At present, most users install each component separately in the pipeline, and each component is dispersed in each area of the whole pipeline equipment, and then each component is connected by an oil pipe and electrically connected until the lubrication point of the equipment friction pair. Therefore, the following disadvantages exist in use: First, the connection of multiple pipelines between each component increases the risk of oil leakage; second, the installation of each component on the equipment is relatively chaotic and not convenient for maintenance; third, the wiring of each electrical component is not centralized and relatively chaotic.

Detailed Embodiments
[0015] The following further describes the present application in conjunction with the attached Figures 1 - 3 drawings for a more detailed description.
[0016] As Figure 1 and Figure 3 shown, an embodiment of the present application discloses an oil pump lubrication device, including a mounting plate 1, a lubricating oil pump, a filtering component, a pressure component, and a control component. The lubricating oil pump, the filter component, the pressure component, and the control component are integrally mounted on the mounting plate 1;
[0017] The lubricating oil pump includes a motor 10, a pump base 9, an oil storage cylinder 11, a pressure regulating valve 5, a bleed valve 6, a solenoid valve 7 and an exhaust valve 12. The exhaust valve 12 is installed on the side wall of the oil storage cylinder 11. The oil storage cylinder 11 is installed upside down, with the inlet and outlet openings facing downwards. There is an installation platform 18 integrally formed with the barrel body below the oil storage cylinder 11. The pump base 9 is provided below the installation platform 18 and is fixedly installed on the installation plate 1 by bolts; the pump base 9 is a multi-channel integrally formed structure, and the pump base 9 is fixedly connected to the installation platform 18 by bolts and is sealed by seals such as sealing rings; there is an oil passage inside the pump base 9 that communicates with the oil storage cylinder 11; the filtering component includes a filling port 2 and a filter 3. The filling port 2 is arranged in front of the filter 3. An oil outlet pipe 4 is installed on the right side of the filter 3. The filter 3 is connected to the oil passage of the pump base 9 through the oil outlet pipe 4 and leads to the oil storage cylinder 11. Lubricating oil is filled at the filling port 2, the motor 10 is started, and the lubricating oil enters the oil storage cylinder 11 through the filter 3 and the oil outlet pipe 4 after being filtered; the drain pipe 15 is connected to the oil storage cylinder 11 through the internal oil passage of the pump base 9, and the lubricating oil in the oil storage cylinder 11 is discharged through the drain pipe 15; a pressure regulating valve 5 is arranged between the drain pipe 15 and the oil storage cylinder 11. The pressure regulating valve 5 presets the oil discharge pressure, and the lubricating oil is pushed by a plunger to open the oil discharge valve, and the lubricating oil is discharged from the oil storage cylinder 11 into the drain pipe 15; a bleed valve 6 is connected to the side wall of the oil passage between the pressure regulating valve 5 and the oil storage cylinder 11. A solenoid valve 7 is arranged on the right side of the bleed valve 6. The solenoid valve 7 is provided with a pressure passage and a pressure relief passage. When the solenoid valve 7 is powered on, the pressure passage and the pressure relief passage are cut off. The motor 10 works to supply pressurized lubricating oil. When the system pressure reaches the set pressure value, the motor 10 and the solenoid valve 7 are powered off, and the main pipeline is depressurized. At this time, the pressure passage and the pressure relief passage of the solenoid valve 7 are connected, and the lubricating oil enters the pressure relief passage from the pressure passage and flows back to the oil storage cylinder 11; the pressure component includes a pressure gauge 8 and a pressure switch 19. The pressure gauge 8 is arranged on the drain pipe 15 near the oil discharge port 16. The pressure gauge 8 monitors the pressure state of the entire pipeline system in real time. When the pressure of the lubricating oil pump rises to the set threshold value, the contacts of the integrated pressure switch 19 will trigger actions such as closing or opening, and feedback the normal pressure signal to the control system; if the system pressure does not reach the expected value, such as insufficient pressure or abnormal decrease, the contacts of the pressure switch 19 will remain in the original state. At this time, the alarm mechanism is triggered through signal output to prompt the operator to check the pressure abnormality problem in time; an oil level transmitter 17 is arranged on the outer circumference of the installation platform 18 of the oil storage cylinder 11. The oil level transmitter 17 is used to monitor the lubricating oil inventory in the oil storage cylinder 11 in real time. When the oil level drops to the preset threshold value, its contacts trigger an action and send an alarm signal to the control system, timely prompting to replenish the lubricating oil to avoid lubrication interruption or equipment failure caused by insufficient oil volume, thereby ensuring the continuity and stability of the system operation. Each component forms a closed-loop system through the built-in channels and cooperation mechanism, reducing the leakage risk, simplifying the maintenance process, and ensuring that the lubrication process is efficient, controllable, stable and reliable.
[0018] AsFigure 1 As shown, the control component includes a terminal block 13 and a junction box 14. The junction box 14 is fixedly installed on the mounting plate 1 on the side of the oil storage barrel 11. The control wire harnesses of electrical components such as the motor 10, the solenoid valve 7, the oil level transmitter 17, and the pressure switch 19 are centrally introduced into the junction box 14 and connected to the terminal block 13. The terminal block 13 is simultaneously connected to an external PLC controller. Through the centralized management of electrical components and signal processing by the external PLC controller, the automation and intelligence of the lubrication process are realized; the centralized management of the control wire harness facilitates wiring and fault repair.
[0019] As Figure 2 shown, the control component includes a controller 20 and a controller housing 21. The controller housing 21 is fixedly installed on the mounting plate 1 on the side of the oil storage barrel 11. The control wire harnesses of electrical components such as the motor 10, the solenoid valve 7, the oil level transmitter 17, and the pressure switch 19 are centrally introduced into the controller housing 21 and connected to the controller 20. The operation cycle and status of the grease pump lubrication device can be directly monitored through the controller 20, and only the power supply needs to be connected externally, further improving the integration level of the grease pump lubrication device.
[0020] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
