Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, and in particular to a grease pump hanger. Background Technology

[0002] In numerous industrial production and machinery operation scenarios, oil pumps play a crucial role in ensuring the normal operation of equipment. However, traditional grease pump mounts have gradually revealed many limitations in practical applications. Existing mounts often have relatively simple functions, merely providing support and connection, and lack the ability to effectively regulate parameters such as oil pump pressure. Therefore, a grease pump mount with pressure regulation capabilities is needed. Utility Model Content

[0003] In order to improve the pressure regulation performance of the grease pump hanger, this application provides a grease pump hanger.

[0004] The grease pump hanger provided in this application adopts the following technical solution: A grease pump support includes a support body, an oil passage within the support body, an oil inlet and an oil outlet, the two ends of the oil passage being connected to the oil inlet and the oil outlet respectively, a pressure regulating port connected to the end of the oil passage near the oil inlet, a pressure regulating valve being provided at the pressure regulating port, and a pressure relief port provided to the end of the oil passage near the oil outlet, a pressure relief valve being provided at the pressure relief port.

[0005] By adopting the above technical solution, an oil passage is set in the body of the grease pump holder, and a pressure regulating valve and a pressure relief valve are set in the pressure regulating port and the pressure relief port, so as to realize the pressure regulation and pressure relief control of the oil flowing in the oil passage, ensuring that the oil pressure is stable and reasonable throughout the entire transportation process, and ensuring the reliability of the grease pump holder and the smoothness of oil transportation.

[0006] Optionally, the pressure regulating valve includes a pressure regulating valve seat, which has a pressure regulating space and a pressure regulating channel. The pressure regulating space, the pressure regulating channel, and the pressure regulating port are connected in sequence. A pressure regulating component is provided in the pressure regulating space. The pressure regulating component is used to change the opening size of the pressure regulating channel. The pressure regulating component has a return channel.

[0007] By adopting the above technical solution, the pressure regulating valve can flexibly control the pressure threshold in the oil passage by changing the opening size of the pressure regulating channel through the pressure regulating component, thereby meeting the pressure requirements under different operating conditions. The connection structure between the pressure regulating space, the pressure regulating channel, and the pressure regulating port, together with the return channel of the pressure regulating component, allows oil exceeding the pressure threshold to be guided back through the return channel, avoiding pressure fluctuations from impacting the system, achieving dynamic pressure balance, and improving pressure regulation accuracy and reliability.

[0008] Optionally, the pressure regulating assembly includes a pressure regulating screw, a compression spring, and a steel ball. The pressure regulating screw is located on the side of the pressure regulating space away from the pressure regulating channel. The pressure regulating screw is threaded to the inner wall of the pressure regulating valve seat. The pressure regulating screw passes through and forms the return channel. The steel ball is located at the opening of the pressure regulating channel. The two ends of the compression spring are connected to the pressure regulating screw and the steel ball, respectively.

[0009] By adopting the above technical solution, the sealing force of the steel ball on the pressure regulating channel can be precisely controlled by rotating the pressure adjusting screw to change the spring preload, achieving stepless pressure adjustment. This method is convenient to operate and offers high adjustment accuracy. The oil overcomes the force of the compressed spring, pushing the steel ball back through the return channel, forming a closed-loop pressure regulation mechanism, further enhancing the system's pressure stability.

[0010] Optionally, the pressure relief valve includes a pressure relief valve seat with a pressure relief space; the oil passage includes a first oil passage and a second oil passage, the oil inlet is located in the first oil passage, and the oil outlet is located in the second oil passage, the first oil passage, the pressure relief port, the pressure relief space, and the second oil passage are sequentially connected; a pressure relief component is provided in the pressure relief space, the pressure relief component is slidably connected to the pressure relief port, and the pressure relief component has a pressure relief channel.

