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.
机泵同轴式直联设计,节省空间,易于安装。采用机械密封作为标准配置,xx了泄露,维护简便。运行平稳,噪音可低至62分贝。统一的耐腐蚀设计,青铜叶轮提高了泵的耐腐蚀性,如采用不锈钢材质更适用于更为苛刻的应用。独特的柔性排气口设计,不会产生过压缩,确保了2BV在其性能范围内效率
