干粉灭火系统

ZFP型自动干粉灭火系统由启动装置(如:启动气瓶+拉杆机构)、氮气瓶组、减压阀、干粉罐、干粉枪、干粉炮、干粉喷头、电控柜、阀门和管系等零部件组成。一般为火灾自动探测系统与干粉灭火系统联动。

ZFP series DCP consists of starting device (Eg.:start cylinder + pull-rod mechanism), N2 cylinders, pressure reducing valve, powder tank, powder gun, automatic powder monitor, fixed powder nozzel, controller, valves, pipe lines and other accessories. In common use, ZFP series DCP is applied in using link with the fire-detecting system.

干粉罐是中压容器，由罐体、安全阀、人孔(装粉口)、进气口及出粉口等组成。

Powder Tank is a Middle-pressure vessel, consists of vessel, safety valve, manhole (powder intake hole), Nitrogen intake hole and powder discharge etc.

干粉炮是由耐压铜材和不锈钢制成，根据要求自动干粉炮(电动或液动)可在仰角40°俯角60°回转270°范围内工作;手动干粉炮可在仰角70°俯角60°回转360°范围内工作。

Powder monitor is fabricated by copper alloy and stainless steel, according to relative specification, the electric or hydraulic operated monitor can rotate between 40° to -60° in vertical direction, 270° in horizontal direction; the manual operated monitor can rotate between 70° to -60° in vertical direction, 360° in horizontal direction;

干粉枪与卷盘连在一起，卷盘中的软管长度可达30-40 m。

Powder gun is installed together with hose reel, the powder transport hose can have a max length: 30-40 m.

如果设备仅要求手动操作，则采用手动干粉炮、手动阀门和手动控制启动气瓶组件。

If only manual operation is needed, adopt a combination of manual dry chemical powder, manual valve and manual start cylinder.

系统工作原理是:利用氮气瓶组内的高压氮气经减压阀减压后，使氮气进入干粉罐，其中一部分被送到罐的底部，起到松散干粉灭火剂的作用。随着罐内压力的升高，使部分干粉灭火剂随氮气进入出粉管被送到干粉炮，干粉枪或干粉固定喷嘴的出口阀门处，当干粉炮、枪或干粉固定喷嘴的出口阀门处的压力到达一定值后(干粉罐上的压力表值达1.5~1.6MPa时)，打开阀门(或者定压爆破膜片自动爆破)，将压力能迅速转化为速度能，这样高速的气粉流便从干粉炮(或干粉枪，固定喷嘴)的喷嘴中喷出，射向火源，切割火焰，破坏燃烧链，起到迅速扑灭或抑制火灾的作用。

The principle of work for DCP system: Releasing the high pressured Nitrogen from Nitrogen Cylinder to Reduction Valve and decompresses the pressure to the work pressure, then transport them into Powder Tank, amount of them are transported to the bottom of the tank to relax the powder. Along with the tank's contenting pressure update, some powders are transfer to the discharge pipe and arrive at the valve bellowing the powder monitor / powder gun or powder nozzle along with the pressured Nitrogen, when the pressure in the valve arrives at the rated pressure (or the pressure gauge on the tank indicate 1.5~1.6MPa), open the valve (or the breakable diaphragm breaking auto.), then the pressure energy are translated to speed energy, high speed powder spray out from monitor (gun or nozzle ), shot at the fire, incise the flame, destroy the burning chain, then stifle the fire quickly.

ZFP型系列自动干粉灭火系统是石油化工、油船、油库、加油站、港口码头、机场、机库等工程的灭火系统的重要装备。干粉灭火系统是以氮气为动力，向干粉罐内提供压力，推动干粉罐内的干粉灭火剂，通过管路输送到干粉炮，干粉枪或固定喷嘴喷出，以达到扑救易燃、可燃液体，可燃气体和电气设备火灾的目的。

ZFP series Automatic Dry Chemical Powder Extinguish System (Short as: DCP) are important equipments for the fire-fighting in petrochemical industry, oil tanker, oil storage, gas station, dock and harbor, airport and hangar etc. ZFP series DCP is driven by high-pressure N2, then establishes pressure in the powder tank, press the chemical powder and force it through the pipelines to the powder monitor, powder gun or fixed powder nozzle, and by these equipments, spray the powder out on the flammable liquid, flammable gas or electric equipment fire to extinguish the fire.

ZFP型自动干粉灭火系统对A、B、C、D四类火灾都可使用，大量的还是用于B、C类火灾(应根据保护对象选用相应的干粉灭火剂)。其主要特点如下:灭火时间短、灭火效率高、对石油产品的灭火效果尤为显著;绝缘性好，可扑救带电设备的火灾，灭火后对设备污损较小;寒冷地区不需防冻，且可用于缺水地区;干粉灭火剂久贮不变质。

ZFP series DCP system can be used in A, B, C, D four kinds fire, the most common use is in B & C kind fire (according to different kind of fire choose the different type dry chemical powder for protection). Main futures bellowing: Short time for extinguishing, high extinguishing effective, outstanding effective on petrol product fire, best insulation, good effective on electric equipment fire, low pollution after extinguish, needless for frozen protect in cold weather, also can be used in water-lack area, best seal and storage for powder.

超细干粉灭火系统。以驱动方式分类为:贮气瓶型超细干粉灭火系统(型号为:ZFP100AC、ZFP300AC、ZFP400AC、ZFP500AC、ZFP750AC、ZFP1000AC、ZFP1500AC)、贮压型超细干粉灭火系统(ZFY25AC、ZFY50AC、ZFY200AC、ZFY100AC、ZFY50AC(II)、ZFY5AC(II)、充装的灭火剂类别又可分为:ABC超细干粉灭火系统、D类超细干粉灭火系统，以固定方式分类为:固定式超细干粉灭火系统、半固定式超细干粉灭火系统(如柜式超细干粉灭火装置)。

超细干粉灭火系统是由超细干粉供应源通过输送管道连接到固定的喷嘴上，再通过喷嘴喷放超细干粉灭火的系统。广泛用于生产车间、大型仓库、车库、机场飞机库等场所高效扑救A、B、C、D、E类火灾。
