Description

Technical Field

[0001] This application relates to the technical field of oil and gas gathering and transportation equipment, and in particular to a non-stop oil replenishment system for hydraulic oil tanks of compressor units. Background Technology

[0002] In oil and gas gathering and transportation systems, the hydraulic system of the compressor unit serves as the core power transmission unit, relying on hydraulic oil to achieve key functions such as energy transfer, component lubrication, sealing protection, and system cooling.

[0003] Traditional oil replenishment processes are limited by the tank structure design and must follow a rigid procedure of shutdown, system depressurization, atmospheric pressure oil replenishment, and start-up and commissioning. Specifically, the hydraulic system maintains working pressure inside the tank during operation. If the depressurization unit cannot open the injection valve, fuel gas cannot enter, and the equipment cannot operate normally. Therefore, it is necessary to shut down the power source and then reduce the system pressure to atmospheric pressure through the vent valve. Actual measurement data shows that a single oil replenishment operation takes half an hour under standard operating conditions. In winter operating conditions below -30 degrees Celsius, the viscosity of hydraulic oil increases to three to five times that at room temperature. When starting up, additional oil preheating and system venting are required, extending the total time for a single oil replenishment by one hour and thirty minutes, which seriously affects the continuity of the gathering and transportation system.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a drawback in that it is necessary to stop the machine and add fluid. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a non-stop oil replenishment system for the hydraulic oil tank of a compressor unit.

[0006] This application provides a non-stop oil replenishment system for the hydraulic oil tank of a compressor unit, which adopts the following technical solution: A non-stop oil replenishment system for a compressor unit's hydraulic oil tank includes an air source device, an oil supply pipeline, an air source pipeline, a main tank, and an auxiliary tank. The auxiliary tank is installed on top of the main tank. An oil inlet is provided on one side of the main tank, and an oil replenishment port is provided on one side of the auxiliary tank. The two ends of the oil supply pipeline are fixedly connected to the oil inlet and the oil replenishment port, respectively. A main-auxiliary tank connecting valve is provided on the oil supply pipeline. A first air source inlet is provided on the other side of the main tank, and a second air source inlet is provided on the other side of the auxiliary tank. The air source pipeline is a three-way pipeline with an air inlet, a first air outlet, and a second air outlet. The air source device is fixedly connected to the air inlet, the first air outlet is fixedly connected to the first air source inlet, and the second air outlet is fixedly connected to the second air source inlet. A first air source pressure equalization valve is provided on the air source pipeline near the first air outlet, and a second air source pressure equalization valve is provided on the air source pipeline near the second air outlet.

[0007] By adopting the above technical solution, the limitations of the traditional single-tank structure are overcome. The main tank and auxiliary tank are connected in an upper and lower tank configuration. The connection between the auxiliary tank and the main tank establishes a pressure difference to drive the oil pipeline. When the first air source equalization valve and the main-auxiliary tank connection valve are opened, the auxiliary tank is depressurized and forms a pressure gradient with the main tank, driving hydraulic oil to be added through the oil pipeline without stopping the machine. When the main oil is added to the required position, the main-auxiliary tank connection valve is closed, and the first air source equalization valve and the second air source equalization valve remain open to maintain the same air source pressure on the main tank and auxiliary tank, avoiding pressure difference from damaging system stability and solving the safety hazards of pressurized oil replenishment in traditional processes. Before replenishing the auxiliary tank, it is necessary to ensure that the first air source equalization valve and the main-auxiliary tank connection valve are closed, disconnect the physical connection between the auxiliary tank and the main tank and the air source device, open the pressure relief valve on the top of the auxiliary tank to release the residual pressure in the auxiliary tank, and open the auxiliary tank to add oil after the internal pressure of the auxiliary tank reaches atmospheric pressure.

[0008] Preferably, the oil inlet is located at one-half the height of the middle part of one side of the main tank, and the first gas source inlet is located at one-eighth the height of the upper part of the main tank.

[0009] By adopting the above technical solution, the oil replenishment inlet is opened at the middle half height. According to the principle of fluid mechanics, this position is at the static pressure center of the tank, which can ensure that the fluid is evenly distributed during oil replenishment. The fuel gas inlet is opened at the upper one-eighth height. This position is far away from the oil interface, which can prevent oil from entering the gas system during oil replenishment.

