Die verschiedenen Arten der Qualitätssicherung
Die hochsensiblen Lecksuch- und Schnüffelsysteme von BBS stellen sicher, dass die mit unseren ausgefeilten Fertigungsmethoden montierten Komponenten dicht sind.
Wir analysieren die Kundenspezifikationen und bieten verschiedene Methoden zur Anbindung des Lecksuchsystems an andere Produktionsanlagen an, von voll- oder halbautomatischen Systemen bis hin zu einer manuellen/Batch-Version. Ganz gleich, wie Ihre Anwendung oder Branche aussieht, unsere integrierten Fertigungs- und Prüflösungen werden Ihren Anforderungen gerecht.
Sniffing Test
The product is filled with tracer gas. In case of leaks the tracer gas escapes through the leakage channel and is detected by a sniffer probe.
Spraying Test
First a vacuum is created in the product. The tracer gas is distributed over the product with a spray probe and can penetrate the leak.
Bombing Test
The method is used for products that cannot be connected directly to a leak detector. The product is placed in a chamber containing pressurized helium. The helium penetrates into the product. The actual test then takes place in the vacuum chamber, to which a helium detector is connected.
Accumulation Test
The product is placed in an accumulation chamber and filled with tracer gas. Gas which escapes through leaks is equally distributed throughout the chamber via fans. The leak detector measures the total leakage rate of the test item.
Hard Vacuum Leak Test
The product is filled with helium in an evacuated vacuum chamber. In case of a leak, the gas escapes through the leak and is measured by a helium leak detector which is connected to the vacuum chamber.
Pressure Decay Leak Test
The product is filled with air until it reaches its target pressure. The air supply is cut off to isolate the pressure. The pressure decay is measured over a specified period of time. In this way, the degree of leakage is calculated.
Acoustic Leak Testing
The test method is preferably used for pipe systems that cannot be accessed directly, for example because they are installed in a housing. Sound waves are sent through the test item by means of a transmitter. The sound waves recorded by the receiver are analyzed for characteristic changes in order to identify leaks.
Vacuum Decay Testing
The test is an efficient test method for detecting very small leaks. The test item is located in a vacuum test chamber. The connected detector measures the vacuum level in the chamber over a certain period of time and determines the change of the vacuum level in case of a leak in the test item.
