Performance features
1. Includes three impeccable starting functions:
(1). Manual start function: Achieve manual-start seamlessly through a manual-automatic interlocking switch;
(2). Automatic-manual functions: Allows three starting attempts, issuing a 'starter failure alarm' and automatically ceasing attempts after three failed starts. The rated load begins within 5-10-15 seconds post-successful start, depending on unit capacity;
(3). Emergency manual direct start: Provides a manual direct start option in emergencies when self-controlled devices fail.
2. Automatic operation: Upon receiving a fire signal, the diesel fire pump automatically initiates, ensuring operation even if the electric pump is compromised due to power interruptions. It seamlessly transitions back to the electric pump once the power supply stabilizes.
3. Automatic shutdown: The diesel fire-fighting pump will delay and shut down automatically once the fire signal ceases.
4. Battery self-charge function: The battery charges automatically via the diesel engine's electrical mains power, ensuring reliable startup.
5. Comprehensive indicating system: Provides real-time status including readiness, manual start, automatic start, operation, shutdown, battery charging, low oil pressures, high water temperatures, low fuel levels, and regular inspection indicators.
6. Robust alarm or protection system: Features alarms for three failed start attempts, overspeed, low lubricant pressure, high water temperature, charging issues, and fuel level alerts, ensuring operational safety.
7. Advanced display systems: Monitors engine oil pressure, speed, battery charge current, and voltage for optimal performance tracking.
8. Direct-coupled design: The diesel engine and water pump are unified by a high-flexible coupling on a shared channel base, ensuring a compact structure with superior performance, reduced vibration, and straightforward on-site installation.
9. Offers high pressure and large flow capacity: Available with IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps, these units address diverse fire scenarios.
10. Adjustable flow and pressure: Diesel pumps equipped with mechanical or electronic governors allow speed adjustments to align pump flow and head with actual requirements.
11. Pre-heating device: Equipped with an AC220V cooling water preheater, ensuring normal operation even in environments below 5 ºC.
12. Dual battery circuit: In case of one battery's failure, the alternate battery seamlessly activates.
13. Maintenance-free battery: Eliminates the frequent need for supplemental fluid, enhancing convenience.
14. Automatic Timing Inspection Test: Ensuring safety and efficiency, our fire system remains in standby mode, while the unit seamlessly performs device testing to confirm standby conditions. It promptly issues timely warnings to maintain optimal functionality.
Note: Tailor your experience with us! The above functions are selectable based on your unique requirements. Additionally, we offer bespoke design solutions to meet your specific needs.
