Abstract
Clean version of the Abstract A pneumatic type water-free starting self-priming device includes a driving device, and a gas-liquid separation chamber and an expandable gas-liquid separation chamber respectively arranged on two sides of the driving device. The driving device uses high-speed gas to drive a drive disk to rotate and drive a drive shaft to rotate. The gas-liquid separation chamber uses a telescopic piston shaft rod to generate a pressure difference between the gas-liquid separation chamber and outside to suck in water, so as to realize water suction, gas-liquid separation and water drainage. The expandable gas-liquid separation chamber uses shrinkage or expansion of volumes of inner and outer chambers to generate a pressure difference to suck in water, so as to realize water suction, gas-liquid separation and water drainage. Also, the high-speed gas from the driving device flows through the two chambers, so that air can be discharged quickly.
