Performance Features
1. With three impeccable starting functions:
(1). Manual Start Function: Achieve manual start through an intuitive manual-automatic interlock using a switch;
(2). Automatic-Manual Functions: Offers three attempts for starting, with a "starter failure alarm" and automatic cessation of starting attempts if unsuccessful. Post-success, initiate rated load within 5-10-15 seconds, tailored by unit capacity.
(3). Emergency Manual Direct Start: In emergencies, manually initiate direct start when self-controlled systems encounter failures.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump autonomously springs into action when impeded by issues like power supply interruptions. It seamlessly switches back to electric operation once normalcy is restored.
3. Automatic Shutdown: The diesel fire-fighting pump automatically delays and shuts down when the fire signal dissipates, ensuring safety and efficiency.
4. Battery Self-Charge Function: The battery is automatically charged by the diesel engine's electrical mains, guaranteeing a smooth and reliable unit start every time.
5. Comprehensive Indicating System: Displays ready status, manual and automatic starts, unit operation, shutdown, battery charging, over-speeding, low lubrication oil pressure, low turbocharger oil pressure, low oil temperature, high cooling system temperature, low battery voltage, low fuel level, and regular inspection alerts.
6. Advanced Alarm and Protection System: Proactive alerts for three consecutive start failures, over-speed conditions, low lubricant oil and turbocharger oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device failures, and voltage irregularities.
7. Advanced Display Systems: Real-time monitoring of engine oil pressure, engine speed, battery charge current, and voltage.
8. Direct-Coupled Excellence: Diesel engine and water pump are ingeniously joined via a high-flexible coupling on a unified channel base, yielding a compact structure with exceptional performance, minimal failure, reduced vibration, and convenient on-site installation.
