EJ Electric Fire Pump Set

A fire pump is a critical component of a fire sprinkler system, providing the necessary water pressure to ensure the sprinkler system works properly. Fire pumps are usually powered by electric motors or diesel engines and they come in centrifugal, turbine, or rotary types.

To ensure that the fire pump is working properly, it is important to maintain and test it regularly. Regular maintenance tasks include inspecting the motor and fuel system, changing the oil, and checking the battery. Testing the pump pressure and flow rate should also be done on a regular basis. If any issues are found, it is important to contact a professional for assistance. A trained technician should also inspect the fire pump annually.

Fire pump components:
1. Diesel pump: the flow rate is the same as that of the electric pump. It connects pump sets with highly elastic couplings or universal joints.
2. Pipeline supplementary pressure pump: vertical, small flow, higher lift than electric or diesel pumps.
3. Control panel: Automatically control the water pump with overload and overcurrent protection.

Fire pump as the name implies, fire pump, according to different classification is divided into different kinds of it is fully sealed, no leakage, corrosion resistance, widely used in environmental protection, water treatment, fire departments, is used to pump all kinds of liquid equipment.

The current use of fire pumps is still relatively important. As the name suggests, fire pumps are pumps used for fire protection. The fire pumps we use now are all imported from abroad. Its performance mainly includes three aspects, sealing, no leakage, and corrosion resistance. Because of the particularity of its use, its requirements are relatively strict in terms of material selection and production. Considering many aspects, the performance and technical conditions of the fire pump meet the requirements of the “Fire Pump Performance and Test Methods” standard.

The standard DJ fire pump set consists of one diesel pump + one jockey pump, which is suitable for fire protection occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas, textiles, ships, and oil tankers.

Electric motor 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 water. The electric motor 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.

EDJ fire pump set consists of main electric pump (motor driven), standby diesel pump (diesel engine driven) and jockey pump. The pump is assembled from discharge and suction pipes and a control panel. The fire pump system can be customized for different uses such as high-rise buildings, warehouses, facilities, hospitals, supermarkets, shopping malls, villas, apartments, etc.

1. When the pipeline fire pump noise occurs, the most likely fault is the imbalance of the fire pump rotor. Since the water output of the fire pump mainly depends on the high-speed rotation of the rotor, when the rotor is unbalanced for some reason, it will cause the fire pump to deviate from the original rotation track during the rotation process, resulting in the fire pump appearing in the pipeline. When judging the failure of the rotor, it is mainly to replace the rotor of the pump or make a balance hole on the rotor blade of the pump to find out the balance difference.

2. The production noise of the fire pump pipeline has a certain effect. For example, forcing a small flow of a pipe “fire pump” to increase power to increase the original flow will create vibrations in the fire pump. Therefore, whether you use a pipeline fire pump or other types of water pumps, you should follow the water pump use standards to prevent the water pump from making noise, which will affect the service life of the water pump. The solution is to use the pump according to the instructions. If the efficiency of use is affected, it is recommended to replace the appropriate pipeline “fire pump” for use.

3. The installation did not meet the standards, resulting in abnormal noise from the pipeline fire pump. Fire pumps and fire hydrant pumps vibrate at a high frequency during operation, so they must be fixed during installation. If the bolt between the pump body and the base or between the base and the base is loose when installing the pipe fire pump, the transmission shaft between the pump body and the motor of the pipe pump will be bent. It lowered the concentricity and caused an imbalance in the fire pump rotor. This is one of the noise phenomena of fire pumps. In order to improve this phenomenon, the pump shaft of the fire pump needs to be balanced and then reinstalled. Finally, the base of the pump was reinforced.

4. Blockage of the impeller passage can also cause fire pump noise. When the internal flow channel of the fire pump is blocked by foreign matter, it will cause uneven resistance of the fire pump impeller and vibrate the fire pump. Therefore, it is necessary to regularly disassemble and maintain the fire pump to prevent foreign matter from blocking the pipeline.

5. The bearing of the fire pump is damaged. Bearing damage generally does not occur on the main body of an in-line fire pump. If there is a problem with the quality of the pump, or because some hard objects enter the pump body of the tube pump, the bearing is damaged, and the rotor is unstable at first. Causes noise from pipeline fire pumps.

6. Finally, cavitation, cavitation occurs in any type of pump, but some are obviously not noticeable. If cavitation occurs, consider raising the fire pump or increasing the pressure in the piping. If the cavitation phenomenon cannot be changed, the fire pump model needs to be redesigned and replaced.

The biggest difference between the diesel engine fire pump and the electric water pump is that it has its own independent power supply system – the storage battery. Therefore, the start and operation of the diesel engine fire pump can be completely separated from the mains.
