There are some key design and layout points of fire pump house,today we will talk this topic!
The fire water pump room shall be equipped with lifting facilities and shall meet the following requirements:
① When the weight of fire pump is less than 0.5T, fixed hook or movable hanger should be set;
② When the weight of fire pump is 0.5t-3t, it is better to set up manual lifting equipment;
③ When the weight of fire pump is more than 3T, electric lifting equipment shall be set.
The layout of fire pump unit shall meet the following requirements:
① Clear distance between two adjacent units and unit to wall:
When the motor capacity is less than 22KW, it should not be less than 0.60m;
When the motor capacity is not less than 22KW and not more than 55kW, it should not be less than 0.8m;
When the motor capacity is more than 55kW and less than 255kw, it should not be less than 1.2m;
When the motor capacity is greater than 255kw, it should not be less than 1.5m.
② When the fire pump is overhauled on site, at least one side of each unit shall be provided with a passage with the width of fire pump unit plus 0.5m, and it shall be ensured that the fire pump shaft and motor rotor can be disassembled during the overhaul.
③ The main channel width of fire pump house shall not be less than 1.2m.
When there is a centralized maintenance site in the fire pump room, its area shall be determined according to the overall dimension of the water pump or motor, and a passage with a width of not less than 0.7m shall be reserved around.
The underground pump house should be equipped with a centralized maintenance site.
For the wet shaft pump room equipped with deep well water pump, a place for stacking pump pipes shall also be provided.
The fire pump should not be set on the upper floor, the next floor and adjacent positions of rooms with anti vibration or quiet requirements. When necessary, the following noise reduction and vibration reduction measures should be taken:
① Low noise water pump shall be adopted for fire pump;
② The fire pump unit shall be equipped with vibration isolation device;
③ Vibration isolation device shall be set on the water suction pipe and water outlet pipe of fire pump;
④ Measures shall be taken to prevent solid sound transmission at the places where the pipe supports and pipes pass through walls and floors in the fire pump room;
⑤ The technical measures of sound insulation and absorption shall be taken for the inner wall of fire pump room.
