Chamber Type Gas Leak Detection System

2024-11-20

Gas detection technology has a wide range of applications, in which a typical gas leak detection system is used to detect the tightness of the workpiece to be inspected. The external structure of the existing gas leak detection system includes several main components, such as an organic frame, a tracer gas source, a tracer gas inflation valve, a pressure sensor, a detection chamber, a leak detection valve, a return valve and a gas leak detector.

One of the detection methods is the chamber type gas leak detection system. The chamber type gas leak detection technology generally uses halogen gas, hydrogen or helium as the tracer gas, fills the tracer gas into the workpiece to be inspected, and uses the gas leak detector to detect the concentration of the tracer gas outside the workpiece to be inspected. If the detected tracer gas signal exceeds the set value of the gas leak detector, it indicates that the workpiece is leaking.

Chamber type gas leak detection system can be divided into vacuum chamber type gas leak detection system and atmospheric chamber type gas leak detection system. The working principle and structure of atmospheric chamber type gas leak detection system include tracer gas source, tracer gas inflation valve, detection chamber, leak detection valve, return valve and gas leak detector. The workpiece to be inspected is placed in the detection chamber, and the workpiece to be inspected is connected with the tracer gas source through the connecting pipe. During detection, after the door of the detection chamber is closed, the tracer gas inflation valve connecting the workpiece to be inspected is opened, and the tracer gas is filled into the workpiece to be inspected. The pressure sensor detects that after the inflation pressure in the workpiece to be inspected reaches a certain value, the tracer gas inflation valve is closed, and the leak detection valve and return valve are opened at the same time. If the workpiece to be inspected leaks, the gas in the workpiece to be inspected will overflow from the leak hole and enter the detection chamber under the effect of differential pressure. The gas leak detector samples from the detection chamber and judges whether the workpiece leakage exceeds the standard according to the size of the tracer gas signal obtained.

For the vacuum chamber type gas leak detection system, there is a vacuum pump and a vacuum valve connected to the detection chamber. Before the tracer gas is filled, there is no need to vacuum the detection chamber for the atmospheric chamber type gas leak detection system.

The main features of the chamber type gas leak detection system are high leak detection accuracy, fast production rhythm and simple operation.

The sampling space of the chamber type gas leak detection system is the space of the detection chamber and the relevant pipe space connected with the gas leak detector. Before the tracer gas is filled in the chamber type gas leak detection system, the gas in the clean sampling space is the reference background, and the tracer gas signal left in the sampling space after detection is called background noise. The tracer gas in the background noise may leak into the sampling space from the gas leak detection system itself, or it is the residual accumulation of the previous detection. The background noise of the tracer gas will increase with the repeated operation of the system. When the background noise exceeds a certain level, it will lead to the failure of the leak detector to operate normally, and even lead to false judgment of the detection results. The existing technology cannot effectively eliminate the residual accumulation of tracer gas, and it is usually necessary to eliminate the impact of background noise through repeated empty machine operation. The equipment operation efficiency is low, resulting in energy waste.

Gas Hood Type Gas Leak Detection System

Gas detection technology has a wide range of applications, in which a typical gas leak detection system is used to detect the tightness of the workpiece to be inspected. The external structure of the existing gas leak detection system includes several main components, such as an organic frame, a tracer gas source, a tracer gas inflation valve, a pressure sensor, a detection chamber, a leak detection valve, a return valve and a gas leak detector.

One of the detection methods is the gas hood type gas leak detection system. The gas hood type gas leak detection system uses halogen gas, hydrogen or helium as the tracer gas, fills the tracer gas into the detection chamber (i.e. the gas hood), and uses the gas leak detector to detect the concentration of the tracer gas in the workpiece to be inspected. If the tracer gas index is detected to exceed the set value of the gas leak detector, it indicates that the workpiece to be inspected has leakage.

The working principle and structure of the above gas hood type gas leak detection system include a tracer gas source, a tracer gas inflation valve, a detection chamber (i.e. a gas hood), a workpiece connecting pipe, a leak detection valve, a return valve, and a gas leak detector. The backflow valve is connected with the gas leak detector, and the detection chamber is connected with the tracer gas source through the connecting pipe. After the door of the detection chamber is closed, the tracer gas inflation valve is opened, and the tracer gas is charged into the detection chamber. When the pressure sensor detects that the inflation pressure of the detection chamber reaches a certain value, the tracer gas inflation valve is closed. Open the leak detector and return valve. If the workpiece to be inspected leaks, the gas in the detection chamber (i.e. the gas hood) will overflow from the workpiece leak hole into the workpiece to be inspected under the effect of differential pressure. The gas leak detector samples from the internal space of the workpiece to be inspected, and judges whether the workpiece leakage exceeds the standard according to the size of the tracer gas signal obtained.

