fire fighting pump room details

 

Fire pumps are the primary component of an automatic sprinkler system that feeds fire sprinklers. These pumps operate by using various energy sources such as electricity, diesel, or steam, and are usually connected to a fixed water source. The suction line of the pump is connected to a fixed water source such as water tanks.

The pump's function is to supply a high-pressure water stream to standpipes connected to water sprinklers and fire hoses. These pumps are inspected and tested by international accredited agencies such as UL and FM, to ensure their quality and effectiveness.

Fire pumps can be powered by either an electric motor or a diesel engine, and in some cases a steam turbine can be used.

The fire pump starts operating when the pressure in the automatic sprinkler system drops significantly, which happens when fire sprinklers are exposed to temperatures exceeding their design rating.

This causes them to open automatically and allow water to pass through. Opening water hose reels or other fire-fighting connections leads to a decrease in pressure in the pipe network.

During a fire, the Jockey Pump starts working to compensate for the loss in pressure within the network, but if the drop in pressure is large and the amount of flow required is greater than the capacity of the Jockey Pump.

 This pump stops working and the main electric pump starts working to provide the required flow and pressure in the system. The main pump continues to work until its desired goal is achieved. In the event that the electric pump fails to provide the necessary pressure and flow or an electrical outage occurs, the diesel pump takes over work automatically and does not stop unless it is stopped. Manual.

Fire pump room specifications

An overview of the specifications and design of the fire pump room 

• Main Pump
• Standby Pump
• Jockey Pump

1. How pumps work:

• The main pump is responsible for supplying the network with the required pressure and flow rate according to the system design. In the event of a fire, only one pump starts working, which is the main pump if it is working properly.
• The backup pump turns on automatically in the event of any fault or malfunction in the main pump, to ensure that the network continues to be supplied with the required pressure and flow rate.
• A jockey pump is a compensatory pump, which operates when a leak occurs in the network, and its goal is to maintain constant pressure in the system. Its pressure is set to be equal to or slightly higher than the main pump pressure, but at a flow rate equal to 10% of the main pump flow rate.

2. Control system:

• The design of the fire pump room comes with each pump equipped with its own control panel that contains a pressure switch. A line is taken from the package of each pump called the sensing line to connect it to the pressure switch on the control panel. One flush head pipe can be used for all pumps.

3. Operating mechanism:

• When assuming that the network pressure is 10 bar, for example, and in the event of a leak, the pressure in the network decreases, so the jockey pump starts working to compensate for the loss.
• In the event of a fire, the sprinklers open, causing the pressure to drop even further. The jockey pump starts working, but when it is unable to supply the necessary amount of water, the main pump kicks in to compensate for the pressure and water in the network. If the main pump cannot be operated for any reason, the backup pump is operated.

4. Additional specifications:

• All fire pumps are centrifugal type.
• The jockey pump is always equipped with an electric motor.
• Main and backup pump can Turn them on With an electric motor, but in the event of a fire or power outage, the backup pump will not work. Therefore, it is preferable to have an alternative power source to the main pump.
• The backup pump can be powered either by the building's own generator or by using a diesel engine, which is the most common solution. In some private facilities such as oil companies, the backup pump is equipped with its own generator.

5. Jockey Pump Design:

• The jockey pump is often of the vertical type and multistage, because it requires high pressure to compensate for pressure losses.

6. Fire water tank:

• The fire water tank is often concrete and divided into two parts and uses an independent suction line for each part. This line includes a strainer and an OS&Y gate valve, and is then connected to the pump suction head.

7. Draw line calculation:

• The volume of the tank intake line can be calculated using the equation Q = V × A, assuming a flow speed of 2 meters per second.

Fire pump room components

This set of fire pump room design is not one of the main components, but is designed and implemented by other parties within the fire pump room:

•  Pump Base
  • Concrete foundations designed and implemented by the structural engineer to install the pumps on.
•  Pump Room Access
  • Each pump room must have two entrances, one to enable people and maintenance technicians to enter and exit, and the other to facilitate the disembarkation of heavy equipment and engines.
• Trench and Floor Drain
  • These are the ground drainage points that collect the leaking water in the pump room. The water is collected in a small tank called the well, where submersible pumps called Submersible Pumps are installed. These pumps work automatically when the floats reach a certain level of water, through signals sent by the control panels because the room level Pumps are usually lower than the main drainage network, which requires the use of this method.
• Overhead Crane 
  • Used in large pump rooms To move Heavy ingredients.
• Exhaust Fan
  • It constantly renews the air inside the pump room to ensure good ventilation.

fire pump room design

Fire pump room design or fire pump room dimensions is one of the most important elements within fire fighting systems, as a group of factors are taken into account in order to ensure the efficiency and safety of the system. Here are the most important elements for designing a fire pump room.

• Location and space
  • The pump room must be far from sensitive and dangerous areas in the building and have sufficient space to facilitate access to the pumps for periodic maintenance. It is also preferable for the room to be close to the water source to reduce loss of pressure.
• Access and entry Pump Room Access
  • The room must contain multiple entrances, one for the entry of individuals and technicians for maintenance, and another for the entry of heavy equipment or engines in the event of the need to replace or repair some parts.
• Ventilation
  • The pump room must be provided with a good ventilation system to constantly replenish the air and prevent high temperatures inside the room.
• Pump Base 
  • A concrete base is built under each pump to ensure its stability and reduce vibrations. The base must be designed to bear the weight of the pumps and take into account the appropriate distribution of loads.
• Drainage System
  • The fire pump room is designed with a drainage system that includes drainage channels and a Trench and Floor Drain, where excess or leaking water is collected in a small tank called a cistern using a submersible to drain it automatically.
• Overhead Crane
  • In large rooms containing heavy equipment, an overhead crane is installed to facilitate the process of transporting and moving heavy equipment inside the room, such as large engines or pumps.
• Basic components of pumps
  • The room must contain a main pump, a standby pump, and a jockey pump. Each pump performs a specific function in different situations.
• Basic electricity for pumps
  • The fire pump room is designed with isolated electrical systems to operate the pumps, with control panels for each pump. These panels must contain pressure switches to control the automatic operation of the pumps according to the pressure state within the network.
• Insulation and fire protection system
  • It is preferable to use heat and moisture insulating materials in the design of walls and floors, while providing self-extinguishing systems inside the room for protection in the event of a fire.
• Water tank
  • It is preferable to design the water tank to be close to the pump room to ensure a continuous supply of water. The tank is divided into two parts with an independent suction line for each part to ensure a continuous supply of water to the pumps.

The design of the fire pump room depends on meeting performance and efficiency requirements to ensure the continuity of the system’s operation in emergency situations. It is necessary to adhere to international and local standards to ensure the safety of individuals and the building.
