详细说明

  JZJ2B系列罗茨水环真空机组是由ZJ型罗茨泵作为主抽泵,2BV系列水环泵或罗茨--水环机组作为前级泵组成的抽气机组。它除了可以用来抽除一般气体外,还可以抽吸含有水分、有机溶剂或少量灰尘的气体。与一般机械真空泵相比,不怕油污染,不怕水气及微尘,而与一般的水环式真空泵相比,具有真空度高以及在高真空度工况下抽速大的特点。
     罗茨泵-水环泵真空机组广泛地用于化工、电子、机械、制药、食品升华干燥、高空模拟试验等的抽真空系统中。
     由于采用了高效节能的2BV系列水环泵用为前级泵,所以JZJ2B系列真空机组比JZJ2S系列具有效率高、结构紧凑、无泄漏(2BV泵为机械密封设计,不同于2SK系列的盘根密封)、耐腐蚀(2BV采用铝青铜叶轮)、防护等级高等优点。
     将前级泵中的工作液改为油时,可以有效地提高罗茨真空机组的极限真空度(见参数表),罗茨油环机组为闭路循环系统,可减少污染,节约水源。罗茨油环真空机组广泛应用于真空浸渍、真空干燥、真空除气等工艺中。
     前级泵的工作液也可采用有机溶剂(可用甲醇、乙醇、二甲苯、苯胺、丙酮等粘度较低的有机溶剂)或其它液体,将前级泵作为闭路循环系统使用,大大减小了对环境的污染,同时大大提高了对有机溶剂的回收。其极限真空度由工作液的饱和蒸汽压决定。                 

            
            
                

                    罗茨水环真空机组大致有如下几种类型:                 

                
                        
  •                         罗茨泵+水环泵:机组中水环泵的作用是造成罗茨泵所需的预备真空。                     
  •                     
  •                         罗茨泵+罗茨泵+水环泵:一台罗茨泵的极限真空度是较低的,特别是当它与水环泵组合运行时,使用范围受到限制,整个机组的极限真空度可能更低,但若用两台罗茨泵串联再与水环泵组合,就能大大提高机组的极限真空度。                     
  •                     
  •                         罗茨泵+罗茨泵+罗茨泵+水环泵:如两台罗茨泵+水环泵的方式还不能满足真空度要求时,可再加一级罗茨泵,此类罗茨水环真空机组在真空冷冻干燥等高真空工艺中得到了广泛地应用。                     
  •                 
                

                    型号表示方法                    

                

                          如:J Z J 2 B 1 5 0 - 2 . 1
           J代表机组的第一个字母
           ZJ代表主泵为ZJ系列罗茨真空泵
           2B代表前级泵为2BV/2BE系列水(液)环真空泵
             (2S代表前级泵为2SK系列水(液)环真空泵)
           150为主泵(罗茨泵)抽速 L/s
           2.1为抽速配比代号
           (即主泵与二级泵抽速比为2,二级泵与前级泵抽速比为1)

说明:1、以上表格仅为推荐标准系列,因在实际生产应用中工作条件的不同,吸入气体及压力会发生很多变化,所以在选型时应根据实际抽气过程、气体释放过程、可凝性气体冷凝情况、吸入压力的时间变化等等进行校核计算或根据现有设备使用情况选型。罗茨真空泵及水环真空泵也可根据实际情况另行配置。
       2、单泵的技术指标详见各泵技术参数
       3、如真空泵电机、电接点真空表、电控柜等需防爆,请在订货时注明,上表中的2BV5系列相应改为2BV6系列。
       4、最高吸入压力是指主泵能够启动的最高压力,如在高于该压力下启动主泵,可能会造成主泵过载。
