This is a concept in the field of miniature vacuum pumps. Mainly refers to a miniature vacuum pump that can adjust the flow parameters of the air pump by electronic control. Its most notable feature is the use of diaphragms for variable speed operation and high-end full-function brushless motors. It can change the flow rate by adjusting the motor speed through the pulse width modulation (PWM) function of the electronic circuit. It is easier and more suitable for automatic control than installing a “flow control valve†solution in the pipeline. The "speed control vacuum pump" has high requirements for brushless motors, diaphragms and moving parts, and the manufacturing process is also very particular. The corresponding products are VML series, FML series, VLC series, VLK series, etc. The specific models are: VML801.5, FML100.8 and so on.
In addition to the above basic speed control functions, the brand manufacturers' products have many very good additional functions, such as: long life, low interference, feedback signals and so on.
