Test principle:

IPX8 test:

• By filling the tank with compressed air and increasing the water surface pressure, the pressure in the water increases synchronously, thereby simulating different water depth environments.

Positive pressure leak test:

• First place the sample in a pressurized environment, if there is a leak, the gas will enter the inside of the sample, thereby increasing the internal pressure.After a period of pressurization, the sample is submerged underwater; Then the compressed air is released to form a pressure difference inside the sample, and the internal gas will be discharged to form continuous bubbles in the water. The leak point is where the air bubbles come out.⁵

Negative pressure leak test:

• Submerge the sample directly into the water, and then evacuate the tank, so that the pressure inside the sample shell is greater than the outside. If there is a leak in the sample, you can see bubbles coming out of the leak in the water.⁶

Product outline:

This visual leak detector features advanced negative pressure detection, with a maximum negative pressure of up to 8 meters, making it suitable for leak detection tasks in various complex environments. The device is designed with a pneumatic cylinder lid, ensuring convenient operation and allowing users to quickly open the equipment for maintenance or adjustments.

• The test container is made of acrylic material, which is convenient for users to observe and record⁷.
• Built-in high-precision pressure sensor, which can display internal pressure changes synchronously.
• The tank cover is connected with a mechanical safety valve (not controlled by the software). If the set pressure exceeds the set pressure, the safety valve will release the pressure directly to ensure the safety of users.
• Controller: 7-inch touch screen + PLC, using Yuexin self-developed software, which can be switched to multiple languages⁸.
• Protection measures: short circuit protection,overpressure alarm.
• If the user needs to provide an external power supply for the sample, we can open a hole in the lid and provide a locking device (wire diameter <15mm).

Standard features:

Working scene:

Used for detecting leaks in pipelines, pressure vessels, heat exchangers, and comparable equipment, visual leak detectors are vital in high-precision environments. They serve as critical tools in manufacturing, equipment maintenance, and quality control, significantly enhancing leak detection's speed and accuracy.

Remark:

1 The pictures in this document are for customer reference only, and there may be color differences between the actual model and the pictures.

2 This document only lists some test standards, which does not mean that other test requirements and standards cannot be conducted. Welcome to communicate and discuss with us.

3 One test only at the same time. The next project can be only carried out after the current test is completed. In addition, we can provide multi-functional customized test solutions according to user requirements.

4 The formula of the corresponding relationship between pressure and water depth: P=9.8d (Unit :kPa,m).

5 Sometimes there are gaps on the surface of the product's shell, but this part will not last for a long time or bubbles occasionally. Usually, the condition for us to judge whether it is leaking is: observe continuous bubbles.If the product is small and there is almost no space inside (such as lamp beads), the judgment standard is stricter:: that is, if there are air bubbles, it will be judged as leakage.

6 Negative pressure testing is suitable for testing samples whose internal pressure is higher than the external ambient pressure, or for quick testing (no inflation process).

7 It is necessary to avoid scratching the inner wall of the container by the sample, as scratches will affect the observation and video effects.

8 At present, only Chinese and English interfaces are supported; if other languages are introduced, the software can be updated remotely.

9 The time unit set by the factory is generally in seconds. If you want to extend the test time, you need to explain in advance.
