抽水站按其作用来分，有灌溉抽水站、排水抽水站、灌溉和排水结合的抽水站等，它们在农业生产中发挥着重要的作用。然而引渠淤积却常常是困扰许多抽水站的重大问题，易于淤积的部位往往集中在引渠的进口段。 为了免受泥沙淤积，不影响抽水站的正常运行，取水口应远离泥沙淤积区 Pumping stations according to their role points, there are irrigation pumping stations, drainage pumping stations, irrigation and drainage pumping stations, etc., which play an important role in agricultural production. However, deposition silos are often the major problems plaguing many pumping stations. The silt-prone parts tend to be concentrated in the import section of the canals.
