[0005] Further, the controller is a PLC.

[0006] Further, the lubricating pump is one of a positive displacement pump, a vane pump, a vacuum pump, a jet pump and a water hammer pump.

[0007] Further, the lubricating pump is provided with a lubricating button, and the lubricating button is used for controlling the on-off of the second circuit.

[0008] Advantages: compared with the prior art, the utility model has the following advantages:

[0009] Through the combination of the key switch, the main clutch button and the controller, the automatic start of the lubricating system is realized. This design reduces the manual operation steps and improves the work efficiency.

[0010] The automatic stop program built in the controller can automatically stop the work of the lubricating pump after a predetermined time, avoids unnecessary energy waste and excessive lubrication, and is helpful to protect the equipment and prolong the service life.

[0011] The instrument is provided with an operation interface, allowing the user to set the predetermined time according to actual needs, increasing the flexibility and user-friendliness of the system.

[0012] The system supports multiple types of lubrication pumps, such as positive displacement pumps, vane pumps, etc., providing users with more options and allowing them to choose the most suitable lubrication pump type based on actual needs.

[0013] The system's safety is increased through the settings of the main clutch button and the lubrication button. Only when certain conditions are met (such as the key switch being on and the main clutch being pressed) will the system start or continue to work, which helps prevent accidents caused by misoperation.

[0014] The circuit and component design of the system are relatively simple and easy to maintain and troubleshoot, which reduces maintenance costs and ensures the continuous and stable operation of the system. BRIEF DESCRIPTION OF DRAWINGS
