Thoroughly agitated
July 1st 2008 Guyson International has
supplied a Kerry Microsolve
M250/2M mono-solvent
ultrasonic cleaning system to Bifold
Fluidpower – a manufacturer of
hydraulic and pneumatic stainless
steel directional control valves,
hydraulic solenoid valves,
pneumatic solenoid valves and filter
regulators. The products demand a
critical level of cleaning as many are
used in oil and gas industry
hazardous environments.
The cleaning system is used for
the removal and precision stain-free
cleaning of oils and lapping
residues from stainless steel, brass
and monel valve components.
Many hydraulic and pneumatic
components have internal galleries,
screw threads and internal holes
that could trap particulates. To clean
them thoroughly, agitation can be
effected deep inside components
by using ultrasonics.
Stainless steel mesh component
baskets are lowered into unit one by
an Autotrans single-axis transporter.
The controlled lift of parts ensures
minimum disturbance to solvent
vapour, minimising expensive
losses. It also cuts any OEL
(Occupational Exposure Limits).
The stage one tank is fitted with
base mounted ultrasonic
transducers powered by a Pulsatron
series 300 generator at 38 kHz. The
second stage is electrically heated,
allowing the solvent to boil. The
resulting vapour rinses the
components, which are dried by a
dwell in the freeboard zone.
Solvent vapours are condensed
by the primary reflux cooling coils
and collected in the integral distillate
trough. The solvent passes through
a dual purpose gravity or molecular
sieve type water separator and
returns to the stage one ultrasonic
tank, displacing contaminated
solvent into the boiling sump.
Distillation and filtration of the
solvent, ensures the ultrasonic tank
cleanliness is maintained. More articles from Guyson International Ltd: |
