Ultra-large Product Vacuum Chamber Helium Leak Detection Equipment

Ultra-large Product Vacuum Box Helium Leak Detection Equipment

Product introduction:

This is a helium leak detection device for a very large product vacuum box. The vacuum box helium leak detection recovery system is adopted. Helium is recycled to reduce costs. It detects the overall leak rate of the workpiece, and has high leak detection accuracy. The system is mature and reliable, and the layout is reasonable. It is suitable for leak detection of various products.

Basic working principle:

According to the basic leak detection principle of helium leak detection, helium is used as the tracer gas. Fill the workpiece with helium gas in the vacuum box, and then use the helium leak detector to quickly and accurately detect the leakage of the workpiece with high precision.

Features：

1. Quality assurance of core components, the core components of the system are subdivided into individual units based on the principle of modularity. The core components of each unit are imported components. It can ensure the precision and high stability of the equipment.

2. The vacuum box is made of stainless steel, and all surfaces are specially treated after machining. The leak-tightness of the vacuum box itself is detected by the vacuum helium spray method. The connecting pipes in the box are hoses and quick connectors, which can realize quick loading and unloading.

3. The automatic helium clearing function is a helium clearing method used by the high-precision leak detection system. At the same time, it can ensure the stability of the detection system, and can avoid the impact of a large amount of helium on the leak detector, and prolong the service life of the system.

4. The specially designed sealing fixture adopts two seals between the fixture and the workpiece, and the sealed space formed between the two seals is connected to the vacuum pump through an evacuation pipeline.

5. Convenience of system operation, the system adopts process automation technology, combines process equipment with electrical automatic control technology, and automatically controls the entire workpiece detection process by PLC and touch screen.

6. The system guarantees the quality of the product. The entire inspection process is automatically completed by the system, without the operator's judgment and execution, avoiding the influence of human factors on the inspection results, and ensuring the consistency, objectivity, stability and repeatability of the operation.

Basic functions:

The operator connects the workpiece interface with the quick connector in the vacuum box. After the door of the vacuum box is closed, the system can automatically complete the gross leak detection, evacuating, helium filling, fine leak detection, helium recovery. The production cycle is fast and the leak detection accuracy is high.
