EDJ series fire pump sets are mainly installed in fire trucks, fire extinguishing systems or other fire fighting facilities, and are special pumps used to transport liquids such as water or foam solution.
The fire pump set includes a main pump connected to the electric motor, a backup pump connected to the diesel engine, jockey pump, pressure vessel, controller for manual or automatic operation of the system and standard accessories mounted on the base.

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.

With advanced automation, remote monitoring, and energy-saving features, the EJ Dual Power Fire Pump System is a trusted choice for commercial, industrial, and residential applications.

When installing fire pumps and jockey pumps, environmental considerations are increasingly important to minimize ecological impact and comply with regulatory standards. This includes choosing energy-efficient models that reduce power consumption and greenhouse gas emissions, which can be particularly significant for systems that operate continuously or frequently. Additionally, it is important to consider the water source for fire pumps, ensuring that they do not deplete local water supplies or adversely affect nearby ecosystems. Using sustainable materials and manufacturing processes for pump components can also reduce environmental footprints. In some cases, fire pump systems can be integrated with rainwater harvesting or greywater recycling systems to utilize alternative water sources, further minimizing environmental impact.

Diesel engine fire pump is also called “engineering diesel engine fire pump set”. The diesel engine fire pump set has the characteristics of good starting characteristics, strong overload capacity, compact and reasonable structure, convenient maintenance, simple and reliable use, etc. The unit is equipped with protection functions such as overspeed, low oil pressure, three start failures, high water temperature, low oil level, and low battery voltage.

The dual power fire pump is composed of a fire water pump, a double shaft extension motor and a diesel engine. One end of the output shaft of the double shaft extension motor is connected to the input shaft of the fire pump, and the other end of the output shaft of the double shaft extension motor is One end of a clutch is connected, and the other end of the clutch is connected with the output shaft of the diesel engine. The fire water pump, the double-shaft extension motor, the clutch and the diesel engine are all fixed on the base. The double shaft extension motor, the clutch and the diesel engine are respectively electrically connected with a control circuit through an action drive circuit. With dual-power fire pumps, there is no need to configure a second fire pump, which reduces floor space and saves manufacturing costs.

Fire pumps work by drawing water from a water source (such as a storage tank or a dedicated water supply) and then increasing the pressure to deliver water through the fire sprinkler system or hoses. They are typically powered by electric motors or diesel engines.
