自来水厂平流式沉淀池的排泥,一般采用行车式吸泥机较多,常用的有泵吸式和虹吸式两种。我厂沉淀池是采用泵吸式吸泥机,其结构如图1(该机共有两台吸泥泵,每台泵有8个吸口)。 在使用过程中,发现该机由于流进沉淀池的原水杂物多,经常将吸口、吸管堵塞,使吸泥泵无法正常工作。如用工具疏通,只有将行车上下翻转方能进行,这样不但花费大、时间长,而 The sludge from the flat-flow sedimentation tank in the waterworks generally uses suction dredgers, which are commonly used as pump suction and siphon suction. The sedimentation tank of our factory is a pump suction suction machine. Its structure is shown in Figure 1. (The machine has two suction pumps, each pump has 8 suction ports). In the course of use, it was found that the machine has many impurities in the raw water flowing into the sedimentation tank, and often the suction port and the suction pipe are blocked, so that the suction pump cannot work normally. If you use tools to clear, you can only turn the car upside down. This will not only cost a lot but will take a long time.
