QIDO pneumatic booster pumpThe core of pneumatic booster pump is the principle of pressure doubling: Intake stage: Compressed air enters the driving piston chamber, pushing the large area piston forward Compression stage: The large area piston drives the large area plunger to compress the pressurized medium Reversing stage: When the piston reaches the end of its stroke, the pneumatic distribution valve automatically changes direction, and the piston moves in the opposite
