Cooling water
Check the amount of cooling water when using the water circulation pump. If
the water level is low, add water. Periodic replacement of cooling water is also
recommended.
Cooling water filter
This filter removes impurities from the cooling water. If the filter becomes
clogged with impurities, the water pressure may not rise appropriately. We
recommend changing the filter at periodic intervals.
Described below are the parts whose maintenance are required if using the
rotating anode type x-ray tube.
Target (2080A211/A411)
The target metal rotates at high speed to boost x-ray output. Pay close attention
and note any abnormal noise or vibrations, and if these occur please contact the
sales representative who you purchased the instrument from.
When contaminant (tungsten from the filament) from the electron gun (filament)
adheres to the target metal surface, you may observe characteristic x-rays from
the contamination, in addition to characteristic x-rays from the target metal. If
this happens, maintenance is required. Please contact the sales representative
who you purchased the instrument from.
Filament (2080A211/A411)
As electrons are discharged, the filament will become thinner, eventually
breaking the required circuit. Upon breaking, the filament will release a sudden
burst of electrons that can damage the target surface. To avoid this, we
recommend periodically changing the filament.
Ion gauge (vacuum gauge) (2080A211/A411)
Since the filament in the ion gauge may come loose after many hours of use, we
recommend changing the filament in the ion gauge at periodic intervals.
Rotary pump (2080A211/A411)
Check the oil level in the vacuum pump. If the oil level is low, add oil. We also
recommend periodic oil changes.
