Underwater lights, fountain lights, and wall washers are all protective equipment used directly in water or in frequent contact with water.Since they are placed in water and need to withstand a certain amount of pressure, the waterproof performance requirements for these products are very high.Usually the waterproof level of this type of product is IP67 or IP68. If its sealing is not good, it will affect its normal use and even cause the risk of leakage.For the sealing test of underwater lamps, in addition to testing the precision of its structure, corresponding sealing testing is also required.Hirays Technology has been committed to the research and development of sealing testing equipment, and this time we will analyze the sealing testing of underwater lamps and fountain lamps, hoping to be helpful to you.

1. Analysis of the difficulties in sealing detection of underwater lights and fountain lights

1. The appearance of underwater lights is generally made of highly precise stainless steel. The appearance is similar to that of some geographical lights. It has high-quality waterproof joints, complete silicone rubber seals, arc-shaped multi-angle refraction reinforced glass, waterproof, anti-leakage, and corrosion resistance;

2. The fountain lamp has a larger appearance and there is a longer connecting wire behind the lamp. Its airtightness needs to be taken into consideration when testing.

3. The sealing test of underwater lights and fountain lights needs to overcome the obstacles caused by the appearance, not only to achieve non-destructiveness and safety of the test, but also to achieve the accuracy of the test results.

2. Analysis of the sealing test process of underwater lights and fountain lights

1. Both underwater lights and fountain lights have one characteristic, which is that they are relatively high-precision and have no obvious air outlet.Inspection requires the use of molds to assist, and there are connected wires behind the two, so Hirays has customized special molds for them. The molds have one feature. In addition to being able to place the test items, there is also a groove to place the wires. During inspection, the upper and lower molds can be closed, making the inspection environment better;

1. When testing underwater lights and fountain lights, the pressure when they are working in the water should be considered, and relevant parameters should be set on the instrument according to the situation, and changes in parameters on the instrument should be observed during testing.After setting the parameters, press the start button to close the upper and lower molds. The conduit connected to the instrument inputs gas of a certain pressure into the mold. When the parameter value is reached, the supply is automatically disconnected. At this time, the instrument will judge whether the sealing performance of the product is qualified based on the leakage value of the detected product;

3. If the leakage value of the tested product is greater than the corresponding parameter value, it proves that the sealing performance of the product does not meet the sealing standard, and the product is unqualified; if the leakage value of the product is less than the corresponding standard, it proves that the sealing performance of the product passes the standard, and the sealing performance of the product is qualified.
