SPCL36104-S Suction System
4.0
OPTIONAL COMPONENT FUNCTIONS
Additional options may be supplied with the system. The following are available at time of
manufacture.
4.1
POWERED PART HOLD DOWN ROLLERS
Pneumatic powered rollers hold the part down against the mandrel. The rollers come down on
each end of the part to secure it during a blast cycle. One set of these rollers moves
horizontally to accommodate the length of the part to be blasted This is accomplished thru the
PLC .
4.2
NOZZLE OSCILLATOR
The Nozzle Oscillator drive is mounted on the back wall of the Blast Cabinet. An oscillating
bar extends into the Blast Cabinet to support the Blast Guns. The Oscillator moves
horizontally over the surface of the part. Home (park) position may be extended or retracted
and is determined at time of manufacture.
4.2.1 (N/A) Pneumatic Cylinder Driven Oscillator
This Oscillator provides an inexpensive means of increasing blast coverage.
Oscillation speed is adjustable with flow control valves at each of the cylinder’s two
(2) ports. Limit switches control the cylinder stroke length. The duration of the blast
is controlled by a Blast Timer or a Blast Counter.
4.2.2 D.C. Motor Driven Timing Belt Oscillator
The D.C. driven Oscillator permits improved control of oscillation speed and distance.
This is required when precise blast specifications must be met. A DC Motor Control
Board controls the Oscillator Speed. Stroke length is controlled with the PLC.
4.2.3 D.C. Motor Oscillator with PLC Control
When incorporated with a PLC, the processor may be programmed to control the
Oscillator movement including Park Position, Blast Length and Blast Strokes/Time.
A DC Motor Control Board controls Oscillator Speed.
4.3
(N/A) AUTOMATIC MEDIA REPLENISHING SYSTEM
This system includes a 4 cubic foot capacity Makeup Hopper, an automatic Sure-Flo
®
Grit
Valve and a Makeup Hopper Low Level Sensor. The Sure-Flo
®
Grit Valve at the bottom of
the Makeup Hopper will open and add media to the system if the media level in the Storage
Hopper is not at the proper level. The Makeup Hopper Low Level Sensor and a panel
mounted indicating light which will illuminate when the Makeup Hopper must have media
added.
This option is particularly useful when media must remain consistent. As media breaks down
and is drawn to the Dust Collector, fresh media of the proper size will mix with the reclaimed
media ensuring a consistent mix and repeatable finish.
