Remarkable Performance Features
1. Equipped with Three Outstanding Starting Functions:
(1) Manual Start Function: Achieve manual start through a manual-automatic switch interlock system;
(2) Automatic-Manual Functions: Allows for three start attempts, issuing a 'starter failure alarm' and automatically disengaging from starting mode if unsuccessful after three tries; the time to reach rated load is 5-10-15S (varies by unit capacity size) upon successful initial start.
(3) Emergency Manual Direct Start Function: Enable manual direct start during emergencies if the self-controlled device experiences failure.
2. Seamless Automatic Operation: In the event of receiving a valid fire signal, the diesel fire pump will autonomously initiate operation if the electric supply system for the fire pump motor is disrupted, or in the event of phase failure. Once normal power is restored or electric pumps become operational, it seamlessly transitions back to electric mode.
3. Intelligent Automatic Shutdown: The diesel fire-fighting pump will intuitively delay and shut down once the fire signal ceases.
4. Innovative Battery Self-Charge Function: The battery is automatically charged using the electrical mains power of the diesel engine, ensuring a seamless start.
5. Comprehensive Indicating System: Signals readiness to start, manual start, automatic start, unit operation, unit shutdown, battery charging, overspeed conditions, low oil pressure in both lubrication and turbocharger systems, low engine lubricating oil temperature, high water temperature in the cooling system, low battery voltage, diminishing fuel levels, and alerts for regular inspections.
6. Robust Alarm and Protection System: Provides alerts and protective measures for multiple scenarios including failure to start after three attempts, overspeed, low lubricant and turbocharger oil pressure, high cooling water temperature, low lubricant oil temperature, automatic charging device failure, low or high battery voltage, and low fuel level.
7. Advanced Display Systems: Monitors vital parameters including engine oil pressure, engine speed, battery charge current, and battery charging voltage.
8. Direct-Coupled Engineering: The diesel engine and water pump are seamlessly integrated via a high-flexible coupling on a common channel base, promoting a compact structure with superior overall performance, reduced failure rates, minimized vibrations, and ease of on-site installation.
9. Exceptional 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 cater to diverse fire emergency scenarios.
10. Adjustable Flow and Working Pressure: With mechanical or electronic speed governor-equipped diesel pumps, adapt easily to align pump flow and head with real-world conditions by modifying the diesel engine speed.
11. Pre-Heating Water Temperature Device: Outfitted with an AC220V cooling water preheating system to maintain optimal operational conditions even at temperatures below 5 ºC.
12. Dual Battery Circuit: Ensure reliability with a secondary battery that automatically engages if one fails.
13. Maintenance-Free Battery: No frequent supplemental fluid additions required, offering a hassle-free experience.
14. Automatic Timing Inspection Test: Engage in a seamless and robust automatic timing inspection test where the fire system, predominantly in standby mode, takes charge by autonomously executing device tests for standby conditions. This proactive system ensures that all operations are smoothly functioning while providing timely alerts to maintain optimal safety.
