【 Weak current College 】 fire water system debugging points

(A) fire hydrant system debugging

1. system debugging should be in the system construction completion

(2) the system power is normal;
(3) air pressure tank and water level, and pressure comply with the design requirements; all valves are not leaking phenomenon;
2. fire pump function
(1) open water pump outlet on water test valve; to automatically or manually using the main power, when booted the fire pump; the fire pump shall be put up and running within 5min;
(2) turn off main power, standby power supply automatic switching function, the fire pump shall be put up and running within 1.5min; turn off the power switch; preparation of the master, the normal chewing conversion starts;
(3) pump test running continuous time should not be less than 2h, water pump running smoothly, no abnormal sound, and should meet the following targets:
A fire in the design, condition, flow and pressure parameters meet the design requirements values;
B, in fire-fighting early working conditions, to the extent permitted pressure rise; and the safety relief guarantees;
C, motor current at rated range;
D, roller bearing temperature not higher than is the degree; sliding bearing temperature a few degrees temperature normal gland packing;
E, sealing parts of non-disclosure, the fastening parts no loose.
3, test fire water system linkage
(1) in the fire control centre of the fire control cabinet manually started the fire pump; the fire pump starts and displays properly;
(2) open the roof test fire hydrant water; or open any floor of a fire hydrant, and press the Start button, fire pumps, fire pumps can be started directly into normal operation; fire control rooms according to Kai pump button signal manually started the fire pump; the fire pump start properly run; the fire pump startup; fire box with pump start feedback signal display.
4. fire-pressure water sharing equipment during normal operation, turn right on the water hydrant; check the stable pressure limit, limits, and regulators start and stop controls and when the pressure drops to stable pressure lower following a given value is automatically shipped main fire pump control function, three kinds of pressure control function should conform to the specifications and design requirements;
(1) on boosting stabilizing device; check the stability of pressure on the upper and lower control functions should conform to the specifications and design requirements;
(2) the fire-pressure water sharing equipment and boosting voltage devices, normal voltage maintenance over time should 1h; buqi functions properly;
5, press water partition test pressure: inside and outside the network supply
(1) test outdoor hydrant most unfavorable points for fire protection design of water pressure should be consistent with the design requirements; meet outdoor fire water pressure;
(2) test the water room partition the top and bottom fire hydrant for fire protection design of hydrostatic pressure, started the fire pump pressure, after the water shall be subject to the specifications and design requirements;
(3) test the water room partition middle tier installed and not installed pressure orifice plate, adjacent two-storey fire hydrant for fire protection design started the fire pump pressure, after the water shall be subject to the specifications and design requirements.

(Ii) automatic sprinkler system debugging

1. General system debugging provides as follows:
(1) automatic sprinkler system debug should system construction completion;
(2) automatic sprinkler system debug should meet the following conditions:
A fire water tank, fire water tank design volume has reserves;
B, the system power is normal;
C, pressure tank water level and pressure comply with the design requirements;
D, wet sprinkler off one system network has been filled with water; all of the pieces are not compromised asked phenomenon;
E, and the system of automatic fire alarm system is permitted.
2. debugging content and requirements:
(1) automatic sprinkling debug reads as follows:
A, water testing;
B, fire pumps and debugging;
Debugging c, regulators pumps;
Debugging between d, alarm;
E, drainage device for debugging;
F, linkage experiment.
(2) water test:
A, as designed to verify the volume of fire water tank; set the height and guarantees fire water storage is not used by technical measures;
B, as designed to verify the number of pump adapter and supply capacity, and through mobile fire pump for water testing for verification.
(3) the fire pump debugging:
A, either automatically or manually started the fire pump. Pump should be put into running within 5min;
B, once the switch is in the standby power supply; pump should be put into normal operation in the 90s; turn off the power switch on the pump, main, start normal by pump conversion;
C, pump running continuous time should not be less than 2h. Smooth running, is sound. Water pump performance meet the design requirements; initially to fire conditions pressure rise in the allowable range, and a guarantee of safety relief, motor currents within the rated value; bearing temperature rise and so comply with the requirements;
D, in fire control room manual pump, water pump buttons restart normal startup; fire control room Kai pump feedback signal displays correctly.
(4) voltage pump debugging:
A, simulation design launch conditions, regulators pumps should be started when the system reaches pressure regulators pumps should be automatically stopped;
B, fire-pressure water sharing equipment and pipeline pressure normal stable pressure maintenance time should be in the air above; 1h functions properly;
(5) alert between debugging:
A, open the wet alarm valve side test carried out on the water; water asked when water reaches 60-min 17OL/; alarm when asked timely action,Delay not exceeding siren 90s; hydraulic should alarm signal, the pressure switch should close the circuit signal transmission to the fire control centre alerts; and should be started the fire pump;
B, open alarm valve side main drainage asked, according to the system maximum design fire test of water for water drainage; fire pump is working properly, and can achieve and maintain network design fire conditions work pressure;
C, closed sprinkler system each system's top, bottom and middle-tier distribution system is not placed end-to-water appliances is about a nozzle flow, pressure should not be lower than 0.1Mpa.
(6) drainage equipment test:
A, full open drainage device of main drainage, according to the system maximum water volume for drainage design tests; and the pressure to achieve stability;
B, the entire testing process, the release of water from the system should be all from indoor drainage system discharge, shall not cause any water.
(7) the joint test:
A special test instrument, or otherwise, on the automatic fire alarm system each kind of detector input analog signal fire, fire auto-alarm controller should emit sound and light alarm signal and start the system;
