該機組是以羅茨真空泵為主泵，旋片（或滑閥）真空泵為前級泵并配有電磁閥，管路等組成的成套真空獲得設備。
This unit is a complete set of vacuum equipment, which treates roots pump as the main

pump,  rotary-vane (or slide valve) vacuum pump as prepump equipped with solenoid valve and pipes.

    該設備具有結構緊湊、操作方便、抽氣能力大、抽氣時間短等特點。
This equipment has the features such as compact structure, easy to operate, good 

capacity of extracting and short time extracting.

    廣泛應用于真空冶金、真空脫氣、真空鍍膜以及空間模擬、低密度風洞等裝置中，以抽除非腐蝕性氣體，還可

用于醫藥、食品、電子、化工等工業的蒸餾、蒸發、干燥等生產過程。
It is widely used in the equipments such as vacuum metallurgy, vacuum degassing, vacuum 

coating, and space simulation, low-density wind tunnel to extract corrosive gas. It can 

also be used in the manufacturing process such as distillation, evaporation and drying

 in the industries such as medicine, food, electronics, chemicals. 

    對于某些會有較多水分、粉塵的工藝必須配備過濾裝置或冷凝器等，另外還可增加一臺雙級水環泵作粗抽，

使大量水分、粉塵由水環泵抽除，這樣就可延長機組的正常使用壽命。
Filter or condensers must be equipped for some processes with more water and dusts. 

In addition, two-stage water-ring pump can be use for rough pumping so a large quantity 

of water and dusts are extracted by water-ring pump. And then the normal life of the 

unit can be extended.
