吉化铁东生活水厂高峰用水量和平时用水量变化甚大。目前用调节水泵出口阀门开启度的形式来控制出厂水的压力,造成大量的能量消耗在阀门上;后采用多台水泵并联调节运行,虽然做到供水与用水的基本吻合,但节电效果不甚理想,况且采用节流,不但降低水泵的运行效率,还因在节流过程中调节阀的阀板两侧压力差过大,极易造成阀门的严重损坏及增加振动和噪声。为
Jihua Iron and Steel East Water Works peak water consumption and peacetime water consumption varies greatly. At present, the outlet pressure of the outlet of the pump is adjusted to control the pressure of the factory water, resulting in a large amount of energy consumption on the valve. After multiple pumps are used to regulate the operation in parallel, although the water supply and the water are basically matched, the power saving effect is not In addition, the use of throttling not only reduces the operating efficiency of the pump, but also causes excessive pressure difference on both sides of the valve plate of the regulating valve in the throttling process, which can easily cause serious damage to the valve and increase vibration and noise. for
