[0002] A vacuum pump is a device used to create a vacuum and is widely used in various industrial and research fields. It is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate the container to create a vacuum. Vacuum pumps can be divided into various types based on their operating principles, including dry screw vacuum pumps, oil-free reciprocating vacuum pumps, claw vacuum pumps, and oil-free scroll vacuum pumps.

[0003] To maintain the required vacuum level, a vacuum system controller is often required on the vacuum pump to precisely control its start and stop. This controller automatically turns the vacuum pump on and off based on actual demand, monitors pressure changes in the vacuum system, automatically adjusts the vacuum pump's operating status according to preset parameters, and optimizes the energy efficiency of the entire system. Modern vacuum system controllers are typically equipped with advanced PLCs and touchscreen interfaces, making operation simpler and more intuitive. These devices can monitor the vacuum level in real time and automatically adjust the vacuum pump's operation as needed.

[0004] The existing vacuum pump start-stop control system can automatically start and stop, but it needs to be equipped with an electrical box and configured with multiple electrical components with related functions, which takes up a large space. The general electrical components have high energy consumption. The system composed of general electrical components requires manual wiring, which is costly and time-consuming. In view of this, the present application proposes a vacuum system controller that controls the start and stop of the vacuum pump. Utility Model Content

[0022] Example 1: Please refer to Figures 1 to 4 A vacuum system controller for controlling the start and stop of a vacuum pump comprises a vacuum tank 1, a connecting tube 2 disposed at the top of which is a controller 3. Controller 3 utilizes a single-chip integrated circuit (IC) and integrates multiple functional modules, including a power transformer module, an overheat protection module, an air pressure detection module, and a relay output module, within a small enclosure. This enclosure integrates all modules, significantly reducing power consumption and requiring minimal installation space.

[0023] The top of the vacuum tank 1 is fixedly mounted with a detection mounting port 4, with a sensor body 5 passing through the top of the detection mounting port 4. A negative pressure detection head 6 is fixedly mounted on one end of the sensor body 5 located inside the vacuum tank 1. A connecting hard tube 2 is threadedly mounted on the top of the sensor body 5. A mounting base 7 is fixedly mounted on the bottom of the controller 3. A detection input terminal 8 is fixedly mounted on the bottom of the mounting base 7. The connecting hard tube 2 is threadedly connected to the detection input terminal 8. A transmission line 9 is fixedly mounted on the top of the sensor body 5. The controller 3 is mounted on the top of the vacuum tank 1 through the connecting hard tube 2, which facilitates installation.

[0024] Secondly, a connection end 91 is fixedly installed at one end of the transmission line 9 , and the connection end 91 passes through the connecting hard tube 2 and is inserted into the interior of the detection input end 8 .

[0025] At the same time, a display screen 10 is fixedly mounted on the top of the controller 3. Adjustment buttons 11 are fixedly mounted on the top of the controller 3 and on both sides of the display screen 10. The upper and lower limits of the vacuum pump are set by adjusting the buttons 11. When the negative pressure detection head 6 detects the negative pressure value in the vacuum tank 1, the controller 3 adjusts the start and stop of the vacuum pump according to the real-time situation.

[0026] Among them, a power supply terminal 12 is fixedly installed on the back of the controller 3, and a vacuum control terminal 13 is fixedly installed on the back of the controller 3. The power supply terminal 12 is connected to the power supply through a wire 14, and the vacuum control terminal 13 is connected to the vacuum pump through a wire 14.

[0027] Secondly, a fixing clamp 15 is installed on the back of the controller 3 through a fixing screw 16 , and the wire 14 is clamped on the back of the controller 3 by the fixing clamp 15 .

When the measured negative pressure value exceeds the set upper limit value, the vacuum pump is shut down. After the vacuum pump is shut down, the vacuum value in the vacuum tank 1 will continue to decrease when the equipment is used until it falls below the set lower limit value and the vacuum pump is turned on again.
