Fire extinguishing function of water-based automatic fire protection and extinguishing device in engine room of rock drilling rig
The water-based automatic fire prevention and extinguishing device in the engine room of the rock drilling rig uses water as the flame retardant. It coordinates and controls the fire detection system, starting device, sound and light alarm device, fire extinguishing agent transmission system and injection system through the central controller. It integrates fire detection, It integrates alarming and fire extinguishing. In large industrial and mining enterprises, it can protect engine rooms, battery boxes, wire boxes, hydraulics, and oil pipelines from fire.
Rock drilling rig is a kind of rock drilling equipment used in tunnel and underground engineering construction using drill and blast method. It can be divided into tunnel drilling rigs, mining drilling rigs, anchor drilling rigs and surface drilling rigs. Under high temperature, high humidity and harsh environments, the corrosion on vehicles is more than ten times that of ground working vehicles. Rock drilling rigs generally use high-voltage power supply and low-voltage control. If a circuit malfunctions, it will become unbalanced. The heating of electrical components indirectly affects the hydraulic oil temperature. If the pulse generator is damaged, the lubricating oil will not work, and the rock drill will wear out, causing oil leakage and heating, which can easily cause a fire. Regarding the cost of rock drilling rigs, once a fire occurs, the losses will be very serious.
Rock drilling rigs are mainly used for tunnel excavation and underground mining. There are high fire safety hazards. The water-based automatic fire prevention and extinguishing device in the engine room of the rock drilling rig is small in size, flexible in application, and has high earthquake resistance. Pipes and lines are mostly made of stainless steel and copper, with an anti-corrosion layer on the surface. They are protected by flame-retardant, wear-resistant, shock-absorbing and anti-corrosion protective sleeves. They can also work normally in a mine environment with moisture, high temperature and flammable gas, ensuring that the vehicle and equipment safety.
Based on the characteristics of the water-based automatic fire prevention and extinguishing device in the engine room of the rock drilling rig, let me introduce it to you:
1: The fire extinguishing agent used in the water-based automatic fire extinguishing device in the engine room of the rock drilling rig is mainly composed of hydrocarbon surfactants, fluorocarbon surfactants and flame retardants.
2: After water-based spraying, it will adhere to the surface of the object to form a water film. The nano-molecule components contained in it can penetrate into combustible materials and effectively block the source of fire.
3: The agent can form a water film on the surface for a long time. Even if the water film is damaged, its unique cycle can heal quickly and suffocate the flame.
4: Colorless, non-toxic, low corrosivity, will not cause secondary damage to personnel and equipment, has high fire extinguishing efficiency and low re-ignition property.
