Industrial Combustible and Toxic Gas Detector Daily Maintenance and Precautions
Combustible and toxic gas detector can detect flammable and explosive toxic and hazardous gases are: acetylene, methane, ethane, propane, methanol, ethanol, propanol, ethylene, toluene, xylene, acetone, vinyl chloride, liquefied petroleum gas, natural gas, methane, solvent oil, ethylene oxide and other flammable gases, these flammable gases are flammable and explosive, extremely dangerous, therefore, if there are any of these flammable gases in the industry, it is recommended to Therefore, if these flammable gases exist in the industry, it is recommended to install flammable and toxic gas detectors, flammable gas detection sensors and other detection and alarm instruments.

Principle of Fine Mist Fire Extinguishing System
In the quasi-working condition, the water mist system from the pump group outlet to the area valve in front of the pipe network (closed from the pump group outlet to the nozzle of the pipe network) to maintain the pressure, when the pressure is lower than the pressure regulator pump is set to start the pressure of 8 bar, the pressure regulator pump to start, so that the system to maintain a stable pressure network (8-14) bar, the pressure regulator pump running for more than 10 seconds after the pressure is still less than 14 bar, the fine water mist fire extinguishing system work! Principle, the main pump starts, the pressure regulator pump stops.
System components and working principle of closed fire extinguishing system
Closed high pressure water mist fire extinguishing system including full flooding application mode and local application mode, is the use of closed water mist nozzle, by supporting the automatic fire alarm system automatic chain or remote control, manual start, control a group of nozzles at the same time spraying water automatic water mist fire extinguishing system.
System components and working principle of open fire extinguishing system
Open high-pressure water mist fire extinguishing system, including full flooding application mode and local application mode, is the use of open-type water mist nozzle, by the supporting automatic fire alarm system automatically chained or remote control, manual start, control a group of nozzles at the same time spraying the automatic water mist fire extinguishing system.

Open fine water mist fire extinguishing system set up the necessity of pressure stabilizing pump system
Norms require closed water spray system pump group should be set up pressure stabilizing pump, but not open water spray fire extinguishing system to put forward clear requirements, in fact, open water spray fire extinguishing system should be set up pressure stabilizing pump, specific reasons are as follows:

Principle and application of water spray fire extinguishing system
Water spray fire extinguishing system refers to the water source, water supply equipment, piping, rainfall valves, filters and water spray nozzles and other components of the system, the fire extinguishing mechanism is when the water in a fine mist of water droplets sprayed onto the surface of the burning material, resulting in a combination of surface cooling, asphyxiation, emulsification and dilution effect, to achieve the extinguishment of the fire, water spray fire extinguishing system is commonly used to fight solid fires and flammable liquid fires with flashpoints higher than 60C.
