The application of electric fire pumps is not only in fire protection systems

The fire pump refers to a clean water pump used for fire water supply, and a single pump that handles medium temperature below 80 degrees and is not corrosive. The pump set is the joint operation of multiple fire pumps to ensure the quantity and stability of the water supply. The electric motor fire pump group adopts multiple fire pumps powered by electric motors. The general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption. The main components of the electric motor fire pump group are the motor and the pump body. The subdivision of the pump body is the pump casing, the impeller, the pump shaft, the bearing, the coupling, the sealing form, the lifting pipe, etc. The specific fire pump model is determined according to the environment and performance requirements. According to the material quotation required by the customer, accurate selection is beneficial to on-site use and reduces failure problems.

The fire pump set is a customized 160kw EDJ fire pump, which is composed of electric pump + diesel pump + jockey pump. It is a standard fire pump set, which is easy to install the fire pump set on site; easy to debug; Wiring electrical connections; less space requirements; all (pump, drive and controller) on one base, etc.

One way of choosing a diesel generator as a backup power source for fire protection is because in fire protection, two power supplies are required, which can be two power plants and two transformers, or one line of city power and one line of diesel generator set power supply. Meet the requirements of fire backup power.

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.

1. The fire pump packing seal should be able to form a reliable seal without leaking, and it should have good wear resistance.

2. The packing seal should have good elasticity and flexibility in order to accommodate the thermal expansion and contraction of the pump.

3. The packing seal should be able to maintain its shape and flexibility over time, and it should also be resistant to corrosion from the pump’s fluids.

4. The packing seal should be easy to install and remove, and it should be able to withstand high pressures and temperatures.

As the name implies, fire pumps are classified into different types according to different classification methods, and are widely used in environmental protection, water treatment, fire protection and other departments because of their fully sealed, leak-free, and corrosion-resistant characteristics. liquid-like. The pump types are similar, but the head and flow are different. The selection basis of the fire pump should be considered according to the process flow, water supply and drainage requirements, and other five aspects.

The double-suction fire pump has the characteristics of high lift and large flow, and is widely used in fire fighting. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

The product is EJ fire pump set. The EJ fire pump set has one electric pump and one jockey pump. The electric pump in the picture is XA pump. XA series horizontal single-stage single-suction centrifugal pump is a new generation of energy saving, environment friendly horizontal centrifugal pump researched and developed by our company, which absorbs advanced technology of similar products abroad and adopts domestic general performance parameters of centrifugal pumps.

Fire pumps are designed to operate in a range of environmental conditions, but extreme weather conditions can pose challenges. Adequate protection measures and regular maintenance help ensure that fire pumps function reliably in various weather conditions.

Diesel engine fire pumps can form an automatic fire water supply system with electric pumps and jockey pumps. See the introduction of “Diesel Engine Control System” for its working process. The equipment can realize joint control with the fire center. The fire pump unit is combined with the fire pump through the high elastic coupling. The unit also includes diesel tank, cooling water tank, fan, control panel (for automatic unit) and other components.

When it is an automatic control unit, the split diesel engine automatic control cabinet realizes the functions of automatic reset, input, automatic switching, automatic protection and other functions of the system. At the same time, it can also interface with the user’s fire center or automatic fire alarm device to realize remote control monitor.

For temporary structures and events, such as construction sites, outdoor festivals, or temporary exhibition halls, fire pumps and jockey pumps are vital for providing an adaptable and reliable fire protection solution. Portable fire pumps can be quickly deployed to deliver water to temporary sprinkler systems or standpipes, ensuring fire safety even in temporary settings. Jockey pumps help maintain pressure in these temporary systems, ensuring that they are always ready for immediate activation without requiring constant manual intervention. Given the temporary nature of these structures, fire pumps must be easy to transport, install, and operate, while also being durable enough to withstand outdoor conditions and frequent relocation. This flexibility makes them indispensable for ensuring fire safety in environments where traditional fire protection infrastructure may not be available.

The vertical multistage centrifugal pump set cooperates with the main pump to take water from the pool and transport it to the system to maintain the system pressure.
The pressure stabilizer pump of the “stabilized high pressure” fire water supply system must be kept in operation at ordinary times to maintain the pressure of the pipe network. In the event of a fire, it should still be able to run for a period of time until the main fire pump is started. Set up the booster pump. Because the constant pressure pump needs to keep running all the time, which wastes energy, and the constant pressure pump is in working state for a long time, it has high requirements on its service life, so this method is no longer used in the project.

These pumps ensure that a building’s fire protection system operates effectively during an emergency, providing the necessary water pressure and flow to control or extinguish fires, thereby protecting lives and property.
