As a common electrical appliance in the kitchen, induction cookers are often exposed to water, so the waterproof performance of induction cookers plays a very important role in their safety.Therefore, many manufacturers will conduct corresponding sealing tests on induction cookers when they leave the factory.Nowadays, as the demand for sealing testing in various industries has entered people's field of vision, sealing testing for induction cookers has become one of the factory audit standards.Hirays Technology has done a lot of research in the field of sealing testing, and has its own set of solutions for sealing testing of induction cookers. This time we will share the sealing testing of induction cookers, hoping to be helpful to everyone.
1. Requirements for sealing test of induction cooker
As a commonly used smart device at home, induction cookers are relatively large in size and difficult to seal. Its particularity makes sealing testing difficult; the customer requires vacuuming for testing;
(induction cooker)
The induction cooker is in a regular square shape. The front is the electromagnetic heating area and the operation display area, and the bottom is the heat dissipation port. When testing it, it is necessary to consider the non-destructiveness, stability, safety of the testing process and the accuracy of the testing results.Our Hirays sealing tester uses vacuum testing, which will not cause secondary damage to the product at all.
1. Demonstration of the sealing test process of induction cooker
1. Due to the large size of the product, we prepared corresponding tooling to place it during the inspection. The equipment is highly precise and has a corresponding air outlet at the bottom. This time we used a direct inspection method to connect the conduit to the induction cooker;

2. This time we will use the negative pressure test to test the tightness of the induction cooker. First, we set the test pressure value to be detected on the detector, then set the time and activate the test button. When the pressure of the induction cooker reaches the corresponding set value, the instrument will automatically stop working. At this time, the pipeline and vacuum environment will maintain the system pressure;

1. The air inlet valve closes automatically. At this time, you can observe whether the sealing performance of the induction cooker reaches the standard from the detector.
1. Advantages of using the Hirays sealing tester for testing
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. The patented technology independently developed by Hiraysi, "IVT pneumatic sealing valve island", greatly improves the test accuracy, ensures the stability of the instrument, and greatly improves the inflation speed.
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.
