The main configuration of the "Ariel" low pressure
foam machine consists of:
a)
FRAME
The frame has been conceived to make easier all the
standard and exceptional maintenance operations so reducing
the service times.
A basement of comfortable dimensions, but not bulk, permits
each part of machine to be approachable easily and rapidly.
The whole can be put on articulated supports or wheels according
to customer's need.
b) POLYOL-ISOCYANATE TANK MODULE
· Flanged carbon steel tank having 50/80 ltr capacity.
· Component flow ball valve at suction port.
· Visual level through transparent pipe fitted on 1/2"
unions; (option: floating load levels).
· Option: load pumps with diaphragm or servo-controlled
valves.
c) POLYOL-ISOCYANATE METERING MODULES
The two modules are placed at the bottom of framework, and
enough high to be maintained.
The main features are:
· volumetric high-accuracy gear-pump;
· 3phase asynchronous motor (8 poles , 700 rpm, servo-fanned)
to be coupled with inverter;
· lantern coupling;
· TUV certified pipes;
· safety pressure gauge, type DN 100 (½"
vertical connection, 0-20 bar).
· 0-40 digital pressure gauge with 3 figures and max
safety contact.
d) THERMOREGULATION MODULE
· Tube-nest heat exchanger.
· Heating element (1500W-400V power with cables l=2000).
· Temperature feeler, type PT 100, placed at the bottom
of component tank.
· Cooling water on/off ½" valve, type AN
133.
· System for temperature control and cycle process,
by means of a high-accuracy digital thermoregulator (+/- 1°C
tolerance).
· Option: component conditioning system (3000 frig/h).
e) SOLVENT WASHING MODULE
· 18 litres capacity stainless steel pressurised tank.
· Pressure gauge c/w manometer.
· Solvent on/off solenoid valve sited near the head.
· Main air on/off solenoid valve to dry the head.
· Option: water washing system by means of an independent
unit instead of solvent one.
f) MIXING HEAD MODULE
The mixing head is of Ekosystem make.
Its working concept lies in the continuous recycle of components
in head by means of flow-valves pneumatically controlled via
a solenoid valve sited near the head.
The mixer can be of two different typologies:
· standard with helical millings;
· "pin"-made to be used for processing high
viscosities or big outputs.
g) CONTROL AND PUSH-BUTTONS PANELS
All the necessary controls for machine operation are of easy
approach.
A Siemens operator board processes the working and head washing
times, and is also the interface used to visualise the machine
alarms, such as:
· pumps motors overload;
· mixer motor overload;
· polyol/isocyanate max pressure;
· polyol/isocyanate max level;
· solvent min level.
The
panel inside accommodates:
1 Siemens Simatic 57-200 plc for sequntial control of functions;
2 The inverters to handle the motors of metering groups.
The
push buttons panel sited near the mixing head and integrated
in the head-holder support is equipped with:
· 2figures display visualising the cycle number and
the time given to the same cycle before the pouring phase;
· button to increase the cycle just displayed;
· button to decrease the cycle just displayed;
· red mushroom button of emergency;
· pouring start button;
· pouring stop button;
· solvent washing start button;
· air blast start button.
The
push buttons panel is also provided with a handle so that
the end-user can operate and displace the head module along
the production line easily.
