How to use the electric fire pump set reasonably?

Fire pump kits include a combination of electric pumps, diesel engine driven and electric motor driven jockey pumps for use in fire suppression systems. The fire pump group has a large flow rate, plays an important role in fire, and maintains a long-term high-efficiency working state under the condition of continuous water resources. With good reliability, it is welcomed and accepted by customers all over the world.

Fire pumps are mainly used for pressurized water delivery in firefighting system pipelines, and can also be used in industrial and urban water supply and drainage, high-rise building depressurized water delivery, long-distance water delivery, heating, bathrooms, boiler cold and warm water circulation pressurized air conditioning refrigeration system water delivery and equipment matching, etc.

The diesel engine fire pump has the characteristics of good starting performance, serious load operation, compact structure, time-saving and labor-saving maintenance, simple application, and high level of automatic control technology. It is a security monitoring device with reliable performance.

Three start-up functions for diesel engines:
1. Manual start function: manual and automatic interlocking can be completed through the transfer switch, and the manual start function can be realized:

2. Automatic manual function: allow to start three times. If the startup fails for three times, it will issue a “startup failure alarm” and automatically exit the startup state. After a successful startup, the time from startup to rated load is 5-10-15S (depending on the unit capacity);

3. Emergency manual direct start function: When the automatic control device fails, the emergency manual direct start function can be realized.

1. The performance of the fire pump should meet the flow and pressure requirements of the fire water supply system.
2. The power of the driver equipped with the fire pump should meet the requirements of the power required for operation at any point on the performance curve of the selected pump’s flow and lift.
3. When a motor-driven fire pump is used, a dry-installed fire pump with the motor should be selected.
4. The fire pump should be installed dry, and the pump should be placed outside the pool, and the submersible pump cannot be directly placed in the water for water absorption.

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.

Due to its stable performance and high frequency of use, diesel engine fire pumps can be matched with various domestic and foreign brands of diesel engines according to user needs, and can be selected according to the required head, flow, power and fire pump material requirements to ensure stable use by customers. Diesel engine fire pumps operate automatically It is simple, adopts good hydraulic design and structural design, and has high operating efficiency. It is very suitable for applications in warehouses, docks, power plants, textiles and other enterprises.

The electric fire pump set is an important fire pump equipment, usually in a horizontal state. Each pump group is composed of five parts: front pump, electric motor, hydraulic coupling, main feed water pump, lubricating oil device (including lubricating oil cooler and working oil cooler. In normal state, two sets are running, one There are two standby pumps, and any feedwater pump set can be used as a standby pump. When one of the two running pumps stops due to an accident, the standby pump will be put into operation automatically.

XBC diesel engine fire pump set is in accordance with the standard GB6245-2006 “Fire Pump Performance Requirements and Test Methods”. This series of products has a wide range of head and flow, which can fully meet the fire water supply in various occasions of industrial and mining enterprises such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas stations, and textiles. The advantage is that the electric fire pump cannot be started after the power system of the building suddenly loses power, and the diesel engine fire pump is automatically started and put into emergency water supply.

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.
