To prevent the failure of air tightness testers, it's crucial to understand how to determine if an air tightness tester is leaking. Let's delve into the detection principle of the air tightness testing machine. The principle of the air tightness tester's equipment involves precisely introducing compressed air at a controlled pressure into the test piece, then automatically shutting off the air supply. A relay accurately controls the duration of the air circulation balance, followed by a transformer that deactivates the balance function, with one end connected to the test piece and the other to a non-leaking standard part. The air tightness test is based on a high-precision differential pressure sensor connecting the supply of air between the test piece and the standard part, measuring the differential pressure between them within the specified time. By compensating for temperature, the actual pressure caused by the leakage of the test piece is obtained, allowing for the determination of whether the test piece is leaking. The integrity of the equipment's seal is a key factor in ensuring laboratory success. The method to check for air tightness involves immersing one end of the tube in a reaction device in water, touching the surface of the tube with your hand (or using a cup to heat it, if the equipment is not leaking, the gas in the container will deform upon heating, and small bubbles will escape from the tube mouth as the container water cools down, Wuxi energy storage waterproof, the air tightness test machine will create a water column inside the tube if there is no leakage. If the equipment is leaking, it will not produce small bubbles.

Airtightness Tester Inspection Method: Foam Solution Testing Method The foam solution testing method is a simple and convenient inspection method. Maintain the operating idea at a steady pace, and use neutralized foam solution with the airtightness leak detector to check for leaks in the vehicle's fuel gas pipeline. After the inspection, the foam solution should be disposed of immediately to prevent corrosion. It is required that no leaks are caused in all fuel gas pipelines, connectors, and lock nuts. If a leak point is found, it should be repaired using the tightening method before maintenance. If there is a persistent leak, mark the leak point. Replace the components according to the disassembly method. Leak inspection注意事项: Check for pipeline leaks while maintaining pressure in the pipe. Employees should pay attention to safety during inspection to prevent burns, bumps, and entanglement.

The necessity of airtightness testing in the new energy battery leak detection manufacturing industry. The key components of pure electric vehicles consist mainly of the motor, charging battery, and motor control, accounting for the vast majority. If the high-voltage working parts of electric vehicles, such as batteries and motors, are exposed to water, they may experience electrical short circuit failures. Therefore, the safety protection level of pure electric vehicles must exceed the IP67 waterproof level (the first digit after IP represents the dust protection level, and the larger digit represents the waterproof level). For new energy vehicles, the choice of hydrogen-powered and power lithium batteries to drive involves components with higher safety coefficients, particularly for the new energy battery packs. The airtightness testing of new energy battery packs is mainly divided into the testing of the upper and lower shells, and assembled parts. For the airtightness testing of the upper and lower shells, it is necessary to consider the leakage requirements after assembly, meaning the total leakage rate of the upper and lower shells must not exceed the leakage requirements of the overall battery pack product. Due to the inherent characteristics of new energy battery packs, the inflation pressure for the airtightness test of the battery pack cannot be too high. The company's basic principle is the pressure decay method, which means inflating a product with one gas and observing the pressure changes. This is divided into two scenarios: one where the product itself has an inflation hole, where we directly inflate the product and then close the pneumatic valve to observe the pressure change; if the pressure drops, it indicates that the product is leaking, and if it does not drop, it is good. The other scenario is where the product does not have an inflation hole, so we need to create a sealed cavity of the same size and shape as the product, essentially a mold, to ensure it fits the product as closely as possible, as this results in more accurate test results. Then, we inflate the cavity with one gas, and after closing the pneumatic valve, we check if the pressure has dropped; if it has, it indicates a leak, and the gas has渗入产品内部，if it hasn't, it is good.