[0011] By adopting the above technical solution, the oil passage is divided into a first oil passage and a second oil passage, which are connected to the pressure relief space through a pressure relief port, allowing the pressure relief component to directly respond to changes in oil passage pressure. When the oil viscosity exceeds a set value, the pressure relief component slides to close the pressure relief channel, allowing the oil to flow from the first oil passage through the pressure relief port and the pressure relief space into the second oil passage. When the viscosity is insufficient, the pressure relief component cannot slide to close the pressure relief channel, and no pressure can be formed in the oil passage, causing the oil to flow out through the pressure relief channel.

[0012] Optionally, the pressure relief assembly includes a pressure relief connector, a pressure relief spring, and an umbrella valve. The umbrella valve is slidably connected to the inner wall of the pressure relief valve seat and located at the pressure relief port. The pressure relief connector is fixedly connected to the pressure relief valve seat and located in the pressure relief space on the side away from the pressure relief port. The pressure relief connector has a pressure relief channel. The umbrella valve has a plug on the side near the pressure relief channel. The two ends of the pressure relief spring are respectively connected to the pressure relief connector and the umbrella valve. The umbrella valve has a skirt around its periphery. The radius of the skirt gradually increases along the direction from the pressure relief port to the pressure relief channel. The skirt abuts against the inner wall of the pressure relief valve seat.

[0013] By adopting the above technical solution, when the oil viscosity exceeds the set value, the oil pushes the umbrella valve to slide against the spring force, the umbrella valve leaves the pressure relief port and closes the pressure relief channel, the pressure relief port opens, and the oil flows to the second oil passage through the pressure relief space; when the oil viscosity is insufficient, the spring pushes the umbrella valve to reset, and at the same time the pressure relief channel opens, pressure cannot be formed in the oil passage, and the oil flows out from the pressure relief channel.

[0014] Optionally, the oil passage has a third oil passage, which is vertically arranged on one side of the oil outlet and is connected to the outside.

[0015] By adopting the above technical solution, during normal operation, the oil flows out through the oil outlet. When the pressure in the oil passage is too high and the oil outlet reaches the maximum flow rate, the oil can overcome gravity and rise in the third oil passage. The third oil passage provides additional buffer pressure space for the oil passage.

[0016] Optionally, the third oil passage is connected to a pressure switch interface, which is equipped with a pressure switch for changing the opening size of the third oil passage.

[0017] By adopting the above technical solution, the pressure switch can automatically change the size of the third oil passage opening according to the actual oil passage pressure. When the pressure rises abnormally, the pressure switch can increase the opening to enhance the pressure relief and buffering capacity of the third oil passage, avoiding a sudden increase in pressure when the oil outlet flow is saturated; when the pressure returns to the normal range, it can reduce the opening to reduce unnecessary oil loss, or choose to close the third oil passage.

[0018] Optionally, the oil passage near the oil inlet is also connected to an exhaust valve interface, and the exhaust valve interface is equipped with an exhaust valve.

[0019] By adopting the above technical solution and installing an air vent valve near the oil inlet, air in the oil passage can be quickly expelled during the initial oil injection, preventing pressure fluctuations and delivery interruptions caused by cavitation. Pre-venting ensures a continuous and stable liquid flow after the oil enters the oil passage, reducing the impact and wear of air bubbles on precision components such as the pressure regulating valve and pressure relief valve. It also improves the initial start-up efficiency of the entire system and shortens equipment commissioning time.

[0020] In summary, this application includes at least one of the following beneficial effects: 1. By installing pressure regulating and pressure relief valves on the oil passages, the pressure regulating component can achieve stepless pressure adjustment, and the pressure relief component can automatically switch the oil flow direction according to pressure changes. Combined with the pressure buffering and active adjustment functions of the third oil passage and pressure switch, a complete pressure control mechanism is formed. This ensures that the oil maintains a stable and reasonable pressure state during transportation, regardless of pressure changes under different operating conditions or situations such as abnormal pressure increases and flow saturation. It effectively avoids transportation interruptions caused by pressure fluctuations and damage to pipelines and equipment, ensuring the smoothness and stability of oil transportation.