[0010] Preferably, the auxiliary tank is provided with a viewing window interface, which is located at one-third of the height of the lower part of the auxiliary tank, and the oil replenishment port on the auxiliary tank is located at one-eighth of the height of the bottom.

[0011] By adopting the above technical solution, the viewing window interface is located at the lower third of the height. According to the liquid level observation requirements, this position can cover most of the normal working liquid level range. The oil replenishment outlet is opened at the bottom one-eighth of the height, and the liquid level difference is used to form the oil replenishment power.

[0012] Preferably, the viewing window interface is provided with an oil level viewing window for observing the oil level inside the auxiliary tank, and the oil level viewing window is fixedly connected to the viewing window interface.

[0013] Preferably, the top of the auxiliary tank is provided with a pressure relief valve for reducing the internal pressure of the auxiliary tank, the pressure relief valve is fixedly connected to the auxiliary tank, and the middle part of the top of the auxiliary tank is provided with a filling port, the filling port is provided with a filling plug, and the filling plug is detachably connected to the filling port.

[0014] By adopting the above technical solution, the pressure relief valve can actively release excess pressure inside the auxiliary tank and accurately control the pressure between the auxiliary tanks. The oil filling port provides a dedicated channel for replenishing hydraulic oil to the auxiliary tank. Operators can directly add oil to the auxiliary tank through the oil filling port without disassembling other parts, simplifying the preparation process before oil replenishment.

[0015] Preferably, the main tank is equipped with a level gauge for detecting the oil level inside the main tank, and the level gauge is detachably connected to the main tank.

[0016] By adopting the above technical solution, the level gauge can directly reflect the oil position inside the main tank and monitor the hydraulic oil level in the main tank in real time. When the oil level is lower than the normal operating threshold, the auxiliary tank oil replenishment process can be started in time to avoid insufficient oil supply to the compressor unit hydraulic system due to the low oil level in the main tank.

[0017] Preferably, the lower part of the main tank is provided with multiple sets of outlets, and multiple sets of injection valves and multiple sets of exhaust resistance valves are provided on the outlets. The injection valves are fixedly connected to one end of the outlets, and the exhaust resistance valves are installed at the outlets and fixedly connected to the outlets.

[0018] By adopting the above technical solution, after starting the unit, it is necessary to monitor the ignition status of each cylinder. If an ignition abnormality occurs, it indicates that air has entered the pipeline due to oil replenishment, forming an air blockage. It is necessary to operate the exhaust blockage valve one by one to release the air through the injection valve path until each cylinder restores the normal ignition logic, ensuring the stable operation of the unit's power unit.

[0019] Preferably, the top of the main tank and the bottom of the auxiliary tank are provided with multiple sets of positioning and mounting devices. The positioning and mounting devices include positioning blocks, positioning pins and connecting blocks. The positioning blocks are installed on the main tank and are provided with positioning grooves and a first positioning hole penetrating the positioning blocks. The connecting blocks are installed on the bottom of the auxiliary tank and are provided with a second positioning hole. The connecting blocks and the positioning blocks are detachably connected by positioning pins.

[0020] By adopting the above technical solution, the positioning groove on the positioning block can pre-position the connecting block, ensuring that when the auxiliary tank is installed on top of the main tank, the relative position of the two meets the design requirements, avoiding problems such as misalignment of pipe connections and failure of valves to cooperate properly due to installation deviation. After the positioning pin passes through the first positioning hole of the positioning block and the second positioning hole of the connecting block, it can rigidly fix the main and auxiliary tanks.

[0021] Preferably, a cleaning plug is provided at the oil filling port on the top of the auxiliary tank. The cleaning plug is detachably connected to the oil filling port. The cleaning plug includes a shell, a bearing assembly, a first gear, a second gear, an electric motor, a liquid inlet pipe, a guide pipe, and a high-pressure nozzle. One end of the liquid inlet pipe is fixedly connected to the shell, and the other end of the liquid inlet pipe is installed at the inlet of the guide pipe. The guide pipe is rotatably connected to the liquid inlet pipe. The inner ring of the bearing assembly is installed at the inlet of the guide pipe, and the outer ring of the bearing assembly is installed inside the shell. The first gear is installed on the guide pipe on one side of the bearing assembly. The base of the electric motor is fixedly connected to the inner wall of the shell. The second gear is installed at the working end of the electric motor. The second gear meshes with the first gear to drive the transmission. The electric motor provides rotational power to the guide pipe. The guide pipe is rotatably connected to the shell through the bearing assembly. The other end of the guide pipe is connected to the high-pressure nozzle. The guide pipe is a curved pipe, and the other end of the guide pipe extends into the inner wall of the auxiliary tank along with the high-pressure nozzle.

