该机组是以普通罗茨真空泵为主泵,以双级水环式真空泵为前级泵的自动启闭,自动过载保护的成套真空获得设备。 This unit is complete vacuum equipment which treats general Roots vacuum pump as the main pump, two-stage water-ring vacuum pump as prepump to achieve automatic open, close and overload protection. 它除了具有一般罗茨真空泵机组的一些特点外,由于采用水环式真空泵作前级泵,因此,它特别适用于抽除含较多蒸气 及有一定腐蚀性气体的工业流程中。例如:制药业的真空蒸馏、真空蒸发、脱水结晶;轻纺工业的涤纶切片干燥;食品工业 的冷冻、干燥等工艺均可采用。
Besides having some features of general Roots vacuum pump, this unit treats two-satege water-ring vacuum pump as prepump, so it is specially suitable for industrial-process with a large quantity of vapor and some corrosive gases.For example:The process such as vacuum distillization, vacuum evaporation, dehydration and crystallization in pharmacy, polyester chips drying in textile industry, freezing and drying in food industry could be adpoted. 主要性能指标:
