Abstract

The utility model discloses a kind of anti-corrosion half-opened impeller dismantling devices, including handle, circular ring shape mounting rack and dismounting head, the handle is 2 and is symmetrically arranged on circular ring shape mounting rack outer wall, the circular ring shape mounting rack inner wall is evenly distributed with several trapezoidal grooves, the trapezoidal groove is half through, the dismounting head shapes are adapted with the groove shape between the anti-corrosion half-opened impeller blade to be dismantled, the dismounting head bottom surface is equipped with T shape convex block, in the T shape convex block insertion trapezoidal groove, the T shape convex block is adapted with trapezoidal groove.The utility model structure is simple, and easy to operate one is achievable, intact can disassemble and install half-opened impeller, and it is short to dismount impeller time-consuming.

Description

A kind of anti-corrosion half-opened impeller dismantling device

Technical field

The utility model relates to dismounting impeller auxiliary tools, and in particular to a kind of anti-corrosion half-opened impeller dismantling device.

Background technique

Pump is the energy for converting mechanical energy into liquid, for the machinery of pressure-increasing unit liquid.Pump is answered in national economy There is extensive, universal universal machine, other than water conservancy, electric power, agricultural and mine etc. largely use, is produced and used with petrochemical industry especially It measures more.

Anti-corrosion semi-open impeller pump class equipment used now, corrosion of the medium to impeller in order to prevent, using fluoroplastics F46 pours impeller nut and impeller metal inner lining together, therefore intact half-opened impeller can not be dismantled and be pacified Dress.Installing impeller is the step of taking a long time, and the method generally used at present is pounded using hammer, and crowbar sled not only works in this way Efficiency is lower, labor intensity is larger, work progress security risk is larger, and is easily damaged accessory, causes member replacing rate high, Install and use the high problem of rear repair rate.

Utility model content

The purpose of the utility model is to overcome disadvantages of the existing technology, provide a kind of anti-corrosion half-opened impeller dismounting Tool.

To achieve the goals above, the technical solution of the utility model is: a kind of anti-corrosion half-opened impeller dismantling device, Be characterized in that: including handle, circular ring shape mounting rack and dismounting head, the handle is 2 and is symmetrically arranged on circular ring shape mounting rack Outer wall, the circular ring shape mounting rack inner wall are evenly distributed with several trapezoidal grooves, and the trapezoidal groove is half through, the ladder Connected in star external width is less than inner width, between dismounting head shapes and the anti-corrosion half-opened impeller blade to be dismantled Groove shape is adapted, and the dismounting head front-back is horizontal plane, other faces are curved-surface structure, and the dismounting head bottom surface is equipped with T shape convex block, the T shape convex block are inserted into trapezoidal groove, and the T shape convex block is adapted with trapezoidal groove.

Further；The handle and circular ring shape mounting rack junction are equipped with reinforcing rib.

The utility model has the beneficial effects that the utility model structure is simple, easy to operate one is achievable, can be intact Half-opened impeller is disassembled and installed, and dismount impeller time-consuming it is short.

Specific embodiment

Embodiment:

As shown in Figures 1 to 5, a kind of anti-corrosion half-opened impeller dismantling device, including handle 1, circular ring shape mounting rack 2 and tear open Head 3 is filled, the handle 1 is 2 and is symmetrically arranged on 2 outer wall of circular ring shape mounting rack, and the handle 1 connects with circular ring shape mounting rack 2 It meets place and is equipped with reinforcing rib 4,2 inner wall of circular ring shape mounting rack is evenly distributed with several trapezoidal grooves 21, the trapezoidal groove 21 It is half communicating structure in 2 front-rear side walls of circular ring shape mounting rack, 21 external width of trapezoidal groove is less than inner width, described Dismounting 3 shape of head is adapted with the groove shape between the anti-corrosion half-opened impeller blade to be dismantled, 3 front and back of dismounting head Face is horizontal plane, other faces are curved-surface structure, and 3 bottom surface of dismounting head is equipped with T shape convex block 31, and the T shape convex block 31 is inserted into In trapezoidal groove 21, the T shape convex block 31 is adapted with trapezoidal groove 21.

Embodiment described above is the preferable scheme of the utility model, is not made in any form to the utility model Limitation, on the premise of not exceeding the technical scheme recorded in the claims there are also other variations and modifications.
