Description

Technical Field

[0001] The present invention relates to the technical field of water pump seals, and more particularly to a water pump seal with an early warning function. Background Art

[0002] Water pump seals are important components to ensure the normal operation of water pumps. They are mainly used to prevent liquid leakage and external contaminants from entering the pump body. Common types of seals include mechanical seals, packing seals and O-ring seals. Various seals use different materials such as rubber, polytetrafluoroethylene (PTFE), metal and graphite to adapt to different working conditions and media characteristics. Mechanical seals maintain the sealing effect through friction, packing seals rely on the compression of the packing to prevent leakage, and O-rings form seals through compression deformation. In order to ensure the long-term effectiveness of seals, regular inspection, lubrication and cleaning are necessary maintenance measures. Common problems include leakage, overheating and corrosion, which may be caused by material aging, insufficient lubrication or improper material selection.

[0003] Existing water pump seals play an important role in water pump operation, mainly including preventing liquid leakage, protecting the pump body, maintaining system pressure, improving work efficiency, reducing noise and vibration, and adapting to various working conditions. By effectively sealing the pump body, the seal can not only prevent liquid leakage, maintain the pressure and position of the internal medium, but also prevent external contaminants from entering, ensuring the cleanliness and normal operation of the pump. In addition, good sealing performance improves the working efficiency of the pump and reduces energy consumption and maintenance costs. Different types of seals can adapt to different working conditions according to specific application requirements, ensuring the safe and reliable operation of equipment in industries such as industry, agriculture and construction.

[0004] However, current water pump seals can no longer serve as a warning after failure or performance degradation. Even if leakage occurs, it cannot be prevented and controlled in time. Long-term leakage will not only become more and more serious, but will also cause a waste of resources.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a water pump seal with an early warning function. Summary of the invention

[0006] The purpose of the present invention is to provide a water pump seal with an early warning function to solve the above-mentioned problem.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A water pump seal with an early warning function comprises a sealing body, an early warning ring and a pair of sealing composite rings, wherein a spring is fixedly connected to the lower end of the sealing body, a static ring body is fixedly connected to the lower end of the spring, the early warning ring matches the sealing body, the early warning ring is located on the outside of the sealing body, a positioning ring is fixedly connected to the upper end of the sealing body, the positioning ring is provided with a dynamic ring body matching the sealing body, and the inner diameter of the dynamic ring body is equal to the outer diameter of the positioning ring, a pair of the sealing composite rings are respectively embedded in the inner and outer ends of the sealing body, and the pair of sealing composite rings are respectively an inner ring and an outer ring with different circular diameters, an auxiliary ring is fixedly connected to the outer end of the sealing body away from the spring, and the sealing body structure including the spring and the static ring body increases the stability and elasticity of the sealing performance, thereby ensuring effective sealing with the dynamic ring body, and at the same time, the setting of the early warning ring provides the seal with a function of real-time monitoring of leakage, thereby enhancing the safety of the system.

[0009] As a further improvement of the present invention, the sealing composite ring includes a pair of water absorption rings, the pair of water absorption rings are embedded in the sealing body, the water absorption rings are fixedly connected to a liquid guide ring at one end away from the sealing body, an expansion ring is fixedly connected in the middle of the pair of water absorption rings, and the expansion rings are fixedly connected to a pressure ring at one end away from the sealing body. The water absorption rings and liquid guide rings in the sealing composite ring are arranged to allow rapid absorption and transfer of moisture to the expansion rings when in contact with water, and the expansion rings further expand to enhance the sealing effect, thereby providing additional sealing force at the initial stage of moisture intrusion and reducing the risk of leakage.

[0010] As a further improvement of the present invention, the sealing composite ring also includes a magnetic panel, which is fixedly connected to the end of the pressure ring away from the expansion ring. An opening and closing ring is fixedly connected between a pair of liquid guiding rings. By adding the magnetic panel and combining it with the movement of the pressure ring, a method of mechanical conversion into a magnetic signal is provided. When the pressure ring moves due to the expansion of the expansion ring, the magnetic panel clings to the pump wall and activates the early warning, effectively issuing a leakage early warning.

