我厂小方坯连铸机循环水系统配有一座150m~3的倒锥式水塔,用于意外停泵时,为连铸机供水。连铸机原供水系统工作原理如图1所示。工作前将水塔灌满水:关闭Z_2,开启Z_1,起动水泵,水沿α向进入水塔。水满后即停泵,关闭Z_1,打开Z_2。 正常生产时,起动水泵,开启Z_1。由于水塔内浮球阀F的作用,水泵输出的水仅能沿b向供往连铸机。当 Our company’s billet caster circulating water system is equipped with a 150m~3 inverted cone water tower, which is used to supply water for the continuous caster when the pump is stopped accidentally. The working principle of the continuous casting machine’s original water supply system is shown in Figure 1. Fill the water tower with water before work: turn off Z_2, turn on Z_1, and start the water pump. The water enters the water tower along the α direction. When the water is full, stop the pump, turn off Z_1, and turn on Z_2. In normal production, start the pump and turn on Z_1. Due to the action of the float valve F in the water tower, the water output from the water pump can only be supplied to the caster along b direction. when
