概述：
Overview:
2BW5系列电力成套装置是为配套国家火电事业的发展，在原西门子水环真空泵的的基础上，经过多年与厂校科研院所联合攻关及实践经验的探索，形成一套完全适应国内火力发电行业6MW、12MW、15MW、25MW、50MW、135MW、200MW、300MW、600MW、1000MW发电机组水环式机械真空泵成套装置。全系列共七个规格多种配套形式。
2BW5 series complete set of power equipment is to support the development of national thermal power industry, based on the original Siemens water ring vacuum pump, after years of joint research and practical experience exploration with factories, schools and research institutes. Made a complete set of water ring type mechanical vacuum pump for 6 MW, 12 MW, 15 MW, 25 MW, 50 MW, 135 MW, 200 MW, 300 MW, 600 MW and 1000 MW generators, which are fully adapted to the domestic thermal power industry. The whole series of seven models of a variety of supporting forms.
