空分空压车间的冷却水改造北京东方化工厂空分空压车间是东方化工厂生产氧气、氮气、仪表用压缩空气和杂用空气的车间。由于生产规模不断扩大，用水量逐年增加，造成水压不足，严重影响生产。针对这个问题，他们将冷却水系统由有压回水改为无压回水，解决了仪表同空压机的... Air Separation Air Pressure Workshop Cooling Water Retrofit Beijing Oriental Chemical Plant Air Separation Air Compression Plant is a plant that produces oxygen, nitrogen, instrumentation compressed air and miscellaneous air at Oriental Chemical Plant. Due to the continuous expansion of production scale, water consumption increased year by year, resulting in insufficient water pressure, seriously affecting production. In response to this problem, they will change the cooling water system from pressurized water back to no pressure backwater, to solve the instrument with air compressor ...
