The fire pump booster, by maintaining the water pressure at a predetermined value, compensates this pressure drop in the event of a pressure drop in the system, which is sensed by the sensors installed on the pump booster. Information about this event is transmitted to the switchboard. If a jockey pump is also present, it enters the circuit first and corrects the pressure drop.
If the required flow rate is greater than the ability of the jockey pump and a greater pressure drop occurs in the circuit, the control panel will issue an order to run the main pump. The main pump is automatically turned on to increase the pressure of the system with the help of the jockey pump. The main booster pump of the fire pump remains in the active circuit as long as the fire extinguishing system needs water, and whenever the pressure switch detects the pressure value, the corresponding signal is sent to the electrical panel.
The control panel also issues the command to start the electric motor/diesel pump motor. If the main pump cannot be turned on for any reason, the reserve pump is added to the circuit by the command of the electrical panel and plays its role as a system pressure supplier. It is important to note that the fire pump booster is not the only source of water supply for firefighting and its task is to provide the required pressure of the system.
For the fire pump booster, considering that the urban water flow rate is usually lower than the flow rate required for the fire extinguishing system, it is necessary to consider a water source or tank with a suitable flow rate for the project. The main purpose of exploitation And the use of booster pumps is to create appropriate water pressure in different parts of a complex or to provide water flow in a desirable and constant range.
Booster pump, as one of the main equipment for increasing water pressure and injecting it into water supply system or fire extinguishing system, plays a very important role in this field. The most important difference between fire booster pump and water supply pump booster is the type of pump used in each of them, which may be according to the type of pump used in these two types of booster pump, fire pump booster and water supply booster pump can be respectively fixed speed booster pump and Also called variable round.
Due to the use of a constant speed pump, the fire pump booster has a pressure switch and does not have an inverter and a pressure transmitter, but the variable speed (water supply) model has an inverter and a pressure transmitter in its electrical panel. Of course, be careful, it is not necessary to use a fixed-speed booster pump in the fire-fighting pump booster, and you can also use a variable-speed booster pump. It should be kept in mind that the fire pump booster is used for emergency situations, but the water booster should be designed in such a way that it has the ability to supply water continuously.
For each pump, two pressure switches are installed in the fire pump booster, one of the switches is a backup and standby for the other. The reason for this is that because the fire pump booster is off for a long time and only starts when there is a fire, for this reason we must have two pressure switches for each pump, so that if one of them fails, the other one enters the circuit.
A fire pump booster should consist of three components consisting of an electric pump, a diesel engine and a jockey pump, but these components are not essential in the water supply pumping system. In the fire pump booster, each pump has a separate diaphragm source on the fire line, but this is not the case in the water supply pump booster.
In booster components of fire pumps, a separate electrical panel for each pump must be installed. But this is not the case with booster pumps, and usually an electrical panel is responsible for controlling the booster pump system.
