一、深井倾斜状况我厂1~#深井于69年12月底建成,井深84.6米,井管为铸铁管缠丝,接口采用六块钢拉板焊接。初测静水位-12.05米,装14JD370×3型深井泵。投产后水位不断下降。为改变这一状况,曾改装12J160×3小型深井泵,但改型后效果不明显,发现泵扬水管与井壁相碰,不能正常运行。1976年采 First, the situation of deep well tilting Our plant 1~# deep wells were completed at the end of December of 69, and the well depth was 84.6 meters. The well pipe was wrapped with cast iron pipe and the interface was welded with six steel pull plates. Initially measured static water level -12.05 meters, installed 14JD370 × 3 deep well pump. After the production, the water level keeps falling. In order to change this situation, the 12J160×3 small deep well pump was modified, but the effect was not obvious after the modification. It was found that the pump lift pipe collided with the well wall and could not operate normally. In 1976
