【 Weak current College 】 role fire water pumping station

Where the responsible fire service tasks of a pump house are referred to as the fire pump room. The fire pump room, press function into pulled water pumping station, pumping and compression pump House; press the use purpose into life, production, fire fighting and pumping stations (such as water-plant), production, fire fighting and pumping stations (such as industrial enterprises), life, fire combination pump (such as civil buildings), an independent fire pump room (such as tank farm).
1. the layout requirements suction pipe
(1) in order to ensure the fire pump not asked a group of broken water supply, fire pump's suction pipe should not be less than two. When one of the damage, the rest of the suction pipe will still be able to pass all water consumption.
(2) temporary high voltage or high pressure fire water system, its each fire pump (working pump and spare pump) should be independent of the suction pipe. From the fire water tank (or the municipal network) direct water intake, ensure supply fire water.
(3) when the water level below the shaft (or absorbent well) when the water level, called since irrigation-water. The fire pump use since irrigation-water. When using irrigation-water, the suction pipe should be set valve for easy maintenance.
(4) in order not to make any accumulation of air suction pipe, due to the pump's suction pipe gradually rising slope, generally use the greater than or equal to the slope of the costing.
(5) the suction pipe and water pump connection, should not make any accumulation of air suction pipe.
(6) the suction pipe in water wells (or pool) and shaft, shaft should be at arm's length.
(7) the suction pipe diameter should be greater than the diameter of the pump inlet.

2, water pipe layout requirements
To ensure that pipe have reliable water source, when the fire pump outlet pipe and pipe connections, the outlet shall not be less than two. When one of the outlet pipe repair, the rest of the outlet pipe should still be able to supply all of water demand.
Fire pump outlet check valve should be set. At the same time as the water pump lubrication, start quickly, the pump outlet should be located to check and test on the water valve, test used water, can be placed back to the fire water tank.

3, the alternate fire pump
Spare pump is the work of pump malfunction or maintenance of the pump when operational. It and work with each take turns running pump, mutual as a spare.
In order to ensure uninterrupted supply of water for fire, the fire pump should be equipped with standby pump. Spare pump flow rate and head should be not less than the fire pump maximum one pump flow rate and head. But one of the following conditions may not equipment with pump:
(1) outdoor fire water consumption not exceeding 25Vs factory, warehouse or residential area;
(2) seven to nine layers of modular homes.

4. power supply requirements
The fire pump should ensure that the fire starts after 5 minutes, and after a power outage is still properly.
There are alternate fire pumps in factories, warehouses, offices, schools, and other power supply for:
(1) consists of two power supplies, respectively, independent of the bus-powered;
(2) with two independent bus-powered by ring circuit;
(3) in the power equipment used by linkage to green electricity;
(4) to set up the standby pumping engine, etc.
No device pumps used in factories, warehouses, offices, schools, and other units, the fire pump can use a power supply by independent bus, but consideration should be given to the fire cut off power to the unit other still should ensure that the fire pump to supply electricity lines.
In order to ensure the fire pump can play a load operation to ensure that the fire had the necessary fire fighting water and water pressure, fire pumps and power machinery should direct coupling, flat belts should not be adopted, because the flat belt easy slipping, affecting water supply capacity of fire pumps, such as when using triangular belt should not be less than four.
The fire pump room should be equipped with the fire brigade is directly linked to the communication device.
