  • Importance of Leak Testing - SME

    Sep 09, 2020 · Ingress testing today is being used to help protect a variety of critical systems from dangerous contaminants. Ingress leaks occur when water, dust or other contaminants enter components through seams, holes or porosities. Leaks can cause fires, degrade autonomous vision systems and even create air-bag explosions.

  • The Advantages of Using Air Leak Testers | COSMO LEAK TESTER

    The Advantages of Using Air Leak Testers. Leak testing on production lines—such as for automobiles and gas equipment—has been, up to now, one of the processes causing the most bottleneck. A method often used in general is to seal air in WORK, submerge it in water, then visually check for bubbles. The cons of this method include that it is impossible to ensure that none are overlooked, a drying process becomes necessary, and it cannot be automated.

  • Pros And Cons Of Leak Detection Methods

    A Popular ChoiceClearly Seeing LeaksAnother OptionOne of the earliest electronic leak detectors to be introduced to the industry was the negative corona discharge model. The instrument works by creating a high voltage corona in the sensing tip. When the corona senses refrigerant, the device will sound an alarm. According to Seymour, early models of the negative corona discharge detector had some problems when they were first introduced. Large doses of refrigerant could “poison” the detector and cause it to malfunction. The other type of electronic detector is the heated diode model. The technology heats the refrigerant and breaks the molecules apart, creating positively charged chlorine or fluorine ions. The heated diode detector will sense these ions and set off an alarm. Both the negative corona and heated diode detectors have been improved over the years to prevent them from being too sensitive to large refrigerant leaks. In fact, TIF has made an improvement on leak detection with its ZX-1 Heated Pentode™ refrigerant detector. A...

  • Control Engineering | 7 Steps to Predictive Leak Testing

    Identify the need. In many situations, the need for predictive leak testing may be known right from the start. If the part, or one similar to it, has been in production, then it may have been leak tested in the past. Fixturing, sealing, volume fill. The physics of pressurizing a part with a test gas does not change by applying predictive testing; therefore, it is important that the part under test is properly fixtured and sealed. Equipment selection. The process or quality engineer responsible for the validity of the leak testing process should ensure that the equipment selected offers the tools to do predictive leak testing and validates that it is accurate and repeatable. Optimize fill rates and times. Efforts should be made to reduce the fill and stabilization time before applying prediction techniques to the analysis.

    Pressure decay leak testing is the most commonly used today. Its simplicity makes it easy to automate and to integrate into production/assembly processes. In simplest terms, the pressure decay test fills a pressure vessel with air until it reaches its target pressure, cuts the air source to isolate the pressure, and measures the decay (loss) of that pressure over a set period of time; any loss in pressure indicates a leak.
