Pressure Drop Testing Method: Inject a certain pressure of gas into a sealed workpiece, maintain pressure for a period (2~5 seconds), and check if the pressure drops. The price of metal bipolar plates, observe and calculate the pressure change to determine if the product has a leak (the entire process takes 5~25 seconds). This method is compatible with a wide range of gas tightness testing instruments and fixtures, suitable for both semi-sealed and fully sealed products. It can also evacuate air from the interior of a semi-sealed workpiece to create a vacuum for leak detection (for products requiring external waterproofing, it completely simulates the direction of water entering the product). Efficiency of Pressure Drop MethodlHigh, versatile, high detection rate, and non-destructive testing. The multi-channel airtightness tester can inspect multiple products simultaneously, which is the mainstream detection method for airtightness testers currently.
Airtightness Test Instruments, also known as Sealing Test Instruments, Waterproof Test Instruments, or Leak Test Instruments, are used to assess the sealing characteristics of a product or component. These instruments are also referred to as Waterproof Test Instruments or IP67 Waterproof Test Instruments, primarily used to determine if a product is waterproof and whether its waterproofing level exceeds the IP67 standard. The name of the Airtightness Test Instruments suggests that the testing is conducted using natural gas. Pneumatic valves are a prerequisite for the application of these sealing test instruments. Traditional waterproof testing methods involve using water, but this method has several drawbacks: 1. The operation is complex, requiring operators to submerge products in water, and some products need to be dried after soaking. 2. Oxygen levels are high, making it impossible to detect minor leaks. 3. The detection of leaks relies heavily on the operator's eyes, leading to potential misjudgments. 4. The testing process is slow, not suitable for rapid automation requirements. Due to these drawbacks, many manufacturers are opting for more intelligent, faster, and accurate Airtightness Test Instruments. Shenzhen Linglong Technology Co., Ltd. offers a range of six series of sealing test equipment tailored to different testing products and customer requirements. The Linglong Technology Airtightness Test Instruments can not only test the sealing of small products such as electric toothbrushes, watches, or speakers but also larger industrial products like car battery packs, high-voltage tower protectors, and large outdoor audio systems.
Airtightness Leak Detector
Gas Leak Detector (also known as Leak Detector, Airtightness Tester, Leak Detection Instrument, Dry Leak Tester, Leak Tester) Traditional testing of components for airtightness (also known as leakage) involves immersion in water or oil and visual bubble detection. The equipment is simple and results are直观, but the detection accuracy and efficiency are low, with significant human factor influence. It cannot achieve automatic quantitative leak detection, and it also brings adverse effects like dampness and rusting, impurities penetration, and the cumbersome process of surface water (or oil) attachment on the test pieces. Moreover, some products do not allow this method of testing, such as electronic and electrical components.
