Problems solved by technology

[0016] Therefore, this method has the disadvantage of requiring a certain amount of expertise on the part of the operator in order to properly calibrate the leak detection system and / or seal the part under test
[0017] Also, when performing leak testing on components with small internal volumes, for minor leaks and / or components where stiffness (or flexibility) affects the accuracy of the results (deformation of components due to pressure changes can cause errors in leak measurement results) , this approach may be difficult to implement

Embodiment Construction

[0064] figure 2 is a very schematic representation of a detection system 20 according to the invention in a first application example, wherein said leak detection system 20 is Figure 1a to Figure 1c Used on cartridge 1 as described.

[0065] Thus, the system 20 includes:

[0066] - a test chamber 22 configured to accommodate the components to be tested, here the cartridge 1 (represented very schematically);

[0067] - means 24 adapted to vary the pressure in said test chamber 22;

[0068] - a measuring device 26 for measuring a physical quantity indicative of the level of leakage, such as a pressure gauge or a flow meter;

[0069] - an insert 28 (or connecting part) configured to cooperate with the area of ​​the cartridge 1 containing the permeable area.

[0070] Thus, the insert 28 is inserted into the suction tube 5 of the cartridge 1 via one end of the tube, while the other end of the tube is sealed by a sealing member, such as a cap.

[0071] like figure 2 As show...

Abstract

The invention relates to a system (20; 20 ') for detecting leaks of a component having a permeable region. 20 '), the system comprising: a test chamber (22, 22') configured to receive a component to be tested; means (24) adapted to vary the pressure in the test chamber and / or in the component to be tested; a measuring device (26) for measuring a physical quantity representative of a level of leakage; characterized in that the system (20; 20 ') comprises a main tube (30) configured to cooperate with the permeable region of the component, one end (30a) of the main tube (30) communicating with the permeable region, while the other end (30b) of the tube (30) is in communication with the permeable region in the test chamber (22; 22 ') is open to the outside.

Description

technical field [0001] The present invention relates to the field of systems for detecting leaks or for measuring tightness, and more particularly to leak detection systems based on the measurement of a physical quantity (eg pressure or flow rate) relative to the leak level. Background technique [0002] Indeed, it is necessary to be able to check the integrity of the product and / or to check the product for leaks and to be able to quantify said leaks. Products / components to be tested are eg electronic devices, mechanical components, containers, etc. [0003] Tightness is a key characteristic when a product is subject to strict external constraints and needs to meet specific operational requirements, such as impermeability to liquids (eg, water), absence of leaks that could degrade product performance, etc. [0004] More specifically, there is a specific type of product in which some parts must have a certain degree of compactness (for example, to remain compact at a depth o...
