Description

Technical Field

[0001] This utility model belongs to the field of mechanical seal technology, and in particular relates to an adjustable mechanical seal structure for wear parts. Background Technology

[0002] Currently, mechanical seals are widely used for shaft sealing in applications such as transfer pumps and mixing tanks.

[0003] However, when the device is running, the rotating ring is driven, and the end face of the rotating ring contacts the end face of the stationary ring and causes a certain amount of wear. After long-term operation, due to wear, the gap between the two end faces gradually increases. The increased gap may cause the two end faces to no longer contact each other, and also cause the liquid film formed by the two end faces to fail, resulting in the leakage of the medium into the outside environment, polluting the environment, and also causing safety hazards. For this reason, we propose an adjustable mechanical seal structure for wear parts. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable mechanical seal structure for wear-prone parts. By incorporating a spring, the cooperation between the rotating ring and the stationary ring becomes crucial. A stable liquid film is formed between them, achieving a sealing effect. Throughout the entire operation, the elastic force accumulated by the spring continuously acts on the adjusting ring. This action ensures that the end faces of the rotating ring and the stationary ring are always tightly fitted together. This tight fit not only enhances the sealing effect but also, to a certain extent, avoids the problem of seal failure due to wear. This solves the problem in existing devices where, during operation, the rotating ring is driven, and the end faces of the rotating ring and the stationary ring come into contact and experience wear. After prolonged operation, due to wear, the gap between the two end faces gradually widens, which may cause the two end faces to no longer contact each other and also cause the liquid film formed between the two end faces to fail, resulting in media leakage into the external environment and pollution.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adjustable mechanical seal structure for wear parts, including a rotating ring seat, wherein a rotating ring is slidably connected to the right side of the rotating ring seat;

[0007] Several positioning shafts are fixedly connected to the left side of the rotating ring, and several positioning holes are opened on the right side of the rotating ring seat. The outer surface of the positioning shaft is inserted into the positioning hole. An auxiliary sealing ring of the rotating ring is fixedly connected inside the rotating ring. An adjusting ring is in contact with the left side surface of the rotating ring. Several limiting blocks are fixedly connected to the outer surface of the adjusting ring. Several sliding grooves are opened on the inner wall of the rotating ring seat. Several springs are in contact with the left side of the adjusting ring. A spring seat is provided on the left side of the spring. The outer surface of the spring seat is fixedly connected to the inner wall of the rotating ring seat. Several cylinders are fixedly connected to the right side of the spring seat. The outer surface of the cylinders is slidably connected to the inner wall of the adjusting ring. The elastic force accumulated by the spring will always act on the adjusting ring. This action will make the end face of the rotating ring and the end face of the stationary ring always fit tightly together. This tight fit not only enhances the sealing effect, but also avoids the sealing failure problem caused by wear to a certain extent.

[0008] Furthermore, a plurality of limiting grooves are provided on the right side of the inner wall of the moving ring seat. The limiting grooves are semi-circular. A plurality of limiting blocks are fixedly connected to the left side of the outer surface of the moving ring. The limiting blocks are semi-circular. The outer surface of the limiting blocks is inserted into the inside of the limiting grooves. The right side of the moving ring contacts the stationary ring. The outer surface of the stationary ring is inserted into the stationary ring seat. The setting of the limiting grooves greatly reduces the vibration generated by rotation and further ensures the stability of the moving ring during rotation.

[0009] Furthermore, a sealing ring one is in contact with the inner wall of the stationary ring seat, and the inner side of the sealing ring one is in contact with the outer surface of the stationary ring. A sealing ring two is provided on the left side of the sealing ring one, and the inner side of the sealing ring two is fixedly connected to the outer surface of the stationary ring. An auxiliary sealing ring for the stationary ring is fixedly connected to the inner wall of the stationary ring. Several anti-rotation holes are opened on the right side surface of the stationary ring, and several anti-rotation pins are inserted into the inner wall of the anti-rotation holes. The right side of several anti-rotation pins is fixedly connected to the left inner wall of the stationary ring seat. If the rotation of the moving ring is improper, it will cause the stationary ring to rotate. Through this design, the relative position between the moving ring and the stationary ring is kept stable, thereby ensuring the reliability of the entire sealing device.

[0010] This utility model has the following beneficial effects:

[0011] This invention utilizes a spring, specifically the crucial cooperation between the moving ring and the stationary ring, to form a stable liquid film that achieves a sealing effect. Throughout the entire operation, the spring force continuously acts on the adjusting ring, ensuring that the end faces of the moving ring and the stationary ring remain tightly fitted together. This tight fit not only enhances the sealing effect but also, to a certain extent, prevents sealing failure due to wear.

