Vibratory Sieve Repair
1. Open the feed hopper lid. Reach inside the hopper and disconnect the
sieve ground wire.
2. Remove the bolts and washers from the hopper cover.
3. Lift the cover (with the accumulator and sieve attached) off the hopper.
Block up the cover to prevent damage to the screen assembly on the
underside.
4. Unfasten the two toggle clamps and remove the screen basket. Discard
any scrap powder and vacuum out the basket. If the basket is
damaged, replace it. If no further disassembly of the sieve is necessary,
reattach the basket and disregard steps 5 through 7.
5. To remove the air motor, disconnect the two air lines. Remove the bolt
and spacer.
6. Remove the accumulator from the sieve and disassemble the rest of the
sieve. Note the position of the screws, washers, nuts, rubber grommets
or washers, and gaskets.
7. Clean powder residue from the accumulator and sieve parts.
8. Assemble the sieve and install it on the hopper. Cap any unused
accumulator inlet tubes.
Pulse Valve Replacement
The pulse valves connect directly to the air manifold. To avoid connecting
the valves to the wrong solenoids, remove and replace one valve at a time.
Incorrect connections will cause the valves to open in the wrong order.
WARNING:
Before performing the following procedure, shut off the system
compressed-air supply and relieve the system air pressure. Shut off
electrical power at the system electrical panel. Lock and tag the disconnect
switch.
1. Remove the color module from under the base as described in the
Reclaim-to-Reclaim Color Change procedure in the Operation section.
2. See Figure 7-5. Disconnect the pilot air tubing (6) from the pulse-valve
tube fitting (5).
3. Unscrew the pulse valve (7) from the manifold nipple.
4. Remove the tube fitting and nozzle (8) from the old valve. Wrap PTFE
tape around the threads of the tube fitting and nozzle. Install the fitting
and nozzle into the new valve.