The main features of the gas hood type leak detection system are high leak detection accuracy, fast production rhythm and simple operation.

The sampling space of the gas hood type gas leak detection system is the internal space of the workpiece to be inspected, the workpiece connecting pipe and the relevant pipe space connected with the gas leak detector. Before the tracer gas is filled, the gas in the clean sampling space is the reference background of the gas hood type gas leak detection system, and the tracer gas signal remaining in the sampling space after detection is called background noise. The tracer gas in the background noise may leak into the sampling space from the gas leak detection system itself, or it is the residual accumulation of the previous detection. The background noise of the tracer gas will increase with the repeated operation of the system. When the background noise exceeds a certain level, it will lead to the failure of the leak detector to operate normally, and even lead to false judgment of the detection results. The existing technology cannot effectively eliminate the residual accumulation of tracer gas, and it is usually necessary to eliminate the impact of background noise through repeated empty machine operation. The equipment operation efficiency is low, resulting in energy waste.

Test Methods of Air Tightness Test Equipment for Testing Condenser of Auto Air Conditioner

2024-11-20

If we want to test a condenser of auto AC, a helium gas detection system or an air tightness test equipment is needed to do the test. But how does it works? Here are the methods of testing car condenser:

 

1.Large leak detection: After the vacuum holding chamber front door is shut down, the machine successively functions tough and great pumping of the vacuum holding chamber before the vacuum level inside the holding chamber reaches the set leak detection stress. Once the vacuum holding chamber is evacuated, the machine fills the test part inside the holding chamber rich in-stress gas of three.5MPa (downward changeable), after which keeps the strain, waiting around for the strain sensing unit of the system to ensure whether there is a huge leak. If there is a huge leak inside the check part, the machine will discharge our prime-stress gas inside the check part, close the suction control device of the vacuum holding chamber at the same time, and terminate the leak detection method. And right after filling the vacuum holding chamber into the environment, the proprietor presses the verification option, the entrance of the vacuum holding chamber will automatically available, utilizing the check part out, marking and putting it into the to-be-handled place. When the system fails to find a huge loss of the check part, it would automatically carry out the subsequent leak detection method.

 

2.Vacuum the test part: If no huge loss of the check part is available, the machine will release our prime-stress gas inside the check part and vacuumize the inside of the check part. Once the vacuum level inside the check part reaches the set stress worth, wait for the evacuation technique of the vacuum holding chamber to accomplish.

 

3.Vacuum helium detection: Once the evacuation of the vacuum holding chamber reaches the set leak detection stress, and at the same time the evacuation of the check part inside the holding chamber continues to be finished, the machine detects the helium sign inside the detection container and suppresses this sign to absolutely nothing. Then load the test part with 4.0Mpa (downward changeable) helium gas. Once the helium gas stress inside the check part reaches the set worth, the leak detector will detect the loss of the check part.

 

When the leak detector locates a helium sign that surpasses the set worth, this means that there is a tiny leak inside the check part inside the holding chamber and also the system will problem a leak alarm system. The proprietor presses the verification option, and also the vacuum holding chamber will automatically be opened up right after simply being loaded with the climate. After the proprietor divides the fast connector from the check part, the test part may be taken off and designated consequently.

 

When the leak detector fails to find a helium sign that surpasses the set worth, this means the detected check part has no loss. The program sends a signal that goes by the detection, and automatically functions the helium rehabilitation method in the check part.

 

4.Helium rehabilitation: After the assessment is completed, the helium inside the check part is sent back to the very low-stress helium aquarium through automated stress harmony. Once the helium stress inside the check part falls to atmospheric stress, the machine works with a vacuum pump to recuperate the remainder helium inside the check part. Once the stress inside the check part falls to the set worth, the helium recovery process is completed. Whilst recouping helium, the machine fills the vacuum aquarium with environment. Once the stress of the vacuum container rises to atmospheric stress and also the helium recovery process of the check part inside the holding chamber continues to be finished, the entrance of the vacuum holding chamber is automatically opened up and also the detection method is completed.