[0012] This invention incorporates an anti-rotation pin, which plays a crucial role in the mechanical seal device. The anti-rotation pin is precisely inserted into the anti-rotation hole of the stationary ring, effectively limiting the stationary ring's position. This limiting function is vital because it prevents the rotating ring from improperly causing the stationary ring to rotate when the end faces of the rotating ring and stationary ring come into contact and rub against each other. This design ensures the stability of the relative position between the rotating and stationary rings, thereby guaranteeing the reliability of the entire sealing device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-7 As shown, this utility model is an adjustable mechanical seal structure for wear parts, including a rotating ring seat 1, and a rotating ring 11 is slidably connected to the right side of the rotating ring seat 1;

[0026] A plurality of positioning shafts 111 are fixedly connected to the left side of the rotating ring 11. A plurality of positioning holes 112 are provided on the right side of the rotating ring seat 1. The outer surface of the positioning shafts 111 is inserted into the positioning holes 112. An auxiliary sealing ring 114 is fixedly connected inside the rotating ring 11. An adjusting ring 117 is in contact with the left side surface of the rotating ring 11. A plurality of limit blocks 172 are fixedly connected to the outer surface of the adjusting ring 117. A plurality of sliding grooves 171 are provided on the inner wall of the rotating ring seat 1. A plurality of springs 116 are in contact with the left side of the adjusting ring 117. A spring seat 115 is provided on the left side of the springs 116. The outer surface of the spring seat 115 is fixedly connected to the inner wall of the rotating ring seat 1. Several cylinders 161 are fixedly connected on the right side. The outer surface of the cylinders 161 is slidably connected to the inner wall of the adjusting ring 117. In this utility model, the cooperation between the moving ring 11 and the stationary ring 12 is crucial by setting a spring 116. A stable liquid film is formed between them, thereby achieving a sealing effect. During the entire working process, the elastic force accumulated by the spring 116 will always act on the adjusting ring 117. This action will make the end face of the moving ring 11 and the end face of the stationary ring 12 always tightly fitted together. This tight fit not only enhances the sealing effect, but also avoids the problem of sealing failure caused by wear to a certain extent.

[0027] The right side of the inner wall of the moving ring seat 1 is provided with several limiting grooves 131, which are semi-circular. Several limiting blocks 113 are fixedly connected to the left side of the outer surface of the moving ring 11. The limiting blocks 113 are semi-circular and their outer surfaces are inserted into the limiting grooves 131. The right side of the moving ring 11 is in contact with the stationary ring 12, and the outer surface of the stationary ring 12 is inserted into the stationary ring seat 2.

[0028] A sealing ring 121 is in contact with the inner wall of the stationary ring seat 2. The inner side of the sealing ring 121 is in contact with the outer surface of the stationary ring 12. A sealing ring 122 is provided to the left of the sealing ring 121. The inner side of the sealing ring 122 is fixedly connected to the outer surface of the stationary ring 12. An auxiliary sealing ring 123 is fixedly connected to the inner wall of the stationary ring 12. Several anti-rotation holes 22 are opened on the right side surface of the stationary ring 12. Several anti-rotation pins 21 are inserted into the inner wall of the anti-rotation holes 22. The right side of the anti-rotation pins 21 is fixedly connected to the left inner wall of the stationary ring seat 2. This utility model provides anti-rotation pins. Specifically, the anti-rotation pin 21 plays a crucial role in the mechanical seal device. It is precisely inserted into the anti-rotation hole 22 of the stationary ring 12, thereby effectively limiting the stationary ring 12. This limiting function is crucial because it can prevent the rotational movement of the rotating ring 11 from improperly driving the stationary ring 12 to rotate when the end face of the rotating ring 11 contacts and rubs against the end face of the stationary ring 12. Through this design, the relative position between the rotating ring 11 and the stationary ring 12 is kept stable, thereby ensuring the reliability of the entire sealing device.

[0029] A specific application of this embodiment is as follows: The positioning shaft 111 of the moving ring 11 is precisely aligned with the positioning hole 112 of the moving ring seat 1 and smoothly inserted. Then, the moving ring 11 is pushed to the left, causing its left end to gradually contact the right side of the adjusting ring 117. Pushing the adjusting ring 117 causes it to move to the left and compress the spring 116. During compression, the spring 116 accumulates elastic force, preparing for subsequent sealing. Simultaneously, the anti-rotation hole 22 of the stationary ring 12 is aligned with the anti-rotation pin 21 inside the stationary ring seat 2 and carefully inserted. The anti-rotation pin 21 plays a crucial limiting role for the stationary ring 12, effectively preventing… When the end face of the rotating ring 11 contacts the end face of the stationary ring 12, the rotating ring 11 causes the stationary ring 12 to rotate unnecessarily. When the device starts to run, the rotating ring 11 will be driven and start to rotate. During this process, the cooperation between the rotating ring 11 and the stationary ring 12 becomes crucial. A stable liquid film will be formed between them to achieve a sealing effect. Throughout the entire working process, the elastic force stored in the spring 116 will always act on the adjusting ring 117. This action will make the end face of the rotating ring 11 and the end face of the stationary ring 12 always fit tightly together. This tight fit not only enhances the sealing effect, but also avoids the problem of sealing failure caused by wear to a certain extent.
