You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?
Alignment methods and requirements:1, check two feeler dial gauge or flange coupling the parallelism, usually with clearance between the both ends of the side instead of difference, in the circumferential direction every 900 measure, the maximum and minimum gap gap difference (Ab) less than or equal to 0.3 mm.2, the coupling flanges outside the park up and down, left and right four position to check whether they are in the same line, C less than or equal to 0.1 mm.When looking for a positive C, it will affect (a - b), finding the right (a - b) will affect the C, to balance each other. It's easier for an unskilled comrade to find C (a - b) first, and then find a positive one. Through the adjustment of the motor at the foot of the gasket thickness (Ab) and meet the requirements of C.Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition.It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:
For the first time, the pump and motor were placed on the base and not fastened (Cu Zhaozheng);Second times, the pump and motor have been tightened, the inlet and outlet flange bolts are not fastened;Third times, the pump runs 24 hours later.
