Performance features
1, With 3 types of perfect starting-functions:
(1). Manual start function: Achieve manual start through a seamless manual-automatic interlocking switch;
(2). Automatic-manual functions: Designed to allow three start attempts, initiating a "starter failure alarm" and automatically discontinuing the starting process if unsuccessful after three tries. The transition to the rated load occurs within 5-10-15 seconds, depending on unit capacity, upon a successful first start.
(3). Emergency manual direct start function: In emergencies, achieve a manual direct start when automatic systems face malfunctions.
2. Automatic operation: Upon receiving a valid fire signal, the diesel fire pump automatically initiates if the pump cannot start due to interruptions or failures in the fire pump motor's power supply. It switches back to electric operation once the system normalizes.
3. Automatic shutdown: The diesel fire-fighting pump intelligently delays and ceases operation automatically when the fire signal subsides.
4. The battery self-charge function: Ensure seamless unit startup with automated battery charging via the diesel engine's electrical mains power.
5. Perfect indicating system: Comprehensive indicators for readiness including manual start, automatic start, operation status, shutdown, battery charging, and alerts for speeding, low oil pressure, and more, providing constant updates and insights.
6. Perfect alarm or protection system: Advanced alarms and protective measures address start failures, overspeed conditions, low lubricant pressure, high cooling water temperature, battery charge issues, and low fuel levels.
7. Perfect display systems: Real-time updates on engine oil pressure, RPM, battery charge current, and voltage ensure optimal monitoring and maintenance.
8. Direct-coupled: The diesel engine and water pump are joined by a high-flexibility coupling on a common base, offering a compact, efficient structure with reduced failure rates and minimal vibration, simplifying on-site construction and installation.
9. With high pressure and big flow capacity: Options including IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps are available to suit diverse fire-fighting scenarios.
10. Be adjustable of flow and working pressure: Diesel pumps with mechanical or electronic speed governors allow for speed adjustments, aligning pump flow and pressure with actual requirements, ensuring precision and efficiency.
11. With pre-heating device of water temperature: Equipped with an AC220V water preheating system, ensuring optimal performance even in environments below 5 ºC.
12. Double battery circuit: Should one battery group fail, the system automatically switches to an alternative, maintaining continuous operation.
13. Maintenance-free battery: Designed for convenience, these batteries eliminate the need for frequent fluid top-ups, ensuring hassle-free operation.
14. Automatic timing inspection test: The fire system, typically in a standby mode, boasts an advanced capability to autonomously conduct device testing for standby conditions. It ensures timely warnings, safeguarding continuous operational readiness.
Note: The above functions can be tailored to meet user-specific requirements. Our expertise extends to delivering custom-designed solutions that precisely align with your unique specifications.
