Performance Features
1. Three Remarkable Starting Functions:
(1). Manual Start Function: Experience seamless control with manual-automatic interlock achieved through a switch, offering a reliable manual-start capability.
(2). Automatic-Manual Functions: Allowance for three starting attempts— if unsuccessful, a 'starter failure alarm' is triggered, automatically exiting the starting state. After a successful initial start, the time to reach rated load is an impressive 5-10-15 seconds, depending on unit capacity size.
(3). Emergency Manual Direct Start Function: In the unlikely event of self-controlled device failure, an emergency manual direct start function is available for immediate activation.
2. Automatic Operation: When a valid fire signal is received, the diesel fire pump springs into action, automatically starting if the pump cannot commence due to interruptions or failures in the fire pump motor power supply system. Once normal power supply resumes or electric pumps function correctly, it seamlessly switches to electric pumping.
3. Automatic Shutdown: The diesel fire-fighting pump intelligently delays and automatically shuts down when the fire signal dissipates, ensuring efficient operation.
4. Battery Self-Charge Function: Experience uninterrupted operations with automatic battery charging powered by the diesel engine's electrical mains, guaranteeing a reliable start every time.
5. Comprehensive Indicating System: Stay informed with indicators for ready-to-start, manual start, automatic start, unit operation, unit shutdown, battery charging, overspeed, low oil pressure, high water temperature, low voltage, low fuel level, and more, ensuring regular inspections are a breeze.
6. Advanced Alarm and Protection System: Our sophisticated system alerts you to issues such as failure to start after three attempts, overspeed, low oil pressure, high cooling water temperature, low battery voltage, high battery voltage, and low fuel level, along with automatic charging device failures.
7. Precision Display Systems: Monitor engine oil pressure, engine speed, battery charge current, and battery charging voltage effortlessly with our precise display systems.
8. Direct-Coupled Excellence: Featuring a high-flexible coupling that seamlessly connects the diesel engine and water pump on a shared channel base. This compact structure ensures outstanding performance, minimized failure and vibration, and effortless on-site 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, tailored to meet the demanding needs of various fire scenarios.
10. Adjustable Flow and Working Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow for precise adjustments, ensuring diesel engine speed aligns with actual flow and head data, optimizing performance.
11. Pre-Heating Device for Water Temperature: Equipped with an AC220V cooling water preheating device, ensuring optimal operation even in environments as low as 5 ºC.
12. Dual Battery Circuit: In the event of a battery group failure, an alternative battery is automatically activated, ensuring seamless operation.
13. Maintenance-Free Battery: Enjoy the convenience of a maintenance-free battery, eliminating the need for frequent supplemental fluid additions.
14. Automatic Timing Inspection Test: In the realm of fire safety, where vigilance is paramount, our system remains in a perpetual standby mode, poised to spring into action. This advanced unit autonomously executes device inspections for optimal standby readiness, ensuring timely alerts for enhanced security and peace of mind.