[0011] As a further improvement of the present invention, the opening and closing ring includes a soft ring, which is fixedly connected between a pair of liquid guide rings, and a magnetic isolation ring is fixedly connected to one end of the soft ring away from the magnetic panel. Through the combination of the soft ring and the magnetic isolation ring in the opening and closing ring, not only the magnetic panel is protected from accidentally triggering the warning ring under normal circumstances, but also it can respond quickly when needed, thereby ensuring the sensitivity and accuracy of the warning mechanism.

[0012] As a further improvement of the present invention, the water absorption ring is made of natural fiber material, the liquid guide ring is made of foam material, and the expansion ring is made of expanded graphite. By adopting the water absorption ring made of natural fiber material, the liquid guide ring made of foam material and the expansion ring made of expanded graphite, the selection of these materials optimizes the water absorption and expansion characteristics, and enhances the adaptability and effect of the seal in different environments.

[0013] As a further improvement of the present invention, the pressure ring is made of silicone material, and the magnetic panel is made of soft magnetic material. The pressure ring made of silicone material and the magnetic panel made of soft magnetic material provide good deformation ability and adaptability, so that it can better fit with the pump wall when under pressure, thereby enhancing the reliability of sealing and early warning.

[0014] As a further improvement of the present invention, the soft ring is made of wear-resistant rubber material, and the magnetic isolation ring is made of magnetic shielding material. The soft ring made of wear-resistant rubber material and the magnetic isolation ring made of magnetic shielding material ensure the durability of the seal and the accuracy of magnetic control, extend the service life and reduce maintenance requirements.

[0015] As a further improvement of the present invention, the early warning ring includes a deformation ring, which is arranged on the outside of the sealing body, and a filling cavity is opened in the deformation ring, and the filling cavity is filled with a color developing liquid, and a plurality of cover blocks are arranged in the filling cavity, and a transparent ring is fixedly connected to the outer end of the deformation ring, and a plurality of magnetic sheets corresponding to the transparent ring are inlaid at one end of the transparent ring close to the cover block. Through the color developing liquid in the deformation ring and the cover block structure, an intuitive leakage indication is provided, so that the operator can quickly and effectively identify the leakage status by observing the color change.

[0016] As a further improvement of the present invention, the warning ring also includes multiple guide wires, and the multiple guide wires are fixedly connected to the inner end of the filling cavity, and the multiple cover blocks are respectively slidably connected to the outer ends of the multiple guide wires. The setting of the guide wires ensures the stability and accuracy of the cover blocks during movement, prevents overlapping or jamming during the warning process, and improves the reliability of the warning system.

[0017] As a further improvement of the present invention, the cover block includes a floating block, which is slidably connected to the outer end of the guide wire, and a magnetic block is embedded in the middle of the floating block. The end of the floating block away from the magnetic block is fixedly connected to a different-color block. Through the setting of the floating block, including the magnetic block and the different-color block, the functionality of the early warning ring is enhanced, so that the position and state of the cover block in the color developing solution are more obvious, which is convenient for quick judgment and response.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) This solution uses a pair of sealing composite rings, including an inner ring and an outer ring, as well as auxiliary water absorption rings, liquid guide rings, expansion rings and pressure rings, to achieve multi-stage sealing to effectively prevent liquid leakage and improve the reliability of the seal. The expansion ring expands after contacting water and can respond to changes in the sealing gap in a timely manner, ensuring that the sealing surface is always in close contact with the water pump wall, thereby further reducing the possibility of leakage.

[0020] (2) When the pressure ring moves due to the influence of moisture, the magnetic panel of this scheme interacts with the magnetic sheet of the warning ring to trigger the warning signal. This setting allows the problem to be discovered at the early stage of leakage and prevents the leakage from worsening. The color-developing liquid and the floating cover block in the warning ring make the color-developing liquid visible in the warning state, providing an intuitive leakage indication. The staff can quickly identify the sealing status by observing the color change and take timely measures.

[0021] (3) By adopting special materials such as wear-resistant rubber, magnetic shielding material, and natural fiber, the seal of the present invention is not only adaptable to a variety of working environments, but also has a long service life and strong environmental adaptability. The setting of the seal takes into account the convenience of installation and maintenance in actual operation. The setting of the auxiliary ring simplifies the installation process while ensuring that the sealing performance is immediately exerted after the initial installation.

