What is the role of diesel engine fire pump?

All places need to be equipped with fire-fighting facilities, and fire pumps are necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between the two is The electric fire pump needs to be supplied by the power system. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original electric fire pump.

In smart buildings, the latest trends in fire pump technology focus on integrating advanced sensors, IoT (Internet of Things) capabilities, and data analytics to enhance system performance and reliability. Smart fire pumps can communicate with building management systems (BMS) to provide real-time data on pump status, water flow, pressure, and other key parameters. This data can be used for predictive maintenance, alerting operators to potential issues before they become critical. Additionally, smart pumps can adjust their operation based on real-time conditions, optimizing energy use and ensuring the most efficient response during a fire emergency. These technologies enhance safety and align with the broader trend toward more intelligent, automated, and energy-efficient building systems.

The diesel engine fire pump is suitable for unattended emergency water supply systems. The product has the characteristics of good technology, high degree of automation, superior performance, complete protection functions, reasonable structure, simple installation, and high cost performance. pipe network pressure.

The diesel engine fire pump set has the characteristics of high degree of automation, superior performance, complete protection functions, reasonable structure, simple installation, and high cost performance. When the factory suddenly fails, the diesel engine emergency water supply pump set will automatically start to supplement the pressure of the pipe network.

Our customer from Philippines ordered 2 sets small flow fire pump set Last month. The flow and head of this small fire pump set is 50gpm and 5bar. This electric fire pump system only includes electric fire pump and jockey pump.

Fire pumps are more expensive than ordinary water pumps because they must meet specific fire protection standards and are built to handle high temperature and pressure water. They also have additional features, such as larger motors, to rapidly provide the necessary flow rate to meet fire protection requirements.

Double power fire pump product advantage is that when a fire occurs, a more reliable way to ensure water safety, in the normal power supply when the electric pump group into work, when the power supply failure, the electric fire pump can not be normally put into use, the diesel fire pump group can automatically put into operation to ensure the normal fire fighting.

1. Electric fire pump: various end suction pumps and split pumps.
2. jockey pump: vertical, small flow, higher lift than electric or diesel pumps.
3. Control panel: Automatically control the water pump with overload and overcurrent protection.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, flexible expansion joint, pressure switch, pressure gauge, base, etc.

Prior to installation, fire sprinkler systems are hydraulically calculated to ensure adequate water flow and that the system can reliably suppress a fire until fire crews arrive. When it is determined that there is insufficient flow from a municipal supply for the system to function properly, a fire pump is installed. The fire pump activates when the sprinkler system pressure falls below a certain threshold as a result of sprinkler head operation. To maintain the required operating pressure of the sprinkler system, the fire pump draws additional water from the municipal water supply or on-site storage tanks. Due to the size of piping systems and pressure loss, fire pumps are frequently required in high rise construction and large area buildings.

Diesel engine fire pumps are made of domestic or imported high-quality products. They have the characteristics of good starting characteristics, strong overload capacity, compact structure, convenient maintenance, simple use, and high degree of automation. They are advanced and reliable fire-fighting equipment.

There are many types of fire pumps to deal with more fire water environments. Fire pumps are used in buildings, factories, storage and other places, and the performance requirements and quality requirements are different. The commonly used types of fire pumps are vertical electric fire pumps, diesel fire pumps, horizontal single-stage fire pumps, vertical single-stage/multiple Level fire pumps and horizontal double-suction fire pumps, etc., the specific head, flow and power are selected according to different projects.

First, what’s a water pump? It’s a device used to transport liquid, pressurize the liquid, and make the liquid from the first liquid position to the high liquid position. The first water pump constructed by the Chinese is called” water windmill”. latterly, around 300 BC, the emergence of the” Archimedes screw pump” is more analogous to ultramodern pumps. In addition, the following introductory knowledge points are what you must understand.
1. Centrifugal pump

Centrifugal pump is the most common type of pump. In simple terms, the working principle of centrifugal pump is to rotate the impeller to drive the liquid under the action of centrifugal force. The liquid leaves the impeller and enters the volute. As the inflow passage of the volute gradationally expands, the fluid haste slows down, and the pressure rises continuously, and eventually it’s discharged through the conduit.
2. Impeller
The impeller is one of the main factors in the water pump, and it’s the core element that transmits mechanical energy to the liquid. The impeller is substantially divided into three types open type,semi-open type and closed type. The material conditions for the impeller are high, wear resistance is needed, and the manufacturing process is good.

3. Cavitation

Cavitation is the conformation of numerous bitsy recesses when the liquid connections the liquid under high- speed inflow and pressure, and gradationally expands into grottoes when serious, and cavitation frequently occurs in the impeller and pump covering.
