Performance Features
1. Enjoy Three Distinct Starting Functions:
(1). Manual Start Function: Seamlessly achieve manual-start through manual-automatic interlock via a convenient switch;
(2). Automatic-Manual Functions: With allowance for three starting attempts, in the event of unsuccessful starts, a 'starter failure alarm' is issued and the system exits the starting phase. Upon successful initial start, the rated load start time is between 5-10-15 seconds, determined by unit capacity.
(3). Emergency Manual Direct Start Function: When self-controlled devices encounter failures, the emergency manual direct start function offers a swift solution.
2. Automatic Operation: When the pump unit receives a valid fire signal, if the pump fails to start due to issues with the power supply system of the fire pump motor, the diesel fire pump will automatically commence operation. Once the power supply returns to normal or electric pumps can operate correctly, it seamlessly transitions to the electric pump.
3. Automatic Shutdown: With precision, the diesel fire-fighting pump will delay and then automatically shut down when the fire signal is no longer present.
4. Battery Self-Charge Function: The battery benefits from automatic charging via the diesel engine's electrical mains power, ensuring a seamless and smooth start of the unit every time.
5. Advanced Indicating System: Stay informed with an impeccable indicating system that includes notifications for ready-to-start, manual start, automatic start, unit operation, unit shutdown, battery charging, speeding, low lubrication oil pressure, low turbocharger oil pressure, low engine lubricating oil temperature, high cooling system water temperature, low battery voltage, low fuel level, and regular inspection.
6. Comprehensive Alarm and Protection System: Benefit from a sophisticated alarm and protection suite, encompassing alerts for three failed start attempts, overspeed, low lubricant oil pressure, low turbocharger oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device failures, low battery voltage, high battery voltage, and low fuel level.
7. State-of-the-Art Display Systems: Effortlessly monitor key metrics such as engine oil pressure, engine speed, battery charge current, and battery charging voltage for optimal performance.
8. Precision Direct-Coupling: The diesel engine and water pump are expertly linked via a high-flexible coupling on a shared channel base. This design ensures a compact structure with superb overall performance, reduced failure and vibration, and convenient on-site construction installation.
9. Exceptional High-Pressure and Large Flow Capacity: Choose from IS series single-stage single-suction pumps, SOW series single-stage double-suction pumps, or SHD series segmental multistage pumps to perfectly cater to the unique demands of varying fire emergencies.
10. Adjustable Flow and Working Pressure: Equipped with either mechanical or electronic speed governors, these diesel pumps provide flexibility to adjust the engine speed when pump flow and head don't match actual requirements.
11. Pre-Heating Device for Water Temperature: Outfitted with an AC220V cooling water pre-heating unit, the system ensures normal functioning even at temperatures below 5 ºC.
12. Dual Battery Circuit: Should one battery fail, the alternate battery is automatically activated, ensuring uninterrupted operation.
13. Maintenance-Free Battery: Enjoy the convenience of a maintenance-free battery that eliminates the frequent need for supplemental fluid.
14. Automatic Timing Inspection Test: In situations where the fire system typically remains in a standby mode, our unit ingeniously undertakes automatic device testing to ensure the system's readiness. It provides timely warnings, guaranteeing optimal performance and reliability in standby conditions.
Note: The features listed above are selectable based on the unique requirements of our users. We pride ourselves on our flexibility, offering tailored solutions through customized design to meet specific needs.
