1) Fix the outer foot on the side of the motor of the lifting accessories coupling, and move the inner foot until the eccentric line between the motor and the pump center is zero.To ensure that the motor does not move arbitrarily, after fixing the feet of one side of the motor, the other side should be supported by the top wire.
2) Fix the inner feet of the coupling and move the outer feet so that the eccentricity of the two center lines is zero.
3) After the above two methods are repeated several times, the coupling can be in a good alignment state.
The main technical requirement for coupling assembly is to ensure the coaxiality of the two axes.Excessive coaxiality errors will cause additional loads on couplings, drive shafts and their bearings. As a result, it will cause machine vibration, premature bearing wear, mechanical seal failure, and even fatigue fracture accidents.
