| Cleaning craft |
| Cleaning
is to clean out the contamination on the surface of
workpieces including liquid and solid contamination
and to make the surface attain clean degree. Cleaning
process, the interaction among solution, pollutant and
the surface of workpieces, is a process of complicated
physical and chemical effect. Cleaning is relevant not
only with the property, category, appearance and adhesion
degree of the pollutant, the physics and chemistry property
and capability of solution and the material and surface
state of workpieces, but also with the condition of
cleaning, such as temperature, pressure, the accessional
ultrasonic vibration, outside force of machine etc.
Therefore, to choose a scientific and reasonable cleaning
craft must carry on the craft analysis. |

 |
Immersed
cleaning
Add cleaning solvent to the trough,
and immerse the things which will be washed to
clean. Because it only depends on the chemical
effect of solvent to clean, it has some disadvantages
like weak cleaning capability and long-time and
repeated cleaning.
|
 |
Whiff
cleaning
Install gas nozzles in the
trough, and spray to the things which will be
cleaned by gas. Pressure is more than 20kg/cm2.
|
 |
Cascade
cleaning
Spray the cleaning solvent
from the liquid phase on the side of trough and
use the stirring of liquid to clean. So its capability
is better than immersed cleaning. |
 |
Scrub
cleaning
In the trough, fix brushes
and support or tongs. While immersing in solvent
or humidifying, clean mainly by the friction between
brushes and workpieces. It will be effective for
the elementary cleaning.
|
 |
Ultrasonic
cleaning
Install ultrasonic oscillators
in the troughs and generate ultrasonic power which
equals thousands times of standard atmospheric
pressure. |
 |
Sprinkling
cleaning
Fix sprinkler pipes in the cleaning
trough, and spray cleaning solvent from gas phase
to the things for cleaning. Pressure is lower
than 2kg/cm2.
|
 |
Decompression
cleaning
Generate negative pressure in
the trough, which is better for solvent to immerse
into the gap in the components. With the ultrasonic
effect, cleaning effect will improve more. |
 |
Spraying
cleaning
Fix injection spray pipes in
the cleaning trough, and spray cleaning solvent
from gas phase to the things for cleaning. Pressure
is between 2 kg/cm2 and 20 kg/cm2. |
 |
Circumrotatory
bucket cleaning
Fix the slewing arrangement in
the trough. Circumgyrate the bucket and stir the
things to be cleaned at the same time. Always
use with cascade and ultrasonic cleaning. |
 |
Vibration
cleaning
Fix the vibration components
in the trough. Put in things for cleaning and
make them vibrate up and down. Always use with
cascade and ultrasonic cleaning. |
