It is ideal corollary equipment for vacuum application equipment.But this unit is not suitable for the gases which exclude corrosion towards metals and chemical reaction towards pump oil.Now it is widely applied by solar product enterprises.</p><img src='http:///pic/125176/2/20160405145320_6083_zs_sy.jpg' /><img src='http:///pic/125176/1/20160307133712_5089_zs_sy.jpg' /><br /><p><br /></p>根据被抽真空系统的大小及气体状态，真空机组各泵之间的名义抽速之比一般在4∶1至10∶1之间，前者适用于较大真空系统及长时间在较低入口压力或极限真空情况下工作。本系列罗茨真空机组为了防止前级旋片真空泵停机返油，在前级管道上装有电磁放气阀，其动作与前级旋片真空泵的电机联动。<img src='http:///pic/125176/2/20160405144613_2517_zs_sy.jpg' /><br />
