Performance Features
1. With 3 Types of Perfect Starting Functions:
(1). Manual Start Function: Experience seamless operation with the manual-start function, which is effortlessly activated via a manual-automatic interlock switch.
(2). Automatic-Manual Functions: Benefit from the allowance of 3 starting attempts. A 'starter failure alarm' will notify you, and the system will automatically exit the starting state if unsuccessful after three attempts. Enjoy swift operation with a rated load start time of 5-10-15 seconds, depending on unit capacity, post successful initial start.
(3). Emergency Manual Direct Start Function: Empower yourself with a direct manual start capability for emergencies, ensuring seamless operation even when automatic systems face disruptions.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump automatically springs into action. If the pump fails to start due to power supply interruptions in the fire pump motor, it switches to the diesel pump. Once normal power supply resumes or electric pumps are operational, it automatically reverts to the electric pump, ensuring uninterrupted fire safety.
3. Automatic Shutdown: The diesel fire-fighting pump intelligently delays and shuts down once the fire signal ceases, ensuring precise control and safety.
4. The Battery Self-Charge Function: Harness the convenience of an automatic battery charging system, powered by the diesel engine's mains electricity, guaranteeing a reliable start whenever needed.
5. Perfect Indicating System: Enjoy a comprehensive system that indicates readiness to start, manual and automatic starts, unit operation and shutdown, battery charging, and various alerts for system performance, ensuring complete operational transparency.
6. Perfect Alarm or Protection System: Our sophisticated alarm and protection system keeps you informed and protected against potential issues such as failed starts, overspeed, low lubricant oil pressure, high cooling water temperature, and more, ensuring optimum system reliability.
7. Perfect Display Systems: Monitor crucial parameters effortlessly, including engine oil pressure, engine speed, battery charge current, and charging voltage, with our advanced display systems.
8. Direct-Coupled: Experience seamless efficiency with diesel engines and water pumps directly connected via high-flexible coupling on a common channel base, delivering a compact, reliable structure with minimal vibration and site-friendly installation.
