Description

Technical Field

[0001] This application relates to the field of thin oil pumps, and in particular to a thin oil pump hanger. Background Technology

[0002] Thin oil lubrication systems play a crucial role in industrial equipment, widely used in metallurgy, machinery manufacturing, and other fields. However, existing thin oil pumps often connect pressure regulating valves or pressure relief valves to the mounting base via pipelines. The mounting base and valve seat are separate, making assembly difficult. The thin oil pump occupies a large space, and the pipeline connecting the mounting base and valve seat is long, complex, and prone to leaks. Furthermore, when the pump stops working, the pipeline experiences significant pressure due to residual pressure or actuator load. Traditional thin oil pumps often use combination valves or manual air vents to address this, but these can lead to continuous lubricant loss and air ingress into the pipeline, affecting the pump's normal operation. Therefore, the structure of this device needs further improvement. Summary of the Invention

[0003] In order to reduce the size of the device, reduce the difficulty of assembly, and prevent air from entering the pipeline during gas discharge, this application provides a thin oil pump hanger.

[0004] This application provides a thin oil pump support, which adopts the following technical solution:

[0005] A thin oil pump mounting bracket includes a mounting bracket frame. The inner side wall of the mounting bracket frame has an oil inlet channel, and the outer side wall of the mounting bracket frame has a four-way connector. The four-way connector includes a first connecting pipe, a second connecting pipe, and a third connecting pipe. A cavity is formed inside the four-way connector. The first connecting pipe is fixed to the mounting bracket frame. One end of the oil inlet channel is connected to the first connecting pipe and is connected to the cavity. The second connecting pipe is connected to a pressure regulating valve assembly, and the third connecting pipe is connected to a pressure relief valve assembly.

[0006] By adopting the above technical solution, the pressure regulating valve assembly and the pressure relief valve assembly are compactly set on the hanger frame, so that the hanger integrates oil outlet, pressure regulation and pressure relief into one unit, reducing the space occupied by the thin oil pump. Moreover, the pressure regulating valve assembly and the pressure relief valve assembly are directly connected to the four-way connector on the hanger frame, reducing pipeline assembly and testing, improving sealing performance, optimizing structural design and improving the overall reliability of the system.

[0007] Optionally, the pressure regulating valve assembly includes a pressure regulating valve seat, a pressure regulating chamber is formed inside the pressure regulating valve seat, a pressure regulating connector is provided at one end of the pressure regulating valve seat, the pressure regulating connector is fixed to the second connecting pipe, a pressure regulating channel is formed inside the pressure regulating connector, one end of the pressure regulating channel is connected to the cavity, and the other end of the pressure regulating channel is connected to the pressure regulating chamber.

[0008] By adopting the above technical solution, the pressure regulating connector is directly fixed to the second connecting pipe, which is simple to assemble. The cavity, pressure regulating channel and pressure regulating chamber are interconnected and tightly connected, making the pressure regulation sensitive, stabilizing the pressure inside the pipe and reducing the risk of leakage.

[0009] Optionally, a stepped surface is formed between the pressure regulating channel and the pressure regulating cavity. A pressure regulating plunger is provided in the pressure regulating cavity. One end of the pressure regulating plunger is engaged in the pressure regulating channel. A clearance groove is also provided at one end of the pressure regulating channel near the pressure regulating cavity. A protrusion is provided at the other end of the pressure regulating plunger. The protrusion is limited by the stepped surface between the pressure regulating channel and the pressure regulating cavity. A pressure regulating spring is abutted against the lower side of the protrusion.

[0010] By adopting the above technical solution, one end of the pressure regulating plunger is engaged in the pressure regulating channel, preventing thin oil from leaking out of the pressure regulating channel within the set pressure value. By adjusting the pressure of the pressure regulating spring on the pressure regulating plunger, the pressure inside the pipe can be flexibly adjusted. When the pressure inside the pipe is greater than the set pressure value, the pressure regulating plunger is pushed by the pressure inside the pipe. When the pressure regulating plunger is pushed to the relief groove, the thin oil can leak out from the gap between the relief groove and the pressure regulating plunger and flow along the pressure regulating cavity to another device, effectively preventing the pressure inside the pipe from being too high, and making pressure adjustment easy and convenient.

