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, dynamic unit, balance
valve, foam proportioner, control valves and control system.
Principle
When a fire happens, water pump and foam pump will be start ed. The pressure of water and
foam solution will be feed back to balance valve, so balance valve will adjust its opening
degree to reach dynamic equilibrium. Foam solution and pressuri zed water will mix in foam
proportioner to form foam solution. If the pressure and flow from water inlet are unstable,
balance valve will adjust the amou nt of foam concentrate to reach dynamic equilibrium to
guarantee an accurate mixing ratio. Atmospheric foa m tank can be feed even when the unit is
under operating, which prolongs the working time.
Category
The unit can be divided into motor drive, water turbine drive, diesel drive or the combination of
two of the dynamic according to the dynamic source of foam pump.
Water Turbine Drive
The water turbine drive foam pump proportioning system rely on a water turbine to drive the
foam pump. While, the water turbine is driven by pressurized water. So there is no other
dynamic needed as long as pressuri zed water
Motor Dirve
Motor drive foam pump proportioning system drives foam pump with a motor. There are two
motors available that if one of them was broken, the spared one will switch to work to
guarantee the system can operate normally.
