Product characteristics and leak detection methods of Hongjin airtightness tester

 

q

The Hongjin airtightness tester adopts compressed air detection and pressure drop detection principle. Through the same intake volume, pressure regulation and detection, changes in gas pressure and volume are detected. Through a series of sampling, calculation, and analysis by the precision tester PLC, the leakage rate, leakage value, and the entire product testing process are obtained in just ten seconds. Mainly used in industries such as food, pharmaceuticals, medical devices, daily chemicals, automobiles, electronic components, stationery, and consumer electronics.

The Hongjin intelligent airtightness tester is a new type of high-precision non-destructive testing equipment. Mainly using compressed air as the medium, a certain pressure is applied to the inner cavity or surface of the tested product, and then high sensitivity sensors are used to detect changes in pressure, thereby determining the airtightness of the tested product. Due to the use of compressed air as the medium, there is no secondary pollution to the product, and the detection speed and accuracy are better than water detection (air molecules are smaller than water molecules, and the leakage speed is faster), so it can be applied on a large scale in production lines. The instrument has won unanimous praise in the market for its convenient operating interface and economical and practical cost-effectiveness. The functionality and performance parameters of the instrument can both be set to 1, meeting the needs of the vast majority of customers.

Product characteristics of airtightness tester
1. High precision: Adopting imported pressure sensors combined with high-precision calculation and calculation modules independently developed by the company, the detection accuracy is high, comparable to the accuracy of differential pressure sensors, and has a larger detection range compared to differential pressure sensors.

2. Algorithm/human-computer interaction collection of testing product information: obtaining effective sample data links through big data analysis, and intelligently judging and automatically benchmarking the test data. Through a large amount of user feedback and the actual operation process and interface of the analysis instrument, it is convenient and simple, with progressive settings and extremely simplified operations; Password protection for operation permissions, humanized design for permission level detection, querying, and modification.

3. High stability/efficiency: The independently developed air path control components have improved ventilation efficiency, sealing, and stability. During the inflation/balancing/pressure holding stages, screening was conducted for both major and minor leakage states.

4.Non standard customization relies on strong independent research and development capabilities: We have developed multiple specialized airtightness comprehensive function testing equipment according to customer needs, providing a one-stop solution.

Three common leak detection methods for airtightness testers
1. Negative pressure test: Directly or indirectly vacuum treat the product, with the advantages of less interference and strong stability.

2. Positive pressure test: directly or indirectly inflate the product, with the advantages of simple operation and fast testing speed.

3. Differential pressure test: Comparing good products with defective ones, its advantages are less environmental interference and convenient operation.
