羅茨水環(huán)真空機(jī)組的前級(jí)泵的工作液多采用水,也可采用有機(jī)溶劑(可用甲醇、乙醇、二甲苯、丙酮等有機(jī)溶劑)或其它液體,將前級(jí)泵作為閉路循環(huán)系統(tǒng)使用,大大減小了對(duì)環(huán)境的污染,同時(shí)大大提高了對(duì)有機(jī)溶劑的回收,其極限真空度由工作液的飽和蒸汽壓決定。
羅茨水環(huán)真空機(jī)組的選擇:
J代表機(jī)組的*個(gè)字母
ZJ代表主泵為ZJ系列羅茨真空泵
2B代表前級(jí)泵為2BV/2BE系列水(液)環(huán)真空泵
?。?S代表前級(jí)泵為2SK系列水(液)環(huán)真空泵)
300為主泵(羅茨泵)抽速 L/s
2.1為抽速配比代號(hào)
(即主泵與二級(jí)泵抽速比為2,二級(jí)泵與前級(jí)泵抽速比為1)
