How to make a coffee pot seal tester? You can use Hirays'sAir tightness detectorCarry out seal inspection on coffee pots

With the improvement of modern technology, sealing technology has become more and more perfect. In the small household appliance industry, there are many products that require sealing and waterproofing technology. Today we focus on the sealing and waterproofing technology of coffee machines. The most important thing for coffee machines is the waterproof protection of coffee pots, because coffee pots are in direct contact with water. If a seal leak occurs here, it will directly cause a poor customer experience.So how should the sealing test of the coffee pot be done?

Hirays Technology has a sealing tester, which is usually called air tightness testing equipment, air tightness tester, air tightness detection, air tightness test, seal test equipment, seal tester, etc. The sealing tester produced by Shenzhen Hirays Automation Technology Co., Ltd. is a high-quality air tightness leak detector made for various sealing products, especially for coffee pots. It is very experienced in seal testing.

Shenzhen Hirays Automatic Technology Co., Ltd. has many years of experience in waterproof testing. It has been committed to the waterproof testing of various products and the development and production of sealing testing equipment for more than ten years.Nowadays, a new generation of waterproof detection system has emerged and has successfully entered the market, winning unanimous praise from customers.

1. Principle of coffee pot seal detection and testing

Use a certain pressure and a certain volume of compressed air to inflate the product. If the product has an inflation hole, supply air directly to the product's inflation hole. After charging for a certain period of time, cut off the air supply, and use the pressure sensor inside the instrument to monitor the pressure changes after the product is inflated. If the product does not have an inflation hole, design a mold to wrap the product, and then quantitatively inflate the product surface through the mold, cut off the air source, and use the pressure sensor inside the instrument to monitor the pressure changes after the product is inflated. The two product test diagrams are as follows:

The parameters of Hiraysi air tightness detector are as follows:

Air supply pressure: 0.4~1.2MPa

Power supply voltage: 220v/50hz or 110v/60hz

Pressure adjustment range: -40~-0.5KPa, 5~150KPa

Pressure adjustment accuracy: 0.1KPa

Pressure test range: -80~150KPa

Pressure decay test minimum resolution 1Pa

Minimum resolution of leakage flow test: 0.01ml/min

2. Test method

First determine the test standards, such as coffee pot protection level test, IP67 protection standard.This is an international standard test requirement. The test method is relatively mature and I will not introduce it in detail. Currently, most high-pressure air tightness tests are non-standard customization. The test requirements are determined by the customer. The test standards need to be based on the product's use environment and sealing requirements. The product characteristics must pass experimental tests and the test data can be analyzed to obtain the test standards.The conventional testing method is to inflate the product, cut off the air pressure after it reaches a specified pressure, and then detect the air pressure inside the product. The detection data is collected and analyzed by a high-precision leak detection system to calculate the leakage amount and obtain the leakage value.Compare the leakage value with the standard value to determine whether it is qualified.
