7.5kw constant pressure variable frequency vacuum pump for cutting machine

7.5kw constant pressure variable frequency vacuum pump for cutting machineThe working principle mainly relies on frequency converters and pressure sensors to achieve precise control of the pump's operating speed and system pressure. The core of a constant voltage variable frequency vacuum pump lies in its variable frequency control system, which precisely controls the working state of the pump by adjusting the speed of the motor.

Working principle of constant pressure variable frequency vacuum pump

1. Variable frequency control: The frequency converter adjusts the motor speed by changing the power supply frequency, thereby controlling the pumping capacity of the pump. When the system pressure is lower than the set value, the frequency converter will increase the power supply frequency to accelerate the pump and improve the pumping speed; On the contrary, when the system pressure is higher than the set value, the frequency converter will reduce the power supply frequency to slow down the pump and reduce the pumping speed by 12.

2. Pressure feedback: The pressure sensor in the system monitors the system pressure in real time and feeds back the signal to the controller. The controller compares the feedback pressure signal with the set pressure value and adjusts the output frequency of the frequency converter to maintain stable system pressure.
