4. OPERATING PRINCIPLE
The 2 BASE and CATALYST materials are sent to the mixing machine from 2 pumps or pressure tanks.
The base crosses a piloted valve (A1) and a meter (CA), the catalyst is directly sent to the meter (CB). The
cycle begins with the opening of the BASE valve (A1). The 2 meters send their informations to the
computer that shuts off the catalyst valve (VP6) when the computerized mixing ratio is reached.
The mixing process is based on a base constant flow. The catalyst flow is injected low under high
frequency. The injection is made directly into the base flux at the mixer level.
The automaton checks continuously the mixing ratio and if it notices a fault that it cannot correct, an alarm
is activated. The machine goes on safety mode.
