Description

Technical Field

[0001] The utility model relates to the technical field of axial flow pumps, in particular to a fixing and clamping device for an axial flow pump. Background Art

[0002] An axial flow pump is a pump that transports liquid along the axial direction by the force exerted by the blades of a rotating impeller on the liquid. There are several types of pumps, including vertical, horizontal, inclined and cross-flow types.

[0003] At present, the fixing method of vertical axial flow pump is to place the pump body on the seat at the bottom of the tube, install the sealing ring at the pump shell position, and fix the pump body by the engagement of the sealing ring. At the same time, the friction between the pump body and the seat is increased by the pump body's own gravity to prevent the pump body from slipping and rotating during operation. However, in the actual operation process, this fixing method is not ideal and cannot effectively prevent the pump body from slipping and rotating. At the same time, the sealing ring is easy to fall off during equipment pre-inspection and maintenance, resulting in failure of fixation. When the pump body rotates during operation, it is easy to cause the cable to be twisted and damaged, seriously affecting the safety of production operation.

[0004] Therefore, there is a need for an axial flow pump fixing and locking device which is easy to operate, has stable limit and prevents the pump body from shaking. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes an axial flow pump fixing clamping device, which has the characteristics of convenient operation and stable installation.

[0006] In order to achieve the above purpose, the utility model proposes the following specific solutions:

[0007] An axial flow pump fixing and locking device comprises a base, a first steel pipe guide rail is fixedly provided on the top surface edge of the base, two first steel pipe guide rails are symmetrically provided, a second steel pipe guide rail is provided on one side of the first steel pipe guide rail, two second steel pipe guide rails are symmetrically provided, a limiting tube is fixedly provided on the top surface edge of the base, the limiting tube is located on the outside of the first steel pipe guide rail and the second steel pipe guide rail, an axial flow pump is inserted on the inner side of the limiting tube, and a limiting block is symmetrically fixedly provided on the lower end of the outer wall of the axial flow pump, and the limiting block is located between the first steel pipe guide rail and the second steel pipe guide rail.

[0008] As the preferred technical solution of the axial flow pump fixing and locking device of the utility model, the axial flow pump includes a pump body, an operating frame, a cable and a sealing gasket. The pump body is inserted into the inner side of the limiting tube, the operating frame is fixedly provided on the top edge of the pump body, the top surface of the pump body is electrically connected with a cable, and a sealing gasket is fixedly provided on the upper outer wall of the pump body.

[0009] As a preferred technical solution of the axial flow pump fixing and locking device of the utility model, a limiting groove is provided on the outer wall of the sealing gasket.

[0010] As a preferred technical solution of the axial flow pump fixing and locking device of the utility model, a locking groove is provided at the upper end of the inner wall of the limiting tube, and the sealing gasket is engaged with the inner side of the locking groove.

[0011] As a preferred technical solution of the axial flow pump fixing and locking device of the utility model, a limiting ring is fixedly provided on the inner wall of the locking groove, and the limiting ring is locked on the inner side of the limiting groove.

[0012] As a preferred technical solution of the axial flow pump fixing and locking device of the utility model, fixing plates are fixedly provided on both sides of the limit block, the fixing plates are fixed on the pump body, and fixing nails are provided on the fixing plates.

[0013] As a preferred technical solution of the axial flow pump fixing and positioning device of the utility model, a flexible clamping sleeve is fixedly provided on the outer side of the limit block, and the flexible clamping sleeve is located between the first steel pipe guide rail and the second steel pipe guide rail.

[0014] As a preferred technical solution of the axial flow pump fixing and locking device of the utility model, the limiting ring is made of a flexible material.

[0015] Compared with the existing technology, the utility model has the following beneficial effects:

[0016] The utility model symmetrically fixes two first steel pipe guide rails and second steel pipe guide rails on a base for arranging an axial flow pump by providing a first steel pipe guide rail, a second steel pipe guide rail and a limit block. The first steel pipe guide rail and the second steel pipe guide rail are symmetrically arranged on both sides of the axial flow pump. The limit blocks are symmetrically fixed at the lower end of the outer wall of the axial flow pump. When the axial flow pump is installed on the base, the limit blocks are placed between the first steel pipe guide rail and the second steel pipe guide rail, and the axial flow pump is vertically lowered and placed on the base. During the operation of the axial flow pump, the limit blocks are limited by the steel pipe guide rails to avoid the situation where the axial flow pump shakes during operation and causes the cable to be torn off by rotation, thereby improving the stability and safety of the operation of the axial flow pump.

[0017] And by fixing a flexible ferrule on the outside of the limit block, the flexible ferrule is located between the limit block and the two steel pipe guide rails.
