根据国家有关规定,企业高温产品、设备必须用工业循环水冷却,在这其中涉及循环水泵组、管网、换热装置、制冷设备、冷却塔等全流程,其主要依靠水泵来推动循环水流动。据不同国家工业统计,水泵的耗电量约占全国发电量的21%。当前,我国循环水用量已经占到工业用水总量的70%,工业循环水系统用泵能耗占到70%以上,运行能耗巨大。 According to the relevant regulations of the state, high-temperature products and equipment of enterprises must be cooled by industrial circulating water, which involves the whole process of circulating water pump set, pipe network, heat exchanger, refrigeration equipment and cooling tower, and mainly relies on water pump to promote circulating water flow . According to industrial statistics of different countries, the pump’s electricity consumption accounts for about 21% of the national electricity generation. At present, the amount of circulating water in our country accounts for 70% of the total industrial water consumption, and the energy consumption of industrial circulating water system pumps accounts for more than 70%, resulting in huge energy consumption in operation.
