Isuzu ELF rescue fire fighting truck

Procedure:

The working principle of the ISUZU NKR fire truck with nitrogen gas mainly includes the following steps:

1. Start the control system: First, start the control system to put the nitrogen fire truck into standby mode. The control system usually includes electronic components such as LCD screens and programmable logic controllers to realize operations such as fire extinguishing start, nozzle scanning and pipeline protection.

2. High-pressure nitrogen supply: High-pressure nitrogen is stored in nitrogen storage tanks, and the pressure is reduced and the flow is adjusted by the pressure regulation system and the flow regulation system to meet the specific fire extinguishing needs. The pressure regulation system consists of a pressure gauge and a pressure reducing valve to ensure that the nitrogen is released at an appropriate pressure.

3. Nitrogen injection fire extinguishing: When a fire occurs, the control system automatically starts the nozzle system to spray high-pressure nitrogen into the fire area. The rapid injection of nitrogen can reduce the temperature and oxygen concentration at the fire scene, thereby achieving the purpose of fire extinguishing. Since nitrogen is non-flammable, not easy to conduct electricity, and will not damage equipment and objects, it is very suitable for use as a fire extinguishing agent.

4. Completion of the fire extinguishing task: After completing the fire fighting task, the control system automatically shuts down the nozzle system, and the nitrogen fire truck enters standby mode.

Technical features:

1. Nitrogen storage system: The Isuzu mini fire nitrogen gas truck is equipped with a large-capacity high-pressure nitrogen storage tank. Nitrogen is usually stored in liquid form to increase storage density.

2. Nitrogen release mechanism: The NKR fire truck is equipped with a sophisticated control valve system, which can adjust the amount and speed of nitrogen release according to the fire situation.

3. Fire extinguishing principle: Nitrogen is an inert gas that is non-flammable and non-combustible. By quickly releasing a large amount of nitrogen, the oxygen content in the air is diluted. When the oxygen concentration in the environment drops below about 15%, most substances cannot continue to burn.

4. Cooling effect: The Isuzu fire truck with nitrogen gas bottle, liquid nitrogen quickly vaporizes during the release process and absorbs a lot of heat. This process can significantly reduce the temperature of the fire scene and assist in fire extinguishing.

5. Penetration: Nitrogen has good penetration and can penetrate into small spaces. It is suitable for confined spaces or inaccessible fire sources. It is particularly suitable for dealing with flammable liquids and gas fires, suitable for electrical fires, and will not cause secondary damage. It is effective in confined spaces such as basements and tunnels.

6. Control system: The Isuzu NKR fire water truck is equipped with an advanced electronic control system that can accurately control the amount, speed and direction of nitrogen release. It is usually equipped with a thermal imaging camera to help locate the fire source.
