Underwater lights are used under the water and need to withstand a certain pressure in the water, so they are generally made of stainless steel. As an underwater light source, its precision and waterproofness are very important.If its waterproofness is not good, it will affect its normal use and even cause the risk of leakage.For the waterproof test of underwater lamps, in addition to testing the precision of its structure, there is also a corresponding sealing test.Hirays Technology has always made great achievements in the field of sealing testing, and this time we will share the sealing testing of underwater lamps, hoping to be helpful to you.

1. Key points for sealing test of underwater lamps
The underwater lamp tested for sealing this time is made of stainless steel with high precision. It has a small and delicate appearance, beautiful appearance, and is similar to some geographical lamps. It has high-quality waterproof joints, complete silicone rubber seals, arc-shaped multi-angle refraction strengthened glass, waterproof, equation, anti-leakage, and corrosion resistance.

The particularity of underwater lights leads to relatively high testing requirements. During testing, not only must the sealing and non-destructive requirements be met, but the testing results must also be accurate.
2. Breakthrough in the difficulty of sealing detection of underwater lamps
1. In view of the special shape of the underwater lamp, Hirays specially customized an underwater lamp mold. The entire mold is cast according to the overall shape of the underwater lamp. After the underwater lamp is put in, it snaps just right. The rear-end connecting wires are placed in the groove at the rear end of the mold, so that the upper and lower molds can be closed to form a closed space during inspection;

2. Put the underwater lamp into the tooling mold and connect it to our instrument. There is a valve island, gas tank and other components inside the instrument as well as the program we have set. After the connection is made, press the start button when testing the wire.At this time, the upper and lower molds begin to close, and clean gas without impurities is filled into the mold. The instrument display will judge the waterproofness of the underwater lamp based on the gas saturation inside the mold.

3. If the underwater lamp is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined whether the underwater lamp is leaking, and the instrument test result will also show NG, which means the sealing test failed.If the tested underwater lamp does not leak, the gas in the tooling mold will be in a constant state after inflation, and the pressure value and leakage value displayed on the instrument will also be stable. The instrument test result will display OK, indicating that the sealing test has passed.
3. Underwater lamp sealing tester parameters
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.
