Due to lack of experience, equipment alignment has recently encountered some problems. There is no problem in calculating the dial indicator data, but when it comes to adjusting the equipment, problems arise. 1. I first eliminate the upper and lower mouth openings, then the left and right mouth openings. I don’t know which order is correct? 2. Some people say that when aligning, you need to attach two bolts to the two couplings symmetrically and then align them. Is this correct? If yes, why? 3. I can’t understand the problem as shown in the picture. When I tried to eliminate the gap, I tried to use the No. 3.4 jacking screw to eliminate the gap (there are two jacking screws at each corner of the motor, of which the No. 1.2 jacking screw is fixed to limit the displacement direction of the motor). However, when the motor is jacked, the data on the two gauges on the end face of the coupling are getting smaller and return to the gauge (according to my idea, gauge A should become larger and gauge B should be smaller and return to the gauge). This is the case after several attempts. I hope the experts who have seen it can give me some advice, I would be very grateful! ! !
The smaller values of the two meters are different. The specific thing to use the dial indicator to correct is not the reading on the meter, but to use the meter to measure the difference. If you do not adjust it, make a circle to see if the difference has become smaller.
The principle of finding whom to look for first is the same! Generally, look up and down first and then left and right!
Add spacers to the four legs of the motor to prevent weak legs! It must be padded firmly!
Although the values on both tables became smaller when I was searching, they continued to decrease when I opened my mouth. To eliminate the mouth opening, you need to hit the meter back and forth several times. Is this normal? Sometimes the pump can be adjusted just once.

Haha, the previous reply has no guiding significance for you. If you want to understand it, you have to keep practicing and accumulating.

Just learn from an experienced master and you will understand.
first question: There is nothing wrong in the order of eliminating the upper and lower openings first, and then the left and right openings. The reason is that after eliminating the upper and lower openings, the upper and lower openings will not change when you eliminate the left and right openings. If you adjust the left and right first, the horizontal direction will change when you adjust the height, and you will have to redo the adjustment of the horizontal defense line. The second question: When the coupling is connected and then aligned, the two shafts can rotate synchronously, which can eliminate the deviation caused by wheel runout. The third problem: Simultaneous changes in the two tables indicate that the motor is moving horizontally without any deviation. This may be because there is a gap in your top wire or the top wire is elastic. It is recommended that you loosen the top wire No. 2, tighten the No. 1 top wire by hand, tighten the No. 4 top wire, and put a dial indicator on the foot to observe the movement. Under normal circumstances, do not use the top wires at both ends when adjusting the level. Only use the top wires at both ends to make appropriate adjustments when the distance between the couplings is inappropriate.
It is correct to use the No. 3 jacking screw, but remember to place the No. 2 jacking screw firmly against the motor to allow the motor to rotate.
