Examination case of air tightness of swimming pool lamp

2018-12-25

Testing principle

Hairuisi sealing tester is a new ,high precision and non-destructive air leak tester .Our air leak tester adopts pressure principle and uses compressed air as the medium to detect leaks. It is a non-destructive testing instrument. The working principle is to apply a certain pressure to the inner cavity or outside of the product to be tested, then close the valve. After a period of stability, measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.This instrument is widely used in the sealing test of open products or sealed products with its high precision and full-featured features.

Underwater lamp is made of stainless steel material, which is used under the water and needs to bear certain pressure in the water. As the underwater light source, its waterproof performance is very important.

If its waterproof performance is not good, it will affect its normal use, and even lead to the risk of electric leakage .Hairuisi Technology has been making great achievements in the field of tightness inspection, and this time we will share the sealing test of underwater lights .Hope to give you some help in sealing inspection.

 

♦Product description

Underwater light also be called swimming pool light . The following picture is swimming pool light that Hairuisi Technology is going to test. We can see that there is no air hole in the product, so we need to make a mould for the product. The wire part of the testing product is not waterproof, so make a slot and put the wire part outside of the mold .This is also a major difficulty in the inspection program, which involves eliminating the influence of the wire on the overall waterproof detection of the camera. 

 

♦Testing process 

According to the special shape of underwater lamp, Hairuisi specially customized a mould for underwater lamp. The whole mould is cast according to the overall shape of underwater lamp. After the underwater lamp is put in, space of the mould can just be filled .The groove at the back of the wiring material is placed in the back of the mould, so that the closed space can be formed when the upper and lower moulds are closed.
