Performance features
1. Empower your operations with three exceptional starting functions:
(1). Manual start function: Seamlessly initiate operations via a manual-automatic interlock enabled by the switch;
(2). Automatic-manual functions: Experience the assurance of three starting attempts. If unsuccessful, a 'starter failure alarm' is initiated, exiting the starting sequence. Upon a successful first start, the time to rated load initiation is adjustable within 5-10-15 seconds, tailored to unit capacity;
(3). Emergency manual direct start function: In critical moments, utilize the manual direct start function when the self-controlled device is not operational.
2. Intelligent Autonomy: Upon receiving a valid fire signal, the diesel fire pump autonomously activates. Should the electric pump falter due to power supply issues, the system seamlessly transitions to the diesel pump, resuming normal function upon power restoration.
3. Automated Safety: The diesel fire-fighting pump intuitively delays and executes an automatic shutdown as the fire signal ceases.
4. Reliable Battery Self-Charge: The battery is automatically energized via the mains power of the diesel engine, guaranteeing a smooth initiation of the unit.
5. Comprehensive Indicating System: Be informed with indicators for readiness, manual/automatic start, operational status, shutdown, battery charging, overspeed alerts, lubricant and turbocharger oil pressures, engine lubricating oil temperature, cooling system water temperature, battery voltage, fuel level, and regular inspection alerts.
6. Robust Alarm and Protection System: Safeguard operations with alerts for failed starts, overspeed, lubricant oil pressure, turbocharger oil pressure, cooling water temperature, lubricating oil temperature, automatic charging device issues, battery voltage levels, and fuel levels.
7. Advanced Display Systems: Monitor essential metrics such as engine oil pressure, engine speed, battery charge current, and battery charging voltage.
8. Direct-coupled Efficiency: The diesel engine and water pump are united by a high-flexible coupling on a shared channel base, offering a compact structure, superior performance, reduced failures, minimal vibration, and easy on-site installation.
9. Exceptional Pressure and Flow Capacity: With options from the IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps, our solutions cater to diverse fire-fighting scenarios.
10. Adaptive Flow and Pressure: Equipped with mechanical or electronic speed governors, our diesel pumps allow speed adjustments to align pump flow and head with actual data requirements.
11. Pre-heating Device for Optimal Performance: An AC220V cooling water preheating device guarantees seamless operation in environments below 5 ºC.
12. Dual Battery Circuit Assurance: In the event of a battery group failure, the system automatically engages an alternative group, ensuring uninterrupted operation.
13. Maintenance-Free Battery Convenience: Enjoy the freedom from frequent supplemental fluid additions with our maintenance-free battery.
14. Automatic Timing Inspection Test: Our cutting-edge fire system, typically in a vigilant standby mode, is designed to autonomously conduct comprehensive device testing. It ensures impeccable standby conditions and promptly issues timely warnings to guarantee optimal safety and reliability.
Note: Tailor your experience with us! The aforementioned functions are adaptable and can be handpicked based on user preferences. Moreover, our expertise extends to crafting bespoke designs meticulously aligned with your specific requirements, ensuring a perfect fit for your unique needs.
