What is pump theory?
Pumps are an integral part of many pressure systems. Pumps add energy, or head gains, to the flow to counteract headlosses and hydraulic grade differences within the system. A pump is defined by its characteristic curve, which relates the pump head, or the head added to the system, to the flow rate.
What is a fire pump driver?
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 is fire fighting pump?
A fire pump is a part of a fire sprinkler system’s water supply and powered by electric, diesel. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake).
What activates a fire pump?
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 are the three major types of fire pumps?
What types of fire pumps exist? Centrifugal pumps are most commonly used in fire protection systems, these include: horizontal split case, horizontal end suction, vertical turbine and vertical in-line. These pumps are commonly powered either by an electric motor or a diesel engine.
What is concept of pump?
1 : a device that raises, transfers, delivers, or compresses fluids or that attenuates gases especially by suction or pressure or both. 2 : heart. 3 : an act or the process of pumping. 4 : an energy source (such as light) for pumping atoms or molecules.
What is the function of the pump?
A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system.
What is the pressure of fire pump?
Fire pumps are rated by the manufacturer to produce a certain amount of net pressure (typically between 40 and 250 psi) at their rated flow. It is important to note that the rated net pressure usually only occurs at the rated flow of the pump.
What are the different types of fire pumps How does each work?
Types of fire pumps include: horizontal split case, vertical split case, vertical in-line, vertical turbine, and end suction. These fire pumps may be powered by an electric motor or diesel engine and on rare occasion powered by a steam turbine.
What is a commercial fire pump?
A fire pump is a crucial component of many commercial building owners’ overall fire and life safety plan. Fire pumps provide fire sprinkler systems with an extra boost of water pressure to ensure the system receives the required amount of water to douse fires and prevent reignition thoroughly.
What are the types of fire pumps?
Common types of fire pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.
