2016 a-php security fire fight equipment balanced pressure equipment in Weite fire fighting
Summary
PHP series balanced pressure proportioning device is usually used in area which require larger foam mixture Its main principle is that, use balance valve to control the mixing ratio of foam liquid. Firstly, foam liquid are pressed into the balance valve by the foam liquid pump, then adjusted by the balance valve into proportioner. When the water pressure and flow of fire main line change, the balancing valve can dynamically adjust foam fluid injection of proportioner, to ensure that during the device operation, the foam liquid come constantly into proportioner, get more accurate mixing ratio, and foam fire extinguishing equipment can jet qualified foam, so that firefighting is effective.Compared with pressure foam proportioning mixing device, the traditional balance type proportion mixing device is provided with the big foam liquid reserves, added foam agent at any time, the higher reliable, and more accurate mixing ratio
Structure
Balanced pressure proportioning device mainly consist of dynamic configuration the motor (diesel engine), foam liquid pump, balance valve, safety valve, proportional mixer, foam liquid pump, electric control cabinet, atmospheric foam tank, a public base and pipeline accessories, etc..According to the different dynamic configuration, balanced pressure proportioning mixing device can be divided into double motor driventype, one motor and one diesel engine driven type, double water turbine driven type and one turbine and one motor driven type.
Applications
Balanced pressure proportioning device is suitable for petro chemical enterprise, large oil depot, oil jetty, oil port, oil field, tank farm and oil refinery and other places.
