Concurrent Pressure Decay Leak Test of Paired EGR Valve Housings 

Problem/Goal: A manufacturer required a leak test system to perform a pressure decay test :

• On left and right sides of EGR valve housings
• To be conducted concurrently

Resolution: The TME Solution™ Leak tester was teamed with a custom designed test fixture. The pressure decay leak test is performed con­currently on both sides in a semi-automated test fixture that seals the housing outlets. pressurizes the housings. and tests for decay of the pressure inside the valve housings. The semi-automatic fixture is designed with two­hand anti-tie-down start mechanism for operator safety.
After completion of the leak tests. GOOD parts are automatically marked before the test parts are released by the fixture. In addition to the concurrent testing of paired housing sets. the test system is programmable to test one side or the other independently. 

Interpretation of test results:

• “Gross Leak” – A leak exits that exceeds the preset setting (a large leak)
• “Accept” – Indicates the part has passed the leak test
• “Reject” – Indicates the part has a small leak

Fixtures:
TME is known for its ability to design, and manu­facture special instrument and fixture solutions to solve specific testing problems.
Automotive products present a variety of testing. sealing and handling requirements including mark­ing. locking and multiple test procedures.

TM Electronics Instruments
TM Electronics offers two instrument choices: There are subtle differences between to the two instruments. Your TME account manager will recommend which will best fit your testing needs.

TME Solution:
The TME Solution has proven throughout the years to be a most reliable long lasting custom and standard leak test instrument.

Sensitive, repeatable, easily maintainable and reliable, the TME Solution can perform a variety of test types on product, including burst, occlusion, vacuum and pressure decay, crack, and differential pressure or vacuum.

Its touch screen menu driven operation allows the operator to control the test parameters, examine statistical analysis of results and download files easily.

TME Worker lntegra: A bench-top, high resolution leak test instrument with small foot print and user-friendly ease of operation.

The icon based touchscreen display provides easy, clear navigation through the wide variety of data handling and review screen.

Pressure changes as low as 0.0001 psi are detected from leaks in test parts.
