【 Weak current College 】 fire water systems maintenance management

Fire water system mainly by the fire hydrant system and automatic sprinkler fire-fighting water supply system made up of two parts.
Because of the usual maintenance, neglect of management, often makes fire water system does not maintain a good working condition, a key moment to play a role. Therefore, strengthening the fire water systems maintenance management has become a major topic in front of people.
Fire hydrant maintenance management system
Fire hydrant system generally include municipal fire hydrant system and architecture within the fire hydrant system. Its maintenance management should do the following:
Raising the awareness of citizens and legal concepts of fire, no damage, occupy, bury fire hydrant. This is the most fundamental one. The FSO People's Republic of China shall clearly states: "all units and individuals are responsible for protecting fire facilities ... To bury and occupy the fire water ... ".
Strengthen the fire hydrants and fire water pipe of inspection and maintenance, the timely removal of debris around the hydrant, fire hydrants with no rust check leakage phenomenon, for fire protection design of rubber gaskets and seals for damage or loss, whether of gate opening hydrant flexibility, time the necessity should stem and lubricating oil. In addition, on indoor hydrant you should also check the box of water gun fire hydrant, hoses, etc. equipment complete, there is no mold rot hose, problems, correct.
Do a fire hydrant winter protection to prevent the fire hydrant water froze and blocked pipeline. Especially the Northern cold areas, winter before shall take the necessary measures of antifreeze.
Maintain the integrity of the hydrant logo stand out. On the parking lot around the hydrant, should draw up a range of establishment signs, prevent drivers will be parked at the fire hydrant and impact, on the underground fire hydrant, covers a more proper landmarks, to distinguish them from underground pump adapter, avoid fire out of the chaos in the busy.
Sampling of water hydrant at any time. On the important parts of a fire hydrant should individually in each outlet check; on non-key parts of the fire hydrant can be 10% of the total number of hydrants ~ 20% for effluent sampling experiment.
Indoor hydrant system should also be readily observed fire water tank, water tank, the water level should complement the shortcomings. Usually need to strengthen the pump motor maintenance and regular checks of fire pump bottom valve and the outlet pipe valve and the valve is in normal state. Each fire pump shall every 1 to 2 weeks to carry out a running test, ensure that the water properly.
Automatic sprinkler fire water systems maintenance management
Automatic sprinkler fire-fighting water supply system as the building of one of the fixed fire extinguishing facilities, must be full of water, fire and periodical checking system maturity level, so as to achieve a perfectly safe. For automatic sprinkler fire-fighting water supply system of maintenance, should do the following:
Do a nozzle maintenance management. Should store the appropriate number of nozzle for replacement. Fire sprinkler system startup time, regardless of the automatic opening of nozzle or unqualified sprinkler, fire suppression and should be replaced after the corresponding type of sprinkler head. At the same time, the warehouse should have kept the number of spare sprinkler heads shall not be less than the total number of installed nozzle, 1% of all types and different temperature scale number of nozzle shall not be less than 10 but not more than 50. To strengthen maintenance management, prevent nozzle rust. When installed in steam, nozzles chemistry corrosive gases and moisture concentration of large environments or nozzle and dissimilar metal contact, nozzle will soon be corroded, at this point in time will replace corroded nozzle. Should prevent dust accumulation in the nozzle, affect the sensitivity of the sprinkler head movements. Check found sprinklers on the accumulation of dust application brush out or blown clean. To prevent water distribution pipe and nozzle clogging. As a result of water distribution in easy access to sand, debris and other debris, the pipeline passes water blocked, when these impurities in the Jet action, will flow into the nozzle and the nozzle clogging. Should prevent leaking pipes and nozzles. Cause water distribution pipe and nozzle leak was mainly attributable to the pipeline rupture, frozen pipes and nozzles from mechanical damage or nozzle overheated and so on. Therefore, in the high area, steam room, heating and prone to overheating of the place, to prevent accidental injection nozzles, paying special attention to the regular inspection and maintenance.
Periodically check the entire spray system to ensure system integrity. You should always observe: the adoption of protective measures for the part is all protection measures; the gate valve open and close the system state is consistent with the requirements, wet alarm valve, dry alarm valve, valve, preaction valve for pressure gauge pressure is displayed with the design requirements; fire water tank, water tanks of water level is reached, and to do so, each month on the fire pump to carry out a running test, running time normally not less than 5 minutes a week on the fire pump, air compressor, electric equipment of the fire.
In case of fire, automatic sprinkler systems to work long hours, and response system for parts and even conduct a comprehensive inspection of all system and the comprehensive functionality of the experiment.
Development of strict management system and system procedures, for the relevant staff, strengthen and part-time firefighters training, enhancing fire safety awareness, establish post responsibility system to ensure that 24 hours monitoring at any time someone on duty. At the same time, the clear responsibility to the people, the system checks and maintenance of the register for verification.
