本系列驱动活塞直径为160mm。最大驱动气压为10bar，为了保证泵的寿命，建议使用气压<8bar。

Weidun VTON Butane booster pump， The pump adopts a single gas controlled non-equilibrium gas distribution valve to achieve automatic reciprocating motion, and the gas driven part of the pump body is made of aluminum alloy. The liquid receiving part is made of carbon steel or stainless steel according to different media, and the complete set of seals for the pump are imported high-quality products, ensuring the performance of the pump.

The diameter of the drive piston in this series is 160mm. The maximum driving air pressure is 10 bar. To ensure the lifespan of the pump, it is recommended to use an air pressure of less than 8 bar.

二、进口丁烷增压泵系统原理

丁烷增压泵是利用活塞两端的面积差而获得高压气体（液体）输出，活塞的驱动气体端是低压，另一端活塞是高压小面积，增压泵活塞杆两端体积不同，将驱动气体通入与大活塞相连的腔，通过气控换向阀，大活塞可以往复运动，小活塞也往复运动。在活塞运动过程中，根据帕斯卡原理，在小活塞端产生高压气体(液体），泵往复工作，随着输出压力接近设定压力值时，泵往复工作减慢直至停止，此时气压力和液压力平衡，活塞基本保持静止，此时能量消耗最低，流体温度不再增加，反之当压力降低时泵开始工作。

The butane booster pump uses 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 two ends of the booster pump piston rod have different volumes, and the driving gas is introduced 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. During the movement of the piston, according to Pascal's principle, high-pressure gas (liquid) is generated at the small piston end, and the pump works back and forth. As the output pressure approaches the set pressure value, the reciprocating work of the pump slows down until it stops. At this time, the air pressure and hydraulic pressure are balanced, and the piston basically remains stationary. At this time, the energy consumption is the lowest, and the fluid temperature no longer increases. Conversely, when the pressure decreases, the pump starts to work.
