Precision Cleaning System Meets High Cleanliness CAT
Specification
This CM System is designed for
precision cleaning a wide range of cast iron components to meet a stringent
CAT cleanliness specification. To achieve this goal the system had to
adequately, easily, and consistently remove manufacturing residuals contaminants
from exterior surfaces and interior recessed areas (including blind holes).
The process required a combination of high volume turbo/agitation/flushing, chip
removal, oil removal, comprehensive stepped-down filtration, precision cleaning
with ultrasonics, rinsing, and final rust prevention coating. A variety of sizes and configurations
had to be
accommodated using a universal work carrier. The process sequenced a line
consisting of PreWash, Ultrasonics Wash, Final Wash, Hot Water Rinse, and Final
RP Rinse Stations. All stages are constructed of heavy gauge type 304 stainless
steel and designed for 1000 pound loads.
 The PreWash and Precision Wash
stages (shown above) are gas heated using blast burners and rear wall mounted
serpentine heating coils. Both stages include high volume turbo systems. The
PreWash provides over 200 GPM and incorporates a powerful turbo filter system
with strategically located turbo jets, an inline chip removal system using
welded piping with a pull-out basket, dual filtration with pressure differential
monitor, and remote oil removal system. The Precision Wash also provides high
GPM and incorporates a powerful turbo filter system with strategically located
turbo jets, a very powerful ultrasonic cleaning system sequenced with Multiple
Rollovers, and dual filtration with pressure differential monitor.
Ultrasonics
The unique RAMCO ultrasonic
cleaning system cascades powerful sweep frequency (between 38 to 42 kHz)
ultrasonics with agitation/turbo/flushing/washing. Using mechanical
agitation washing to remove gross contamination and ultrasonic cleaning to
remove finer and/or more resistive deposits is a very effective processing
routine. The steps are sequenced with digital timers
for agitation/turbo/flushing/washing before after the ultrasonic phase. And
using our MultipleRollover feature the dual mode process can be repeated
for any number of preset “rollovers”. The results are faster cleaning
and more effective overall processing.
Final Wash and Rinse Stages
The PreWash and Rinse stages
(shown below) are electrically heated using high efficiency immersion heaters.
All stages include high volume turbo systems. The Final Wash incorporates turbo
filter with strategically located turbo jets and filtration with pressure
differential monitor. The Rinse Stage iincorporates turbo filter with
strategically located turbo jets and filtration with pressure differential
monitor. The Final RP Rinse Stage incorporates turbo filter with strategically
located turbo jets and filtration with pressure differential monitor. All stages
use RAMCO agitating platform oscillation to create
Dynamic Flow Combinations.
Other features include elevator platforms,
platform conveyors, and a universal work carrier (not shown) all
specifically engineered to maximize the effectiveness of agitation, solution
turbulation, and ultrasonic energy to the working zone. |
