8. Working principle overview
Ring blower working principle:
Ring blower's impeller contains
numerous blades in its edge and it is special designed for a high air pressure.
When the impeller is rotating, air between the impeller would be accelerated
along the direction of the fan blades and due to rotating movement, after air
enters outside air layer, it comes back to the base of the fan blades due to
the effect of the differential pressure, the cycle will repeat several times to
make the air run spirally so as to increase the pressure. The air will expel
quickly because of the pressure there bigger than the pressure in the system
when the air runs through the outlet.
Operating principle:
Connect the suction unit with dental treatment unit,
take up saliva ejector from clip-on instrument holder of dental treatment
unit, and the suction unit will start automatically to suck foreign objects
attached with germina (such as oral secretion and dirty blood) into filter, the
filter will separate solid particles(such as teeth fragments, silver amalgam
particles) from dirty blood and oral secretion(please clean solid particles
inside the filter regularly).The filtered dirty blood and oral secretion will be
sucked into drain bottle, the air and water separator will separate the air
from dirty blood and oral secretion to ensure the air offered for ring blower
is clean and prevent the impellers from corrosive damage.
9. Safety precautions
1. When dental suction units working, please make sure that there will be no
goods can be touched t
he unit
.
2. Clean the filter regularly.
3. To change the electrical parts timely, but must turn off the power.
4. When to clean and maintenance the
suction units
, please to turn off the
power.
5. After setting up the suction units, do not move the unit too often, avoid to
affecting its working conditions.
6. To forbi
d the unprofessional person to use the suction unit, avoiding to
operating wrong.
7. When to maintenance the suction units, it must be some person who is
very qualified.
8.
Do not let the olds, children come into contact with the unit, avoiding
resulting harm.
9. When to use the suction units under knowing there will be result of harm,
to forbid using the suction units.
10. When the dental suction units are retired, the capacitor and electrical
components should be available to the local law and regulation.
