前言深井是化肥行业的重要设施之一。它的供水量直接影响着化肥生产。新凿深井一般存使用2～3年后,因井筒下部滤水网淤积阻塞而使出水量逐年下降,虽经空压机冲洗,可使出水量有所提高,但使用一段时间后仍重蹈覆辙;有时还因滤网局部腐蚀,在反复冲洗时,常造成网眼部分被破坏,造成 Introduction Sham Tseng is one of the important facilities in the fertilizer industry. Its water supply directly affects fertilizer production. Newly drilled deep wells are generally stored for 2 to 3 years, and the amount of water discharged from the bottom of the wellbore is blocked due to siltation. The flushing of air compressors can increase the amount of water produced, but it still repeats the mistakes after a period of time. Sometimes due to the local corrosion of the filter, when it is washed repeatedly, it often causes the mesh part to be destroyed, resulting in
