The automatic sprinkler system mainly detects the situation of the system from two main aspects: water volume and water pressure.
1. Inspection of fire pool
The fire pool shall not be mixed with other facilities, and the water shall be replenished in time when conditions permit. In order to prevent the freezing of the automatic fire extinguishing system caused by the low temperature in some areas, the anti freezing system must be improved; the water level and gas pressure of the fire pool shall be checked regularly every month, and the water supply capacity must be sufficient, meeting the design requirements. If the inspection results show that the pool is damaged and paint has fallen off In case of any defect, repair the damage and repaint the paint immediately;
Regularly check whether the water test valve is open and meets the standards; all kinds of water pump control instruments and adapters must be marked with their production areas and dates, and have regular signboards, and the fire pump must be tested regularly to ensure that there is enough drainage capacity; all kinds of pressure pump control valves must be opened frequently to ensure normal operation; the water flow indicator must be equipped with Regular business logo, and ensure that the control valve has a good signal, can correctly display the water level at that time.
At the same time, the water level index in the fire pool must be normal; the control water supply valve must be always in the open state; the interface of the water pump adapter and its accessories must be intact, without leakage and complete equipment; the obstacles at the nozzle should be cleaned in time; the pipe network should be cleaned regularly to ensure that there is no dirt; the alarm valve should be checked regularly to see if it is open, and the alarm valve should be tested regularly every quarter; it should be fixed every month It is required to inspect the appearance of the sprinkler regularly. In case of leakage and dirt at the sprinkler, it is required to handle it in time. All kinds of sprinklers shall be equipped with certain spare parts to prevent emergency. The display function of the system shall be checked regularly to ensure clear signal is transmitted to the fire control room in case of emergency, and the change-over switch of the system shall be checked regularly.
2. Regular use of equipment for inspection
Regularly use testing instruments to test displays and other detector equipment in batches;
The equipment with alarm function and display signal, such as pressure switch and water flow indicator, shall be strictly tested to ensure normal alarm in case of emergency and make emergency plan.
