Description

Technical Field

[0001] This utility model relates to the field of support rings, and more particularly to a support ring that is easy to install. Background Technology

[0002] In multi-segment split piston transmission systems of small and medium-sized petrochemical equipment, to ensure the radial positioning accuracy and structural stability of the piston during reciprocating motion, it is usually necessary to use supporting annular components. In the prior art, the commonly used support solution for this type of scenario is an open-type support ring. The ring body adopts a single-segment open design, relying on the elastic deformation of the ring body itself to achieve a tight fit with the inner wall of the piston body. Some open-type support rings also have a few simple protrusions on the outer wall of the ring body to help enhance the limiting effect with the piston body mounting slot, thereby meeting the support and positioning requirements of the equipment foundation.

[0003] However, the above-mentioned open-type support ring has some drawbacks when applied to multi-segment split piston bodies: because the ring body itself has an open structure, when subjected to the radial extrusion force and vibration generated by the reciprocating motion of the piston body for a long time, stress concentration points are easily formed at the opening, resulting in local irregular deformation of the ring body; this deformation will directly destroy the fitting accuracy of the joint between the support ring and the piston body segments, causing the support gap between the two to gradually increase, which not only reduces the positioning stability of the support ring on the piston body, but also increases the local friction loss during the piston movement, and may even cause the piston body to slightly deviate during the movement, thereby affecting the smoothness of operation and service life of the piston transmission system of petrochemical equipment.

[0004] Therefore, those skilled in the art have provided a support ring that is easy to install in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a support ring that is easy to install. The device embeds a metal positioning ring into the inner wall of the support ring body and achieves a tight fit between the two without relative displacement. This makes the support ring body less prone to deformation when subjected to the pressure of piston movement, and maintains the roundness and stability of the overall structure, thereby improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-install support ring includes a support ring body, a first protruding ring, a second protruding ring, and a metal positioning ring. The first protruding ring is fixedly connected to both ends of the outer wall of the support ring body, and a plurality of second protruding rings are fixedly connected to the middle of the outer wall of the support ring body. The metal positioning ring is embedded in the inner wall of the support ring body. Through the above technical solution, the device achieves a tight fit between the metal positioning ring and the inner wall of the support ring body without relative displacement by embedding the metal positioning ring inside the support ring body. This makes the support ring body less prone to deformation when subjected to the pressure of piston movement, and maintains the roundness and stability of the overall structure. By setting first protruding rings at both ends of the outer wall of the support ring body and setting multiple second protruding rings evenly distributed circumferentially in the middle, the device can enhance the positioning fit with the installation part through the protruding rings when installed with a multi-segment split piston body, and avoid misalignment after installation. By using carbon fiber material to make the support ring body and high-strength metal material to make the metal positioning ring, the device has both lightweight characteristics and wear resistance and compression resistance. It can adapt to the reciprocating motion environment of the piston body for a long time without being easily damaged, extending the service life and improving the practicality of the device.

[0007] Furthermore, the thickness of the first protruding ring is greater than the thickness of the second protruding ring; Through the above technical solution, the first protruding rings located at both ends of the support ring body can be more firmly locked at the end of the mounting groove of the multi-segment split piston body, forming a reliable axial limit. The thinner second protruding ring enhances the positioning effect in the middle of the support ring body while avoiding excessive occupation of the internal installation space of the piston body, effectively balancing the reliability of the limit and the adaptability of the space.

[0008] Furthermore, the main body of the support ring adopts a full-circle, openless structure, which is suitable for installation scenarios of multi-segment split piston bodies, making installation and operation convenient. The above technical solution allows for precise docking of the support ring body with the multi-segment split piston body without relying on the elastic deformation of the ring body. This not only reduces the risk of component damage caused by forcibly bending the open ring body during installation, but also eliminates the elastic reset adjustment step after the open ring body is installed, significantly improving installation efficiency and ease of operation.

[0009] Furthermore, the metal positioning ring is tightly fitted to the inner wall of the support ring body, and there is no relative displacement between the two, which can jointly maintain the roundness stability of the overall structure of the support ring. Through the above technical solution, the metal positioning ring and the main body of the support ring form a cohesive structure that shares the force. When the piston reciprocates and exerts radial pressure on the support ring, the metal positioning ring can directly disperse part of the external force, preventing local depressions or protrusions on the inner wall of the support ring, ensuring that the support ring always maintains a uniform fit with the inner wall of the piston, and ensuring the smoothness of the piston movement.

