Performance Features
1. Three Exceptional Starting Functions:
(1). Manual Start Function: Seamlessly initiate the pump with the manual-start feature through manual-automatic interlock via a switch;
(2). Automatic-Manual Functions: With the ability to attempt starting thrice, if unsuccessful, it triggers a "starter failure alarm" and exits the start sequence. Once successfully started, the time to reach rated load ranges from 5 to 15 seconds, depending on unit capacity;
(3). Emergency Manual Direct Start: In case of self-controlled device failure, this function allows for direct manual initiation during emergencies.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump autonomously commences operation if the regular power supply to the fire pump motor fails. Once the power supply stabilizes or electric pumps resume normal functionality, it seamlessly transitions back to electric operation.
3. Automatic Shutdown: The diesel fire-fighting pump automatically delays and ceases operation once the fire signal dissipates.
4. Battery Self-Charge Capability: The battery is charged automatically via the diesel engine's electrical mains, ensuring the unit starts smoothly every time.
5. Comprehensive Indicating System: This system provides real-time status updates on readiness, manual and automatic starts, operation, shutdown, battery charging, speed monitoring, low oil pressures, turbocharger oil levels, and more, facilitating regular inspections and reliable operations.
6. Superior Alarm and Protection System: Equipped with alerts for multiple scenarios including failure to start after three attempts, overspeed conditions, low lubricant and turbocharger pressures, high cooling water temperature, lubrication oil temperature, automatic charging malfunction, low and high battery voltage, and insufficient fuel levels.
7. Advanced Display Systems: Features include real-time monitoring of engine oil pressure, engine speed, battery charging current, and voltage, ensuring optimal performance and efficiency.
8. Direct-Coupled Design: The diesel engine and water pump are meticulously connected through a high-flexible coupling on a common channel base, offering a compact structure, superior performance, reduced failure rates, minimal vibration, and easy on-site installation.
9. High Pressure and Large Flow Capacity: With options like IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmented multistage pumps, these pumps are designed to cater to diverse fire-fighting scenarios and requirements.
10. Adjustable Flow and Working Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow for precise adjustments, ensuring the flow and head are perfectly aligned with actual operational data.
11. Pre-heating Device for Water Temperature: Equipped with an AC220V cooling water preheating device, the unit guarantees optimal performance even in temperatures as low as 5 ºC, ensuring reliability in cold environments.
12. Double Battery Circuit: If one battery set fails, another seamlessly takes over, ensuring uninterrupted operation.
13. Maintenance-Free Battery: Designed for convenience, these batteries do not require frequent fluid supplementation, reducing maintenance needs.
14. Automatic Timing Inspection Test: In the realm of fire safety, our system is your vigilant guardian, always in standby mode, yet ever-ready. The unit seamlessly conducts automatic device testing for standby conditions, ensuring timely alerts and unwavering readiness.
Note: The above functions are merely a glimpse of what's possible. Users can tailor these features to their specific needs, and we are delighted to offer bespoke designs to meet your unique requirements.
