Past Tech Notes

September 1, 2016

Since 1994, Dr. Mel’s Tech Notes have been issued from time to time. The Tech Note has evolved.  Since 2004, they have been distributed through email.  Prior to email, the Tech Note as sent out by fax.  When we first started sending out Tech Notes, the scope and length of the information was limited by the fax technology.  Most Tech Notes were brief, one page summaries of our latest projects. Now the Tech Note is distributed via email and published on the TRI Web Site (http://www.turboresearch.com/); the length and scope of the Tech Notes are no longer hampered by the delivery method.    Read the rest of this entry »

Bearing Repair Process

July 27, 2016

Electric generation companies make their money when it is hot outside. Consequently, they keep their machines running or available in the summer. Maintenance usually happens in the spring or fall…when the temperature is moderate.

Consequently, we have had some time at TRI to work on our web site. We undertook a big job to redesign it with a layout that will work devices of all size. We want it to look good on your desktop as well as your smart phone.

Our initial job is complete, but now we are adding more content for our customers.

Our latest addition is the Bearing Repair page. This page does more then just tell potential customers that TRI Transmission and Bearing Corp. repairs bearings. It is a bullet list of the steps bearings get when they come in the door. The list has been published so our customers understand what goes into a bearing repair.

When a bearing is sent to TRI during the summer, it usually means a machine is in an unscheduled outage. Unscheduled outages are expensive so it is critical that the repairs be done ASAP. When TRI goes to an expedited schedule, we work on the bearing repair 24 hours a day, 7 days a week. It’s important to us that the customer knows exactly what we are doing and how far along we are in the process.

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.
