Performance Features
1. With Three Types of Perfect Starting Functions:
(1). Manual Start Function: Achieve manual start through manual-automatic interlock using a switch;
(2). Automatic-Manual Functions: Offers three starting attempts, issuing a 'starter failure alarm' and exiting the starting state if unsuccessful after three tries. The time to rated load after a successful start is 5-10-15 seconds, depending on unit capacity sizes;
(3). Emergency Manual Direct Start Function: Allows manual direct start in emergencies when self-controlled devices fail.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump will start automatically. If the pump fails to start due to power supply issues, it automatically switches to the electric pump once normal power resumes.
3. Automatic Shutdown: The diesel firefighting pump will automatically delay and shut down when the fire signal ceases.
4. Battery Self-Charge Function: Automatically charges the battery using the diesel engine's electrical mains power, ensuring smooth unit start-up.
5. Perfect Indicating System: Displays readiness to start, manual start, automatic start, unit operation, shutdown, battery charging, over-speed, low oil pressures, high temperatures, low voltages, and fuel levels, with regular inspection reminders.
6. Comprehensive Alarm and Protection System: Alerts for failed starts, overspeed, low lubricant oil pressures, high cooling water temperatures, low lubricating oil temperatures, automatic charging device failures, voltage irregularities, and low fuel levels.
7. Advanced Display Systems: Indicates engine oil pressure, engine speed, battery charge current, and voltage.
8. Direct-Coupled: Features a high-flexible coupling between the diesel engine and water pump on a common channel base, offering a compact structure, exceptional performance, reduced failure and vibration, and easy installation.
9. High Pressure and Big Flow Capacity: Choose between IS series single-stage, SOW series double-suction, or SHD series multistage pumps to accommodate various fire scenarios.
10. Adjustable Flow and Working Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow for adjustable engine speeds to match actual pump flow and head requirements.
11. Pre-Heating Device for Water Temperature: Equipped with an AC220V cooling water preheating device, the unit ensures optimal operation even below 5 ºC.
12. Double Battery Circuit: Provides automatic operation with a backup battery in case of failure in the primary battery.
13. Maintenance-Free Battery: Enjoy hassle-free battery performance without the need for frequent fluid supplements.
14. Automatic Timing Inspection Test: Our cutting-edge fire system is designed to remain vigilant, typically in standby mode. This advanced system autonomously conducts testing for standby conditions, ensuring optimal performance and issuing timely warnings whenever necessary.
Note: Each of the functions mentioned above can be tailored to meet the unique preferences of our users. We are also capable of crafting bespoke designs that cater to specific requirements, ensuring that every need is meticulously addressed.
