With the improvement of modern technology, the sealing technology is becoming more and more perfect. There are many products that need to be sealed and waterproof in the small household appliance industry. Today, we focus on the sealing and waterproof technology of the coffee machine. The most important thing of the coffee machine is the tightness of the coffee pot, because the coffee pot is in direct contact with water. If the tightness is not good, it will leak, It will directly result in poor customer experience. That's the coffee potSealing testWhat should we do?
Harris technology has a kind of equipment seal detection equipment, which is usually called air tightness detection equipment, air tightness tester, air tightness detection, air tightness test, waterproof detection, waterproof test, waterproof detection equipmentSealing test equipmentThe sealing tester produced by Shenzhen Harris Automation Technology Co., Ltd. is a high-quality one for all kinds of sealing productsAir tightness leak detectorEspecially for the coffee potSealing test equipmentI have a lot of experience.
The company has many years of experience in manufacturing sealing testing equipment, and has been committed to the development and production of waterproof testing and sealing testing equipment for more than ten years. Now a new generation of waterproof detection system has been born, and successfully entered the market, won the praise of the majority of customers
1、 Coffee potSealing test equipmentTest principle
The compressed air with a certain pressure and a certain volume is used to inflate the product. If the product has air filling holes, the air is directly supplied to the air filling holes. After a certain period of time, the air supply source is cut off, and the pressure sensor inside the instrument is used to monitor the pressure change of the product after inflation; If there is no air hole in the product, the mold is designed to package the product, and then the product surface is inflated quantitatively through the mold, the air source is cut off, and the pressure sensor of the internal instrument department is used to monitor the pressure change of the product after inflation
The parameters of Hermes seal detection equipment are as follows:
Air supply pressure: 0.4 ~ 1.2MPa
Power supply voltage: 220 V / 50 Hz or 110 V / 60 Hz
Pressure regulation range: - 40 ~ - 0.5kpa, 5 ~ 150kPa
Pressure regulation accuracy: 0.1kpa
Pressure test range: - 80 ~ 150kPa
The minimum resolution of pressure attenuation test is 1pA
Minimum resolution of leakage flow test: 0.01ml/min
2、 Test method.
First of all, determine the test standard, such as coffee pot protection level test, IP67 protection standard. This is the test requirements of international standards. The test method is relatively mature, but there is no more introduction. At present, most of the high-pressure air tightness tests are non-standard customized, and the test requirements are decided by the customers. The test standards need to be based on the product's use environment, sealing requirements, and product characteristics through the experimental test, and the test standards can be obtained after analyzing the test data. The conventional test method is to inflate the product, cut off the air pressure after charging to the specified pressure, and then detect the internal air pressure of the product, collect the test data to the high-precision leakage detection system for analysis, calculate the leakage volume and get the leakage value. Compare the leakage value with the standard value to judge whether it is qualified.
