As people become more interested in diving, exploring underwater ancient cultural relics, national marine geographical exploration, the latest trend of underwater wedding photography, etc., underwater cameras are widely used in undersea lighting, thus driving the development of underwater photography lights.

Underwater photography lights are used in environments that are several meters or even dozens of meters underwater, so the lights are required to have extremely good sealing and high pressure resistance.

So how to test its sealing, that is?Underwater photography light airtightnessHow to detect it?Here are the answers for you.

Below, Hirays Technology will show youUnderwater photography light sealing testcase.

Customers require that their product, the underwater photography light, can withstand a pressure of 300Kpa, which is a pressure of 30m water depth.

Equipment used for air tightness testing: HC classic series air tightness detector

Testing method: Using the finished product testing method, according to the shape and structure of the photographic light, a sealing ring + mold is used to seal the product to be tested, so that it forms a sealed cavity during testing.

Place the underwater photography light into the mold for testing.The test pressure is 300 Kpa , the maximum allowable leakage is 50pa. The air intake time is 10s, the pressure stabilization time is 10s, the test time is 8s, the deflation is 8s, the quantitative air intake is 5s, and the partial pressure time is 5s.

As a result, the equipment automatically determines that if the leakage value does not exceed 50pa, the test product passes the sealing test, otherwise it fails, and the test product is a defective product.
