The main components of the fire pump

In urban areas, where water supply systems may be complex and highly interconnected, fire pumps play a crucial role in ensuring resilience and reliability. These pumps help maintain adequate water pressure and flow across different zones within the city, especially during peak demand periods or in the event of a fire. Fire pumps are often integrated into municipal water systems, providing additional pressure support for firefighting efforts and ensuring that water can be delivered quickly to where it is needed most. In some cases, fire pumps are also used to support the overall stability of the water supply network by compensating for pressure drops caused by infrastructure issues or increased usage.

1. When installing the water inlet pipe, the horizontal section should be horizontal or upward
2. There are many elbows used on the water inlet pipe
3. The water inlet of the water pump is directly connected with the elbow
4. The last section of the water inlet pipe equipped with a bottom valve is not vertical
5. The position of the water inlet of the water inlet pipe is wrong
6. The outlet pipe is above the normal water level of the outlet pool

Jockey pumps help extend the lifespan of fire pumps by maintaining system pressure and preventing unnecessary cycling of the main fire pump. By handling minor pressure fluctuations and small leaks, jockey pumps reduce the wear and tear on fire pumps, which would otherwise start and stop frequently to maintain pressure. This reduced cycling minimizes mechanical stress on the fire pump’s components, such as bearings, seals, and impellers, thereby prolonging its operational life. Additionally, jockey pumps consume less power and operate more quietly than fire pumps, leading to energy savings and reduced noise pollution in facilities. By ensuring that fire pumps only operate during actual emergencies, jockey pumps contribute to the long-term reliability and efficiency of the fire protection system.

EDJ-ISW fire pump is composed of electric pump + diesel engine pump + jockey pump.

As a fixed fire-fighting equipment, the diesel engine fire-fighting pump set has been widely used in fire-fighting diversion, especially for fire-fighting water supply in unexpected situations such as no power supply or abnormal power supply (mains power). The fire pump equipped in the unit is a horizontal single-stage and multi-stage fire-fighting special pump. It is mainly composed of diesel engine, fire pump, connection device, fuel tank, radiator, battery pack, intelligent automatic control panel, etc.

The fire pump is mainly a kind of pump equipment used for fire emergency, and its function is to transport the water source to the fire scene for fire extinguishing. In life, fire pumps are widely used in various buildings, such as factories, docks, warehouses, ports and other places, and are important equipment for fire emergency.

Fire pumps are not always running; they typically start automatically when a drop in water pressure is detected in the fire protection system.

The diesel engine fire pump and the electric fire pump are “one standby and one use”. The control boxes of the diesel engine fire pump and the electric fire pump should be kept independent of each other, and the diesel engine fire pump must be used as the backup pump of the electric fire pump, and cannot be used as backup for each other.

The pump start signal in the fire extinguishing system is directly connected to the electric fire pump control box, and it is not suitable to be connected to the diesel engine fire pump control box at the same time. The pump start fault signal of the electric fire pump control box and the pump start signal in the fire extinguishing system are used as the automatic start pump start signal of the diesel engine fire pump control box, and the line is connected to the control box of the diesel engine fire pump. The pump start failure signal of the diesel engine fire pump control box received an alarm from the fire control center. After receiving the alarm, the authorized personnel rushed to the pump room to force the diesel pump to start in an emergency.

Diesel engine fire pumps are widely used in water supply and firefighting work in the field of firefighting, such as building firefighting, fire fighting, rural firefighting, etc. The diesel engine fire pump has the advantages of quick start, stable operation, large water flow, long service life, etc., and can meet the fire protection needs of different occasions.

Diesel engine fire pump has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. This diesel engine pump set can transport clean water or other liquids whose physical and chemical properties are similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump’s flow parts, sealing form and adding a cooling system.

Fire pumps are designed to adapt to varying water supply conditions, such as fluctuating pressures or varying water levels in a reservoir. They achieve this through features like variable speed drives, which adjust the pump’s speed to maintain consistent water pressure and flow, regardless of changes in the supply.

The pressure switch and control cabinet can automatically turn on/off three pumps-the electric pump and jockey pump operate when there is electricity and the diesel pump activates when the power cuts,can work when the power is off.

The main reason to have a fire pump is to work with the fire protection system in case the water supply does not have sufficient pressure. High structures or large warehouses that carry large amounts of water require the help of a fire pump. It increases the pressure of the water flowing into the fire suppression system, allowing the system to release the maximum amount of water while extinguishing the fire.

Installing fire pumps requires careful planning and adherence to specific precautions to ensure proper functionality and compliance with safety standards. Here are some important precautions to consider during the installation process:

Compliance with Codes and Standards: Familiarize yourself with local fire codes, regulations, and industry standards applicable to fire pump installations. Ensure that the installation meets the requirements of organizations such as the National Fire Protection Association (NFPA) and local authorities having jurisdiction (AHJs).

Professional Installation: Fire pump installations should be carried out by qualified professionals experienced in fire protection systems. Engage licensed contractors or fire protection engineers who specialize in fire pump installations. They possess the necessary knowledge and expertise to ensure a correct and safe installation.

Proper Location: Choose an appropriate location for the fire pump installation. Consider factors such as accessibility, proximity to water sources, electrical connections, and suitable drainage. The location should allow for easy maintenance and serviceability. Follow the manufacturer’s guidelines regarding clearance requirements and proximity to other equipment.

By following these precautions, you can ensure a safe and effective installation of a fire pump system. Proper installation is critical for the system’s performance, compliance with regulations, and the overall safety of the facility and its occupants. Consult with fire protection professionals and refer to relevant codes and standards throughout the installation process.
