Product Description

Four Chamber Hydrogen Nitrogen Leak Detection Equipment

Product Introduction with Leak Testing Equipment:

The four-chamber hydrogen-nitrogen leak detection equipment is a specialized instrument that utilizes hydrogen and nitrogen as tracer gases to quickly and accurately detect leaks in workpieces by filling the vacuum chamber with the workpiece. Its advantages include high accuracy, high sensitivity (capable of detecting extremely small leak rates), high reliability (long-term stable operation), and good maintainability (low operating costs). This equipment is widely used in power plants, industrial applications, automotive refrigeration, and other fields to ensure product quality and safety.

Detection Process with Leak Testing Equipment:

1. Workpiece installation and vacuum box closing:

a.The operator places the workpiece into the vacuum chamber, connects the workpiece interface with the quick connector inside the vacuum chamber, and presses the start button.

b. Automatically close the vacuum chamber, and the detection cycle begins immediately.

Note: Grating protectors are installed on both sides of the vacuum chamber. When closing the vacuum chamber door, ensure that there are no objects interfering with the movement of the vacuum chamber in the closing area.

2. Vacuum chamber vacuuming and workpiece vacuuming:

a. Automatically vacuum the vacuum chamber until the vacuum level inside reaches the set opening pressure.

b. At the same time, automatically vacuum the workpiece until the vacuum level inside the workpiece reaches the set vacuum value.

3. Workpiece hydrogen nitrogen filling, medium leakage, and fine leakage detection

a. Automatically fill the workpiece with hydrogen and nitrogen gas at the set pressure until the pressure inside the workpiece reaches the set value.

b. Medium leakage detection: After the completion of hydrogen and nitrogen filling, the workpiece is automatically maintained under pressure, and whether there is medium leakage is determined based on the pressure drop value inside the workpiece:

If the pressure drop value inside the workpiece exceeds the set range, the leak detection process will be terminated, and the operation interface will indicate medium leakage and recover the gas.

c. After the completion of medium leakage, perform micro leakage judgment:

If the leak detector detects a hydrogen and nitrogen signal exceeding the set value in the vacuum chamber, it indicates that there is fine leakage in the workpiece, and a fine leakage indication signal is provided on the operation interface.

If the leak detector does not detect hydrogen and nitrogen signals exceeding the set value in the vacuum chamber, it indicates that the workpiece has passed the inspection, and a qualified signal is provided on the operation interface.

4. Vacuum chamber inflation

a. Automatically fill the vacuum chamber with atmosphere.

b. At the same time, the hydrogen and nitrogen inside the workpiece are automatically recovered.

5. Workpiece unloading

a. If the test is qualified:

The vacuum chamber door automatically opens. The operator disengages the joint inside the chamber from the workpiece interface.

b. If the test fails:

Press the confirm button manually and the vacuum chamber door will automatically open. The operator disengages the joint inside the box from the workpiece interface.

c. If an alarm occurs during the detection process:

Manually press the confirmation button. The vacuum chamber door automatically opens. Press the fault message prompt on the touch screen to clear the alarm status, and then retest the workpiece.

Note: For sorting products with leakage detected: 1. Take out one workpiece and leave one workpiece. 2. Continue testing one workpiece left in the chamber according to the normal operating method. This cycle continues until a specific leaking workpiece is detected.
