Performance Features
1. Equipped with Three Sophisticated Starting Functions:
(1). Manual Start Function: Achieve seamless manual-start functionality with a manual-automatic interlock switch, ensuring ease of use and reliability.
(2). Automatic-Manual Functionality: Offers the convenience of three starting attempts. If unsuccessful, it triggers a 'starter failure alarm' and exits the starting state. Post-successful startup, the transition to rated load occurs within 5-10-15 seconds, based on unit capacity size.
(3). Emergency Manual Direct Start: Effortlessly achieve a direct start in emergencies, even when self-controlled devices experience failures.
2. Seamless Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump automatically initiates operation if the fire pump motor's power supply is interrupted or experiences phase failure. Once the power supply normalizes or electric pumps function properly, it switches back to electric pump operation effortlessly.
3. Automatic Shutdown: The diesel fire-fighting pump gracefully delays and shuts down automatically when the fire signal ceases, ensuring safety and efficiency.
4. Self-Charging Battery Functionality: The battery is automatically charged via the diesel engine's electrical mains power, guaranteeing a smooth and reliable start-up of the unit.
5. Comprehensive Indicating System: Ready indicators cover manual start, automatic start, unit operation, shutdown, battery charging, speeding, low lubrication oil pressure, low turbocharger oil pressure, low engine lubricating oil temperature, high cooling system water temperature, battery low voltage, low fuel level, and regular inspections.
6. Advanced Alarm and Protection System: Features alerts for three-time start failures, overspeed, low lubricant oil pressure, low turbocharger oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device failures, low and high battery voltage, and low fuel levels.
7. Superior Display Systems: Monitor vital metrics such as engine oil pressure, engine speed, battery charge current, and battery charging voltage with precision.
8. Direct-Coupled Excellence: The diesel engine and water pump are seamlessly integrated via high-flexible coupling on a common channel base, providing a compact structure with exceptional overall performance, minimal failure rates, reduced vibration, and convenient on-site installation.
9. High Pressure and Significant Flow Capacity: Choose from IS series single-stage single-suction, SOW series single-stage double-suction pump, or SHD series segmental multistage pumps to meet diverse fire scenario demands.
10. Adjustable Flow and Working Pressure: Diesel pumps, equipped with mechanical or electronic speed governors, allow you to adjust the diesel engine's speed to align the pump's flow and head with actual data.
11. Water Temperature Pre-Heating Device: The unit is equipped with an AC220V cooling water pre-heating device, ensuring optimal operation even in environments below 5 ºC.
12. Dual Battery Circuit: In case of a battery group failure, an alternate one automatically takes over, ensuring operational continuity.
13. Maintenance-Free Battery: Enjoy the convenience of a battery that requires no frequent supplemental fluid, ensuring uninterrupted performance.
14. Automatic Timing Inspection Test: Experience seamless safety and reliability with our advanced fire system, which remains in standby mode while intelligently performing automatic device tests. This ensures the system is always primed for action, providing timely alerts and peace of mind.