[0010] Furthermore, the support ring body is made of carbon fiber, which gives the support ring body both lightweight and wear-resistant properties, making it suitable for long-term use. Through the above technical solutions, while reducing the overall weight of the support ring and the reciprocating load on the piston body, the excellent wear resistance of carbon fiber material reduces the daily frictional wear between the support ring body and the inner wall of the piston body, avoiding the increase in support gap caused by ring wear after long-term use, effectively extending the service life of the support ring, and adapting to the working conditions of long-term continuous operation of petrochemical equipment.

[0011] Furthermore, both the first protruding ring and the second protruding ring are integrally formed with the main body of the support ring, and the outer walls of the first protruding ring and the second protruding ring are smooth arc surfaces, which can play a guiding role during installation. The above technical solution improves the connection strength between the first protruding ring, the second protruding ring and the main body of the support ring, preventing the protruding ring from falling off due to force during installation or use. On the other hand, the smooth arc surface reduces the frictional resistance between the protruding ring and the piston body mounting hole during installation, guides the support ring to smoothly enter the preset installation position, and reduces scratch damage to the surface of the component during installation.

[0012] Furthermore, the metal positioning ring is made of high-strength metal, which can effectively suppress the deformation of the support ring body during use and ensure the overall performance of the support ring; Through the above technical solution, the excellent deformation resistance of high-strength metal material is used to provide a rigid support skeleton for the main body of the support ring. When the main body of the support ring is subjected to piston vibration or pressure impact, the metal positioning ring can directly offset part of the external force, prevent the main body of the support ring from bending, twisting or other deformations, and ensure that the support ring always maintains the preset structural shape, thus ensuring its stable positioning and support performance for the piston.

[0013] Furthermore, multiple second protruding rings are evenly distributed along the circumference of the support ring body, which can enhance the positioning stability of the support ring and the installation part and prevent displacement after installation. The above technical solution enables the second protruding ring to form a uniform radial support force on the middle part of the support ring body, so that the contact surface between the support ring and the piston body installation part is subjected to balanced force, preventing the support ring from shifting circumferentially during piston body movement due to the lack of local support points, further improving the positioning stability of the support ring, and reducing abnormal friction and noise caused by shift.

[0014] This utility model has the following beneficial effects: 1. The present invention proposes a support ring that is easy to install. The device embeds a metal positioning ring into the inner wall of the support ring body and achieves a tight fit between the two without relative displacement. This makes the support ring body less prone to deformation when subjected to the pressure of piston movement, and maintains the roundness stability of the overall structure, thereby improving the practicality of the device.

[0015] 2. The present invention proposes a support ring that is easy to install. The device has a first protruding ring at both ends of the outer wall of the main body of the support ring and a plurality of second protruding rings evenly distributed in the circumferential direction in the middle. When the device is installed with a multi-segment split piston body, the protruding rings can enhance the positioning fit with the installation part and prevent the device from shifting after installation, thus improving the practicality of the device.

[0016] 3. The present invention proposes a support ring that is easy to install. The device uses carbon fiber to make the support ring body and high-strength metal to make the metal positioning ring. This makes the device both lightweight and wear-resistant and compression-resistant. It can adapt to the reciprocating motion environment of the piston body for a long time without being easily damaged, thus extending the service life and improving the practicality of the device.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-3 This utility model provides a specific implementation method: An easy-to-install support ring includes a support ring body 1, a first protruding ring 2, a second protruding ring 3, and a metal positioning ring 4. The first protruding ring 2 is fixedly connected to both ends of the outer wall of the support ring body 1, and multiple second protruding rings 3 are fixedly connected to the middle of the outer wall of the support ring body 1. The metal positioning ring 4 is embedded in the inner wall of the support ring body 1. By embedding the metal positioning ring 4 into the inner wall of the support ring body 1 and achieving a tight fit without relative displacement, the support ring body 1 is less prone to deformation when subjected to the pressure of piston movement, thus maintaining its overall integrity. To ensure the roundness and stability of the structure, first protruding rings 2 are set at both ends of the outer wall of the support ring body 1, and multiple second protruding rings 3 are set in the middle and evenly distributed along the circumference. When the device is installed with the multi-segment split piston body, the protruding rings can enhance the positioning and fit of the installation part, and avoid the displacement after installation. By using carbon fiber material to make the support ring body 1 and high-strength metal material to make the metal positioning ring 4, the device has both lightweight characteristics and wear resistance and compression resistance. It can adapt to the reciprocating motion environment of the piston body for a long time without being easily damaged, thus extending the service life and improving the practicality of the device.

