Fire pumps are more expensive than ordinary water pumps because they must meet specific fire protection standards and are built to handle high temperature and pressure water. They also have additional features, such as larger motors, to rapidly provide the necessary flow rate to meet fire protection requirements.

A horizontal fire pump has its shaft aligned horizontally, making it suitable for installations with more floor space. A vertical fire pump, on the other hand, has a vertical shaft and is ideal for spaces with limited floor area but sufficient vertical space. The choice between horizontal and vertical configurations depends on the available space, system layout, and design preferences.

Fire pump sets are often required when the local water system cannot provide sufficient pressure to meet the design hydraulic requirements of the fire sprinkler system. This typically occurs in multi-story buildings or systems that require relatively high terminal pressures at fire sprinklers in order to release large volumes of water, such as storage warehouses. A fire pump is also required if the water supply is provided from above-ground or underground storage tanks.

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 fire pump set is not installed with water inlet pipe according to customer requirements. The fire pump adopts ISW pump, which has the advantages of convenient installation and simple maintenance.The pump set consists of electric pump, diesel engine pump and jockey pump.The three pumps automatically start and stop, and they can run even if the power is cut off, without being affected by the mains.

Diesel engine fire pump is a kind of mechanical and electrical integration equipment that is directly driven by diesel engine fire pump and can start and complete water supply in a short period of time. Diesel engine pumps are driven by diesel and do not need an external power supply. Diesel engine water pumps are suitable for various fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, textiles, etc., especially where there is no electricity, When the power grid is not satisfactory, it is the safest choice to use a diesel engine to drive the water pump.
