5 system appearance inspection

Managing maintenance personnel should be daily visual inspection of the system, and should fill out inspection records. Check content including:

1. view the fire water tank (or tank) appearance, fire pumps and control cabinet work status, regulators pumps, pump, pressure tank work status, pump house work environment; view the fire pool water and fire water not being his facilities; view water facilities; view from freezing facilities; view fire water tank water and fire water not being he's facilities.

2. view the appearance of foam nozzle, the appearance of foam fire hydrant, foam Cannon appearance, the appearance of foam generator, the foam liquid storage tank foam liquid between environment, tanks for appearance, appearance, foam proportioner pump status.

3. view the pump control cabinet instruments, led, control buttons and logos; analog master pump failure, view the automatically switch standby pump while viewing instrument and led display.

4. view the foam liquid storage tanks or nameplate, signs should be clearly marked on the foam type, ratio of concentration, foam extinguishing agent's effective date, and reserves; tank fittings should be complete intact, level gauge, breathing valve, safety relief valves and pressure gauge status should be fine.

5. checkSee proportioner meets the design selection; flow direction correctness; valves, pressure gauges should be flexible.

6. view the foam generator meets the design selection; breathing hole, foam and foam injection port exposed without sundries or plug; bubble near the exit without barrier foam injection and foam flowing obstructions.

7. view the foam plug valves are flexible; therewith meets the design selection, breathing hole, foaming network is blocked.

6 system of weekly, monthly check test

1, every week, responding to the fire pump and standby power to start the test at a time.

2. monthly deal with low, medium and high expansion foam generators, foam nozzle, stationary foam Cannon, foam proportioner (device), the foam liquid storage tanks for Visual inspection should be intact.

3. monthly deal with stationary foam Cannon Rotary institutes, back down or motor-operated institutions for checks, performance should meet standard requirements.

4. monthly deal with foam fire hydrant and valve for a check valve open and close should freely, not rust.

7 system of half-yearly and annual check test

1. system in addition to the half-year storage tank foam mixture risers and liquid injection foam pipe within the fire-dike and high expansion foam generators import-control valve after the pipeline, the pipeline should all cleaning, removal of rust residue.

2. system should carry out a check test starts automatically. Check the test method: low, medium expansion foam fire extinguishing system select a most unfavourable protection area, high-expansion foam fire extinguishing system, a protection zone selection so that the protective area smoke and heat detector separately issued analog fire signal, observe and record the foam fire extinguishing device actions and related facilities actions and control room fire control equipment signal display. Standard requirements: when the protective area smoke detector issued fire alarm signal, control room fire control equipment should receive and issue the sound, light and alarm signal detector parts; when the protective zone heat fire detectors emit fire alarm signal, control room fire control equipment should receive and issue the sound, light and alarm signal detector parts, protection area sound, light alarms should alarm, fire control equipment should be issued started the fire pump or stationary fire control pump group, open the protective zone of the control valve, foam extinguishing device directive automatically starts injection (injection should not be less than 1 minute). At the same time, the protective zone, drowned in the depth of the foam doors, Windows should automatically close, in the closed space of the vent should be automatically turned on, the relevant production, lighting, power should be severed. Each part of the action time and action state should correspond to the design requirements. Control room fire control equipment should have the foam Jet and the martensii action state feedback signal display.

3, the system should have a remote boot test. Check the test method: in the control room fire control device to manually start a protection zone of foam fire suppression equipment, observation of foam extinguishing device actions and related facilities actions and fire control equipment signal display. Standards: in the control room fire control devices manual start foam fire suppression equipment, protective zone of sound, light alarms should alarm, foam extinguishing device should start blasting, protective zone of doors, Windows should automatically closes, closed space of the vent should be automatically turned on, the relevant parts of the production, lighting, power should be severed. Control room fire control equipment should be foam injection and each part of the action signal display.