[0011] Optionally, the pressure regulating valve assembly further includes a pressure regulating screw, which is threaded into the pressure regulating valve seat. The pressure regulating screw has a hollow structure, one end of the pressure regulating spring abuts against the protrusion, and the other end of the pressure regulating spring abuts against the inner wall of the pressure regulating screw.

[0012] By adopting the above technical solution, the pressure inside the pipe can be flexibly adjusted by rotating the pressure adjusting screw to adjust the relative distance between the pressure adjusting screw and the pressure adjusting plunger, thereby changing the compression of the pressure adjusting spring.

[0013] Optionally, the pressure relief valve assembly includes a pressure relief valve seat, a pressure relief chamber is formed inside the pressure relief valve seat, a pressure relief connector is provided at one end of the pressure relief valve seat, the pressure relief connector is fixed to the third connecting pipe, a pressure relief channel is formed inside the pressure relief connector, one end of the pressure relief channel is connected to the cavity, and the other end of the pressure relief channel is connected to the pressure relief chamber.

[0014] By adopting the above technical solution, the pressure relief connector is directly fixed to the third connecting pipe, which is simple to assemble. The cavity, pressure relief channel and pressure relief chamber are interconnected and tightly connected, which facilitates pressure relief and reduces the risk of leakage.

[0015] Optionally, the pressure relief valve seat assembly further includes a sealing sleeve with a through hole, a steel ball inside the pressure relief chamber, a pressure relief spring abutting between the steel ball and the sealing sleeve, an inclined surface forming between the pressure relief channel and the pressure relief chamber, and the other side of the steel ball abutting against the inclined surface.

[0016] By adopting the above technical solution, when the pressure inside the pipe reaches a certain value, the thin oil pushes the steel ball, causing the steel ball to leave the inclined plane. The thin oil flows out from the gap between the steel ball and the inclined plane to complete the pressure relief. After the pressure is balanced, the pressure relief spring pushes the steel ball, causing the steel ball to re-abut against the inclined plane, preventing air from entering the pipeline and affecting the use of the thin oil pump.

[0017] Optionally, the first connecting pipe is also provided with a one-way valve, which abuts against the outlet of the oil inlet channel when not in operation.

[0018] By adopting the above technical solution, the pressure in the cavity is maintained to prevent siphoning or backflow of thin oil in the cavity, while keeping the wall full of thin oil, making it easier to start up next time.

[0019] Optionally, the third connecting pipe is coaxially arranged with the first connecting pipe, the pressure relief connector extends into the cavity, and one end of the pressure relief connector is located near the one-way valve.

[0020] By adopting the above technical solution, when the thin oil pump starts, the thin oil pushes open the one-way valve, causing the one-way valve to abut against the pressure relief connector, preventing the thin oil from flowing out of the pressure relief channel. When the thin oil pump is turned off, the thin oil in the oil inlet channel flows back, creating a pressure difference between the pressure relief channel and the cavity, causing the one-way valve to abut against the outlet of the oil inlet channel, preventing the thin oil in the cavity from flowing out, and connecting the pressure relief channel. The structure is simple, maintaining a stable pressure in the pipeline while ensuring that the thin oil flows out of the oil outlet pipe when the thin oil pump is operating.

[0021] Optionally, the four-way connector may also include an oil outlet pipe.

[0022] By adopting the above technical solution, the oil outlet pipe, pressure regulating valve and pressure relief valve are close to each other, reducing the volume occupied by the device, making the structure compact and reducing energy consumption.

[0023] Optionally, the hanger frame is equipped with an oil extraction device, which is used to pressurize oil into the oil inlet.

