Introduction to CB10/100 fire pump

In the field of firefighting, the fire pump, as a core component of fire trucks, directly impacts the efficiency and effectiveness of fire extinguishment. Among them, the CB10/100 low-pressure vehicle fire pump has gained widespread recognition and application due to its excellent performance and reliability.

I. Introduction to the CB10/100 Fire Pump

The CB10/100-XZ low-pressure vehicle fire pump adopts a double-stage vane centrifugal structure, exhibiting outstanding pump performance. Its impeller can be made of stainless steel or brass, ensuring the durability and stability of the pump body.

Additionally, this fire pump features low rotational speed, stable operation, and reliable quality. The priming system employs an electric four-piston device, coupled with a check valve, to ensure reliable operation of the fire pump in complex environments.

The following table presents the operating performance parameters of the CB10/100-XZ fire pump under different models, including flow rate, outlet pressure, rated speed, shaft power, and suction depth. These data provide important references for users to select and configure fire pumps according to different needs.

II. Structure of the CB10/100 Fire Pump

The CB10/100 fire pump primarily consists of the following components:

1. Four-Piston Primer: It introduces liquid into the pump through the reciprocating motion of four pistons, serving as a key component in the priming process of the fire pump.

2. Check Valve: It ensures one-way flow of the liquid, preventing backflow and ensuring normal operation of the pump.

3. Speed Measuring Gear: It monitors the pump's rotational speed in real-time, providing accurate data support for operators to ensure the pump operates within an efficient working range.

4. Pump Body: It is the main part of the double-stage vane centrifugal structure where the impeller rotates to generate centrifugal force, delivering the liquid at high pressure.

5. Gearbox: It transmits power to the input shaft, driving the impeller to rotate, and maintains stable temperature through circulating cooling water in the cooling pipes.

6. Cooling Pipes: They ensure that the gearbox and bearings do not overheat during operation, enhancing the pump's service life.

7. Input Shaft: It connects the motor and gearbox, transmitting power to the pump body to drive the impeller rotation.
These components are meticulously designed and precision-manufactured, ensuring the overall performance and durability of the CB10/100 fire pump.

III. Working Principle of the CB10/100 Fire Pump

The working principle of the CB10/100 fire pump primarily includes four parts: the priming process, liquid delivery, cooling mechanism, and speed monitoring.

1. Priming Process: When the fire pump starts, the four-piston primer begins to work, introducing liquid into the pump through the reciprocating motion of the four pistons. The check valve ensures one-way flow of the liquid, preventing backflow. This process is quick and efficient, saving valuable time for subsequent firefighting efforts.

2. Liquid Delivery: The liquid introduced into the pump is accelerated and ejected through the double-stage vane centrifugal structure under the action of the impeller, forming high-pressure water flow. This process enables the fire pump to rapidly deliver water or foam extinguishing agents to the fire source, effectively extinguishing the fire.

3. Cooling Mechanism: During the operation of the fire pump, the gearbox and bearings generate a significant amount of heat. To maintain stable temperatures and prevent overheating, circulating cooling water in the cooling pipes continuously flows to dissipate the generated heat, ensuring normal operation of the pump.

4. Speed Monitoring: The speed measuring gear monitors the pump's rotational speed in real-time and transmits data to the control system. Operators can adjust the pump's working state based on these data to ensure it always operates within an efficient working range.

IV. Maintenance Suggestions for the CB10/100 Fire Pump

To ensure the high efficiency and long service life of the CB10/100 fire pump, here are some key maintenance suggestions:

1. Regular Inspection and Maintenance:

o Regularly inspect the four-piston primer, and replace worn parts promptly to ensure smooth priming.
o Check the seal of the check valve to ensure it is good, preventing liquid backflow that could affect the normal operation of the pump.
o Inspect the impeller and vanes for wear and corrosion, and replace them if necessary to maintain the pump's high efficiency.

2. Cooling System Maintenance:

o Regularly clean scale and impurities from the cooling pipes to ensure smooth cooling water flow and prevent overheating issues caused by blockages.
o Check the lubrication of the gearbox and bearings, and regularly add or replace lubricating oil to reduce wear and extend service life.

3. Seal Inspection:

o Regularly inspect the seals throughout the pump body to ensure there is no leakage, preventing performance degradation or safety hazards caused by leakage.
o Regularly replace the seals of the input shaft to prevent dust and impurities from entering the pump and affecting its normal operation.

4. Speed Monitoring and Motor Inspection:
o Regularly check the working status of the speed measuring gear to ensure it accurately monitors the pump speed and provides accurate data support for operators.
o Inspect the operating status of the drive motor to ensure normal interaction between the motor and the pump, preventing the pump from malfunctioning due to motor failures.

5. Anti-Corrosion Treatment and Storage:

o Select appropriate impeller materials based on the operating environment, and apply anti-corrosion coatings if necessary to improve the pump's corrosion resistance.
o When storing the fire pump, choose a dry, well-ventilated place to prevent performance degradation caused by moisture or corrosion.

By following these maintenance suggestions, the CB10/100 fire pump can maintain high efficiency and reliable performance in emergencies, providing strong support for firefighting efforts.