[0022] By adopting the above technical solution, the cleaning plug integrates a high-pressure nozzle, a guide pipe, and a drive device. Cleaning hydraulic oil is introduced through the inlet pipe and delivered to the high-pressure nozzle via the guide pipe, where it is sprayed at high pressure onto the inner wall of the auxiliary tank. The guide pipe is designed with a curved structure and is driven by an electric motor to mesh with a first and second gear. A bearing device enables the rotation of the guide pipe and the high-pressure nozzle. This rotary spraying method can cover all corners inside the auxiliary tank. The cleaning plug and the filler port are detachably connected; when cleaning is needed, simply remove the original filler plug and replace it with the cleaning plug.

[0023] Preferably, an inlet pipe is provided inside the oil inlet, and the inlet pipe is fixedly connected to the oil inlet. The inlet pipe is a curved pipe that bends downwards along the arc of the inner wall of the main tank.

[0024] By adopting the above technical solution, the downward-curved inlet pipe can use its curvature to buffer the flow rate and impact force of the oil, allowing the oil to flow smoothly along the inner wall of the main tank and gradually merge into the oil in the tank, reducing splashing and agitation, and reducing the mixing of air in the oil. When cleaning hydraulic oil is introduced through the inlet pipe, the downward-curved design that conforms to the curvature of the inner wall of the main tank guides the cleaning hydraulic oil to flow smoothly along the tank wall and spread downward to cover more tank wall areas.

[0025] In summary, this application includes at least one of the following beneficial technical effects: Breaking through the limitations of traditional single-tank structures, this system features an interconnected upper and lower tank architecture for the main and auxiliary tanks. A pressure difference is established between the auxiliary and main tanks to drive the oil supply pipeline. When the first air source equalization valve and the main-auxiliary tank connection valve are opened, the auxiliary tank depressurizes, creating a pressure gradient with the main tank. This drives hydraulic oil through the oil supply pipeline for non-stop replenishment. When the main oil reaches the required level, the main-auxiliary tank connection valve closes, while the first and second air source equalization valves remain open to maintain consistent air source pressure between the main and auxiliary tanks. This prevents pressure differences from disrupting system stability and addresses the safety hazards of pressurized oil replenishment in traditional processes. Before replenishing the auxiliary tank, ensure the first air source equalization valve and the main-auxiliary tank connection valve are closed, disconnect the physical connection between the auxiliary tank and the main tank and air source device, open the pressure relief valve at the top of the auxiliary tank to release residual pressure, and allow the internal pressure of the auxiliary tank to reach atmospheric pressure before opening the auxiliary tank to replenish the oil.