[0024] By adopting the above technical solution, the oil pumping device pressurizes the thin oil into the oil inlet channel and flows to the oil outlet pipe to complete the transportation of the thin oil.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The pressure regulating valve assembly and the pressure relief valve assembly are compactly mounted on the hanger frame, so that the hanger integrates oil outlet, pressure regulation and pressure relief into one unit, reducing the space occupied by the thin oil pump;

[0027] 2.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] This application discloses a thin oil pump hanger.

[0039] Reference Figures 1 to 3A thin oil pump support includes a support frame 10, which is vertically arranged. An oil inlet channel 11 is formed on the inner side wall of the support frame 10, with one end leading to the bottom of the support frame 10. An oil inlet 12 is formed at the bottom of the support frame 10, communicating with the oil inlet channel 11. A four-way connector 20 is provided on the outer side wall of the support frame 10. The support frame 10 and the four-way connector 20 are integrally formed to improve the overall reliability of the system. The four-way connector 20 includes a first connecting pipe 21, a second connecting pipe 22, and a third connecting pipe 23. The first connecting pipe 21 is fixed to the support frame 10. A cavity 25 is formed inside the head 20. The oil inlet channel 11 is connected to the cavity 25. The other end of the oil inlet channel 11 is connected to the first connecting pipe 21. The second connecting pipe 22 is connected to the pressure regulating valve assembly 30, and the third connecting pipe 23 is connected to the pressure relief valve assembly 40. The pressure regulating valve assembly 30 and the pressure relief valve assembly 40 are compactly arranged on the hanger frame 10, so that the hanger integrates oil outlet, pressure regulation and pressure relief into one unit, reducing the space occupied by the thin oil pump. Moreover, the pressure regulating valve assembly 30 and the pressure relief valve assembly 40 are directly connected to the four-way connector 20 on the hanger frame 10, reducing pipeline assembly, improving sealing performance and optimizing structural design.

[0040] Reference Figures 1 to 5 The pressure regulating valve assembly 30 includes a pressure regulating valve seat 31, a pressure regulating chamber 33 is formed inside the pressure regulating valve seat 31, and a pressure regulating connector 32 is provided at one end of the pressure regulating valve seat 31. The outer wall of the pressure regulating connector 32 abuts against the second connecting pipe 22, making assembly simple. A pressure regulating channel 34 is formed inside the pressure regulating connector 32. One end of the pressure regulating channel 34 is connected to the cavity 25, and the other end of the pressure regulating channel 34 is connected to the pressure regulating chamber 33. The cavity 25, the pressure regulating channel 34, and the pressure regulating chamber 33 are interconnected and tightly connected, which can sensitively stabilize the pressure inside the pipe. The pressure regulating valve and the hanger 10 do not need to be connected by pipes, reducing the risk of leakage.

[0041] The inner diameter of the pressure regulating channel 34 is smaller than the inner diameter of the pressure regulating cavity 33. A stepped surface 35 is formed between the pressure regulating channel 34 and the pressure regulating cavity 33. A pressure regulating plunger 37 is provided in the pressure regulating cavity 33. One end of the pressure regulating plunger 37 is engaged in the pressure regulating channel 34 to prevent thin oil from leaking out of the pressure regulating channel 34 within the set pressure value. A relief groove 341 is also provided at the end of the pressure regulating channel 34 near the pressure regulating cavity 33. A protrusion 371 is provided on the outer wall of the pressure regulating plunger 37. The protrusion 371 is located at the end of the pressure regulating plunger 37 away from the pressure regulating channel 34. The protrusion 371 passes through the stepped surface 35 between the pressure regulating channel 34 and the pressure regulating cavity 33. The stepped surface 35 is used for limiting, and the lower side of the protrusion 371 abuts against the pressure regulating spring 38. The other end of the pressure regulating plunger 37 is used to limit the pressure regulating spring 38. By adjusting the pressure of the pressure regulating spring 38 on the pressure regulating plunger 37, the pressure inside the pipe can be flexibly adjusted. When the pressure inside the pipe is greater than the set pressure value, the pressure regulating plunger 37 is pushed by the pressure inside the pipe. When the pressure regulating plunger 37 is pushed to the relief groove 341, the thin oil can leak out from the gap between the relief groove 341 and the pressure regulating plunger 37 and flow along the pressure regulating cavity 33 to another device, effectively preventing the pressure inside the pipe from being too high, and easily and conveniently adjusting the pressure inside the pipe as needed.