[0021] 2. By utilizing the pressure relief assembly consisting of an umbrella valve and a pressure relief spring in the pressure relief valve, as well as the return flow channel design of the pressure regulating valve, pressure can be relieved and returned in a timely manner in the event of overpressure, preventing excessive pressure from impacting the entire system. Simultaneously, the air vent valve discharges air during the initial oil injection, reducing the impact and wear of air bubbles on precision components such as the pressure regulating valve and pressure relief valve, lowering the probability of component failure, extending the service life of each component, and improving the overall reliability of the grease pump mount. This reduces the frequency of maintenance and component replacement, and lowers operating costs. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a grease pump hanger. (Refer to...) Figure 1-5 The system includes a suspension body 1, an oil passage 2 inside the suspension body 1, a pressure relief port 202, a pressure relief valve 4 at the pressure relief port 202, and a pressure relief space 4101. The oil passage 2 includes a first oil passage 21 and a second oil passage 22. The first oil passage 21 is connected to an oil inlet 101, and the second oil passage 22 is connected to an oil outlet 102. The oil inlet 101, the first oil passage 21, the pressure relief port 202, the pressure relief space 4101, the second oil passage 22, and the oil outlet 102 are connected in sequence. A pressure relief assembly 42 is provided in the pressure relief space 4101. The pressure relief assembly 42 includes a pressure relief connector 421, a pressure relief spring 422, and an umbrella valve 423. The umbrella valve 423 is slidably connected to the inner wall of the pressure relief valve seat 41 and is located at the pressure relief port 202. The pressure relief connector 421 is fixedly connected to the pressure relief valve seat 41 and is connected to the umbrella valve 423 by the pressure relief spring 422. The pressure relief connector 421 has a pressure relief channel 4201 that is open through it and is connected to the outside. The umbrella valve 423 includes a plug 4231 and a skirt 4232. The plug 4231 is correspondingly provided to the pressure relief channel 4201. The skirt 4232 is arranged around the plug 4231. The radius of the skirt 4232 gradually increases along the direction from the pressure relief port 202 to the pressure relief channel 4201. The skirt 4232 abuts against the inner wall of the pressure relief valve seat 41. Specifically, in this embodiment, the material of the hanging bracket body 1 is cast aluminum alloy. The hanging bracket body 1 made of cast aluminum alloy has low density while ensuring strength, and is lightweight and easy to install and disassemble. The hanging bracket body 1 made of cast aluminum also has good corrosion resistance and thermal conductivity. The dense oxide film formed on the surface can block external corrosive substances, and the good thermal conductivity can conduct and dissipate the heat of the grease in a timely manner, maintaining a stable temperature.

[0031] When the viscosity of the oil in oil passage 2 reaches a certain level, the oil, under the pressure of the oil pump, can overcome the elastic force of the pressure relief spring 422 to push the umbrella valve 423. The plug 4231 of the umbrella valve 423 contacts the pressure relief connector 421 and closes the pressure relief channel 4201. The pressure relief space 4101 is sealed, and internal pressure is built up in oil passage 2. The oil can flow from the inlet 101 through oil passage 2 to the outlet 102. When the viscosity of the oil is not high enough to push the umbrella valve 423, the plug 4231 cannot contact the pressure relief connector 421, the pressure relief channel 4201 connects the pressure relief space 4101 and the outside, and a closed oil circuit cannot be formed in the hanger. The oil will flow out from the pressure relief channel 4201. Specifically, the skirt 4232 is made of elastic rubber. When the oil passage cannot be formed, the oil is pressured by the oil pump and enters the pressure relief space 4101 from the pressure relief port 202. It will flow into the pressure relief channel 4201 through the gap between the skirt 4232 and the pressure relief valve seat 41. At this time, under the pressure of the oil, the elastic skirt 4232 will repeatedly hit the inner wall of the pressure relief valve seat 41 and make an abnormal noise. The staff can judge whether the viscosity of the oil meets the standard by the abnormal noise.

