Lube Oil Systems

Fluid drives and bearings require dependable oil systems. The lube oil systems are critical components that can shut down plants for weeks or even months if they fail. The cost of unscheduled maintenance outages greatly exceeds the cost of lube oil systems.

TRI has been in the business of providing equipment for bearings and fluid drives for over 40 years. We understand that what is required for reliable systems with redundant backups. Consequently, TRI has provided many customers over the years with new or improved oil systems.

Geared Fluid Drives

Fluid drives can be built with an integrated gear set. The gears are used to increase or decrease the input speed.  The hydraulic coupling varies the output speed. This design allows for a small foot print, high efficiency and unsurpassed reliability.

Fixed Bore Bearings

Fixed Geometry Bore Bearings

Bearings that TRI work on can be classified into two main groups; Fixed bore bearings, or fixed geometry bearings and Tilt Pad Bearings. TRI can manufacture or repair all types of fixed bore bearings.

Over the years, we have worked with Pressure Dam Bearings, Elliptical Bore Bearings, Circular Bore Bearings and Multi-Arc Bearings. These bearings can also come with a wide variety of alignment and lubrication schemes.

Flush Cock Valve

Most Turbine-Generator Lube Oil Systems have lube oil supply piping that is fully welded. There is no opportunity for anyone to turn a valve that can shut the lube oil flow off. 

For duplex heat exchangers and duplex filters, a selector valve, sometimes called a double circuit valve, can be turned from one flow path to the alternate flow path. These valves are designed so flow is not blocked during the transition. 

Flush Cock Valves are different.  These valves can block or divert lube oil flow, but it cannot be operated when the lube oil system is in service or pressurized because it will leak severely when it is opened.
