Performance Features
1. Three Exceptional Starting Functions:
(1). Manual Start Function: Experience seamless manual-start capability, elegantly achieved with a manual-automatic interlock via a switch.
(2). Automatic-Manual Functions: Enjoy the flexibility of three starting attempts, coupled with a smart "starter failure alarm" to gracefully exit if unsuccessful. Post a successful start, transition to rated load in a swift 5-10-15 seconds, dependent on unit capacity.
(3). Emergency Manual Direct Start Function: Harness the power of immediate manual start during emergencies, effortlessly overcoming self-controlled device failures.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump springs into action. In instances where the power supply system falters, the pump initiates smoothly. Once power is restored, it astutely switches back to the electric pump, ensuring reliable performance.
3. Automatic Shutdown: As the fire signal dissipates, the diesel fire-fighting pump gracefully delays and then automatically powers down, maintaining peace of mind.
4. Self-Charging Battery Function: The battery enjoys seamless charging via the electrical mains power of the diesel engine, guaranteeing a flawless start of the unit.
5. Superior Indicating System: From readiness to start, manual start, automatic start, unit operation, shutdown, battery charging, to alerts on speeding, low oil pressure, and various other parameters, our system provides comprehensive monitoring for unparalleled oversight.
6. Robust Alarm and Protection System: With alarms for failed start attempts, overspeed, low lubricant pressure, and challenges in cooling, among others, our system ensures robust protection and operational integrity.
7. Advanced Display Systems: Keep an eye on engine oil pressure, engine speed, battery charge current, and charging voltage, all at a glance.
8. Direct-Coupled Design: Featuring a high-flexible coupling between the diesel engine and water pump, mounted on a common channel base, this design ensures compactness, excellent performance, minimal failure, and easy onsite installation.
9. High Pressure and Large Flow Capacity: Choose from IS series single-stage single-suction, SOW series single-stage double-suction, or SHD series segmental multistage pumps to address a myriad of fire scenarios with confidence.
10. Adjustable Flow and Working Pressure: With mechanical or electronic speed governors, our diesel pumps adapt seamlessly to varying flow and head requirements, ensuring alignment with actual data.
11. Pre-Heating Device for Water Temperature: Equipped with an AC220V cooling water preheating device, our unit promises reliable operation even in environments below 5 ºC.
12. Double Battery Circuit: In case of a battery failure, a secondary battery circuit automatically takes over, ensuring uninterrupted performance.
13. Maintenance-Free Battery: Enjoy the convenience of a battery that requires no frequent supplemental fluid, epitomizing hassle-free maintenance.
14. Automatic Timing Inspection Test: In scenarios where the fire system predominantly remains in standby mode, our advanced unit autonomously executes comprehensive device testing, ensuring the standby condition is meticulously monitored. It provides timely alerts for any anomalies, enhancing safety and preparedness.
Note: Our features are meticulously customizable to align with your specific requirements. Whether you seek standard offerings or desire bespoke solutions tailored to your unique needs, we are committed to delivering excellence and adaptability in every aspect.
