technical Field
The utility model relates to a dive axial-flow pump, in particular to dive axial-flow pump guide vane body structure.
Background
Referring to fig. 1, the existing submersible axial-flow pump is provided with two or three mechanical seals, the first mechanical seal 3 is in direct contact with a medium and is arranged between a guide vane body 1 and an impeller seat 5 to play a role in sealing an oil chamber of the water pump. One end of the mechanical seal 3 is fixed on a pump shaft 6 by an elastic retainer ring 4, the other end is fixedly connected with the guide vane body 1 by a mechanical seal seat 2 through a screw 8, and an O-shaped ring 7 is arranged between the mechanical seal seat 2 and the guide vane body 1 for sealing. However, the space of the machine seal cavity is narrow, and the screwing consumes time and labor. And the possibility of leakage exists between the machine seal sealing seat 2 and the guide vane body 1.
SUMMERY OF THE UTILITY MODEL
The utility model provides an above-mentioned problem, a dive axial-flow pump guide vane body structure is provided.
The purpose of the utility model can be realized by the following technical scheme: a guide vane body structure of a submersible axial-flow pump comprises a guide vane body, a mechanical seal seat, a mechanical seal, an elastic check ring and an impeller seat, wherein the guide vane body is arranged on a pump shaft; the inside of the guide vane body is equipped with even intermediate lamella as an organic whole, the shaft hole that supplies the pump shaft to pass is seted up at the center of intermediate lamella, mechanical seal seat and the shaft hole of intermediate lamella and the face casting towards the impeller seat of intermediate lamella are integrative, and mechanical seal seat's terminal surface inner edge towards the impeller seat is equipped with the round constant head tank along circumference, it is spacing that mechanical seal's one end supports the axial that realizes one end in the constant head tank, and mechanical seal's the other end passes through the axial that circlip realized the other end and spacing.
Compared with the prior art, the beneficial effects of the utility model are that: the guide vane body and the mechanical seal seat are cast into a whole, so that the casting processes on the guide vane body and the mechanical seal seat are reduced, the assembly of the submersible axial flow pump is simplified, the water inlet hidden trouble points at the matching position of the original guide vane body and the mechanical seal seat are reduced, and the submersible axial flow pump is more reliable and stable in operation.

1 guide blade body
101 middle plate
102 axle hole
2 mechanical seal seat
3 mechanical seal
4 elastic retainer ring
5 impeller seat
6 pump shaft

8, a screw.
Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings to make it clear to those skilled in the art how to practice the invention. While the invention has been described in connection with its preferred embodiments, these embodiments are intended to be illustrative, and not to limit the scope of the invention.
Referring to fig. 2, a guide vane structure of a submersible axial-flow pump includes a guide vane 1 mounted on a pump shaft 6, a mechanical seal seat 2, a mechanical seal 3, an elastic retainer ring 4, and an impeller seat 5.
The inside of the guide vane body 1 is equipped with even intermediate plate 101 as an organic whole, the shaft hole 102 that supplies pump shaft 6 to pass is seted up at the center of intermediate plate 101, mechanical seal seat 2 and intermediate plate 101's shaft hole 102 and intermediate plate 101's the face towards impeller seat 5 cast into an organic whole, and mechanical seal seat 2's the terminal surface inner edge towards impeller seat 5 is equipped with the round constant head tank along circumference, mechanical seal 3's one end supports realizes the axial of one end spacing in the constant head tank, and mechanical seal 3's the other end passes through circlip 4 and realizes that the axial of the other end is spacing.
Because the guide vane body 1 and the mechanical seal seat 2 are cast into a whole, the original screw connection between the guide vane body 1 and the mechanical seal seat 2 is directly eliminated, the process of casting connecting holes on the guide vane body 1 and the mechanical seal seat 2 is reduced, and the process of casting an O-shaped ring groove on the guide vane body 1 is reduced, so that the assembly of the submersible axial flow pump is simplified, the water inlet hidden trouble points at the O-shaped ring groove on the original guide vane body 1 are reduced, and the operation of the submersible axial flow pump is more reliable and stable.
It should be noted that many variations and modifications of the embodiments of the present invention are possible, which are fully described, and are not limited to the specific examples of the above embodiments. The above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. In conclusion, the scope of the present invention should include those changes or substitutions and modifications which are obvious to those of ordinary skill in the art.