[0026] The cleaning plug integrates a high-pressure nozzle, guide pipe, and drive unit. Cleaning hydraulic oil is connected via an inlet pipe, then delivered to the high-pressure nozzle through the guide pipe, and sprayed at high pressure onto the inner wall of the auxiliary tank. The guide pipe is designed with a curved structure and is driven by an electric motor, which meshes with a first and second gear. A bearing device enables the rotation of the guide pipe and the high-pressure nozzle. This rotary spraying method can cover all corners inside the auxiliary tank. The cleaning plug and the filler port are detachably connected; when cleaning is needed, simply remove the existing filler plug and replace it with the cleaning plug. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a non-stop oil replenishment system for the hydraulic oil tank of a compressor unit. (Refer to...) Figure 1 and Figure 2It includes a gas source device 1, an oil pipeline 2, a gas source pipeline 3, a main tank 4, and an auxiliary tank 5. The auxiliary tank 5 is installed on top of the main tank 4. Multiple positioning and mounting devices 6 are installed on the top of the main tank 4 and the bottom of the auxiliary tank 5. Each positioning and mounting device 6 includes a positioning block 61, a positioning pin 62, and a connecting block 63. The positioning block 61 has a through first positioning hole 612 and a positioning groove 611. The connecting block 63 has a second positioning hole 631. The connecting block 63 is installed in the positioning groove 611. The positioning pin 62 is inserted into the first positioning hole 612 and the second positioning hole 631 to rigidly connect the main tank 4 and the auxiliary tank 5. An oil inlet 41 is located on one side of the main tank 4, at about half its height. An oil replenishment port 51 is located on one side of the auxiliary tank 5, at about one-eighth of its height. The two ends of the oil pipe 2 are connected to the oil inlet 41 and the oil replenishment port 51, respectively. A main-auxiliary tank 5 connecting valve 21 is installed on the oil pipe 2. A first gas source inlet 42 is located on the other side of the main tank 4. The first gas inlet 42 is located at one-eighth of the height of the main tank 4. A second gas inlet 52 is located on the other side of the auxiliary tank 5. The gas supply pipe 3 is a three-way pipe, with its three ends being an inlet 31, a first outlet 32, and a second outlet 33. The first outlet 32 ​​is fixedly connected to the first gas inlet 42, and the second outlet 33 is fixedly connected to the second gas inlet 52. A gas supply device 1 is fixedly connected to the inlet 31. A first gas source equalization valve 34 is installed on the gas source pipeline 3 at the first gas outlet 32, and a second gas source equalization valve 35 is installed on the gas source pipeline 3 near the second gas outlet 33. The first gas source equalization valve 34 and the second gas source equalization valve 35 are opened simultaneously to adjust the gas pressure between the main tank 4 and the auxiliary tank 5, so that the gas pressure between the main tank 4 and the auxiliary tank 5 is kept consistent. The main and auxiliary tank 5 connecting valve 21 is opened, and the oil flows from the oil replenishment port 51 of the auxiliary tank 5 into the oil inlet 41 and reaches the main tank 4 by gravity.

[0034] An exhaust valve is installed on the top of the auxiliary tank 5, and the exhaust valve is fixedly connected to the auxiliary tank 5. An oil filling port 55 is installed in the center of the top of the auxiliary tank 5, and an oil filling plug 56 or a cleaning plug 57 is installed on the oil filling port 55. A viewing window interface 53 is installed on one side of the auxiliary tank 5, located at the lower third of the height of the auxiliary tank 5. An oil level viewing window 531 for observing the oil level inside the auxiliary tank 5 is installed at the viewing window interface 53, and the oil level viewing window 531 is fixedly connected to the viewing window interface 53. When all the oil in the auxiliary tank 5 flows into the main tank 4, the first air source equalization valve 34 and the main-auxiliary tank 5 connecting valve 21 are closed to make the auxiliary tank 5 independent. The pressure relief valve 54 on the top of the auxiliary tank 5 is opened to restore the pressure inside the auxiliary tank 5 to normal. At this time, the main tank 4 works normally. The auxiliary tank 5 can be filled with oil by opening the filling plug 56. The main tank 4 is equipped with a level gauge 44 for detecting the oil level inside the main tank 4. The level gauge 44 is detachably connected to the main tank 4. If the level gauge 44 detects that the oil level in the main tank 4 is too low, it will open the first air source equalization valve 34 and the main-auxiliary tank 5 connecting valve 21 to fill the oil in the auxiliary tank 5 into the main tank 4. The lower part of the main tank 4 is equipped with multiple sets of outlets 43. Multiple sets of injection valves 431 and multiple sets of exhaust valves 432 are installed on the outlets 43. The injection valves 431 are fixedly connected to one end of the outlets 43. The exhaust valves 432 are installed at the outlets 43. If there is too much air in the main tank 4 and the auxiliary pipe, the exhaust valves 432 will be operated to discharge the air through the injection valves 431.

