What are the methods used in leak hunting in the vacuum system? (6 Key Techniques)

Leak hunting in vacuum systems is crucial for maintaining the integrity and efficiency of these systems.

There are several methods used to detect and address leaks, each tailored to specific needs and components of the system.

6 Key Techniques for Leak Hunting in Vacuum Systems

What are the methods used in leak hunting in the vacuum system? (6 Key Techniques)

1. Injection Detection Method

This traditional method involves evacuating the furnace and applying helium gas outside the furnace, typically connected to a helium mass spectrometer.

The system monitors for any helium that might enter the vacuum system, indicating a leak.

Helium is a small molecule and can easily penetrate through the smallest of leaks, making it a reliable tracer gas for detecting leaks in vacuum systems.

2. Nozzle Detection Method

This method is suitable for objects that cannot be evacuated, such as heat exchangers, water-cooled flanges, and electrical feedthroughs.

A leakage indicating gas, usually helium, is filled into the object to be detected.

A sensor or a helium mass spectrometer is then used to check for any gas escaping from the outside, indicating a leak.

This method is particularly useful for components that are not part of the main vacuum chamber but are critical to the overall vacuum integrity.

3. Inert Gas Leak Detection

For systems using inert gases, ensuring zero leakage from the gas supply system to the vacuum furnace is crucial.

Two commonly used methods for detecting inert gas leaks are the film (soap bubble) method and vacuum leak detection.

The film method involves applying a soap solution to suspected leak areas and observing for bubbles.

The vacuum method uses a vacuum gauge to monitor pressure changes, indicating a leak.

4. Maintenance and Preventive Measures

Regular maintenance and preventive measures are essential to minimize leaks.

This includes using helium leak detectors or residual gas analysis for locating tiny leaks.

Replacing temporary sealing compounds and regularly checking and replacing components like seals, valves, and pumps are also important.

Proper maintenance not only prevents unanticipated equipment downtime but also optimizes the performance and lifespan of the vacuum furnace, reducing the total cost of operation over time.

5. Monitoring and Testing

Regular monitoring of the vacuum system is crucial.

This includes measuring the pressure rise rate, which helps in detecting leaks by observing the rate at which the pressure increases when the system is closed and not operating.

Additionally, using a helium mass spectrometer leak detector or alternative methods like spraying acetone or ether at suspected leak points can help in identifying leaks.
