The working principle of the emulsion pump, from the concept of the tall, is Boyle's Law: the gas in the sealed container is inversely proportional to the pressure and volume of the gas at constant temperature. The formula is: p1V1 = P2V2. The popular understanding is: in the sealed container, the increase of volume leads to the decrease of pressure (suction / suction process), and the decrease of volume leads to the increase of pressure (discharge process).
