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)。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系列水环真空泵及W、WY、WL系列往复真空泵。

　　2BV2-Ex、2BV6系列水环式真空泵/压缩机主要用于抽除爆炸性气体，及在各类易燃、易爆环境中工作，其性能参数与2BV2、2BV5系列相同。

　　2BV系列不锈钢真空泵可使用在各种耐腐蚀要求较高的场合及洁净度要求较高的场合。
　　根据工况2BV系列不锈钢真空泵的全部过流部件：叶轮、圆盘、泵盖、泵体材质可选用
　　SUS304（0Cr18Ni9)
　　SUS316（0Cr17Ni12Mo2）
　　SUS316L（00Cr17Ni14Mo2）
    等各类不锈钢材质，泵轴材质：2Cr13、SUS304或SUS316L
　　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

　　主要特点：

• .电机直联设计，节省空间，易于安装，维修方便。

• .全部采用国外进口机械密封作为标准配置。

• .全部设有汽蚀保护管接口，如在极限压力下工作，开启汽蚀保护管接口（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汽蚀声，并对泵进行保护。

• .2BV全系列标准配备不锈钢叶轮，2BV2系列全部配备不锈钢圆盘/叶轮。强度高，经久耐用，并提高了泵的耐腐蚀性。如过流部件全部采用不锈钢材质，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、IP55（普通为IP44），绝缘等级为F级绝缘（普通为B级绝缘）

• .全部采用NTN或NSK进口轴承

• .2BV系列水环式真空泵可实现柔性密封件全部为聚四氟乙烯，从而可大大延长真空泵在苛刻工况下的使用寿命。

　　Shandong Bozhong Vacuum Equipment Co., Ltd (former name Zibo Bozhong Vacuum Equipment Co., Ltd) is one of the most professional manufacturers in China, which produces the water ring vacuum pumps, the Roots pumps and vacuum package units and vacuum driers etc. It locates in the famous historical city of Qi&Lu dynasty-Zibo city. The company is next to the 205 national highway in the east and the expressway from Binzhou to Boshan in the west. It is next to the 309 national highway in the south and the railway from Qingdao to Jinan in the north. So the traffic is convenient and the information is transmitted rapidly.

　　In March, 2002, Shandong Bozhong Vacuum Equipment Co., Ltd. was founded. Accompanying with its growth, it has attracted more and more advanced techniques and persons of ability. The professional staff make the superexcellent products. The quality policy of Shandong Bozhong company is leaded by the science and technology, seeking for the perfect, putting the clients' satisfaction and the excellent quality of the product to the first, obeying the promise and guarantee and improving itself continually. In 2002, the company had initially passed the ISO9001:2000 QMS certificate. Furthermore, nine types of the water ring vacuum pumps had obtained the safety symbol certificate issued by the National Mine Products Safety Symbol Office. 2008, LG series screw vacuum pump won the national utility model patent. 2012, Bozhong was jointly identified as" High-tech Enterprises" by the Shandong provincial Science & Technology Department, Finance Department, State Taxation Bureau and local Taxation Bureau. On March 15th, 2014, the company declared “Zibo City Screw Vacuum Pump Engineering Technology Center", "Hefei University of Technology - Bozhong Vacuum Production & Study & Research Base" formally founded. At present, Bozhong won 16 national practical new patent certificates and 2 invention patent certificates including multistage Roots vacuum pump, MVR pump etc. In November 2015, Bozhong was awarded the honorable title of" Model Home of Workers" by all-China Federation of Trade Unions; in November 2015, Bozhong became a corporate member of China Vacuum Society. In January 2016, Bozhong is hired as vice chairman unit of the “Journal of Vacuum Science and Technology” Council.

　　After over ten years of development, Shandong Bozhong Vacuum Equipment Co., Ltd. has grown to be the domestic leading manufacturer specializing in the production of water ring vacuum pump, Roots water ring vacuum pump and package units.
