How to detect and eliminate loose mounting when aligning the pump and motor
Thread Content
I would like to ask the experts: how can we check whether any of the motor’s four terminals are loose when aligning it? The experienced teacher in the class told me to remove all the shims first. For a particular foot, I should insert a feeler gauge first, then tighten the other three bolts, and again insert the feeler gauge to see if there is any change in the readings; the amount of change represents the offset for that foot. Finally, make the four feet in sequence, and you’ll know. Regarding this method, it seems to me like I’m measuring the virtual value of the diagonal feet, so I don’t quite understand it. So I would appreciate everyone’s advice.
Our experienced teachers use a dial indicator attached to the foot that is to be inspected, following steps similar to those taught by your instructor, and make judgments based on the readings from the dial indicator. This method saves one step compared to what you learned, but it’s a bit more troublesome to operate as there’s a risk of accidentally hitting the dial indicator.
During the processing of the equipment base, the cutting quality inspection by the planer must meet the standards. Pumps from major manufacturers generally do not have such problems
Remove all the gaskets first! ! ! It’s more convenient to use a dial indicator.
