Vacuum Decay Leak Testing for Brake Housings การทดสอบการรั่วแบบสูญญากาศสำหรับเรือนเบรก

การทดสอบการรั่วแบบสูญญากาศสำหรับเรือนเบรก

อุตสาหกรรมยานยนต์ผลิตเรือนเบรก จำเป็นต้องมีระบบการทดสอบการรั่วแบบสูญญากาศสำหรับเรือนเบรกเพื่อให้มีการทดสอบการรั่วของการสลายตัวสุญญากาศ เพื่อกำหนดค่าของเรือนเบรก พารามิเตอร์

Problem/Goal:  Test brake housings for leaks
An automotive supplier manufactures brake housings. A leak test system was needed to provide vacuum decay leak tests on two configu­rations of the brake housings. The test parameters included a very long test time at a very minimal vacuum level.

Resolution: TME designed a custom test system comprised of a TME Solution single port Leak Tester, a test fixture that will accommodate either of the part configurations, and an external vacuum pump.

The fixture is comprised of a movable test plat­form on which the test part fits over a central base. By placing manual clamping pressure on the test part a seal is completed at the base of the housing.

The housing is then evacuated to the desired vac­uum level by the external vacuum pump and the test is run.

At the end of the extended test time (during which the external vacuum pump is turned off), the Solution test instrument will display the vacuum decay that has taken place during the test time. A green “Pass” light will indicate a good part and a red “Fail” light will indicate a leaking part.

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 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 down­ load 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.
