Fire fighting pump calculation pdf

TRAINING THE FIRE SERVICE FOR 1YEARS. Fireengineeringuniversity. Ultra-High Pressure (UHP) Pump.

Overview Modern fire apparatus pump systems are comprised of many components utilized to move and control water from a source. Total head pressure required = 6. Identify the components of a fire pump and driver.

Describe the purpose of the various components of a fire pump and driver. Discuss the variables that impact the layout of a fire pump and how they are addressed. Elements used in the calculations 3. Zero suction lift has been assumed for all calculations.

GenSize for the fire pump motor, establishes a maximum allowable Peak Voltage dip of while starting the fire pump load (all fire pump loads will be included in the peak load calculations ) after all other loads are already running on the generator. Horizontal elbows or tees upstream of a fire pump must be pipe diameters from the suction flange on a split-case fire pump. Pumps must maintain a positive suction pressure at the suction flange. Automatic Sprinkler System Calculations Russell P. FIRE PUMPS DESIGN AND CONSTRUCTION STANDARD 1.

Upon completion of the pump and sprinkler piping installation, a field acceptance test shall be conducted at minimum, rate and peak loads of the fire pump by controlling the quantity of water discharged through approved test devices. Put Your Trust in the Top Brands. A Jockey Pump is an important component of a fire pump system. The Jockey Pump is not as mundane as many engineers, contractors, and installers would have you believe. Why are they so misunderstood?

A fire pump is a device that provides the required water flow and pressure for a fire protection system. The fire pump unit itself consists of a pump , a drive, a driver coupling connecting the two, and a base plate. If operating personnel are on the level where the fire occurs, the first reaction is to run to the stairway. Therefore, the most accessible points for the location of the major fire fighting equipment is the stairway area of each deck. Each pump is tested hydrostatically for not less than minutes.

IMPELLER BALANCING The impellers of each pump are dynamically balanced to the. The pressure at the highest outlet of a wet riser A wet riser is provided in an 8-storey building with an outlet at every storey. The highest outlet is 26m above the fire fighting pump , see Figure below. Various types of fire pumps are used in fire protection systems.

Types of fire pumps include: horizontal split case, vertical split case, vertical in-line, vertical turbine, and end suction. Passive fire protection arrangements, such as structural fire protection, as well as fire detection systems, are outside the scope of this document. CHAPTER WATER DISTRIBUTION SYSTEMS Distribution system is a network of pipelines that distribute water to the consumers.

Before we answer the quetion, it’d better to understand what jockey pump is and what the function in fire fighting sytem.

A jockey pump is an important component of fire fighting system. It maintains pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause an appreciable pressure drop which will be easily sensed by the fire pump automatic controller.
