Accurate Leak Detection Machine With Negative Pressure

Product size and material:

• External dimension: Approx W 1100×D 650×H 1250 (mm)
• External material: 304 stainless steel
• Internal dimension: Approx φ500×H 500 (mm)
• Internal material: Acrylic

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:

Compared with ordinary leak detection test devices, this air pressure visual leak detection tester has added negative pressure detection technology, which can detect small leaks in the sealing system in a short time. This is particularly important for situations where time is of the essence.

• 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:

Installation requirements:

• Aisle: Before the equipment enters the factory, please confirm that the space in the aisle, elevator, laboratory, etc. of the factory area is sufficient for the equipment to pass through.
• Water source: Please prepare clean water source.
• Air source: Please prepare a compressed air source with an output pressure of 0.6-0.8 Mpa¹⁰.

• The room needs to reserve a drain, and the bottom of the machine can be connected to a water pipe for drainage.

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.

10 The user needs to prepare an air compressor in advance (recommended gas storage capacity > 60L). If you need us to buy it on your behalf, you need to explain in advance.
