Filling stations Powder fire extinguishers

摘要

The invention relates to fire fighting equipment, and more particularly, to stationary equipment with a reservoir for supplying powder extinguishants, in particular for filling of fire extinguishers using pre-dilution. filling station powder in the extinguisher comprises a cyclone associated conduit equipped with a filter, with a vacuum pump fixed to the bottom cone of the cyclone a charging device comprising a cover with a seal of the neck of filled fire extinguisher mounted on the support table, and a central tube disposed in a nozzle discharge excess air, coaxially mounted in the cyclone which feed nozzle suction tube of the refueling tank, a flexible hose connected through a valve and filter crusher. What is new is the fact that as a reference table refillable extinguisher used electronic scales, is electrically connected with the actuator valve suction tube and the cyclone is hung on the beam, the balanced counterweight, the cyclone filter is arranged in the form of a water trap mounted on a perforated end discharging excess pipe air in a vessel void volume which is interposed between the check valves. The proposed technical solution provided accurate automatic powder dosing volume productively filled to the extinguisher, when the current control of its mass, increasing the efficiency of cleaning exhaust air with recycling of excess working fluid in the form of an aqueous solution.
