The fantastic underwater world is difficult for us ordinary people to visit in person, but through TV photos and other image data, we can see the wonderful underwater world; diving cameras not only truly reflect underwater scenes, such as the life of aquatic animals and plants, geological data on the seabed and river beds, archaeological discoveries, etc.At the same time, diving cameras are widely used in scientific research, military technology, sports, teaching, etc.Due to the particularity of the camera having to work underwater for a long time, it is necessary to consider whether the waterproof and airtightness of the camera (the airtightness test level must reach IP68 level) is qualified; if the airtightness of the camera is not good enough, not only will the function of the equipment be damaged, but the service life of the camera will also be affected, resulting in the loss of customers.At this time, a sealing detection equipment is needed to detect the waterproof performance of the diving camera.In this article, Hirays Technology explains how to test the waterproof function of a diving camera.

1. What is the traditional water immersion detection method?

Water immersion testing requires immersing the product in water. It takes a few minutes or more to test a product. Long-term and short-term immersion will indirectly corrode the product, which can easily lead to damage to the product appearance and internal components. Secondly, the subjective consciousness of the staff is used to judge whether the product is qualified, which can easily lead to unsatisfactory test results; and the speed is slow, which is not conducive to mass production.

2. What is the principle of waterproof and air tightness testing by Hiraysi Technology?

Hirays Technology adopts the detection principle of air pressure reduction method, uses air as the medium to detect products, and can detect small leaks in a short time.A sealed mold needs to be made according to the shape of the diving camera.Conventional cameras have high precision. After the mold is closed up and down, it can judge whether the air tightness (sealing performance) of the product can achieve the expected effect through the changes in air pressure inside the mold.

Diving camera parameter settings:

The waterproof level tested by this customer is IP68, the test pressure is 100kpa, the leakage limit is 0.1kpa, the air intake time is 4s, the voltage stabilization time is 15s, and the test time is 8s.The overall product is small and can be directly used as a push-down mold to facilitate the operator to pick and place the product.Adopting a dual-station design, two products can be placed at one time, which is fast, high-precision, and saves time and effort. Hirays Technology has always been adhering to one-stop solution to customers' sealing testing problems and perfecting every detail.Sealing testdetail.

3. What are the advantages of waterproof and air tightness detector?

The air tightness detector is used to test the sealing performance of products and has the following advantages:

1. High efficiency: Since the viscosity of water is greater than that of gas, the traditional water immersion detection method has fast air tightness detection speed and high efficiency, and does not require drying of the product;

2. Safe and pollution-free: Water immersion testing will cause pollution to the product, and it is easy to indirectly corrode the product, which is not conducive to the product object;

3. Simple operation: The air tightness detector is simple to operate, and you can quickly master the operation method without long-term training;

4. Low cost: Compared with helium leak detectors, there is no need for helium, only clean compressed gas; the traditional water immersion detection method takes about a few minutes to detect a product, while the air tightness detector only takes a few seconds to more than ten seconds to detect a product, saving a lot of manpower, material resources, time, etc.;

5. High reliability: The air tightness detector adopts a microcomputer control system inside. The microcomputer automatically judges the test results based on the set values, and the results are reliable;

6.  Strong compatibility: The air tightness detector is compatible with the MES system and can be customized according to customer requirements. At the same time, we have also developed a series of single-station, double-station high-precision leak detectors and multi-channel high-precision leak detectors to meet the needs of customers for mass production and batch testing;

Hirays Technology has performed air tightness testing on many types of cameras for customers. The types of cameras include: outdoor installation cameras, vehicle cameras, underwater mirrors, etc. If you have technical questions or want to know more about camera testing solutions.
