在城市排涝泵站中,对于河道水质不好,不能作为冷却水源,而与水泵配套的电机又必须使用水冷却时,通常只能选用冷却塔一种冷却方式。冷却塔通常体积比较庞大,运行噪音高,维护成本比较高,对周遍环境影响大,不十分适用在城市排涝泵站中。本文根据城市排涝泵站的运行特点,提出一种新的冷却方式,避免了冷却塔的上述缺点。 In urban drainage pump station, water quality is not good for the river, can not be used as a cooling water source, and with the pump supporting the motor and must use water cooling, cooling towers can usually only choose a cooling method. Cooling towers are usually relatively large size, high operating noise, high maintenance costs, environmental impact on the environment, not very suitable for urban drainage pump station. According to the operation characteristics of urban drainage pump station, a new cooling method is proposed to avoid the above disadvantages of cooling tower.
