Automatic Fire Suppression System For Mining Equipment
Fire on surface mining equipment is a serious hazard to life and property. The large size of these equipments magnifies the problem by increasing the potential for fires, obstructing the operators’ view of fire hazard etc. With the increasing size of the equipment, the portable fire extinguishers are totally inadequate, to minimize this, we provide Auto Fire Detection and Suppression System for mining equipment.
Our Fire Suppression System proposed for installation on mining equipment would cover pre-determined hazardous areas in and around the engine, hydraulic & transmission systems etc.
It would be tailored to suit the operating conditions, wherein the equipment are used in Mines and other areas prone to high temperature / flames.
Automatic fire suppression system saves human lives & protects property/equiments from any kind of fire accident.
1) Detection of OVER HEAT / FIRE conditions.
2) Activation of a loud audio alarm.
3) Shutting off Engine / Power Supply automatically. (optional)
4) Activation of Extinguishing System.
a) Activation of Solenoid Valve on pressurised Pilot Cylinders leading to release of pressurised Nitrogen into DCP Cylinders.
b) Propulsion of DCP through the hose network from the nozzles to extinguish fire.
5) Built in Test Equipment.
6) Manual Override facility.
The detection of Overheat/Fire condition is based on thermal sensing. This is done by a sensor cable located around/near engine, pumps, fuel/hydraulic tank, valve bank etc., The sensor cable is a continuous heat detector, which can respond to fire on any part of its length. It is comprised of two steel conductors individually insulated and twisted together to impose a spring pressure between them, then wrapped with a protective tape and finished with an outer jacket suitable for the environment where it is installed.
The sensor cable is a fixed temperature digital sensor and is capable of initiating an alarm once its rated activation temperature (180 C) is reached. At this temperature the heat sensitive polymer insulation melts and yields to the pressure upon it permitting the inner conductor to move into contact with each other and initiating signal to the control unit and the extinguisher system.
