SAFETY COMPONENT CALIBRATIONS
The components listed below are adjusted at the indicated pressure values
–
safety valve: 12 bar (factory sealed - do not modify)
–
safety pressure switch: 11 bar (factory sealed - do not modify)
–
pressure transducer: 10 bar (adjust during installation, if necessary).
COMPONENTS
The steam generating systems
ECOVAPOR
feature a series of components that can be divided into:
–
Safety components (safety valves, safety level switches, safety pressure switch).
–
Indicators (level indicator, manometer, flame light).
–
Adjustment components (level adjusters, pressure switches, pressure transducers).
–
Feed components (centrifugal pump).
–
Operation components (shut-off valves, drain valve).
Hereinafter are the descriptions of the operation of each single component.
PRESSURE GAUGE
The manometer indicates the reached steam pressure value. The value of the design pressure is shown in red on the graduated
scale.
The manometer is fitted onto a three-way valve allowing to carry out the following operations:
–
Communication between generator and pressure gauge (normal operating position).
–
Communication between pressure gauge and the outside (position needed to purge the siphon).
–
Communication between generator, pressure gauge and sample pressure gauge (position needed for pressure gauge
comparison).
