Performance Features
1. Three Flawless Starting Functions:
(1). Manual Start Function: Achieve manual start through a manual-automatic interlock facilitated by a switch, ensuring seamless initiation.
(2). Automatic-Manual Functions: Provides three attempts for starting, issuing a 'starter failure alarm' and automatically exiting the start state if unsuccessful. The time to achieve rated load ranges from 5-10-15 seconds, depending on unit capacity, following the first successful start.
(3). Emergency Manual Direct Start Function: In case of self-control device failures, an emergency manual direct start function is available, ensuring uninterrupted operation.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump springs into action. If normal startup is hindered due to power supply interruptions or failures, once resolved, it seamlessly switches back to electric pump operation.
3. Automatic Shutdown: The diesel fire-fighting pump intelligently delays and ceases operation once the fire signal dissipates.
4. Battery Self-Charge Function: The battery benefits from automatic charging via the diesel engine's electrical mains power, guaranteeing a reliable start.
5. Comprehensive Indicating System: Features readiness to start, manual start, automatic start, unit operation, unit shutdown, battery charging, speeding, low lubricant oil pressure, turbocharger oil pressure, engine lubricating oil temperature, cooling system water temperature, battery voltage, fuel level, and regular inspection indicators.
6. Advanced Alarm and Protection System: Offers alerts or protection for start failures, overspeed, low lubricant oil pressure, turbocharger oil pressure, cooling water temperature, lubricating oil temperature, charging device failure, battery voltage, and fuel level.
7. Enhanced Display Systems: Monitors engine oil pressure, engine speed, battery charge current, and charging voltage, providing comprehensive insights.
8. Direct-Coupled Design: Diesel engine and water pump are seamlessly connected by a high-flexible coupling on a common channel base, boasting a compact structure, superior performance, minimal failure, and vibration, facilitating easy on-site installation.
9. High Pressure and Large Flow Capacity: By leveraging IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps, we address diverse fire protection scenarios effectively.
10. Adjustable Flow and Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow speed adjustments to accommodate inconsistent pump flow and head with actual data.
11. Pre-Heating Device for Water Temperature: An AC220V cooling water preheating device ensures optimal operation in environments below 5 ºC.
12. Double Battery Circuit: In the event of one battery group's failure, the alternate group automatically takes over, ensuring continuous operation.
13. Maintenance-Free Battery: Enjoy hassle-free operation with batteries that eliminate the need for frequent fluid supplementation.
14. Automatic Timing Inspection Test: In the realm of fire safety, where every moment counts, our system remains vigilantly in standby mode, poised to ensure optimal performance. This state-of-the-art unit seamlessly executes device testing during standby conditions, offering timely alerts that promise peace of mind and reliability.
Note: Tailor the experience to your specifics. The listed functions are flexible and can be curated based on unique user requirements. Our expertise allows us to offer bespoke designs that align perfectly with your distinctive needs, ensuring a seamless integration into your operations.
