氣體增壓幫浦系統的原理。
principle of gas booster pump system
氣體增壓幫浦是利用活塞兩端的面積差來獲得高壓氣體（液體）輸出，活塞的驅動氣體端是低壓的，活塞的另一端是小面積的高壓，增壓幫浦兩端的活塞桿容積不同， 驅動氣體進入與大活塞連線的腔體，通過氣動換向閥，大活塞可以往復，小活塞也往復。在活塞運動過程中，根據帕斯卡原理，在小活塞端產生高壓氣體（液體），幫浦往復運動，當輸出壓力接近設定壓力值時，幫浦往復運動減慢，直至停止，此時氣壓和液壓平衡，活塞基本保持靜止， 此時能耗最低，流體溫度不公升高，相反，當壓力降低時，幫浦開始工作。
a gas booster pump utilizes the area difference between the two ends of the piston to obtain high-pressure gas (liquid) output. the driving gas end of the piston is low-pressure, and the other end of the piston is high-pressure with a small area. the volume of the piston rod at both ends of the booster pump is different, and the driving gas is passed into the chamber connected to the large piston. through the pneumatic directional valve, the large piston can move back and forth, and the small piston can also move back and forth. in the process of piston movement, according to the pascal principle, high-pressure gas (liquid) is generated at the small piston end, and the pump operates back and forth. as the output pressure approaches the set pressure value, the pump's reciprocating operation slows down until it stops. at this time, the air pressure and liquid pressure are balanced, and the piston basically remains stationary. at this time, energy consumption is the lowest, and the fluid temperature no longer increases. conversely, when the pressure decreases, the pump starts to work.
