Solution & Implementation
Furmanite’s solution for TVA entailed assessing the vibration and alignment level of the pumps and bases and providing pressure grouting and pumping and machining services for the two pump bases. The pump bases were 16 feet 8 inches by 6 feet by 2 inches wide.
Initially, on-site Furmanite technicians laser scanned the bases to determine their combined tolerance level – off by 100 ths.
Prior to pumping the bases, Furmanite conducted acoustic testing to determine if there was a void. Then Furmanite technicians drilled holes and pumped the epoxy resin into the hole. The first base required two and a half units of epoxy resin. The second base took three units. The following day acoustic testing determined the levels were within tolerance.
After the bases were pumped, Furmanite determined that the machine level – where the motors and pumps meet – was out of alignment by 100 thousandth. They were then machined to create perfect alignment between the motor and the pump, which brought the bases back within tolerance level of 1 ths.
