Performance Features
1. Unmatched Starting Capabilities with Three Distinct Functions:
(1). Manual Start Function: Seamlessly achieve manual-start through a manual-automatic interlock via the switch;
(2). Automatic-Manual Functions: This feature allows for three starting attempts, triggers a 'starter failure alarm', and automatically exits the starting mode if unsuccessful after three attempts. The time to reach rated load varies between 5-10-15 seconds depending on the unit's capacity, following a successful first start.
(3). Emergency Manual Direct Start Function: Ensure immediate activation in emergencies through a manual direct start function if the self-controlled device encounters issues.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump will autonomously commence operations if the power supply to the fire pump motor is interrupted or phases out. Once the power supply resumes or electric pumps are operational, the system will automatically switch back to electric pumping.
3. Automatic Shutdown: The diesel fire-fighting pump intelligently delays and automatically ceases operation once the fire signal is no longer detected.
4. Battery Self-Charge Function: The unit ensures seamless starting by automatically charging the battery using the diesel engine's electrical mains power.
5. Comprehensive Indicating System: Displays indicators for ready-to-start, manual start, automatic start, unit operation, shutdown, battery charging, and more, including parameters like low oil pressure, high water temperature, and low fuel level.
6. Complete Alarm and Protection System: Provides alarms and protection for issues like failure to start after three attempts, overspeed, low lubricant oil pressure, and more, ensuring the system's safety and reliability.
7. Advanced Display Systems: Engine oil pressure, engine speed, battery charge current, and battery charging voltage are all displayed for comprehensive monitoring.
8. Direct-Coupled Advantage: The diesel engine and water pump are expertly connected through a high-flexible coupling on a common channel base, offering a compact structure, outstanding overall performance, minimal failure and vibration, and hassle-free on-site installation.
9. High Pressure and Large Flow Capacity: By choosing from the IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps, we cater to the diverse demands of various fire scenarios.
10. Adjustable Flow and Working Pressure: Diesel pumps are equipped with mechanical or electronic speed governors, allowing for speed adjustments to match the diesel engine's flow and head with actual requirements.
11. Water Temperature Pre-Heating Device: Equipped with an AC220V cooling water preheating system, ensuring optimal operation even in environments with temperatures below 5 ºC.
12. Dual Battery Circuit: In case of a battery failure, the system automatically switches to an alternate battery, guaranteeing uninterrupted performance.
13. Maintenance-Free Battery: This innovative battery design eliminates the need for frequent supplemental fluid additions, offering a truly maintenance-free experience.
14. Automatic Timing Inspection Test: In the realm of fire systems, where constant vigilance is paramount, the system typically remains in standby mode. However, with our advanced technology, the unit can autonomously execute device tests to ensure ideal standby conditions, all while providing immediate alerts to any irregularities.
Note: The aforementioned functions are customizable to align with user specifications. We are adept at crafting bespoke designs tailored to meet unique and specific requirements, ensuring a perfect fit for any need.
