Introduction to Hirays Intelligent Sealing Detection System

Hirays Intelligent Sealing TesterIt is a new type of high-precision non-destructive testing equipment.It mainly uses compressed air as the medium to apply a certain pressure to the inner cavity or surface of the product to be tested, and then uses a highly sensitive sensor to detect changes in pressure to determine the tightness of the product to be tested.Because it uses compressed air as the medium, there is no secondary pollution to the product. At the same time, the detection speed and accuracy are better than water detection (air molecules are smaller than water molecules and the leakage speed is fast), so it can be implemented on a large scale in production lines.

At present, traditional sealing testers are divided into direct pressure type, differential pressure type, and flow type according to their sensor types.The traditional direct voltage tester has low precision and poor accuracy; the differential pressure tester has high precision, but has a small detection range (usually only 5Kpa), requires comparison standard parts, and is complicated to implement; to address the above problems, Hirays adopts the latest microchip technology and combines it with the technology independently developed by Hirays.“Intelligent pressure difference”Patented algorithm.In 2012, the first generation of intelligent testers was developed, which is comparable to differential pressure testers in terms of accuracy, and is superior to differential pressure testers in terms of stability and cost.

Introduction to system functions and features

The high-precision intelligent analysis control system is an innovative technology of Hirays Technology. It is used in the detection of air tightness testers and breaks through the technical difficulties in achieving high-precision detection in the air tightness testing industry.In addition, the high-precision intelligent analysis and control system has further promoted the process of realizing fully intelligent and fully automated testing of air tightness testers.Let’s take a look at the features of our high-precision intelligent analysis and control system below!

1. High precision

Powerful 32-bit processor and 24-bit AVD converter, plus patented“Intelligent pressure difference"Algorithm, test accuracy is equivalent to differential pressure type.Compared with the differential pressure type, the testable leakage range is larger, which is basically equal to the test range.

2. Al algorithm

The automatic learning function can identify the characteristic information of the sample to be tested, analyze the valid data of the sample information, automatically judge and identify the critical point of the leakage volume, and obtain the optimal process time parameters through the analysis of the critical value, which greatly improves the difficulty of getting started with the instrument for the first time.

3. Powerful testing function

The system comes with 2 pressure forms and 8 basic judgment methods, which can be combined into more than 20 test functions to easily cope with various working conditions and meet your various requirements! Stable, reliable, and efficient, it has built-in self-developed patented technology.“MT&"The pneumatic sealing valve island" greatly improves the test accuracy and speeds up the inflation speed. At the same time, large leaks have been detected during the inflation stage, saving the entire test time.

4. The testing process is simple and more versatile

There is no need for standard parts, no need to make two sets of jigs, no need to compare with standard parts, and elimination of deformation errors after multiple tests of standard parts.

5. More scalable

Modular design allows one host to control an execution module composed of multiple full-function valve islands according to requirements.Realize full-featured multi-channel testing including positive and negative pressure and indirect testing.

Hi-OS 2.0 adds 3 new basic test methods: volume judgment, flow rate judgment, and reverse judgment;

New features of Hi-OS 2.0: learning function, volume measurement function, rapid inflation function, super reset program, sensitivity self-test, critical audit function, exception log, pressure calibration compensation, and more intelligent human-computer interaction prompts.

This air tightness testing equipment from Hirays Technology has strong adaptability and high-precision testing functions, helping to achieve high-efficiency and low-cost production.At present, this equipment has been used in air tightness testing in many fields such as mobile phones, automobiles, batteries, home appliances, smart wearables, and audio.
