补充资料:2BV系列水环式真空泵及压缩机
概述
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)。当用变压器油作为工作液时(称为油环真空泵),吸气压力可达到6.7mbar绝压(99.3%真空度),可以完全取代往复式真空泵。当真空泵在吸气压力接近极限真空下长期工作时,应联接气蚀保护管,以对泵进行保护。作为压缩机用时,其压力最大至0.26MPa(绝压)。2BV系列水环真空泵作为新一代节能型产品,其以出色的性能及众多优点将全面取代同性能的SK、2SK、W、WY、WL系列水环真空泵、往复真空泵。
相对于国内同类型SK、2SK、SZ等水环式真空泵,其有以下特点:
机泵同轴式直联设计,节省空间,易于安装。
全部采用国外进口机械密封作为标准配置。
运行平稳,噪音可低至62分贝。
铝青铜叶轮强度高,经久耐用,并提高了泵的耐腐蚀性。
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最佳。
全部采用Y2系列电机,防护等级IP54(普通为IP44)
