Performance Features
1. Unmatched starting capabilities with three distinct functions:
(1). Manual Start Function: Achieve manual start through an intuitive manual-automatic interlock switch;
(2). Automatic-Manual Functions: Permitting three starting attempts, a 'starter failure alarm' is issued, automatically exiting the start state if attempts are unsuccessful. Time to reach rated load varies by unit capacity, with a start time of 5-10-15 seconds after a successful start.
(3). Emergency Manual Direct Start Function: In emergencies, a manual direct start can be performed when self-controlled devices fail.
2. Seamless Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump automatically initiates. In the event of power supply interruptions, it takes over immediately, switching back to an electric pump once normal power resumes.
3. Automatic Shutdown: The diesel fire-fighting pump gracefully delays and shuts down automatically when the fire signal is no longer detected.
4. Self-Sustaining Battery Charge Function: The battery charges itself automatically through the electrical mains of the diesel engine, ensuring a seamless start-up every time.
5. Comprehensive Indicating System: Signals readiness to start, manual start, automatic start, unit operation, shutdown, battery charging, and alerts for speeding, lubrication oil pressure, turbocharger pressure, engine lubricating oil temperature, cooling system water temperature, battery voltage, and fuel levels, alongside regular inspections.
6. Advanced Alarm and Protection System: Safeguards against starter failure after three attempts, overspeed, low lubricant and turbocharger oil pressure, high cooling water temperature, low lubricating oil temperature, charging device failures, and battery voltage abnormalities, ensuring optimal operation.
7. State-of-the-Art Display Systems: Monitor engine oil pressure, engine speed, battery charge current, and charging voltage with precision.
8. Direct-Coupled Excellence: The diesel engine and water pump are seamlessly connected by a high-flexible coupling on a shared channel base, offering a compact structure, impeccable performance, minimal failure and vibration, and easy on-site installation.
9. High Pressure and Large Flow Capacity: With options like IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps, our pumps are engineered to meet diverse fire-fighting scenarios.
10. Adjustable Flow and Pressure: Equipped with mechanical or electronic speed governors, our diesel pumps adjust speed to harmonize pump flow and head with real-time data.
11. Pre-Heating Device for Water Temperature: Featuring an AC220V cooling water preheating device, the unit is guaranteed to perform effectively even in temperatures below 5 ºC.
12. Dual Battery Circuit: If one battery group fails, another is automatically deployed, ensuring uninterrupted operation.
13. Maintenance-Free Battery: Designed for convenience, it eliminates the frequent need to add supplemental fluid.
14. Automatic Timing Inspection Test: In the realm of fire safety excellence, the system stands vigilant in standby mode, poised to autonomously execute comprehensive device testing. This ensures that any standby condition is monitored, with timely warnings dispatched to guarantee optimal preparedness.
Note: The functions highlighted above are meticulously crafted to be tailored to your specific requirements. Embrace the luxury of customization, as we offer bespoke design services that cater precisely to your unique needs and preferences.
