该机组是以罗茨真空泵为主泵,旋片(或滑阀)真空泵为前级泵并配有电磁阀,管路等组成的成套真空获得设备。 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. 该设备具有结构紧凑、操作方便、抽气能力大、抽气时间短等特点。 This equipment has the features such as compact structure, easy to operate, good capacity of extracting and short time extracting. 广泛应用于真空冶金、真空脱气、真空镀膜以及空间模拟、低密度风洞等装置中,以抽除非腐蚀性气体,还可 用于医药、食品、电子、化工等工业的蒸馏、蒸发、干燥等生产过程。 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. 对于某些会有较多水分、粉尘的工艺必须配备过滤装置或冷凝器等,另外还可增加一台双级水环泵作粗抽, 使大量水分、粉尘由水环泵抽除,这样就可延长机组的正常使用寿命。 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. 主要技术性能指标:
