Performance Features:
1. Impeccable Starting Functions in Three Modes:
(1). Manual Start: Seamlessly engage the manual-start function through a manual-automatic interlock via the switch;
(2). Automatic-Manual Functions: With the flexibility of three starting attempts, it triggers a 'starter failure alarm' and automatically exits the starting state if unsuccessful after three attempts. The rated load start time spans 5-10-15 seconds, dependent on unit capacity, after the initial successful start;
(3). Emergency Manual Direct Start: Achieve direct manual start in emergencies when the self-controlled device encounters failures.
2. Automated Operation: Upon receiving a valid fire signal, the diesel fire pump springs into action automatically if the electric pump cannot commence due to power supply system interruption or failure. Once the system stabilizes or electric pumps can function, it transitions back to the electric pump seamlessly.
3. Automatic Shutdown: The diesel fire-fighting pump cleverly delays and auto-shuts when the fire signal ceases.
4. Self-Charging Battery Functionality: The battery autonomously charges via the electrical mains of the diesel engine, ensuring a reliable start.
5. Comprehensive Indicating System: Be informed with indicators for ready-to-start, manual, automatic starts, operation, shutdowns, battery charging, overspeed alerts, lubricating oil low pressure, turbocharger oil pressure alerts, high coolant temperatures, low battery voltage, and fuel levels, alongside regular inspections.
6. Advanced Alarm and Protection System: Receive alarms or protection for triple start failures, overspeed, low lubrication oil pressure, turbocharger oil pressure alerts, high coolant temperatures, lubricating oil temperature warnings, automatic charging device failures, battery voltage irregularities, and low fuel levels.
7. Superior Display Systems: Monitor vital statistics like engine oil pressure, engine speed, battery charge current, and charging voltage seamlessly.
8. Direct-Coupled Efficiency: Seamlessly connect the diesel engine and water pump with a high-flexible coupling on a common channel base for a compact structure, superior performance, reduced failures, and minimal vibration, facilitating hassle-free on-site installation.
9. High Pressure, Large Flow Capacity: Tailor to fire control needs with IS series single-stage single-suction, SOW series single-stage double-suction, or SHD series segmental multi-stage pumps, ensuring optimal performance for diverse fire scenarios.
10. Adjustable Flow and Pressure: Achieve precise tuning of flow and working pressures via mechanical or electronic speed governors, modifying engine speed to match the actual pump data.
11. Pre-Heating Water Temperature Device: Equipped with an AC220V cooling water preheating device, this unit guarantees smooth operation even below 5 ºC, ensuring reliability in all climates.
12. Dual Battery Circuit: In the event of one battery's failure, the alternate battery effortlessly takes over, ensuring uninterrupted functionality.
13. Maintenance-Free Battery: Enjoy the convenience of a battery that requires no frequent supplemental fluid additions.
14. Automatic Timing Inspection Test: Our advanced fire system is designed to seamlessly perform in standby mode. It is equipped to autonomously conduct necessary device tests under standby conditions, ensuring readiness and safety by delivering timely warnings when required.
Note: The aforementioned functions are customizable to meet diverse user requirements. Additionally, we offer bespoke design solutions to cater to your unique specifications, ensuring that every need is meticulously addressed.
