yes
A Dry Riser is a system of valves and pipework which enables the Fire Service to pump water on to the upper floors of a building. A Wet Riser is a system of valves and pipework which are kept permanently charged with water.
A malfunctioning fuel injector pump will cause the injectors to not fire properly. The fuel injector pump will need to be replaced.
Landing Valve is present inside the building in every floor of a mid and high rise building. Usually it is found inside the fire hose cabinet with fire hose reel on top and landing valve in the bottom with its hose detached for civil defense experts to use in case of an emergency. Breeching inlets are usually found in the ground floor for the civil defense vehicle to come and have direct access to pressurize the riser using external pump present in the vehicle. It can be both wet riser and dry riser. Wet riser will have water till the inlet. The output of the breeching inlets are the landing valves.
There is no 'standard' for UK dry risers - except for the connection at street level, the pipe can be any diameter. A dry riser is a (usually empty) vertical pipe - which reaches all floors in a tall building. The fire brigade simply connect a hose from their pump engine - which has been connected to the nearest mains water supply. The engine provides enough pressure to force the water upwards in the dry riser - so it reaches all levels.
The fire pump churn test, is when an operator runs the fire pump without the flow of water
A jockey pump is a small pump connected to a fire sprinkler system and is intended to maintain pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause a pressure drop which will be sensed by the fire pump automatic controller, causing the fire pump to start. The jockey pump is essentially a portion of the fire pump's control system.
most likely a fuel pump. you should be able to hear it cycle when you turn the key on if not its the pump.
No. it is a single cock spring system. You only need to break the barrel once to cock it and fire it.
Did you mean Jockey Pump which is a small pump connected to a fire sprinkler system and intended to maintain pressure in a fire protection piping system to an artificially high level so the operation of a single fire sprinkler will cause a drop in pressure that will be sensed by the fire pumps automatic controller, causing the fire pump to start. The Jockey Pump is essentially a portion of the fire pumps control system.
You did not say what year it is are what it is, So I can't help you like I would like to. But you need to start with the fuel pump relay and the fuse for the fuel pump. If I knew what you were working on I would tell you where that stuff is. NEUTZ.
Not a lot. A fire fighting pump found on most fire engines is the centrifugal type. Other than the amount of water it may flow and the number of discharges it can supply, there is no difference (although I'm not sure what "ordinary centrifugal pump" refers to unless it is a trash or sump pump). Centrifugal type pumps weren't always used in the fire service, but they are the standard now because they can spin (they can pump or maintain pressure) even when there is no water actually flowing.
test for power to fuel pump. sounds like you need a new coil as well