[0042] The pressure regulating valve assembly 30 also includes a pressure regulating screw 36. The end of the pressure regulating screw 36 is threaded into the pressure regulating valve seat 31, and the upper end of the pressure regulating screw 36 abuts against the inner wall of the pressure regulating chamber 33 to prevent thin oil leakage. The pressure regulating screw 36 has a hollow structure, allowing the pressure regulating chamber 33 to communicate with the outside. The inner wall of the end of the pressure regulating screw 36 protrudes to form an abutment position 361. One end of the pressure regulating spring 38 abuts against the protrusion 371, and the other end of the pressure regulating spring 38 abuts against the abutment position 361. By simply adjusting the position of the pressure regulating screw 36, the pressure regulating spring 38 undergoes different degrees of elastic deformation, thereby forming different pressure regulating pressures. The opening pressure of the pressure regulating valve can be easily and conveniently adjusted, effectively preventing excessive pressure in the pipe and reducing safety hazards.

[0043] Reference Figure 1 and Figure 6 The pressure relief valve assembly 40 includes a pressure relief valve seat 41, a pressure relief chamber 43 is formed inside the pressure relief valve seat 41, and a pressure relief connector 42 is provided at one end of the pressure relief valve seat 41. The pressure relief connector 42 is snapped into the inner wall of the third connecting pipe 23, which is simple to assemble. A pressure relief channel 44 is formed inside the pressure relief connector 42. One end of the pressure relief channel 44 is connected to the cavity 25, and the other end of the pressure relief channel 44 is connected to the pressure relief chamber 43. The cavity 25, the pressure relief channel 44 and the pressure relief chamber 43 are interconnected and tightly connected, which facilitates pressure relief and reduces the risk of leakage.

[0044] The pressure relief valve seat 41 assembly also includes a sealing sleeve 46, which has a through hole 461 to connect the pressure relief valve seat 41 to the cavity 25 and the external environment. The inner diameter of the pressure relief channel 44 is smaller than the inner diameter of the pressure relief chamber 43. An inclined surface 45 is formed between the pressure relief channel 44 and the pressure relief chamber 43. A steel ball 47 is provided in the pressure relief chamber 43. A pressure relief spring 48 abuts between the steel ball 47 and the sealing sleeve 46. The pressure relief spring 48 is compressed. The pressure relief spring 48 presses the other side of the steel ball 47 against the inclined surface 45. When the pressure in the pipe reaches a certain value, the thin oil pushes the steel ball 47, causing the steel ball 47 to leave the inclined surface 45. The thin oil flows out from the gap between the steel ball 47 and the inclined surface 45 to complete the pressure relief. After the pressure is balanced, the pressure relief spring 48 pushes the steel ball 47, causing the steel ball 47 to abut against the inclined surface 45 again, so as to prevent air from entering the pipeline and affecting the use of the thin oil pump.

[0045] Reference Figure 3 The first connecting pipe 21 is also equipped with a one-way valve 26. In the non-working state, the one-way valve 26 abuts against the outlet of the oil inlet channel 11 to maintain the pressure in the cavity 25, prevent siphoning or backflow of thin oil in the cavity 25 as much as possible, and keep the wall full of thin oil, making it easier to start next time.

