Abstract: The article points out the harm done to equipment and production owing to the motor-pump shafts running out of axial center, revealing that as the construction and inspecting criteria vary for installation of motors and pumps, the present pipeline .construction companies have to have some work redone wastefully.To meet "The State Standard"， a simple and practical method is particularly introduced to correct and adjust the motor-pumps hafts, which is proved 0K through data computation, It is suggeated to popularize it in order to highten the engineering installation quality.
