Choose water-based automatic fire extinguishing device for fire prevention and extinguishing system of wide-body dump truck
The wide-body dump truck fire prevention and extinguishing system is suitable for coal mine automatic fire extinguishing systems/body dump truck automatic fire extinguishing systems/devices. It is used to collect mining and coal mining vehicle fire conditions in severe conditions and to collect mining and coal mining vehicle fire signals. Analyze signals. Alarm processing and fire extinguishing. Control, drug output and other operations.
Fire extinguishing features of water-based automatic fire extinguishing device for wide-body dump trucks:
1. Automatic fire identification without manual participation.
2. Exquisite appearance. Good sealing performance. Reliable function. Easy maintenance.
3. The dual design of agent pipeline and special atomizing nozzle can avoid the waste of fire extinguishing agent and improve the utilization rate of fire extinguishing agent, thereby achieving good fire extinguishing effect.
4. It can be equipped with automatic, manual and emergency start modes, making the operation convenient and flexible.
5. Support the self-diagnosis function of equipment faults and reduce manual detection costs.
According to different starting methods, automatic fire extinguishing devices/systems for wide-body dump trucks can be divided into mechanical manual fire extinguishing devices for coal mining vehicles and electric automatic fire extinguishing devices for coal mining vehicles, which can meet the needs of users without electricity and voltage, and achieve full automation, remote monitoring and operation. The fire extinguishing function and the design are more diverse and selective, thereby realizing customized production of special vehicles.
At present, due to its good fire-extinguishing performance and applicability in complex and harsh environments, this fire-extinguishing device has been widely used. Monorail crane locomotives, rock drilling platform locomotives, hydraulic excavators, shotcrete trucks, scrapers, open-pit coal mines and non- Coal mining vehicle field, such as explosives trucks.
Working principle of water-based automatic fire extinguishing device for wide-body dump trucks:
1. The temperature detector in the device can automatically sense the temperature in the mining vehicle protection zone. When the temperature in the protected area reaches the set induction temperature, the fire extinguishing device can sense and automatically start the control system and drive system, causing the medicine bottle group to be linked.
2. When the control system issues an alarm command, it controls the drive system, opens the control valve body in the medicine bottle, instantly releases the pressure in the medicine bottle, and pushes the water-based, ultra-fine dry powder, and perfluorohexanone fire extinguishing agent in the medicine bottle through the chemical pipeline from the dedicated The nozzle sprays continuously.
3. Specially customized nozzles can homogenize the fire extinguishing agent and release it quickly to form a fully submerged fire extinguishing zone.
4. Continuously spray fire extinguishing agent to extinguish the fire source to prevent secondary re-ignition.
The research and application of this fire extinguishing device is to provide fully automatic fire extinguishing mode for mining vehicles such as mining trucks, rock drilling rigs, wide-body dump trucks, loaders, underground scrapers, etc., to achieve the integration of detection, alarm and fire extinguishing, changing the traditional The old model of vehicle firefighting has taken a new step towards smart mine firefighting.
