How does a fire pump controller work?

The devices within a fire pump controller panel perform such functions as receiving signals from alarm devices, such as pressure operated switches, sprinkler alarm valves or remote fire alarm equipment; activating motor control devices to provide electric power to motors driving fire pumps and monitoring the fire pump …

What activates a fire pump?

Main Fire Pump Pressure Switch The turn-on for the main fire pump is a water pressure switch. When there’s a fire, sprinkler heads are going to activate and spray water. This loss of water in the sprinkler system causes the pressure to drop. When the pressure drops, the main fire pump turns on.

What is a pump controller?

Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc.

What is a jockey pump controller?

These controllers are intended for use with fire pump systems. Jockey pumps are small, motor driven pumps used in conjunction with main fire pumps to compensate for minor leaks in the fire protection system and automatically maintain stand-by pressure.

How do you adjust a pressure switch on a fire pump?

PRESSURE SETTINGS The National Fire Protection Association recommends that the jockey pump (if utilized) be set to shut off at “pump churn” pressure plus the minimum static pressure on the suction side of the pump. Set the jockey pump start pressure at approximately 10 psi less than the jockey pump shut off pressure.

What is a fire pump set?

The pump sets provide a higher pressure of water flow for the sprinkler system risers and hose standpipes. The fire pump activates when the pressure in the fire sprinkler system drops below the baseline.

How do you start an emergency fire pump?

Starting the pump:

  1. Check the suction valve is fully open.
  2. If a pump is of self-priming type (with a vacuum pump), ensure the supply tank containing the priming water is full.
  3. In centrifugal type fire pump, close the discharge valve and open the air vent on the volute casing.
  4. Close the vent once water comes out.

When should I use RPM mode?

The rpm mode will allow the pumper to continue to operate if a pressure sensor clogs or fails and will allow constant engine speed operation for certain types of equipment like some types of CAFS or other engine driven equipment that need a relatively fixed speed for best performance.

Do you need a pump controller?

Here are some of the essential applications of an automatic pressure controller: It controls the pump to ensure it runs at a constant flow. When showering at home without a pressure pump or automated pressure control, you might notice the water’s inconsistent temperature or intermittent water pressure.

How does a fire truck pump work?

You control the hoses using the truck’s pump panel on top of the fire engine. The pump panel is a series of levers and switches that controls how much water is flowing and which lines are being discharged. When arriving at a fire scene, the driver will jump out and climb to the top of the truck to begin pump operation.

How do fire engines work?

How Fire Engines Work. The heart of the pump/tanker is the impeller water pump. On this particular fire engine, the pump is located just behind the jumpseat area, where the firefighters sit. An impeller is a rotor-like device that has curved blades. Driven by its own diesel engine, the impeller spins inside the pump at a high rate.

What is the purpose of a pumper fire engine?

The walls of these pipes are rigid so that the suction of the pump does not collapse them. The primary function of any pumper/tanker fire engine is to carry water in a water tank or suck water in from an outside source, such as a fire hydrant, drop tank, swimming pool or lake.

How do you control the hoses on a fire truck?

You control the hoses using the truck’s pump panel on top of the fire engine. The pump panel is a series of levers and switches that controls how much water is flowing and which lines are being discharged.
