Bolt Bound Prevention?
By Mac MacCormack
On numerous occasions I have witnessed brand new pump skids where the electric motor was already bolt bound. Bolt bound is common in all industries. While conducting the field alignment portion of a precision shaft alignment training class at a chemical plant in southeastern Georgia, I had the opportunity to witness innovation at work to resolve this common issue faced by shaft alignment technicians. (In this particular plant thermal growth, due to the high process temperatures, would actually contribute to bolt bound situations as well.)
This is where the innovation of Mr. Theodore Moody Sr. and Mr. “Big” Larry Cribbs (names used by permission) comes in. As shown in the following pictures, their modifications to the motor bases makes getting out of a bolt bound situation quick and easy by being prepared ahead of time.
Mr. Moody has drawings for quite a number of pump skids. If any of the readers of this blog are interested, I will contact Mr. Moody and see if he would be willing to share.