[0022] (4) This solution shields the magnetism of the magnetic panel through a magnetic isolation ring to prevent the warning ring from being accidentally triggered under normal conditions, thereby improving the stability and reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-6 A water pump seal with an early warning function includes a seal body 1, an early warning ring 4 and a pair of sealing composite rings 7. A spring 2 is fixedly connected to the lower end of the seal body 1, and a static ring body 3 is fixedly connected to the lower end of the spring 2. The seal body 1 and the matching dynamic ring body 6 can form a seal with the pump body or the shaft, and the spring 2 is used to provide continuous pressure to ensure good contact between the sealing surfaces to prevent liquid leakage. The spring 2 is usually made of stainless steel or other corrosion-resistant materials to adapt to different working environments. At the same time, the static ring body 3 is used to maintain the stability of the seal during operation to prevent deviation and wear. Wear-resistant materials such as polyoxymethylene or polytetrafluoroethylene are usually used. The early warning ring 4 matches the seal body 1, and the early warning ring 4 is located outside the seal body 1. A positioning ring 5 is fixedly connected to the upper end of the sealing body 1. The positioning ring 5 is provided with a dynamic ring body 6 matching the sealing body 1, and the inner diameter of the dynamic ring body 6 is equal to the outer diameter of the positioning ring 5. A pair of sealing composite rings 7 are respectively embedded in the inner and outer ends of the sealing body 1, and the pair of sealing composite rings 7 are respectively an inner ring and an outer ring with different circular diameters. The sealing composite ring 7 can make the sealing surface and the contact surface of the pump body play an effective sealing role, and when water seepage occurs, it can not only prevent it in time, but also play an effective warning and reminder role with the cooperation of the early warning ring 4. An auxiliary ring 8 is fixedly connected to the outer end of the sealing body 1 away from the spring 2. The auxiliary ring 8 can make the installed seal play a preliminary auxiliary sealing role. Combined with multiple seals, the sealing effect of the seal can be effectively improved.

[0034] The sealing composite ring 7 includes a pair of water absorption rings 71, and the pair of water absorption rings 71 are embedded in the sealing body 1. The end of the water absorption ring 71 away from the sealing body 1 is fixedly connected with a liquid guide ring 72, and the middle of the pair of water absorption rings 71 is fixedly connected with an expansion ring 73, and the end of the expansion ring 73 away from the sealing body 1 is fixedly connected with a pressure ring 74. After the liquid guide ring 72 contacts with water, the moisture is transferred to the water absorption ring 71, so that the water absorption ring 71 absorbs the moisture and stores it, and then transfers it to the expansion ring 73, so that the expansion ring 73 expands after being damp, driving the pressure ring 74 to be close to the inner wall of the water pump to play a further sealing role and reduce leakage.

[0035] The sealing composite ring 7 also includes a magnetic panel 75, which is fixedly connected to the end of the pressure ring 74 away from the expansion ring 73. An opening and closing ring 76 is fixedly connected between a pair of liquid guiding rings 72. The pressure ring 74 is forced to move and squeeze the opening and closing ring 76, so that after the opening and closing ring 76 is opened, the magnetic panel 75 is close to the pump wall, and the warning ring 4 is triggered under the action of magnetic force to issue an early warning.

[0036] The opening and closing ring 76 includes a soft ring 761, which is fixedly connected between a pair of liquid guide rings 72. The end of the soft ring 761 away from the magnetic panel 75 is fixedly connected with a magnetic isolation ring 762. The magnetic panel 75 can be restricted by the soft ring 761 under normal conditions to prevent the magnetic force from accidentally touching the warning ring 4.

[0037] The water absorption ring 71 is made of natural fiber material, such as cotton, hemp and bamboo fiber, and has good water absorption. The liquid guide ring 72 is made of foam material, such as polyurethane foam, which may absorb water and expand when in contact with water, thereby increasing the porosity and effectively transferring moisture to the water absorption ring 71. The expansion ring 73 is made of expanded graphite, which will expand in volume when in contact with water or other liquids, thereby enhancing the sealing effect.

