一、进口气体增压泵概述

威盾VTON的VDBA 系列气体增压泵，Gas booster pump，利用大面积活塞端的低压气体驱动而产生小面积活塞端的高压流体。可用于压缩空气及其它气体，输出气压可通过驱动气压无级调节。采用单气控非平衡气体分配阀来实现泵的往复运动，全部采用铝合金及不锈钢制造且密封件均为进口产品，主要应用于在输出气压高但流量要求不太高的应用场合。 泵型均可定制，参数定制，材质定制。

VDBA series gas booster pump from Weidun VTON, Gas booster pump， Using low-pressure gas from the large-area piston end to drive and generate high-pressure fluid from the large-area piston end. It can be used to compress air and other gases, and the output pressure can be infinitely adjusted by driving the pressure. Adopting a single gas controlled non-equilibrium gas distribution valve to achieve reciprocating motion of the pump, all made of aluminum alloy and stainless steel with imported seals, mainly used in applications with high output pressure but low flow requirements. Pump types can be customized, parameters can be customized, and materials can be customized.
