System Degassing
-
If new water and detergent has been added allow the system
to run for five minutes at 80% power. This allows the water in the cleaning tank to
properly degas (the water comes to oxygen equilibrium). The degassing process
removes unwanted air molecules from the cleaning tank, thus maximizing the
efficiency of the cavitation/cleaning process.
9.
Pump and filter system (Optional Accessory) -
The pump and filter system
’s
primary purpose is to filter out contaminants from the liquid in order to extend the
life of the detergent and lower operating costs. As agitation will hinder cavitation, it
is recommended that the operator not use the pump and filter during cleaning. If it is
absolutely necessary, the lowest flow rate permissible is recommended. The system
is fitted with a purge valve that enables operators to prime the syst
em’s pump in low
feed conditions. Some users will operate the system at 100% between cleaning
cycles or work shifts.
10.
Cleaning
- Place materials to be cleaned into the cleaning tank. Be sure that all
parts and components are fully submerged into the cleaning solution. Check to be
sure that no air pockets are present on the item(s) being cleaned, as the cavitation
process will only be effective where water co
ntacts the part’s surface. It may be
necessary to rotate the part while submersed to allow air to escape. Some initial
testing will help determine the proper settings for the optimum time and
temperature.
For
most
applications,
due
to
the
extreme
efficiency
of the unit, only 2 to 3 minutes of immersion time is required to thoroughly clean the
average part. These applications include removing machining oils and small
particles. For application involving baked on carbon or calcium and mineral
deposits, longer times and higher temperatures may be required.
NOTE: When first learning the capabilities of this system, do no leave
items
unattended in the tank for long periods. The system may damage the object if
it remains in the ultrasonic tank for extended periods of time. Longer
cleaning times can be used after thorough testing has been completed.
Do not place items to be cleaned directly on the tank bottom. The bottom is
essentially a high frequency speaker so contact may hinder the acoustic
propagation. Use UPC approved baskets or fixtures that are designed to minimize
acoustical losses and or damage to the tank bottom and the transducers. Heavy
items should always be suspended or placed on a work rest. In cases when a work
rest is required, consult UPC regarding a proper design for your application.
Do not attempt to clean aluminum in a caustic solution.
Do not use any chemical that is combustible. Chemicals not approved by UPC may
void warranty. Consult with UPC if unsure.
Do not use bleach or ammonia as a cleaning chemical.
