所谓限流孔板,就是在钢板上钻上一个或多个孔的节流装置,它的应用范围很广。我厂使用的都是单孔限流孔板。 应用之一 污水处理车间用一只污水泵同时向两只相同的污水池输送污水,要求进入两只污水池的水量大体相等。原来的设计方案如图1(a)所示:用两只流量表监视水流量。使用限流孔板后的方案如图1(b)所示,这里减少一只流量计。两只限流孔板保证了 The so-called flow-limiting orifice, is one or more holes drilled in the steel plate throttling device, its wide range of applications. I plant are used single-orifice current limiting orifice. One of the applications A sewage treatment plant uses a single sewage pump to deliver sewage to two identical sewage reservoirs at the same time, requiring approximately equal amounts of water to enter the two sewage reservoirs. The original design is shown in Figure 1 (a): Use two flow meters to monitor water flow. The use of current limiting orifice after the program shown in Figure 1 (b) below, to reduce a flowmeter. Two current limiting orifice is guaranteed
