Helium Mass Spectrometer automatic mobile helium mass spectrum leak detector
1. Performance description
series leak detector is a fully automatic mobile helium mass spectrum leak detector, mute wheel design, suitable for many harsh vacuum industry.
Using helium mass spectrometry and inverse diffusion principle, using 180 ° inhomogeneous magnetic field and automatic control technology. Automatic helium peak scanning, automatic calibration and automatic range switching are realized.
It has the characteristics of short start time, fast operation speed, high detection sensitivity and strong anti-interference ability.
Helium Mass Spectrometer automatic mobile helium mass spectrum leak detector
2. Performance characteristics:
1.Unique gas path design, can avoid dust into the instrument interior
2.Multi-mode function input, output, easy to connect a variety of automation equipment
3.Double iridium ion source, strong antioxidant capacity and long service life
4.The machine is effectively separated from the circuit, avoiding the interference of temperature, electromagnetic field and so on, which makes the leak detector run more stable and reliable
5.APP: WiFi connection,use mobile phone APP remote over-control leak detector to start, stop, zero. Real-time monitoring leak detector shows leakage rate.
6.With automatic zero, automatic range switching function.
7.Large leak detection function: The pressure can be preset. When the pressure is evacuated, if the preset value cannot be reached, the leak detector will automatically alarm.
8.Multiple measurement unit selection, real-time update of detection data, direct output to generate Excel tables.
9.The machine has automatic alarm detection function, which is convenient for users to check and maintain the machine.
10.Equipped with a 7-inch color touch screen, the Angle can be rotated, and the operator can adjust the direction according to comfort.
11.This machine adopts metal keys, durable. one-click automatic emptying.
12.Leak detector custom software, can be written according to customer requirements
13.Molecular pump Equipped with Pfeiffer splitflow 80 or 90(Imported from Germany)
4. Leak Detection
Negative pressure method
Vacuum the sealed chamber inside the inspected product Apply helium gas on the outer surface of the product under inspection Leak detector detects changes in helium content inside the workpiece The precise location of the leak can be realized
Positive pressure method
The sealed chamber is filled with helium under certain pressure. When a leak occurs, helium leaks through the leak through the surrounding atmosphere . Detection of helium concentration increments in surrounding atmosphere by suction method The precise location of the leak can be realized.
Back pressure method
Place the inspected product in a pressurized helium chamber for a certain period of time Remove the residual helium from the surface Put the inspected product into the leak detector connected with the leak detector;Take the maximum leakage rate for a certain time.
Helium injection method leak detection process
Helium injection test standard:
"Helium Mass Spectrometry Vacuum Leak Detection Method",
"Helium Leak Test" After assembling the workpiece, use the corresponding tooling to connect the workpiece to the leak detector. After confirming that the connection is OK, press the "Start" button of the leak detector, and the leak detector will enter the evacuated leak detection state. Observe that the background value displayed on the leak detector screen reaches 4.0×10-10Pa·m 3/s. Use 99.99% or 99.999% helium gas to detect the suspected leak point of the workpiece. For each suspected leak point, spray helium for 1 second and observe the background value of the leak detector for 3-5 seconds. Observe whether the background value of the leak detector is increased or whether the leak detector has alarm output.Follow Step 5 to detect other suspicious leakage points. Helium injection test sequence is from top to bottom, first confirm the big leak point, After the test, press the "Stop" button of the leak detector first. After the standby screen of the leak detector screen appears, remove the workpiece. Suction method leak detection process
Suction test standard:
"Helium mass spectrometry Positive pressure Leak Detection Method",
"Pressure vessel weld helium mass spectrometry gun cover box leak test method" After assembling the workpiece, use the corresponding tooling to fill the workpiece with a certain pressure of 99.99% or 99.999% helium. After confirming OK, connect the suction gun to the leak detection port of the leak detector. Press the "Start" button of the leak detector, and the leak detector enters the evacuated leak detection state. Observe that the background value displayed on the leak detector screen reaches 5.0×10-8Pa·m About 3/s. Relatively stable state. Helium gas is used to detect the suspected leakage point of the workpiece. The suction gun is used from the bottom up, 1-3mm away from the surface of the inspected part, and the moving speed is not large Test at 10mm/s to detect the helium concentration increment in the atmospheric environment around the tested product. Follow Step 4 to detect other suspicious leakage points. First confirm the big leak point, handle it well, and then detect the small leak point After the test, press the "Stop" button of the leak detector first, and remove the suction gun after the standby screen appears othe leak detector display.
