水轮发电机组恒定流量循环冷却技术供水系统

Constant Flow Circulating Cooling Water Supply System for Hydro-generator Set

水轮发电机组常规的冷却用水是从上游水库取水,经热交换后,排至下游水库。而这样从水库直接取水,即便经过多层过滤等,仍旧会产生泥沙、水生物、垃圾等,进而影响了机组的供水系统。而恒定流量循环冷却水供水系统大大减少了上述的干扰因素,也大大提高了冷却水的功效。

Generally, the cooling water for hydro-generator set is taken from the upstream reservoir and discharged to the downstream reservoir after heat exchanging, which inevitably brings sediment, aquatic life, garbage etc., into the cooling system even after multi-layer filtration, and directly influences the water supply system of the unit. However, the constant flow circulating cooling water supply system not only greatly reduces the above interference factors, lint also greatly improves the efficiency of cooling water.
