Common Faults and Troubleshooting Methods for Helium Mass Spectrometer Leak Detectors
Publishdatea：2019-09-26 Views：128
Based on feedback from NOY customers on the helium mass spectrometer leak detector, the following table provides a reference for common faults and troubleshooting methods with a high failure rate during operation:
|
Category |
Fault Symptom |
Inspection and Analysis Method |
|
Power Supply |
Leak detector does not run after power-on |
Check whether the power outlet has AC 220V; Check whether the power connection is secure; Check whether the power switch outputs 220V; Check whether the fuse is blown |
|
No display after power-on |
Check whether the display module cable connection is loose |
|
|
Mechanical Pump |
Display is on after power-on, but the mechanical pump does not run |
Check whether the mechanical pump switch is turned on; Check whether the mechanical pump power cable is securely connected |
|
Abnormal noise from the mechanical pump |
Check all connection clamps on the mechanical pump; Check whether the leak test port is sealed; Check whether the mechanical pump fan guard is deformed; |
|
|
Mechanical pump not OK |
Check for large leaks; Check whether the mechanical pump oil has solidified |
|
|
Ion Source |
Filament does not energize |
Check whether the molecular pump has completed startup; Check whether the ion source socket is loose |
|
Ion source repeatedly energizes |
Check the wiring sequence of the ion source socket for incorrect connection |
