Embodiment Construction
[0039] specific implementation plan
[0040] The power supply of the equipment is DC low-voltage power supply, such as 24V DC power supply. The VLK series speed-adjustable vacuum pump can meet the working requirements of the device. It adopts brushless motor technology inside, which will not interfere with the control circuit. PWM speed regulation can be controlled by "duty cycle". To adjust the motor speed and change the output flow of the pump, there is no valve adjustment, the air system is simple, and multi-mode control such as constant flow and constant pressure can be realized. Built-in overheat protection and overload protection, allowing the medium to be rich in water vapor, it can run continuously for a long time around the clock, with low noise, and the volume is 87mm×40mm×75mm; the suction end can carry a large load and run in a locked rotor.
[0041] The control circuit adopts Z80processor as the control core, and connects it with the hardware control circuit board...