[0038] The pressure ring 74 is made of silicone material. When it is in contact with the pump wall, it can be deformed so that a larger area can be in contact with the pump wall. The magnetic panel 75 is made of soft magnetic material. The soft magnetic material not only makes it magnetic, but also when the pressure ring 74 is deformed, it can also be deformed and close to the pump wall to play a sealing role.

[0039] The soft ring 761 is made of wear-resistant rubber material, which can not only be deformed under force but also be used for a long time. The magnetic isolation ring 762 is made of magnetic shielding material. The magnetic isolation ring 762 is used to shield the magnetism of the magnetic panel 75 to prevent the magnetic panel 75 from triggering the warning ring 4 under normal conditions.

[0040] The early warning ring 4 includes a deformable ring 41, which is arranged on the outside of the sealing body 1. A filling cavity 42 is opened in the deformable ring 41, and the filling cavity 42 is filled with a color developing liquid. A plurality of cover blocks 43 are arranged in the filling cavity 42. A transparent ring 45 is fixedly connected to the outer end of the deformable ring 41. A plurality of magnetic sheets 46 corresponding to the transparent ring 45 are inlaid at one end close to the cover block 43. The cover block 43 is adsorbed by the magnetic sheet 46 and blocked on the inner surface of the transparent ring 45 so that the outer end of the early warning ring 4 is in a normal state, that is, a sealed state. When the magnetic panel 75 is close to the pump wall, the cover block 43 is attracted, so that the plurality of cover blocks 43 are separated from the inner surface of the transparent ring 45, so that the color developing liquid is exposed to play a warning role, thereby judging that there is a leakage in the water pump according to the color developing liquid, and the sealing member takes preventive measures.

[0041] The warning ring 4 also includes a plurality of guide wires 44, and the plurality of guide wires 44 are fixedly connected to the inner end of the filling cavity 42, and the plurality of cover blocks 43 are respectively slidably connected to the outer ends of the plurality of guide wires 44. The plurality of guide wires 44 guide the cover blocks 43 to prevent them from overlapping during movement, and the guide wires 44 can effectively control the cover blocks 43 to move along the guide wires 44, so that the cover blocks 43 can be accurately blocked by the inner surface of the transparent ring 45 when resetting.

[0042] The cover block 43 includes a floating block 431, which is slidably connected to the outer end of the guide wire 44. A magnetic block 432 is embedded in the middle of the floating block 431. A different-color block 433 is fixedly connected to the end of the floating block 431 away from the magnetic block 432. The magnetic block 432 can make the entire cover block 43 close to the inner surface of the transparent ring 45 under the magnetic attraction of the magnetic sheet 46, and when it is magnetically attracted by the magnetic panel 75, it can drive the cover block 43 to separate from the inner surface of the transparent ring 45. The floating block 431 can make the entire cover block 43 float in the color developing solution, and there is a color difference between the different-color block 433 and the color developing solution. The staff can judge the state of the seal by observing the color difference at the outer end of the warning ring 4.

[0043] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0044] The present invention realizes efficient multi-stage sealing by integrating a multi-layer sealing composite ring 7, a water absorption ring 71, a liquid guide ring 72, an expansion ring 73 and a pressure ring 74, effectively preventing liquid leakage and improving the reliability of sealing. The adaptive expansion ring 73 expands after contacting water, responds to the change of the sealing gap in time, ensures that the sealing surface is closely fitted to the water pump wall, and further reduces the possibility of leakage. The magnetic early warning mechanism uses the magnetic panel 75 to interact with the magnetic sheet 46 in the early warning ring 4 to trigger the early warning signal in time, so that the problem can be discovered at the early stage of leakage to prevent the leakage from worsening. The color developing liquid and the cover block 43 in the early warning ring 4 provide intuitive leakage indications, helping the staff to quickly identify the sealing status and take measures. At the same time, through the setting of the magnetic isolation ring 762, the early warning ring 4 is prevented from being accidentally touched under normal conditions, thereby enhancing the stability and reliability of the system. Therefore, the seal of the present invention not only improves the operating safety and maintenance efficiency of the water pump system, but also significantly enhances the convenience and practicality of equipment management through its innovative visual early warning setting.
