水环真空泵 进口水环真空泵 德国进口水环真空泵Water ring vacuum pump
水环真空泵概述
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。当液环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，以对泵进行保护并消除气蚀声。作为压缩机使用时，其压力最大至0.26MPa(绝压)。作为压缩机使用时，随着排气压力的升高会造成2BV泵功率的加大，订货时应注明排气压力以选择适当的电机功率。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、水环真空泵。主要用于抽除爆炸性气体，及在各类易燃、易爆环境中工作，

等各类不锈钢材质，泵轴材质：2Cr13或0Cr18Ni12Mo2Ti
机械密封采用进口产品，密封件可采用氟橡胶或聚四氟乙烯
水环式真空泵特点：
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。
2BV系列全部设有气蚀保护管接口，如在极限压力下工作，开启气蚀保护管接口（或与分离器连接）可在最大限度保证吸气效果的情况下消除气蚀声，并对泵进行保护。
铝青铜叶轮强度高，经久耐用，并提高了泵的耐腐蚀性。如过流部件采用不锈钢材质，可工作在更为苛刻的环境中。
独特的柔性排气口设计，不会产生过压缩，确保了真空泵在其性能范围内效率。
全部采用Y2系列电机，防护等级IP54、IP55（普通为IP44）
全部采用NTN或NSK进口轴承
The water ring vacuum pump is suitable for pumping the gas and water vapor, and the suction pressure can reach 33mbar absolute pressure (97% vacuum degree). When the transformer oil is used as the working fluid (called the oil ring vacuum pump), the suction pressure can reach 6.7mbar absolute pressure (99.3% vacuum), which can completely replace the reciprocating vacuum pump. When the liquid ring vacuum pump in the suction pressure near the limit vacuum work for a long time, should be connected to the cavitation protection tube, to protect the pump and eliminate cavitation. As the compressor is used, the pressure is up to 0.26MPa (absolute pressure). As the compressor is used, the 2BV pump power will be increased with the increase of exhaust pressure, and the exhaust pressure should be indicated in order to select the proper motor power. Water ring vacuum pump as a new generation of energy-saving products, with its excellent performance and many advantages, will be able to fully replace the same nature of SK, water ring vacuum pump. Mainly used to remove explosive gases, and in all kinds of flammable and explosive environment work,
Parameters of water ring vacuum pump
Stainless steel vacuum pump can be used in a variety of occasions requiring high corrosion resistance and cleanliness requirements of higher occasions. According to the working conditions, 2BV series stainless steel vacuum pump all over flow parts: pump body, pump cover, disc, impeller, material can be selected
SUS304 (0Cr18Ni9)
SUS316 (0Cr17Ni12Mo2)
SUS316L (00Cr17Ni14Mo2)
Other stainless steel material, pump shaft material: 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seal adopts imported products, and the seals can be made of fluorine rubber or Teflon
Characteristics of water ring vacuum pump:
The coaxial connection of pump and pump saves space and is easy to install.
All imported mechanical seals are used as standard.
2BV series of cavitation protection tube is provided with an interface, such as working in extreme pressure, open the cavitation protection tube interface (or separator connection) can ensure maximum suction effect under the condition of eliminating the cavitation noise, and the protection of the pump.
The aluminum bronze impeller is of high strength and durability, and improves the corrosion resistance of the pump. If the flow parts are made of stainless steel, they can work in more demanding environment.
The unique flexible exhaust port design eliminates excessive compression and ensures the efficiency of the vacuum pump in its performance range.
All use Y2 series motors, protection level IP54 and IP55 (usually IP44)
All adopt NTN or NSK imported bearings
