It is an important work in the process of equipment overhaul that the lifting parts and shaft couplings are correct. The principle of finding the right is simple but very practical. Often used minicomputers on the pump alignment method with single table method, double table method and three method and so on. Either way, there is a common characteristic; in the horizontal plane than the vertical plane alignment error prone repeated strong, time-consuming and tedious calculation.

1 fixing lifting parts, couplings, motors, one side of the outer foot, moving the internal branch of the foot, until the motor and pump center eccentric line is zero. To ensure that the motor is not arbitrary, the fixed motor side of the foot, and the other side with a top wire to withstand.

2 fixing the inner foot of the coupling, moving the outer support foot to make the two center line eccentric.

3 or more, two methods repeated several times, can make the coupling in good alignment.
