Capacitor sealing testing equipmentThe Hai Rui Si air tightness testing equipment is suitable for various capacitor sealing tests,气密性检漏Fast speed and good stability.

The advancement of technology has made the fields involved more extensive and complex, and the quality requirements for products have become increasingly strict, just like capacitors and relays. Nowadays, there are also strict requirements for airtightness and sealing. So what exactly is itSealing detection equipmentIs it more advanced and reliable? To ensure the absolute sealing quality of capacitors, there is still a lot of knowledge involved, among which Haier Automation focuses on high-precision airtightnessSealing detection equipmentIn the field, we provide the most advanced solutions for major manufacturers in the long termSealing detectorThe device.

For small products such as capacitors and relays, air tightness testing is a difficult point because many products have opaque shells, many body seals without inflation ports, uncertain product shapes, and very small internal spaces. The production pace of products is very fast, and traditional soaking methods are simply not feasible here. However, Shenzhen Hairui SiSealing detection equipmentThe detection method uses gas instead of water detection;

We use gas attenuation method to detect whether the capacitor is sealed. Since the capacitor does not have an inflation port, we will make a precision sealing mold based on the shape of the capacitor, and then place the product inside the mold. The instrument will inflate the mold equally, and then calculate the leakage value to judge the quality of the product based on the leakage value. At the same time, the Hai Rui Si automated airtightness tester adopts a very small internal space (1.5CC), which can maximize the stability and reliability of the test. And equipped with imported high-sensitivity pressure 24 bit sensors, the detection accuracy can reach 1PA (a normal person can blow up to 15kpa with one breath, 1pa is 1/15000 of a normal person\'s breath), which can fully meet the waterproof test of electric toothbrushes. This detection accuracy can be objectively expressed, making it possible to detect large bubbles leaking from the needle hole every minute without error. In this way, the efficiency of waterproof testing has been greatly improved. Through the high-precision waterproof testing instrument of Hairui Si, the airtightness testing of capacitors and relays of various models has been detected, which helps manufacturers and other electronics companies to make products that are more in line with standards, making the products recognized by major customers, suitable for various complex environments, and more perfect.

Minimum resolution of pressure attenuation test is 1Pa

Minimum resolution for leakage flow test: 0.01ml/min

2、 Testing method.

Firstly, determine the testing standards, such as the sealing testing standard for capacitors and the IP67 waterproof testing standard for wristbands. This has international standard testing requirements, and the testing methods are relatively mature, so we will not introduce them in detail. Currently, most high-pressure airtightness tests are non-standard customized, and the testing requirements are determined by the customer. The testing standards need to be based on the product\'s usage environment, sealing requirements, and product characteristics through experimental testing. After analyzing the test data, the testing standards can be obtained. The conventional testing method is to inflate the product to a specified pressure, cut off the air pressure, and then detect the internal air pressure of the product. The detection data is collected and analyzed by a high-precision sealing detection system to calculate the leakage amount and obtain the leakage value. Compare the leakage value with the standard value to determine if it is qualified.