[0021] Reference Figure 3-5 The thickness of the first protruding ring 2 is greater than that of the second protruding ring 3, so that the first protruding ring 2 located at both ends of the support ring body 1 can be more firmly locked at the end of the mounting groove of the multi-segment split piston body, forming a reliable axial limit. The thinner second protruding ring 3 enhances the positioning effect in the middle of the support ring body 1 while avoiding excessive occupation of the internal mounting space of the piston body, effectively balancing the reliability of the limit and the space adaptability. The support ring body 1 adopts a full-circle, open-end structure, which is suitable for the installation of multi-segment split piston bodies. The installation operation is convenient. The support ring body 1 can be directly and precisely connected to the connection part of the multi-segment split piston body without relying on the elastic deformation of the ring body. This not only reduces the risk of component damage caused by forcibly bending the open ring body during installation, but also eliminates the elastic reset adjustment step after the open ring body is installed, significantly improving installation efficiency and ease of operation. The metal positioning ring 4 fits tightly against the inner wall of the support ring body 1, with no relative displacement between them. Together, they can maintain the roundness stability of the overall structure of the support ring, allowing the metal positioning ring 4 and the support ring body 1 to form a cohesive structure that shares the load. When the piston body reciprocates and exerts radial pressure on the support ring, the metal positioning ring 4 can directly disperse some of the external force, preventing local depressions or protrusions on the inner wall of the support ring body 1. This ensures that the support ring always maintains a uniform fit with the inner wall of the piston body, guaranteeing the smoothness of the piston movement. The support ring body 1 is made of carbon fiber, which makes the support ring body 1 both lightweight and wear-resistant, suitable for long-term use. While reducing the overall weight of the support ring and reducing the reciprocating load on the piston body, the excellent wear resistance of carbon fiber reduces the daily friction wear between the support ring body 1 and the inner wall of the piston body, avoiding the increase in support gap due to ring wear after long-term use, effectively extending the service life of the support ring, and meeting the working conditions of long-term continuous operation of petrochemical equipment. Both the first protruding ring 2 and the second protruding ring 3 are integrally formed with the support ring body 1, and the outer walls of the first protruding ring 2 and the second protruding ring 3 are smooth arc surfaces, which can play a guiding role during installation. On the one hand, it improves the connection strength between the first protruding ring 2, the second protruding ring 3 and the support ring body 1, and prevents the protruding rings from falling off due to force during installation or use. On the other hand, the smooth arc surface can reduce the frictional resistance between the protruding rings and the piston body mounting holes during installation, guide the support rings to smoothly enter the preset installation position, and reduce the scratch damage to the surface of the components during installation. The metal positioning ring 4 is made of high-strength metal material, which can effectively suppress the deformation of the support ring body 1 during use and ensure the overall performance of the support ring. Utilizing the excellent deformation resistance of the high-strength metal material, it provides a rigid support skeleton for the support ring body 1. When the support ring body 1 is subjected to piston vibration or pressure impact, the metal positioning ring 4 can directly offset part of the external force and prevent the support ring body 1 from bending, twisting or other deformations, ensuring that the support ring always maintains the preset structural shape and ensuring its stable positioning and support performance for the piston body. Multiple second protruding rings 3 are evenly distributed along the circumference of the support ring body 1, which can enhance the positioning stability of the support ring and the mounting part, avoid displacement after installation, and make the second protruding rings 3 form a uniform radial support force on the middle of the support ring body 1. This ensures that the contact surface between the support ring and the piston body mounting part is subjected to balanced force, preventing the support ring from shifting circumferentially during piston movement due to the lack of local support points. This further improves the positioning stability of the support ring and reduces abnormal friction and noise caused by displacement.

[0022] Working principle: During installation, the support ring, relying on the seamless, open structure of the main body 1, and guided by the smooth arc surfaces of the outer walls of the first protruding ring 2 and the second protruding ring 3, directly and precisely aligns with the connecting parts of the multi-segment split piston body. This eliminates the need for elastic deformation or additional adjustments, enabling convenient installation. After installation, the thicker first protruding ring 2 secures itself to the end of the piston body mounting groove, providing reliable axial positioning. Multiple second protruding rings 3, evenly distributed around the circumference of the main body 1, enhance the central positioning, preventing the support ring from shifting. During use, the carbon fiber support ring main body... 1. The reciprocating motion load of the piston body is reduced, and the friction loss with the inner wall of the piston body is reduced. The embedded metal positioning ring 4, with its high-strength material properties, fits tightly with the inner wall of the support ring body 1 without relative displacement, providing rigid support for the support ring body 1, dispersing the radial extrusion force generated by the piston body movement, and preventing the support ring body 1 from denting, bulging or twisting. The overall structure works together to maintain the roundness stability of the support ring, ensuring that it always fits evenly with the inner wall of the piston body, ensuring smooth piston movement, reducing abnormal friction and noise, and adapting to the long-term continuous operation requirements of petrochemical equipment.
