1. Ability to provide a steady and reliable flow of water: Fire pumps are designed to provide a steady and reliable flow of water to the fire suppression system. This ensures that the fire is extinguished quickly and without any damage to the property.

2. High-Pressure Output: Fire pumps can provide a high-pressure output to ensure that the water is able to reach further distances and at higher pressures than would be achievable by a standard water system. This is important in controlling and extinguishing fires, as it allows the water to reach all areas of the fire.

3. Emergency Operation: Fire pumps are designed to be able to operate in the event of a power outage. This ensures that the fire suppression system can still be operational in the event of a power failure. This is especially important in commercial buildings and other areas where power outages can occur.

4. Automatic Activation: Fire pumps are designed to automatically activate in the event of a fire. This ensures that the fire suppression system can be activated quickly and without any manual intervention. This is especially important in the event of a large fire, as it ensures that the system is already in operation before the fire department arrives.

5. Low Maintenance: Fire pumps are designed to be low maintenance, requiring only regular inspections and maintenance to ensure that they are working correctly. This ensures that the fire suppression system is always ready for use and that it can be relied upon in the event of a fire.

The pressure switch and the control cabinet can automatically turn on/off the three pumps, the electric pump and the pipeline pressure pump work when there is electricity, and the diesel pump is started when the power is off.

There are several types of fire pumps, each designed for specific applications. Two common categories are centrifugal and positive displacement pumps.

Centrifugal pumps are widely used in fire protection systems due to their simplicity and reliability. They work by imparting kinetic energy to the water, which then exits the pump under pressure. These pumps are well-suited for maintaining consistent water pressure for fire suppression.

Positive displacement pumps, on the other hand, use a different mechanism. They trap water in a chamber and then force it into the discharge piping, creating pressure. Positive displacement pumps are typically used in situations where high pressure or low flow is required.

The choice of pump depends on the specific needs of the fire protection system and the facility it serves.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. When the joceky pump detects that the electric pump cannot operate normally, the diesel engine pump will start automatically. Can also be used, the fire pump set is widely used in various emergency firefighting occasions

Fire pumps and jockey pumps work together to ensure that a fire protection system is always ready to operate at peak efficiency. The jockey pump is primarily responsible for maintaining the system’s normal pressure, compensating for minor leaks, and preventing the fire pump from running unnecessarily. When a fire occurs, and a significant drop in pressure is detected due to water discharge from sprinklers or hoses, the fire pump is activated to provide the necessary water flow and pressure. This interaction ensures that the system operates efficiently, minimizing wear and tear on the fire pump while keeping the system primed and ready for an emergency.

Electric fire pumps are used in various water environments, not only to meet the general water supply but also to be a good helper for fire-fighting water. The electric fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The motor fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

Diesel engine fire pumps are relatively common in life, and their performance requirements are relatively high. In normal use, more attention must be paid to maintenance to prolong the service life of the pump. Because diesel fire pumps are not omnipotent, there will be some problems in daily use, so when choosing equipment, we must pay attention to whether the quality of the equipment has reached the national standard. As fire equipment, all kinds of equipment must be Ensure performance, avoid affecting use in disasters, and delay rescue.

The diesel engine (can be equipped with a clutch) is combined with the fire pump through a highly elastic coupling to form a fire pump unit. The unit also includes diesel tanks, cooling water tanks, fans, control panels (for automatic units) and other components.
When the unit is automatically controlled, the split or diesel engine automatic control cabinet (programmable) realizes the automatic start, input, and automatic switching of the system (switching from the electric pump group to the diesel engine pump group or from this group of diesel engine pump groups to another group of diesel engines) pump set), automatic protection (diesel engine overspeed, low oil pressure, high water temperature, three start failures, low oil level, low battery voltage and other alarm shutdown protection) and other functions, and can also interface with the user’s fire center or automatic fire alarm device, Realize remote monitoring.

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the voltage stabilizer pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

Yes, firefighting pumps are often used in conjunction with other fire suppression methods, such as fire extinguishers, fire sprinkler systems, and fire blankets, to provide comprehensive fire protection in various environments.

With the continuous development of society, people have higher requirements for the quality of life, and the safety of diesel engine fire pumps is more important. All places need to be equipped with fire-fighting facilities, and fire pumps are water intake equipment for fire-fighting facilities. The fire pumps we commonly use are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps need power system supply. In case of power failure, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.
