Positive Pressure Leak Test for Industrial Samples with Visual Leak Test Machine

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

Product introduction:

The specialized Leak Detection Visualizer, incorporating air pressure methodology, is meticulously crafted to accurately identify leaks within a wide range of systems and individual elements. Its enhanced visual interface expedites the process of leak source identification, ensuring both promptness and precision, making it an indispensable element in maintaining quality standards and preserving the reliability of products.

• The test container is made of acrylic material, which is convenient for users to observe and record⁶.
• 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: 4-inch touch screen + PLC, using Yuexin self-developed software, which can be switched to multiple languages⁷.

Notes:

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 It is necessary to avoid scratching the inner wall of the container by the sample, as scratches will affect the observation and video effects.
7 At present, only Chinese and English interfaces are supported; if other languages are introduced, the software can be updated remotely.
8 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.
9 The photos may not match the actual ones, and are for user reference only.
