目前在生活小区普遍采用水池或水箱断流的衔接方式,这样十几米水柱浪费的电量,远比使用调速泵二次加压所节省的电量高。不使这部份能量浪费一是尽量减少二次加压泵站,二是二次加压泵站应取消水池(水箱),使调速泵直接与城市管网相接,其前提得使市政管网满足最大时用水量,需水厂的二级泵站能供给最大时用水量。这一要求对新建或改建后的城市供水系统是不难作到的。这样从水厂的二级泵站到小区的二次加压泵站形成调速泵的串联供水,即可作到城市供水的最大节能。由于市政管网要求保证10m以上的消防水压,所以这种水泵连接方式至少可以节省10m以上的扬程。这
At present, in the living quarters, the connection mode of water or water tank disconnection is generally adopted, so that the power consumption of ten meters of water column is far higher than the power saved by the use of the secondary pressure of the speed control pump. Do not make this part of the energy wasted. Firstly, reduce the secondary pressurization pump station as much as possible. Second, the secondary pressurization pump station should cancel the pool (water tank) so that the speed control pump can be directly connected to the urban pipe network. When the pipe network meets the maximum water consumption, the secondary pump station of the water demand plant can supply the maximum water consumption. This requirement is not difficult to achieve for the newly built or converted urban water supply system. In this way, from the secondary pump station of the water plant to the secondary pressure pump station of the community, the series water supply of the speed control pump can be formed, and the maximum energy saving of the urban water supply can be achieved. Because the municipal pipe network requires a fire pressure of more than 10m, this type of pump connection can save at least 10m of lift. This
