Leak Detection Equipment For Motor Casing

Device characteristics:
1.It is suitable for dry leak detection of motor casing. It is automatically controlled from the beginning of leak detection to the display of leak detection results;
2.The system evacuates and fills the inspected workpiece with helium gas, and uses the vacuum box method to test the air tightness of helium mass spectrometry. The device determines whether the inspected workpiece is qualified or unqualified, and then recycles the helium gas in the inspected workpiece;
3. The automatic control system can adapt to 24 hours of uninterrupted operation every day;
4. The process technology is mature, and the helium mass spectrometry detection in the vacuum chamber can detect the overall leak rate of the workpiece;
5. The vacuum box is made of stainless steel, and the inner surface of the box is polished to reduce the amount of helium adsorption;
6. With the function of helium recovery, it can effectively reduce the consumption of helium. The recovery rate of up to 98%.
Leak Rate :1.0×10-6Pa.m3/S

DETAILS

Vacuum Box Method Detection Principle:

Motor Casing to be tested is directly connected to a mass spectrometer and put inside a chamber. Vacuum is created inside the part and the helium concentration in the chamber is raised to 100%. If a leakage is present, the molecules of helium migrate into the part and the leakage is measured by the spectrometer.

1. The high-pressure gas detects large leaks, and at the same time completes the strength detection;

2. Vacuum box vacuuming and background suppression;

3. The workpiece is evacuated and filled with helium;

4. Helium mass spectrometer detects sm all leaks ;

5. Helium Recovery.
