(2). Air Pressure Regulator/Solenoid Assembly
The supplied air pressure regulator is permanently set at 65 psig, the optimal
setting for most adhesives.
The solenoid valve turns on after the sensor indicates level state and the time
delay has been reached. The solenoid directs compressed air to flow to the
suction lance.
(3). Suction Lance
The suction lance draws adhesive from the adhesive storage bin. The
suction lance includes:
S A venturi pump to draw in and transport the adhesive.
S A vibrator to keep the adhesive in loose condition. The vibrator is active
as long as compressed air is supplied to the suction lance.
Air line tubing and the adhesive transfer hose are connected to the suction
lance. The lance is placed in the PVC pipe located in the adhesive storage
bin.
(4). Adhesive Transfer Hose
The adhesive transfer hose connects the suction lance to the lid assembly.
The transfer hose conveys adhesive from the adhesive storage bin to the
melter tank.
(5). Lid Assembly
The lid assembly includes the filter stack, lid, fill tube, baffle and deflector:
S The filter stack contains a replaceable filter sock to prevent adhesive
fines and talc/powder in the adhesive from being emitted into the ambient
air.
S The fill tube attaches to the adhesive transfer hose.
S The baffle prevents adhesive from entering the filter sock.
S The deflector distributes adhesive evenly in the tank.
A safety interlock switch detects whether the melter tank lid is in place. If the
tank lid is not in place, the fill system will not operate.
