Description

Technical Field

[0001] The utility model relates to the technical field of water pump auxiliary structures, in particular to an adjustable gasket dedicated to a water pump. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. The sleeve in the water pump will produce friction with the sealing ring as the shaft rotates. After the water pump has been running for a long time, the friction between the sleeve and the sealing ring will wear out. When the wear is severe, the sleeve needs to be replaced. If the water pump is always running frequently, the sleeve replacement frequency will also be frequent, resulting in increased cost of use. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide an adjustable gasket specially used for a water pump, which can rely on the adjustable gasket to change the front and rear positions of the shaft sleeve, thereby increasing the service life of the shaft sleeve, reducing the number of times the shaft sleeve needs to be replaced, and reducing the cost of use.

[0004] The technical solution adopted by the utility model is an adjustable gasket specially used for a water pump, comprising a rotating shaft, a shaft sleeve and a sealing ring, wherein the sealing ring is provided with a first threaded hole, the sealing ring is connected to a housing through a first screw, the housing is provided with a second threaded hole, a third threaded hole, a fourth threaded hole, a first limiting groove and a second limiting groove, a first gasket is provided on one side of the shaft sleeve, a third gasket is provided on one side of the first gasket, the first gasket is connected to the second gasket, one end of the second gasket is connected to a limiting block, the other end of the second gasket is provided with a fifth threaded hole, and the second gasket is connected to the housing through a second screw.

[0005] A static ring is provided on one side of the third gasket, and the static ring is connected to the static ring seat.

[0006] The bottom end of the first screw passes through the third threaded hole and is located in the first threaded hole.

[0007] The thickness of the first gasket is 0.6 cm.

[0008] The thickness of the third gasket is 1.4 cm.

[0009] The shell is divided into two parts, an upper part and a lower part.

[0010] The beneficial effects of the utility model are as follows: the original gasket of the water pump is divided into a first gasket and a third gasket, the first gasket is fixedly connected to the second gasket, the second gasket is connected to the shell by a second screw, and the sealing ring is connected to the shell by the first screw; after the shaft sleeve and the sealing ring rub against each other for a long time, the first gasket and the second gasket can be moved to the rear end of the shaft sleeve, so that the wear interface of the shaft sleeve and the sealing ring is displaced, and the original friction position of the shaft sleeve and the sealing ring is changed, so that the shaft sleeve is used once more, the service time of the shaft sleeve is increased, the number of times the shaft sleeve is replaced is reduced, and the use cost is reduced.

DETAILED DESCRIPTION

[0014] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0015] Referring to the accompanying drawings, an adjustable gasket specially used for a water pump comprises a rotating shaft 1, a sleeve 2 and a sealing ring 3, and is characterized in that: a first threaded hole 4 is provided on the sealing ring 3, the sealing ring 3 is connected to a housing 6 through a first screw 5, a second threaded hole 7, a third threaded hole 8, a fourth threaded hole 9, a first limiting groove 10 and a second limiting groove 11 are provided on the housing 6, a first gasket 12 is provided on one side of the sleeve 2, a third gasket 19 is provided on one side of the first gasket 12, a second gasket 13 is connected to the first gasket 12, one end of the second gasket 13 is connected to a limiting block 14, the other end of the second gasket 13 is provided with a fifth threaded hole 15, and the second gasket 13 is connected to the housing 6 through a second screw 16.

[0016] A stationary ring 17 is provided on one side of the third gasket 19 , and the stationary ring 17 is connected to a stationary ring seat 18 .

[0017] The bottom end of the first screw 5 passes through the third threaded hole 8 and is located in the first threaded hole 4 .

[0018] The thickness of the first gasket 12 is 0.6 cm.

[0019] The third gasket 19 has a thickness of 1.4 cm.

[0020] The housing 6 is divided into two parts, an upper part and a lower part.

[0021] When the adjustable gasket dedicated to the water pump is used, the original gasket is replaced with the first gasket 12 and the third gasket 19. The first gasket 12 is located at the front end of the sleeve 2 and connected to the second gasket 13. When the sleeve 2 is just used, the first gasket 12 and the third gasket 19 are put together. First, the sealing ring 3 is sleeved on the sleeve 2, and then the second limiting groove 11 on the upper part of the shell 6 is aligned with the limiting block 14 to lower the upper part of the shell 6, and the first screw 5 is screwed into the third threaded hole 8 and the first threaded hole 4, and the second screw 16 is screwed into the fourth threaded hole 9 and the fifth threaded hole 15 to fix the upper part of the shell 6. Similarly, the lower part of the shell 6 is fixed. After the sleeve 2 has been used for a period of time, the sleeve 2 and the sealing ring are fixed. The contact surface of the ring 3 will wear. When the wear reaches a certain extent, the upper part of the shell 6 and the lower part of the shell 6 are removed, and then the sealing ring 3 is removed, and then the sleeve 2 and the first gasket 12 are removed, and then the sleeve 2 is first sleeved on the rotating shaft 1 so that the front end of the sleeve 2 contacts with the third gasket 19, and then the sealing ring 3 is sleeved on the sleeve 2, and then the first gasket 12 is sleeved on the rotating shaft 1 and contacts with the rear end of the sleeve 2, and then the first limit groove 10 in the upper part of the shell 6 is aligned with the limit block 14 to lower the upper part of the shell 6, and then the upper part of the shell 6 and the lower part of the shell 6 are fixed with the first screw 5 and the second screw 16, so that the original friction position of the sleeve 2 and the sealing ring 3 is changed, so that the sleeve 2 can be used again.

[0022] The original gasket of the water pump is divided into a first gasket 12 and a third gasket 19, the first gasket 12 is fixedly connected to the second gasket 13, the second gasket 12 is connected to the housing 6 by a second screw 16, and the sealing ring 3 is connected to the housing 6 by a first screw 5. After the shaft sleeve 2 and the sealing ring 1 have rubbed for a long time, the first gasket 12 and the second gasket 13 can be moved to the rear end of the shaft sleeve 2, so that the wear interface of the shaft sleeve 2 and the sealing ring 3 is displaced, and the original friction position of the shaft sleeve 2 and the sealing ring 3 is changed, so that the shaft sleeve 2 is used once more, the service time of the shaft sleeve 2 is increased, the number of times the shaft sleeve 2 is replaced is reduced, and the use cost is reduced.
