JZJLS型气体循环冷却罗茨泵+水环泵真空机组
Model JZJLS Roots Pump with Circulated Gas-cooling + Water-ring Vacuum Pump Unit  


该机组是以ZJL型气体循环冷却罗茨真空泵为主泵或中间泵,以2SK或2BEA型双级水环式真空泵为前级泵的真空获得设备。
This unit is a set of vacuum equipment, which treats Model ZJL Root pump with circulated gas-cooling as the main pump or middle pump and Model 2SK or 2BEA two-stage water-ring vacuum pump as prepump.


该机组除了具有一般罗茨真空水环泵机组的某些特点外,还能在高压缩比,高压差下正常工作,这样就大大缩短了对系统的预抽时间,获得较低的预抽压力。
Besides having some features of general Roots vacuum water-ring pump unit, this unit can work normally under high compression rate and high pressure differences. So the time of pre-extracting is greatly shortened with lower pre-extracting pressure.


本机组由于采用双级水环真空泵作为前级泵,因而本机组特别适用于抽除含有大量水蒸汽和带有一定腐蚀性及可凝性气体的工艺过程中,例如真空浸渍、真空干燥;化工产品的真空蒸馏、真空蒸发、脱水结晶;轻纺工业的涤纶切片干燥等。
This unit treats two-stage water-ring vacuum pump as prepump, so it is specially suitable for the process with a large quantity of vapor and some corrosive and condensable gases. For example, vacuum impregnation, vacuum drying, vacuum distillation, vacuum evaporation, dehydration and crystallization for chemical products and polyester chips drying in textile industry etc.
