The technical scheme of the utility model is realized like this:
a mounting structure convenient for dismounting a wear-resistant ring comprises a shell, an impeller and the wear-resistant ring, wherein the wear-resistant ring is mounted on the inner circumferential surface of the shell, the inner circumferential surface of the wear-resistant ring is in contact with the impeller, so that the shell is sealed with the impeller, and two anti-rotation blocks are arranged on the outer circumferential surface of the wear-resistant ring at intervals; the inner surface of the shell is provided with an annular groove, the radius of the bottom of the annular groove is equal to the distance from the outer end of the anti-rotating block to the circle center of the wear-resistant ring, the shell is provided with two bayonets corresponding to the two anti-rotating blocks, the two bayonets are communicated with the annular groove, and the two anti-rotating blocks of the wear-resistant ring can enter the annular groove from the two bayonets to realize the clearance fit connection of the wear-resistant ring and the shell.
A stop block is arranged in the annular groove close to any bayonet to support the anti-rotation block to prevent the wear-resistant ring from doing circular motion, a blocking piece is fixedly arranged at the corresponding bayonet to prevent the anti-rotation block from withdrawing from the bayonet, and therefore the anti-rotation block is fixed between the stop block and the blocking piece in the annular groove.
Further, the blocking member is a grub screw.
Furthermore, the two anti-rotation blocks are symmetrically arranged on the outer circumferential surfaces of two ends of any diameter of the wear-resisting ring.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses set up on wear-resisting ring and prevent changeing the piece to through the stopper on the annular groove and block piece cooperateing, realize that wear-resisting ring is connected with casing booth clearance fit, this structure processing is simple, convenient operation when not only installing, when dismantling moreover, only need will block the piece and dismantle, then rotatory wear-resisting ring just can dismantle wear-resisting ring get off, can not cause structural deformation simultaneously.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 2, 3, 4 and 5, a mounting structure for facilitating the disassembly of a wear-resistant ring comprises a housing 1, an impeller 2 and a wear-resistant ring 3, wherein the wear-resistant ring 3 is mounted on the inner circumferential surface of the housing 1 and the inner circumferential surface of the wear-resistant ring is in contact with the impeller 2 so as to realize the sealing between the housing 1 and the impeller 2, and two anti-rotation blocks 4 are arranged on the outer circumferential surface of the wear-resistant ring 3 at intervals; the inner surface of the shell 1 is provided with an annular groove 5, the radius of the bottom of the annular groove 5 is equal to the distance from the outer end of the anti-rotating block 4 to the circle center of the wear-resistant ring 3, the shell is provided with two bayonets (not shown in the figure) corresponding to the two anti-rotating blocks 4, the two bayonets are communicated with the annular groove 5, the two anti-rotating blocks 4 of the wear-resistant ring 3 can conveniently enter the annular groove 5 from the two bayonets, and the small clearance fit connection between the wear-resistant ring 3 and the.
A stop block 6 is arranged in the annular groove 5 close to any bayonet to abut against the rotation prevention block 4 to prevent the wear-resisting ring 3 from making circular motion, a blocking piece 7 is fixedly arranged at the corresponding bayonet to prevent the rotation prevention block 4 from withdrawing from the bayonet, and therefore the rotation prevention block 4 is fixed between the stop block 6 and the blocking piece 7 in the annular groove 5.
Therefore, the wear-resistant ring is connected with the shell in a small clearance fit mode and is in contact with the impeller, and sealing between the shell and the impeller is achieved. Simultaneously because of preventing the setting of piece, stop block and holding member to there the stop block only has a short segment distance apart from the bayonet socket, and through welded fastening in the annular groove, processing is convenient, and make when the pump operation, 360 circular motion can not be done in the annular groove to wear-resisting ring, only do the small-angle motion, thereby reduce the friction.
In a specific implementation, the blocking member 7 is a grub screw.
The flat head screw is used as the blocking piece, so that the wear-resisting ring is easy to obtain materials, convenient to mount and dismount and cannot be influenced.
In specific implementation, the two anti-rotation blocks 4 are symmetrically arranged on the outer circumferential surfaces of two ends of any diameter of the wear-resistant ring.
In this embodiment, the two anti-rotation blocks are fixed to the outer circumferential surface of the wear-resistant ring by welding.
When the utility model is installed, the anti-rotation block of the wear-resistant ring enters the annular groove from the bayonet, the width of the annular groove is slightly larger than that of the anti-rotation block of the wear-resistant ring, then the wear-resistant ring is rotated to enable the anti-rotation block to abut against the stop block, and then the flat head screw is fixedly installed in the annular groove at the bayonet, so that the anti-rotation block is fixed between the stop block of the annular groove and the flat head screw; when the wear-resistant ring is disassembled, the flat-head screw is directly rotated to disassemble the flat-head screw, then the wear-resistant ring is rotated to disassemble the wear-resistant ring from the bayonet, so that the shell, the annular groove and other structures cannot be deformed, and the wear-resistant ring is directly assembled after being replaced. The utility model is suitable for a large-scale single-stage pump.
