用途及使用范围:
2BV系列水环真空泵适用于抽除气体和水蒸气，吸气压力可以达到33mbar绝压(97%真空度)。当水环真空泵在吸气压力接近极限真空(工作液的饱和蒸汽压)下长期工作时，应联接汽蚀保护管，以对泵进行保护。作为压缩机用时，其压力最大至0.26MPa(绝压)。
该系列广泛适用于化工、医药、食品、钢铁等行业。
结构及特点：
a) 机泵同轴式直联设计，节省空间，易于安装;
b) 采用机械密封作为标准配置,消除了泄露,维护简便;
c) 运行平稳，噪音低。统一的耐腐蚀设计，青铜叶轮提高了泵的耐腐蚀性，不锈钢材质更适用于更为苛刻的应用;
d) 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较佳。
