Vacuum Chamber-Type Helium Leak Detection Equipment is an advanced leak detection device that is based on helium mass spectrometry leak detection technology. It is specifically designed to detect minute leaks in various components or systems. The following is a detailed description of this equipment:

Equipment Structure

The equipment mainly consists of a vacuum box, a vacuum pumping system, a helium charging system, a helium mass spectrometry leak detector, and a control system.

Vacuum Chamber: A sealed container used to place the test piece. A high vacuum environment can be created inside the vacuum chamber to facilitate the detection of minute leaks.
Vacuum Pumping System: Includes a vacuum pump and related piping and valves, used to extract air from the vacuum chamber to achieve the required vacuum level.
Helium Charging System: Used to introduce a certain amount of helium gas into the test piece or vacuum chamber. Helium is an inert gas with small molecules that can easily penetrate through minute leak holes.
Helium Mass Spectrometry Leak Detector: The core component of the equipment, used to detect the amount of helium gas leaking from the test piece. It utilizes the principle of mass spectrometry to detect the presence of helium with high sensitivity.
Control System: Used to control the operation of the equipment, including automated control of vacuum pumping, helium charging, and detection steps.

Working Principle
