Performance Features
1. Three Exceptional Starting Functions:
(1). Manual Start Function: Enjoy the simplicity of a manual-start function, seamlessly achieved through manual-automatic interlock via the switch;
(2). Automatic-Manual Functions: Offers three attempts for starting, issuing a 'starter failure alarm' and exiting the starting state if unsuccessful after three tries; Reaches rated load start within 5-10-15 seconds, based on unit capacity, after a successful initial start;
(3). Emergency Manual Direct Start Function: Provides a manual direct start option for emergencies when self-control devices fail.
2. Automatic Operation: When a valid fire signal is detected, the diesel fire pump will autonomously activate. If the pump cannot start due to power supply issues of the fire pump motor, it will seamlessly switch to the electric pump upon restoration of normal power supply or when electric pumps are operational.
3. Automatic Shutdown: Diesel fire-fighting pump will delay and automatically shutdown following the disappearance of the fire signal.
4. Battery Self-Charge Function: Ensures smooth unit starts by allowing automatic battery charging through the diesel engine's electrical mains power.
5. Comprehensive Indicating System: Alerts include ready to start, manual start, automatic start, unit operation, unit shutdown, battery charging, speeding, low oil pressure in lubrication oil, low turbocharger oil pressure, low lubricating oil temperature, high cooling system water temperature, low battery voltage, and low fuel level, ensuring regular inspection.
6. Advanced Alarm and Protection System: Features an alarm or protection for failures including three unsuccessful start attempts, overspeed, low lubricant oil pressure, low turbocharger oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device failures, low battery voltage, high battery voltage, and low fuel level.
7. Enhanced Display Systems: Provides real-time metrics including engine oil pressure, engine speed, battery charge current, and battery charging voltage, offering complete oversight.
8. Direct-Coupled Efficiency: The diesel engine and water pump are seamlessly connected via a high-flexible coupling on a common channel base, ensuring compact structure, exceptional overall performance, reduced failure and vibration, and easy installation during on-site construction.
9. High Pressure and Large Flow Capacity: Select from IS series single-stage single-suction, SOW series single-stage double-suction pump, or SHD series segmental multistage pumps, tailored to meet diverse fire scenario requirements.
10. Adjustable Flow and Working Pressure: Diesel pumps come equipped with mechanical or electronic speed governors, allowing adjustments to modify the diesel engine speed when pump flow and head vary from actual data.
11. Water Temperature Pre-Heating Device: Equipped with an AC220V cooling water preheating device to ensure optimal working conditions even at temperatures below 5 ºC.
12. Dual Battery Circuit: Automatically switches to an alternate battery upon failure of one group, ensuring continuous operation.
13. Maintenance-Free Battery: Enjoy hassle-free operation with no frequent need for supplemental fluid.
14. Automatic Timing Inspection Test: In the vigilant world of fire protection, our fire system remains in standby mode, yet it is ever-alert with the capability to autonomously conduct device testing. This ensures its readiness at all times and provides timely alerts, keeping your safety uncompromised.
Note: Tailor your experience with us; our versatile features are at your disposal to suit any unique requirements. We also offer bespoke design solutions to perfectly meet and exceed your specific needs.
