Isuzu fire fighting truck

Dry powder system Isuzu fire truck refers to a system that connects a dry powder fire extinguishing agent to a dry powder cannon, through a dry powder storage tank and nitogen bottles, also the matched delivery pipeline and English control panel. When the fire occurs, the system is automatically or manually started to spray the dry powder fire extinguishing agent from the top cannon to extinguish the fire. Isuzu fire truck Dry powder fire extinguishing agent is usually made of fine particles made by mixing and grinding a fire extinguishing base material, such as baking soda, ammonium carbonate, ammonium salt of phosphate, etc. With an appropriate amount of lubricant and a small amount of moisture-proof agent. It is a dry and easy-to-disperse solid powder fire extinguishing agent used for fire extinguishing.

Dry powder Isuzu fire trucks are one of the widely used fire extinguishing equipment in the fire fighting field. Its dry powder system has the characteristics of fast fire extinguishing speed, non-conductive, and non-strict requirements on environmental conditions. Isuzu dry powder fire engine can quickly and effectively extinguish various types of fires. When using it, you should follow the correct operating procedures and safety regulations to ensure its fire extinguishing efficiency and personnel safety. And below detailed from POWERSTAR showing working principle and operation guidance of ISUZU fire tenders:

Add Dry Powder into the tank
Open the filling hole, then you can fill in Dry Powder into the tank directly. Please note that it is strictly prohibited to filling any agglomerate powder into the tank to avoid stocking the pipeline. And make sure the dry powder is clean enough.

Add Nitrogen into the Two Bottles

The Nitrogen system is matched to be used with dry powder system, based on dry powder tanker capacity then matched with suitable capacity Nitrogen bottles. Suitablely operate the system based on the control system.

Dry Powder System Working Steps and Principle
1)    Press the Power Button, make sure the Dry Powder System is electric on.
2)    Turn off the Nitrogen Inlet Valve, turn on the one or two Bottle Valve and Nitrogen Outlet Valve, check the high pressure gauge is 13Mpa and low pressure gauge 1.4Mpa.
3)    When low pressure gauge showing pressure 1.4Mpa and keep steadily. Then can turn on the Tank Inlet Valve Button. Check the Tank Pressure Gauge, when it is 1.4Mpa and keep steadily, means the dry powder is ready for jetting. You can turn off the Tank Inlet Valve Button.
4)    Turn on the Powder Gun Outlet Button, use the pipeline and gun for firefighting process.
5)    After dry powder jetting working, turn off the Powder Gun Outlet Button, turn on the Pipeline and Gun Cleaning Button, which can use residual Nitrogen to cleaning the pipeline and guns. Turn off all valves and make it ready for next working.
 

Dry Powder System Working Notice
(1). Skilled Operator for management, the Operator must be familiar with all operation steps. And guarantee system working well.
(2). Nitrogen Tank pressure should be checked every month, adding or change Nitrogen when pressure less than 10Mpa. Make sure High-pressure Shutoff Valve is closed.
(3). Adding Dry Powder notice: before adding powder, carefully check tank pressure, if still have pressure, please exhaust Nitrogen firstly. Only when Nitrogen exhaust out then can open tank cover or powder adding valve. After adding finished, please check if there is leakage.
(4). Dry Powder Tank need to be checked every year. Also need to exam single-way valve at bottom of tank. Replace new one when have block or rusting.
(5). Nitrogen Tank, Dry Powder Tank, Safety Valve, Pressure Gauge all should be exam  and tested regularly.
(6). Carefully check the whole system every half month. low pressure area have pressure over 1.4Mpa and keep increasing, turn off High-pressure Shutoff Valve immediately. Turn on the Outlet Valve and maintenance Pressure Reducing Valve. Pressure Reducing Valve has been set before delivery, please donot adjust.

 
The Isuzu dry powder fire truck is mainly equipped with dry powder fire extinguishing agent tank and dry powder spray device. Use dry powder to extinguish flammable liquid fires, gas fires, electrical fires, as well as general material fires. For large-scale chemical plant pipeline fires, the fire fighting effect is particularly significant. It is a standing fire truck for petrochemical companies.
