We have previously shared many cases of air tightness testing in the field of new energy vehicles, including air tightness testing solutions for new energy vehicle charging guns, car controllers, car wiring harnesses, and new energy vehicle power packs. These products all require special air tightness testing.Hairis Technology provides nearly a hundred mature air tightness testing solutions for air tightness testing in the field of new energy vehicles, and has also made major breakthroughs in testing technology.This time, we will share the air tightness test of the car charging gun control box, hoping it will be helpful to you.

Air tightness tester for car charging gun control box

1. Display of the appearance and detection difficulties of the car charging gun control box

1. The car charging gun control box is irregular as a whole and is made of black waterproof shell material. Just above it is the circular convex part of the docking device, and there are five connecting holes inside;

2. The bottom of the car charging gun control box is a component that wraps the internal components and is connected to the wires. Such a shape is difficult to fix during inspection, and it is easy to cause unavoidable damage to the car charging gun control box during inspection;

3. Then the combination of components will definitely lead to various non-waterproof problems, and this problem is also one of the difficulties in detecting the device.When testing the air tightness of the car charging gun control box, the traditional testing method is not suitable.

2. Breakthrough in detection difficulties of car charging gun control box

1. The car charging gun control box has a special shape. Hairis Technology specially uses a special mold and an air tightness tester that integrates a detector. During the test, the car charging gun control box is placed into the mold. There are grooves on the mold specifically for holding the wires, so that the wires will not affect the detection of the car charging gun control box during testing;

2. The upper mold has five round holes specially inserted into the car charging control box. During the test, the upper and lower molds are closed, and the round mouth of the upper mold will be embedded in the control box. During the test, the upper mold will input impurity-free gas into the controller. The detector will judge the air tightness of the mobile phone based on the air pressure inside the mold;

3. At this time, after the tooling connected to the mold is started, a certain volume of gas is injected into the car charging gun control box through the air source. When the detected air pressure is reached, the air supply is automatically cut off and the pressure is stabilized. The air tightness detection system of Hairis Technology will monitor the air pressure in the mold and determine the tightness based on the amount of leakage.

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent.

2. Patented technology independently developed by Hairuis,"IVT pneumatic sealing valve island", greatly improving the test accuracy, ensuring the stability of the instrument, and the inflation speed is also greatly improved.

3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions.

4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently, single selected and combined to meet various complex testing requirements.

5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn.

6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA&-1MPa) optional.The optional electronic pressure regulating valve can realize multiple sets of pressure sequential tests.

7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols.

8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches.

9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner.

10. Ultra-high stability and ease of use have passed the rigorous test of the market.

11. A variety of accessories are available, including inflatable bypass, quick connector, and standard leak hole. At the same time, the instrument supports third-party calibration and can issue a calibration report.