[0046] Reference Figures 1 to 3 The third connecting pipe 23 is coaxially arranged with the first connecting pipe 21. The pressure relief connector 42 extends into the cavity 25, with one end of the pressure relief connector 42 positioned near the one-way valve 26. When the thin oil pump starts, the thin oil pushes open the one-way valve 26, causing the one-way valve 26 to abut against the pressure relief connector 42, preventing the thin oil from flowing out of the pressure relief channel 44. When the thin oil pump stops, the thin oil in the oil inlet channel 11 flows back, creating a pressure difference between the pressure relief channel 44 and the cavity 25, causing the one-way valve 26 to abut against the outlet of the oil inlet channel 11, preventing the thin oil from flowing out of the cavity 25, and connecting the pressure relief channel 44. The structure is simple, maintaining a stable pressure in the pipeline while preventing the thin oil from flowing out of the pressure relief channel 44 as much as possible when the thin oil pump is operating. In this embodiment, the third connecting pipe 23 and the first connecting pipe 21 are arranged horizontally, and the second connecting pipe 22 is arranged vertically with its opening facing downwards.

[0047] Reference Figure 1 and Figure 3 The four-way connector 20 also includes an oil outlet pipe 24. The axis of the oil outlet pipe 24 is perpendicular to the axis of the first connecting pipe 21, the axis of the second connecting pipe 22 and the axis of the third connecting pipe 23, respectively. The port of the oil outlet pipe 24 is connected to the cavity 25. The oil outlet pipe 24, the pressure regulating valve and the pressure relief valve are close to each other, reducing the volume occupied by the device, making the structure compact and reducing energy consumption.

[0048] The hanging bracket 10 is equipped with an oil pumping device, which is used to press oil into the oil inlet 12. The oil pumping device presses the thin oil into the oil inlet channel 11 and flows to the oil outlet pipe 24 to complete the transportation of the thin oil.

[0049] The implementation principle of a thin oil pump holder in this embodiment is as follows: The oil pumping device draws thin oil from the oil inlet 12 into the oil inlet channel 11. After the thin oil reaches the opening of the first connecting pipe 21, it opens the one-way valve 26. At this time, the one-way valve 26 abuts against the end of the pressure relief connector 42, closing the pressure relief channel 44 and preventing the thin oil from overflowing from the pressure relief channel 44. After the thin oil flows into the cavity 25 from the oil inlet channel 11, it flows to the required device from the oil outlet pipe 24. When the pressure inside the pipe is too high, the pressure of the thin oil on the pressure regulating plunger 37 is greater than the pressure of the pressure regulating spring 38 on the pressure regulating plunger 37. The thin oil pushes the pressure regulating plunger 37 downward until the upper end of the pressure regulating plunger 37 retracts to the relief groove 341. At this time, the thin oil can flow out from the gap between the pressure regulating plunger 37 and the relief groove 341 to maintain the pressure inside the pipe and prevent the pressure inside the pipe from being too high. When the adjusting screw is rotated to move it upwards, the compression deformation of the adjusting spring 38 increases, and the pressure of the adjusting spring 38 on the adjusting plunger 37 also increases, which can maintain a larger pressure in the pipe; when the adjusting screw is rotated to move it downwards, the compression deformation of the adjusting spring 38 decreases, and the pressure of the adjusting spring 38 on the adjusting plunger 37 also decreases, which can maintain a smaller pressure in the pipe. When the oil pumping device is turned off, the thin oil stops being pumped into the oil inlet channel 11. At this time, due to the pressure difference between the cavity 25 and the oil inlet channel 11, the pressure pushes the one-way valve 26 to the port of the first connecting pipe 21, sealing the oil inlet channel 11 and preventing the thin oil from flowing out of the oil inlet channel 11. At the same time, the one-way valve 26 leaves the pressure relief connector 42, making the cavity 25 connected to the pressure relief channel 44. When the residual pressure in the cavity 25 is too high, the thin oil overcomes the thrust of the pressure relief spring 48 and pushes the steel ball 47 away, allowing the thin oil to flow out from the pressure relief chamber 43 to balance the pressure in the pipe. After pressure relief, the pressure relief spring 48 returns to its original position, pushing the steel ball 47 towards the pressure relief channel 44 to seal the pressure relief channel 44 and prevent the thin oil from continuously flowing out, causing air bubbles to enter the pipeline.

[0050] The above are all preferred embodiments of this application. These embodiments are only 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.
