Performance Features Overview
1. Comprehensive Starting Functions:
(1). Manual Start Function: Achieve manual start through a seamless manual-automatic interlock utilizing a convenient switch.
(2). Automatic-Manual Functions: Offers three starting attempts, alerting with a 'starter failure alarm' if unsuccessful after three tries. The system exits the starting mode automatically. The transition to rated load initiation varies between 5-10-15 seconds, depending on unit capacity, post successful initial start.
(3). Emergency Manual Direct Start: An emergency direct start function is accessible manually when there is a self-control device malfunction.
2. Automatic Operation: Upon receiving a legitimate fire signal, the diesel fire pump will activate automatically if the pump fails to start normally due to power supply interruptions or system failures. Once the power supply stabilizes or electric pumps operate correctly, the system will transition back to using the electric pump.
3. Automatic Shutdown: The diesel fire-fighting pump will initiate a delay before automatically shutting down when the fire signal is no longer detected.
4. Self-Charging Battery Function: The battery harnesses electrical mains power from the diesel engine for automatic charging, ensuring the unit is perpetually ready for a smooth start.
5. Advanced Indicating System: Designed to signal readiness, manual start, automatic start, operation, shutdown, battery charging, and conditions like speeding, low oil pressure, high cooling system temperature, and more. It also includes indicators for regular inspections.
6. Comprehensive Alarm and Protection System: Offers robust alerts and protections against conditions such as failure to start thrice, overspeed, low oil pressure, cooling water overheating, lubricating oil temperature anomalies, and automatic charging device failures, among others.
7. Precision Display Systems: Monitors critical metrics such as engine oil pressure, engine speed, battery charge current, and battery charging voltage.
8. Direct-Coupled Innovation: The diesel engine seamlessly connects to the water pump via a high-flexible coupling on a unified channel base, ensuring a compact structure and superior overall performance with minimized failure and vibration, facilitating straightforward on-site installation.
9. Elevated Pressure and High Flow Capacity: Select from IS series single-stage single-suction, SOW series single-stage double-suction, or SHD series segmental multistage pumps to cater to diverse fire-fighting scenarios.
10. Adjustable Flow and Pressure: Diesel pumps equipped with mechanical or electronic speed governors enable flexible speed adjustment, aligning pump flow and head with actual operational data.
11. Pre-Heating Device for Water Temperature: Equipped with an AC220V cooling water preheating device, the unit ensures optimal operation even when ambient temperatures dip below 5 ºC.
12. Dual Battery Circuit: In case of one battery group's failure, the alternative group automatically activates.
13. Maintenance-Free Battery: Designed for minimal fluid replenishment, thus eliminating frequent maintenance needs.
14. Automatic Timing Inspection Test: In the world of fire safety, systems often remain in a vigilant standby mode, ever-prepared for action. Our innovative unit excels by autonomously conducting comprehensive device testing to ensure readiness. It simultaneously generates timely warnings, safeguarding your peace of mind and operational efficiency.
