Comprehensive Indicating System: Features a sophisticated array of indicators including: ready to start, manual start, automatic start, unit operation, unit shutdown, battery charging, overspeed, low oil pressure of lubrication oil, low oil pressure of turbocharger, low oil temperature of engine lubricating, high water temperature of cooling system, low battery voltage, and low fuel level, along with reminders for regular inspections.
6. Advanced Alarm and Protection System: Includes alerts for failure to start after three attempts, overspeed, low lubricant oil pressure, low oil pressure of turbocharger, high cooling water temperature, low lubricating oil temperature, automatic charging device failure, low battery voltage, high battery voltage, and low fuel level, ensuring maximum safety and performance.
7. Sophisticated Display Systems: Real-time monitoring of engine oil pressure, engine speed, battery charge current, and battery charging voltage, providing essential data at a glance.
8. Direct-Coupled Design: Featuring a high-flexible coupling that connects the diesel engine and water pump on a common channel base, offering a compact structure with exceptional overall performance, reduced failure and vibration, and convenient on-site installation.
9. High Pressure and Large Flow Capacity: With options such as IS series single-stage single-suction, SOW series single-stage double-suction pump, and SHD series segmented multistage pumps, our system is tailored to meet the rigorous demands of various fire scenarios.
10. Adjustable Flow and Working Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow for precise adjustment, enabling changes in diesel engine speed when pump flow and head differ from actual data, ensuring optimal performance.
11. Water Temperature Pre-Heating Device: Equipped with an AC220V cooling water preheating device, this feature guarantees efficient operation in environments where temperatures drop below 5ºC.
12. Double Battery Circuit: Automatically activates an alternate battery circuit when one battery group fails, ensuring uninterrupted operation.
13. Maintenance-Free Battery: Designed to eliminate the frequent need for supplemental fluid, offering a hassle-free experience.
14. Automatic Timing Inspection Test: In a fire system, typically operating in a standby mode, our unit seamlessly automates device testing, ensuring optimal performance under standby conditions. It also provides timely alerts and warnings to guarantee system readiness.
Note: Our range of functions can be customized to perfectly align with user requirements. Additionally, we offer bespoke design services to cater to specific, individualized needs, ensuring every customer receives the ideal solution.
