Summarize:
A fire pump is a part of a fire sprinkler system's water supply and powered by electric, diesel or steam. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes.
Yonjou can make the fire pump with NFPA20 standard.
Fire pumps function either by an electric motor or a diesel engine, or, occasionally a steam turbine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize, when connected via a listed transfer switch, the installation of an emergency generator.
Service condition:
| Atmosphere |
>90kpa |
In abnormal condition, engine rated power may lower then normal.
Ensure working safe, a bigger engine required at work is better.
Note: Measurement of engine rated power is tested in following condition. |
Atmosphere |
=100kPa |
| Ambient temperature |
5-40ºC |
Ambient temperature |
=25ºC |
Relative air humidity |
=30% |
| Relative air humidity |
≤80% |
Every 100m altitude higher the rated power of engine drop 3%. |
| Applicable diesel engine |
Engine rated power 10% more then pump absorbed power |
Every 5.6'C ambient temperature higher the rated power of engine drop 1%. |
| Engine real power output=(CA+CT-1)x Rated power |
