1. Hydraulic system specifically designed for high-head applications
This pump set adopts a multi-stage high-pressure centrifugal pump structure, capable of providing a rated head exceeding 180 meters and a maximum output pressure of over 2.0 MPa. This design effectively addresses the issue of insufficient water pressure at the rooftop or upper floors of high-rise buildings, a common challenge with traditional fire pumps. Each impeller stage undergoes dynamic balancing calibration to ensure minimal vibration and high wear resistance during high-speed operation, making it particularly suitable for scenarios with extremely high pressure requirements. Additionally, the pump body is constructed from ductile iron or 304 stainless steel, offering excellent corrosion resistance and strength, and is designed for long-term continuous operation.
2. Efficient diesel power system, reliable power supply
This system is equipped with a four-stroke diesel engine compliant with European and American environmental standards, utilizing electronic fuel injection technology and a turbocharging system, offering high combustion efficiency and strong instantaneous torque output. Even in environments without grid power or with unstable emergency power supply, the system can operate autonomously. The engine power ranges from 85 kW to 350 kW, allowing flexible configuration based on building height and requirements. The fuel tank supports 8 hours of continuous operation, making it an ideal backup solution during municipal power outages.
3. Intelligent variable operating condition control logic
The system is equipped with an intelligent variable operating condition controller that can real-time monitor pressure, flow rate, and operational load within the water supply system. It dynamically adjusts engine speed and pump output power based on pre-set parameters to achieve on-demand water supply. Through PID precise regulation technology, the system can control output pressure error within ±0.03 MPa, ensuring constant pressure water supply while reducing energy waste and equipment wear.
4. Automatic Start-Stop + Emergency Switching Dual Modules
Once the system detects that the pipeline pressure has fallen below the set threshold, the automatic start-stop module will immediately start the diesel engine and drive the pump to ensure immediate fire water supply. If the main pump malfunctions, the system will automatically switch to the backup pump or manual intervention mode to prevent water supply interruption. Additionally, the system supports remote manual start and stop operations and can seamlessly integrate with fire control rooms or BMS systems.
5. Compact Structure, Space-Saving Design
The entire pump set adopts an integrated skid-mounted base design, occupying approximately 60% of the floor space of traditional systems. It is particularly suitable for underground pump rooms, equipment wells, or high-rise buildings with limited mechanical space. The base is equipped with anti-vibration rubber pads and lifting holes for convenient transportation, installation, and maintenance.
6. Modular maintenance design reduces long-term operational costs
The core components of the pump set are arranged in a modular layout, including the diesel engine, pump, transmission system, control panel, and cooling system. During maintenance, only the corresponding module needs to be disassembled, significantly reducing downtime for maintenance. Additionally, the control system supports historical data logging and fault warning functions, facilitating routine inspections and fault tracing, thereby reducing the risk of unplanned downtime.
7. Quiet exhaust and noise reduction devices
Considering the high noise control requirements of high-rise buildings, the system is equipped with industrial-grade quiet exhaust pipes, noise reduction partitions, and anti-vibration bases to effectively control operating noise to no more than 85 dB(A). This configuration is particularly suitable for noise-sensitive areas such as residential buildings, hotels, hospitals, and office buildings.
8. Highly Adaptive Cooling System
The system employs a dual-channel radiator system and intelligent fan control mechanism, ensuring engine coolant temperature remains within safe limits even during summer heatwaves or in enclosed underground spaces. Fan speed automatically adjusts based on coolant temperature, reducing energy consumption while enhancing cooling efficiency and preventing engine shutdown due to overheating.
9. International Standard Certification Assurance
This pump unit complies with CCC, ISO, and NFPA20 standards, making it suitable for global construction projects. Clients can select certified versions according to local project requirements to meet domestic and international fire safety inspection standards, with customization services available.
10. Smart Networking Functionality Supports Smart Fire Protection
The system supports 4G/5G remote monitoring and integration with IoT cloud platforms. Operational data can be uploaded to the cloud in real time, allowing maintenance personnel to view pump set status, historical records, and alarm information in real time via a mobile app or central control platform, providing data support for smart fire protection management systems.
The high-head variable-condition adaptive diesel pump set is an advanced fire protection power solution tailored for modern high-rise buildings. It offers significant advantages in high-head water supply, variable-condition response, system stability, and intelligent control, ensuring continuous and reliable water supply even in complex and demanding environments. For users seeking high-standard, high-reliability fire protection systems, this pump set is not only a guarantee of efficiency and safety but also a crucial step toward future smart fire protection solutions.
