目前,国内玻璃钢冷却塔生产已初成系列,批量投产的按每小时冷却处理量有4、8、15、30、50、100、200、800、500吨型等多种规格产品,可供用户方便地选择。循环水泵(以下简称环水泵)由于玻璃钢冷却塔的使用场所,安装高度不同,必须正确选择。环水泵选择合理与否,不仅影响到冷却塔的使用效果,而且关系到能否节电。所 At present, the production of domestic FRP cooling towers has become a series of products. The mass production per hour for cooling and batch processing includes 4, 8, 15, 30, 50, 100, 200, 800, 500 tons and other specifications, which are available to users. Easy to choose. The circulation pump (hereinafter referred to as the ring pump) must be correctly selected because of the different installation heights of the glass fiber reinforced plastic cooling tower. Whether the ring pump is reasonable or not affects not only the use of the cooling tower, but also whether it can save electricity. By
