SwRI Information

Home

	A radioactive tracer wear test is conducted on a large hydraulic pump to determine the sensitivity of piston and slipper wear to pressure, displacement, and temperature. Irradiated parts are installed in a pump using remote manipulators.

Hydraulic component wear significantly affects:

• Performance

• Service life

• Maintenance

Extreme temperature gradients can result in component failures. Advanced instrumentation and sophisticated techniques at Southwest Research Institute (SwRI) address these reliability issues. Radioactive tracer technology measures component wear, in real-time, in pumps, injectors, and other components.

For more information about our hydraulic systems design and development and component wear capabilities, or how you can contract with SwRI, please contact Glenn Wendel at gwendel@swri.org or 210-522-2622.
