Fire Fighting Balanced Pressure Proportioning System Foam Skid
Fire Fighting Balanced Pressure Proportioning System Foam Skid
Introduction
The foam pump proportioning system is the unit to supply foam solution for foam system. It is especially applicable to petrochemical enterprises, oil depots, wharfs and drilling platforms. The system mainly consists of atmospheric foam tank, foam pump, power unit, balance valve, foam proportioner, control valves and control system.
Principle
When a fire happens, fire water pump be started. Pressure and flow of fire water will be feed back to balance valve. Foam and water will be mixed in foam proportioner to get foam solution. If the pressure and flow from fire water changed, balance valve will adjust its opening degree to adjust the flow of foam, reaching a dynamic equilibrium to guarantee an accurate mixing ratio. Atmospheric foam tank can be refilled even when the system is under operating, which prolongs the working time.
Hydraulic Turbine Drive Foam Pump Proportioning System
The hydraulic turbine drive foam pump proportioning system relies on a hydraulic turbine to drive the foam pump. Hydraulic turbine generates a rotation by pressurized water to drive the foam pump, no other extra power is needed.

INSTALLATION
1. Build a foundation for both the skid and foam tank. The two foundations should be in an equivalent elevation.
2. Mount the skid and foam tank on their respective foundations with anchor bolts.
3. Connect foam tank foam outlet with skid foam inlet by flexible pipe.
4. Full Fill foam tank with foam concentrate from foam reflux inlet, then connect foam tank foam reflux inlet with skid foam reflux pipe by stainless steel pipe.
OPERATION
1. Keep wash valve closed and open all other manual valves
2. Start fire water pump to supply pressurized water for this system.
3. Press the "foam inlet valve open" button (green color) on control box to allow foam get into the system.
4. Press the "hydraulic turbine valve open" button (green color) on control box to start the hydraulic turbine. System will be under operating by now.
5. Press the "foam inlet valve close" button (red color) to stop the foam getting into the system.
6. Open the manual wash valve to allow water get into the system. Keep the fire pump running for several minutes to wash the system with fresh water.
7. Press the "hydraulic turbine valve close" button (red color) to stop the hydraulic turbine.
8. Stop fire water pump to stop water supply.
9. Close all manual valves on the skid to set it into standby condition.
