Fluid Drive Upgrades

April 25, 2017

TRI has new tilt pad bearing designs for upgrades to the Size 270 Dual Circuit Fluid Drive. These bearings replace fixed bore pressure dam bearings and are essential for vibration control under high torque conditions.

The image below replace the bearing and the bearing housing on the output-outboard end of the fluid drive. It’s a 6 pad bearing with 2 thermocouples in the bottom pad and vibrations probes at 45° off of the vertical center-line.

Lift Oil Pumping System

March 21, 2016

TRI has recently completed a pair of lift oil pumping skids. They will produce 5 gallons per minute at 3000 p.s.i. The system will reduce the wear on bearings when the unit is on turning gear. The lift oil will also reduce the load on the turning gear and turning motor.
