白石水库混凝土拌和制冷水系统为预冷混凝土的辅助措施 ,是混凝土加冷水拌和系统 .该系统由冷水机组、循环水箱、水泵和拌和楼水箱组成 .由于在原制冷运行过程中制冷水温一直达不到设计要求的 4℃ ,制约了混凝土制冷效果 ,故进行了技术改造 .具体作法有 :改造制冷机组与水箱管路 ;改造不配套的原制冷水箱与水泵 .改造后运行达到预想效果 ,满足了拌和楼对冷水系统的要求 ,达到了混凝土冷水拌和的辅助作用
The concrete mixing chilled water system in Baishi Reservoir is an auxiliary measure for pre-chilled concrete, and is a concrete mixing chilled water mixing system, which is composed of a chiller, a circulating water tank, a water pump and a mixing tank. Because the cooling water temperature in the original cooling operation has not reached The design requirements of 4 ℃, restricting the effect of concrete cooling, so the technical transformation of the specific practices are: to transform the refrigeration unit and the water tank pipeline; transformation of the original does not complete the cooling water tank and pump operation after transformation to achieve the desired effect to meet the mixing House on the cold water system requirements, reached the auxiliary role of concrete cold water mixing
