DLC series product is applicable to work under the
following conditions:
1.Environmental temperature:5~40;
2.Relative air humidity:85%(when 20
5);
3.Medium temperature:4~70
;
4.Power supply voltage:380V (+5%-10%)
At work,the water supplementing pump transports water to the water pipe-net and the redundant water enters the pneumatic tank.When the water level gets to the set value SN3,the pressure stabilizing water pump stops and,at this time,the system pressure is not up to the set value,so the pr
essure stabilizing air compressor starts working and then stops when the said pressure gets to the upper limit of the stabilized pressure.When the pipe-net pressure is made lowered,due to the system leak etc.causes,to the lower limit of the stabilized pressure,the pressure stabilizing air com-pressor will restart working,if water is detected at the point of the set value SN2by the level detector,and,if no water is detected therein,then the water supplementing pump will restart working,continuously cycled in this way.When the fire-fighting apparatus is put into work in case of a fire,the pressure stabilizer can not maintain the pipe-net pressure.When the pressure is lowered to SP3or the fire-fighting signal is input,the air top-pressing device starts working to press the water inside of the pneumatic tank into the fire-fighting pipe-net and provide the pipe-net with 10min fire-fighting water and,when the level lowers to the set value SN1,the air-stopper is closed tom prevent the air inside of the pneumatic tank from going into the fire-fighting pipe-net.

6.DLC product holds advanced multi-functional programmed control and can receive various fire-fighting signals and can be networked with the fire-fighting center.
7.The air top-pressing device of DLC product is fitted with a dry battery as the standby power and is workable even with the external power cut off,leaving a safe and reliable fire-fighting and extinguishing performance.橡胶弹力球
8.The accessories of DLC product are adopted after selection from many manufacturers,so product quality is reliably guaranteed.The key parts of standard product,such as motor,water pump bearing,programmable controller,circuit breaker,contactor and relay etc.adopt international and domestic famous brand products.
9.DLC product can store 10mini water for fire fighting,which can replace indoor water tank used for fire fighting.It has such advantages as economic investment,short building period,convenient construction and installation and easy realization of automatic control.It is especially applicable for the construction of earthquake area construction,concealed project,provisional construction and construction where high level water tank is not appropriate to be set due to construction technology.

DLC air top-pressing fire-fighting water supply equipment belongs to the emergency fire-fighting water supply equipment and can meet with 10min fire extinguishing at the initial fire-fighting.The principle to select the effective water volume of it is identical to that in the selection of the water storage for a high-position fire-fighting water tank.Upon Clause 8.44in GB/T50016-2006Fire-fighting standard in building design ,When the indoor fire-fighting water quantity is less or equal to 25L/s and,via calculation,the water quantity in a fire-fighting water tank needs to be more than 12m ,it can still adopt 12m ;and,when the indoor fire-fighting water quantity is bigger than 25L/s and,via calculation,the water quantity in a fire-fighting water tank needs to be more than 18m ,it can still adopt 18m
