Underwater fountain lights are special lamps that act underwater and withstand a certain pressure. In order to ensure the precision of its structure, it is generally cast from stainless steel. As an underwater light source, its precision and sealing are very important.If its sealing is not good, it will affect its normal use and even cause the risk of leakage.The sealing test of underwater fountain lights will be judged based on its precision.This time, we will share examples of sealing testing of underwater fountain lights, hoping to be helpful to you.

1. Sealing test requirements for underwater fountain lights

The appearance of the underwater fountain lamp has a high degree of precision. It is surrounded by a special stainless steel casting shell, with a luminous body inside. The front is sealed with a transparent lampshade, and the overall sealing degree is high;

The underwater fountain lamp has a larger shape and a longer connecting wire behind the lamp. Its airtightness needs to be taken into consideration when testing;

This underwater fountain light operates in an environment 30 meters underwater, so this test needs to be carried out under a pressure of 300KPA and the test time is 10 seconds.

2. Demonstration of the sealing test process of underwater fountain lights

1. Due to the special shape of the underwater fountain lamp, Hairis customized a special testing mold for it. The underwater fountain lamp is placed into the mold and fits tightly. The corresponding air pressure value is set before the test begins. This test needs to test its waterproof degree within ten seconds under the condition of 300KPA;

2. When the test starts, press the start button and the upper and lower molds are closed to form a completely sealed space for the underwater fountain lamp. The instrument delivers clean and impurity-free gas to the inside of the mold through the conduit. It reaches 300KPA within the specified time. The instrument begins to judge whether the sealing degree of the lamp is qualified through the leakage value of the underwater fountain lamp in the mold;

3. If the underwater fountain light 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 fountain light is leaking, and the instrument test result will also show NG, which means the sealing test failed.If the tested underwater fountain light does not leak, the gas in the tooling mold will be in a constant state after inflation. The pressure value and leakage value displayed on the instrument are also stable. The instrument test result will display OK, indicating that the sealing test has passed.
