China Four Chambers Automobile Air Conditioning Compressor Hydrogen and Nitrogen Leak Detection System

Product Description

The Automobile Air Conditioning Compressor Four Chambers Hydrogen And Nitrogen Leak Detection System is a state-of-the-art device designed to detect gas leaks in automotive parts and other equipment. This system consists of four sealed test boxes and corresponding detection devices. By injecting a mixture of hydrogen and nitrogen gas, it can accurately determine if there are any gas leaks in the tested components.

This system utilizes hydrogen and nitrogen gas as the detection medium due to the high permeability of hydrogen, making it easier to detect even the smallest leaks. The gas in the test chamber interacts with the leak point on the surface of the component being tested. If there is a leak, it will be detected by the detection device.

Based on the basic leak detection principle of hydrogen and nitrogen, this system fills the workpiece with a mixture of hydrogen and nitrogen gas in a vacuum chamber. The hydrogen and nitrogen leak detector quickly and accurately determines the leakage situation of the workpiece with high precision.

Working Process

  1. Workpiece Installation and Vacuum Box Closing:
    • The operator places the workpiece into the vacuum chamber and connects the workpiece interface.
    • Automatically close the vacuum chamber, and the detection cycle begins.
    • Note: Ensure there are no objects interfering with the movement of the vacuum chamber during closing.
  2. Vacuum Chamber and Workpiece Vacuuming:
    • Automatically vacuum the vacuum chamber and workpiece until the desired vacuum levels are reached.
  3. Workpiece Hydrogen Nitrogen Filling, Medium Leakage, and Fine Leakage Detection:
    • Automatically fill the workpiece with hydrogen and nitrogen gas at the set pressure.
    • Medium leakage detection: Determine if there is medium leakage based on the pressure drop value inside the workpiece.
    • Micro leakage judgment: Detect hydrogen and nitrogen signals to determine if there is fine leakage in the workpiece.
  4. Vacuum Chamber Inflation:
    • Automatically fill the vacuum chamber with atmosphere while recovering the hydrogen and nitrogen inside the workpiece.
  5. Workpiece Unloading:
    • If the test is qualified, the vacuum chamber door automatically opens for workpiece removal.
    • If the test fails, manually press the confirm button to open the vacuum chamber door.
    • If an alarm occurs during the detection process, manually press the confirmation button to clear the alarm status.
    • Note: For sorting products with detected leakage, follow a specific cycle until a specific leaking workpiece is detected.