[0035] Reference Figure 3 and Figure 4The top filler port 55 of the auxiliary tank 5 can be replaced with a cleaning plug 57. The cleaning plug 57 includes a housing 571, a bearing assembly 572, a first gear 573, a second gear 574, an electric motor 575, an inlet pipe 411, a guide pipe 577, and a high-pressure nozzle 578. The housing 571 is installed on the filler port 55 and is detachably connected to the filler port 55. One end of the inlet pipe 411 is fixedly connected to the housing 571, and the other end of the inlet pipe 411 is installed at the inlet of the guide pipe 577. The guide pipe 577 is rotatably connected to the inlet pipe 411. The inner ring of the bearing assembly 572 is mounted on the guide pipe 577, and the outer ring of the bearing assembly 572 is mounted on the housing 571. A first gear 573 is mounted on the guide pipe 577 on one side of the bearing assembly 572. The base of the electric motor 575 is mounted on the housing 571 on one side of the first gear 573. A second gear 574 is mounted on the working end of the electric motor 575. The first gear 573 and the second gear 574 mesh and drive the rotation through the auxiliary guide pipe 577 of the bearing assembly 572. The electric motor 575 provides rotation to the guide pipe 577. The power source is a guide pipe 577, and a high-pressure nozzle 578 is installed at the other end of the guide pipe 577. The guide pipe 577 is a curved pipe, and the high-pressure nozzle 578 is placed on the inner wall of the auxiliary tank 5. The guide pipe 577 rotates to flush the inner wall of the auxiliary tank 5. The oil inlet 41 of the main tank 4 is provided with an inlet pipe 411. The inlet pipe 411 is fixedly connected to the oil inlet 41. The inlet pipe 411 is a curved pipe, and the inlet pipe 411 is installed downward along the arc of the inner wall of the main tank 4 to guide the cleaning hydraulic oil to flow smoothly along the wall of the main tank 4 and spread downward to cover more areas.

[0036] The working principle of the non-stop oil replenishment system for the hydraulic oil tank of a compressor unit in this application is as follows: Before replenishing the auxiliary tank 5, ensure that the first gas source equalization valve 34 and the main-auxiliary tank 5 connecting valve 21 are in the closed state, disconnect the physical connection between the auxiliary tank 5 and the main tank 4 and the gas source device 1 to form an independent replenishment space, open the pressure relief valve 54 on the top of the auxiliary tank 5 to release the residual pressure in the tank to normal pressure, remove the oil filling plug 56, add hydraulic oil to the oil filling port 55 of the auxiliary tank 5, and use the liquid level in the sight glass as the observation basis to replenish the oil until the oil overflows from the sight glass, reinstall the plug and tighten it, close the pressure relief valve 54 to complete the pre-replenishment of the auxiliary tank 5, monitor the liquid level gauge 44 of the main tank 4, and when the oil level drops to three... When the volume is below one-third, initiate the replenishment process by opening the first gas source equalization valve 34 and the second gas source equalization valve 35 to balance the gas source pressure between the auxiliary tank 5 and the main tank 4. Simultaneously, open the main-auxiliary tank 5 connecting valve 21 to establish an oil replenishment channel. Oil flows from the auxiliary tank 5 to the main tank 4 by gravity through the main-auxiliary tank 5 connecting valve 21. Using the main tank 4 level gauge 44 as feedback, when the oil level rises to two-thirds of the volume, close the main-auxiliary tank 5 connecting valve 21 to cut off the replenishment path. The first gas source equalization valve 34 and the second gas source equalization valve 35 remain open to maintain consistent pressure between the main and auxiliary tanks 5, preventing pressure differences from disrupting system stability. After starting the unit, monitoring is required. Measure the ignition status of each cylinder. If an ignition abnormality occurs, it indicates that air has entered the pipeline due to fuel injection, causing air resistance. The exhaust valve 432 needs to be operated one by one to release the air through the injection valve 431 until each cylinder returns to normal ignition logic, ensuring stable operation of the unit's power unit. During cleaning of the main tank 4 and auxiliary tank 5, the fuel filler plug 56 is replaced with a cleaning plug 57. After the electric motor 575 in the cleaning plug 57 starts, the working end of the electric motor 575 drives the second gear 574 to rotate. The first gear 573 meshes with the second gear 574. The first gear 573 is fixed on the guide pipe 577, and the rotation of the second gear 574 drives the first gear 574 to rotate. A gear 573 and a guide pipe 577 rotate synchronously. The outer ring of the bearing device 572 is fixed on the outer shell 571, and the inner ring of the bearing device 572 rotates with the guide pipe 577 to ensure the stable rotation of the guide pipe 577. The guide pipe 577 is curved to accurately deliver the high-pressure nozzle 578 to the inner wall of the auxiliary tank 5. As the guide pipe 577 rotates, the high-pressure nozzle 578 will make a circular motion around the inner wall of the auxiliary tank 5, while spraying high-pressure cleaning hydraulic oil into the inner wall. When the cleaning fluid enters the main tank 4, the inlet pipe 411 will guide the cleaning fluid to flow smoothly along the wall of the main tank 4, so that the cleaning fluid can spread downward and cover more of the inner wall area of ​​the main tank 4.

[0037] The above are all preferred embodiments 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.
