Performance Features
1. Equipped with 3 Distinct Starting Functions:
(1). Manual Start Function: The manual-start function allows seamless switching between manual and automatic modes via an interlock switch.
(2). Automatic-Manual Functions: This feature permits up to three starting attempts, issuing a 'starter failure alarm' and automatically ceasing further attempts if unsuccessful. Upon the first successful start, it reaches the rated load in 5-10-15 seconds, depending on unit capacity.
(3). Emergency Manual Direct Start Function: In the event of a self-controlled device failure, direct manual start can be executed for emergencies.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump initiates automatically if the usual power supply to the fire pump motor is interrupted. Once normal power resumes, it seamlessly switches back to the electric pump mode.
3. Automatic Shutdown: When the fire signal ceases, the diesel fire-fighting pump will delay briefly before automatically shutting down.
4. Battery Self-Charge Function: The battery is autonomously charged via the diesel engine's electrical mains, ensuring consistent readiness for operation.
5. Comprehensive Indicating System: Features include indicators for readiness, manual and automatic start, unit operation, shutdown, battery charging, over-speeding, low oil pressures, high water temperature, low battery voltage, and fuel monitoring.
6. Advanced Alarm and Protection System: Encompasses alarms for failed starts, over-speeding, low lubricant oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device issues, and fuel depletion.
7. Sophisticated Display Systems: Showcases critical metrics such as engine oil pressure, engine speed, battery charge current, and voltage.
8. Direct-Coupled Design: The diesel engine and water pump are unified through a high-flexible coupling on a common channel base, ensuring compact structure, superior performance, reduced failures, decreased vibrations, and ease of on-site installation.
9. High Pressure and Large Flow Capacity: Choose from IS series single-stage single-suction, SOW series single-stage double-suction, or SHD series segmental multistage pumps to cater to diverse fire scenarios.
10. Adjustable Flow and Pressure: Diesel pumps with mechanical or electronic speed governors allow for speed adjustments to match actual flow and head data.
11. Water Temperature Pre-Heating Device: Equipped with an AC220V cooling water pre-heating system, this unit assures normal operation in environments below 5 ºC.
12. Dual Battery Circuits: In case of one battery's failure, the other automatically takes over, ensuring uninterrupted operation.
13. Maintenance-Free Battery: Enjoy the convenience of a battery that requires no frequent fluid top-ups.
14. Automatic Timing Inspection Test: In the realm of advanced fire safety systems, our product is designed to remain in a constant state of readiness. The unit can autonomously execute device testing to ensure standby conditions are optimal, and provide timely warnings for peace of mind.
Note: Customize your experience! The functions listed can be tailored to meet specific user requirements. We also offer bespoke designs crafted to cater to unique needs.