[0032] In a preferred embodiment, refer to Figure 1 and 6 The first oil passage 21 is connected to a pressure regulating port 201 at one end near the oil inlet 101. A pressure regulating valve 3 is installed at the pressure regulating port 201. The pressure regulating valve 3 includes a pressure regulating valve seat 31 and a pressure regulating assembly 32. The pressure regulating valve seat 31 has a pressure regulating space 3101 and a pressure regulating channel 3102. The pressure regulating space 3101, the pressure regulating channel 3102, and the pressure regulating port 201 are connected in sequence. The pressure regulating assembly 32 includes a pressure regulating screw 321, a compression spring 322, and a steel ball 323. The two ends of the compression spring 322 are connected to the pressure regulating screw 321 and the steel ball 323, respectively. The steel ball 323 is located in the pressure regulating channel 3102 and within the pressure regulating space 3101. The pressure regulating screw 321 is located on the side of the pressure regulating space 3101 away from the pressure regulating channel 3102. The pressure regulating screw 321 is threadedly connected to the inner wall of the pressure regulating valve seat 31. Specifically, an adjusting nut is fitted onto the adjusting screw 321, which is used to fix the position of the adjusting screw 321 on the adjusting valve seat 31. A return channel 3201 is provided through the adjusting screw 321. By rotating the adjusting screw 321 to change the spring preload, the sealing force of the steel ball 323 on the adjusting channel 3102 can be precisely controlled, achieving stepless pressure adjustment. This method is convenient to operate and offers high adjustment accuracy. The oil overcomes the force of the compression spring 322, pushing the steel ball 323 back through the return channel 3201. The returned oil can then re-enter the oil passage 2 through the oil inlet 101, forming a closed-loop pressure regulation mechanism and further enhancing the system's pressure stability.

[0033] In a preferred embodiment, refer to Figure 4The second oil passage 22 is connected to the third oil passage 23, which is vertically arranged on one side of the oil outlet 102 and is connected to the outside. During normal operation, the oil flows out through the oil outlet 102. When the pressure inside the oil passage 2 is too high and the oil outlet 102 reaches its maximum flow rate, the oil can overcome gravity and rise in the third oil passage 23. The third oil passage 23 provides additional pressure buffer space for the oil passage 2.

[0034] In a preferred embodiment, refer to Figure 4 The third oil passage 23 is connected to a pressure switch interface 203, which is equipped with a pressure switch 5. The pressure switch 5 is used to change the opening size of the third oil passage 23. The pressure switch 5 can automatically change the opening size of the third oil passage 23 according to the actual pressure of the oil passage 2. When the pressure rises abnormally, the pressure switch 5 can increase the opening to increase the pressure relief and buffering capacity of the third oil passage 23 and avoid a sudden increase in pressure when the flow at the oil outlet 102 is saturated; when the pressure returns to the normal range, it can reduce the opening to reduce unnecessary oil loss, or choose to close the third oil passage 23.

[0035] In a preferred embodiment, refer to Figure 1 The end of oil passage 2 near the oil inlet 101 is also connected to an exhaust valve interface 204, which is equipped with an exhaust valve (not shown in the figure). The exhaust valve is a device used in the prior art to discharge gas from the pipeline, and will not be described in detail here. The exhaust valve can quickly discharge air in oil passage 2 at the initial stage of oil injection, preventing pressure fluctuations and interruption of delivery caused by cavitation. Early venting ensures that the oil forms a continuous and stable liquid flow after entering oil passage 2, reduces the impact and wear of air bubbles on precision components such as pressure regulating valve 3 and pressure relief valve 4, and improves the initial start-up efficiency of the entire system, shortening the equipment commissioning time.

[0036] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
