Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump mechanical seal technology, and in particular to a water pump mechanical seal structure that can be quickly disassembled and maintained. Background Technology
[0002] Water pumps are widely used in industrial production, agricultural irrigation, and daily life. As a key component of water pumps, the mechanical seal directly affects the pump's operating efficiency and service life. Existing pump mechanical seal structures typically use multiple bolts for fixing. During maintenance and replacement, workers need to unscrew each bolt one by one with tools, which is cumbersome and time-consuming, greatly increasing maintenance costs and downtime, which is detrimental to the use of the water pump. Therefore, we propose a water pump mechanical seal structure that can be quickly disassembled and maintained. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a water pump mechanical seal structure that allows for quick disassembly and maintenance. This invention solves the problem that existing pump mechanical seal structures typically use multiple bolts for fixing, requiring workers to unscrew each bolt individually with tools during maintenance and replacement. This cumbersome operation and time-consuming disassembly process significantly increase maintenance costs and downtime, negatively impacting pump performance.
[0004] This utility model discloses a water pump mechanical seal structure that allows for quick disassembly and maintenance, comprising a stationary ring, a rotating ring seat on one side of the stationary ring, a first connecting ring on the rotating ring seat near the stationary ring, a second connecting ring on the stationary ring near the rotating ring seat, a plurality of fixed seats arranged in a matrix on the first connecting ring, a shaft in the center of the fixed seat, a threaded rod in the center of the shaft, a fixed plate matching the fixed seat on the second connecting ring, a clearance groove matching the threaded rod in the center of the fixed plate, a nut on the side of the threaded rod away from the fixed seat in the clearance groove, a rotating block on the side of the nut away from the second connecting ring, a spring on the end of the rotating ring seat away from the stationary ring, a base on the side of the spring away from the rotating ring seat, and a rotating ring inside the rotating ring seat.
[0005] In the above scheme, the outer side of the rotating block is provided with anti-slip grooves.
[0006] In the above scheme, a first sealing ring is provided between the moving ring and the moving ring seat.
[0007] In the above scheme, the inner wall of the stationary ring is provided with two symmetrical mounting grooves, and a second sealing ring is provided in the mounting groove.
[0008] In the above scheme, a sealing gasket is provided between the first connecting ring and the second connecting ring.
[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a water pump mechanical seal structure that can be quickly disassembled and maintained. When the threaded rod is located inside the clearance groove, the nut is fixedly connected to the rotating block. Rotating the rotating block causes the nut to rotate, and the nut moves towards the second connecting ring, so that the nut squeezes the second connecting ring. Through the mutual cooperation between the threaded rod and the nut, the first connecting ring and the second connecting ring can fit tightly together. The nut can be rotated by the rotating block, so that the operator can disassemble and assemble the water pump mechanical seal structure without tools. This sealing structure has a good sealing effect, is easy to install and disassemble, reduces the cumbersomeness of installing and disassembling the sealing structure, and is more convenient for the use of the water pump.

Detailed Implementation
[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0015] like Figure 1-2As shown, this utility model is a water pump mechanical seal structure that can be quickly disassembled and maintained. It includes a stationary ring 1, a rotating ring seat 2 on one side of the stationary ring 1, a first connecting ring 3 on the side of the rotating ring seat 2 near the stationary ring 1, and a second connecting ring 4 on the side of the stationary ring 1 near the rotating ring seat 2. The first connecting ring 3 has multiple fixed seats 5 arranged in a matrix. A shaft 6 is located in the center of each fixed seat 5, with both ends of the shaft 6 movably connected to the fixed seat 5, allowing a threaded rod 7 to rotate around the fixed seat 5 via the shaft 6. A threaded rod 7 is located in the center of the shaft 6. The second connecting ring 4 has a fixing plate 8 that matches the fixed seat 5. The fixing plate 8 has a relief groove 17 in the center that matches the threaded rod 7. The threaded rod 7 is located on the side of the relief groove 17 away from the fixed seat 5. Nut 9, with a rotating block 10 on the side away from the second connecting ring 4. When the threaded rod 7 is inside the clearance groove 17, nut 9 and rotating block 10 are fixedly connected. Rotating rotating block 10 causes nut 9 to rotate, moving nut 9 towards the second connecting ring 4, thus squeezing the second connecting ring 4. Through the cooperation between threaded rod 7 and nut 9, the first connecting ring 3 and the second connecting ring 4 can fit tightly together. Nut 9 can be rotated by rotating block 10, allowing workers to disassemble and assemble the water pump mechanical seal structure without tools. The moving ring seat 2 has a spring 11 on the side away from the stationary ring 1, and a base 12 on the side of the spring 11 away from the moving ring seat 2. The moving ring seat 2 contains a moving ring 13.
[0016] The outer side of the rotating block 10 is provided with anti-slip grooves, which effectively increase the friction between the palm and the rotating block 10, making it easier for the operator to rotate the rotating block 10.
[0017] A first sealing ring 14 is provided between the moving ring 13 and the moving ring seat 2. The provision of the first sealing ring 14 effectively increases the sealing performance between the moving ring 13 and the moving ring seat 2.
[0018] The inner wall of the stationary ring 1 is provided with two symmetrical mounting grooves 15, and a second sealing ring 16 is provided in the mounting groove 15. The setting of the second sealing ring 16 effectively increases the sealing between the stationary ring 1 and the drive shaft.
[0019] A sealing gasket 18 is provided between the first connecting ring 3 and the second connecting ring 4. The sealing gasket 18 effectively increases the sealing performance between the first connecting ring 3 and the second connecting ring 4.
[0020] Specifically, in this utility model, when the threaded rod 7 is located inside the clearance groove 17, the nut 9 is fixedly connected to the rotating block 10. Rotating the rotating block 10 causes the nut 9 to rotate, and the nut 9 moves towards the second connecting ring 4, so that the nut 9 squeezes the second connecting ring 4. Through the mutual cooperation between the threaded rod 7 and the nut 9, the first connecting ring 3 and the second connecting ring 4 can fit tightly together. The nut 9 can be rotated by the rotating block 10, so that the operator can disassemble and assemble the mechanical seal structure of the water pump without tools. The anti-slip groove effectively increases the friction between the palm and the rotating block 10, making it easier for the operator to rotate the rotating block 10. The setting of the first sealing ring 14 effectively increases the sealing between the moving ring 13 and the moving ring seat 2. The setting of the second sealing ring 16 effectively increases the sealing between the stationary ring 1 and the drive shaft. The setting of the sealing gasket 18 effectively increases the sealing between the first connecting ring 3 and the second connecting ring 4.
[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
