A+H Water motor driven Proportioner consists of water motor, piston pump, shaft coupling, valves,piping as well as supporting frame, include standard version and seawater version. Standard version is used for fresh water, the material of water motor is high strength aluminium alloy, seawater version is used for sea water, the material of water motor is bronze. Water Motor It consists of casing、cover、housing、rotor、vane and mechanical seals etc. the unique structure design makes flow range wider and pressure loss smaller. Piston Pump ...
Thewater motor ① isdriven by the extinguishing water flow which passes through it, thewatermotor drives the piston pump②, this pump intakethe foam concentrateand injectitinto the waterpipework. Becausethe water motor① and the pistonpump② areof the positivedisplacement pump, the volume ofthe water motor① andthe pistonpump② is aconstant within a certain speed range. That is to say, theflow rate of water motor is linear proportion to its speed. Aslong as the displacementof water motor① andpiston pump match each other, the accurate proportioningratio canbe achieved. For...
Water Driven, No Power Requirement Proportioner is driven by water directly, no electrical or diesel engine requirement, but is different with pelton water turbine, no drain and don’t need special drain tunnel. As long as the main water pump running, proportioner will be run, then reliability of the foam system is increased. Positive Pressure Injection, No backpressure required. The piston pump pressurized foam solution so that the injection point pressure slightly higher than the water pressure, no any back pressure required within pressure range, suit...
