In the present paper, the grading rules, which is about the deep-well bush pump, of the current standard promulgated by the ministry of petroleum of our country are analyzed according to their clear - ance. The relationship between the no bush deep - well pump clearance, whose diameter is big, and operational performance, leakage, friction-al wear and manufacturing performance is studied. And the deep-well pump is suggested to be typical according to the principal of equal efficiency and equal fit and practicability prin-cipal of manufacturing engineering.
