Performance features
1. Equipped with three impeccable starting functions:
(1). Manual start function: Achieve manual start seamlessly through manual-automatic interlock, utilizing a convenient switch;
(2). Automatic-manual start functions: Enables up to 3 attempts, if all fail, a "starter failure alarm" is triggered, automatically exiting the starting state. Once started, the load time to reach rated capacity is adjustable between 5, 10, and 15 seconds based on unit capacity;
(3). Emergency manual direct start function: In emergencies, manually initiate direct start even if the self-controlled device fails.
2. Automatic operation: Upon receiving a valid fire signal, the diesel fire pump initiates automatic operation. If the pump fails to start due to power supply issues, it automatically transitions to electric mode when systems normalize, ensuring continuous protection.
3. Automatic shutdown: The diesel fire-fighting pump gracefully delays before shutting down automatically once the fire signal ceases, ensuring seamless operation.
4. Self-charging battery function: The battery maintains optimal charge through automatic electrical mains power, facilitating smooth unit startups.
5. Comprehensive indicating system: Stay informed with indicators for readiness to start, manual/automatic start, unit operation/shutdown, battery charging, speed changes, oil pressure, and essential system parameters.
6. Robust alarm and protection system: Features alerts for starting failures, overspeed, low lubricant oil pressure, high cooling water temperature, and automatic charger issues, ensuring resilient operation.
7. Advanced display systems: Monitor engine oil pressure, engine speed, battery charge current, and battery charging voltage effortlessly through cutting-edge display systems.
8. Direct-coupled design: Diesel engine and water pump are seamlessly integrated via high-flexible coupling on a shared channel base. This design ensures compactness, superior performance, minimal failure, vibration reduction, 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, achieving unmatched pressure and flow rates.
10. Adjustable flow and working pressure: Diesel pumps feature mechanical or electronic speed governors, allowing precise adjustment of engine speed to align with actual flow and head data.
11. Water temperature pre-heating device: Ensure optimal operations in cold environments with the AC220V cooling water pre-heating device, designed to perform efficiently even at temperatures below 5 ºC.
12. Dual battery circuit: In case of one battery's failure, the system automatically switches to the backup battery, ensuring uninterrupted operation.
13. Maintenance-free battery: Eliminate frequent fluid additions with our maintenance-free battery, enhancing convenience and reliability.
14. Automatic Timing Inspection Test: In the realm of fire safety, our system predominantly remains in standby mode. However, it is engineered to autonomously conduct device testing, ensuring optimal standby conditions while providing timely alerts for any inconsistencies.
Note: The aforementioned functionalities are available for selection based on user preferences. We proudly offer bespoke design solutions tailored to meet specific requirements, ensuring a personalized approach to your needs.
