Performance features
1, With 3 types of perfect starting-functions:
(1). Manual start function: Achieve manual start functionality with seamless manual-automatic interlock via switch operation;
(2). Automatic-manual functions: Enabling three starting attempts, the system issues a 'starter failure alarm' and automatically exits the starting state if unsuccessful after three tries. Post initial successful start, the rated load start time ranges between 5-10-15 seconds, contingent on unit capacity sizes;
(3). Emergency manual direct start function: In cases of self-controlled device failures, the system offers a manual direct start capability for emergencies.
2. Automatic operation: Upon receiving a valid fire signal, the diesel fire pump autonomously initiates operation if the pump fails to start due to a power supply disruption or motor issues. Once the system restores normal power supply or the electric pump becomes operational again, automatic switching to the electric pump occurs seamlessly.
3. Automatic shutdown: The diesel fire-fighting pump intelligently delays and automatically shuts down when the fire signal ceases, ensuring safety and efficiency.
4. The battery self-charge function: Harnessing the electrical mains power of the diesel engine, the battery charges automatically, ensuring a confident and smooth unit start-up every time.
5. Perfect indicating system: Equipped with comprehensive indicators for statuses such as ready to start, manual start, automatic start, unit operation, shutdown, battery charging, speeding, low oil pressures, high cooling system temperatures, low battery voltage, low fuel levels, and more, ensuring thorough monitoring and control.
6. Perfect alarm or protection system: Features robust alarm and protection mechanisms against multiple factors including starter failure after three attempts, overspeed, low lubricant oil pressures, high water temperatures, and more, providing a safeguard for optimal operation.
7. Perfect display systems: Display systems provide real-time monitoring of engine oil pressure, engine speed, battery charge current, and voltage, ensuring constant oversight of operational parameters.
8. Direct-coupled: Engineered with a high-flexible coupling that seamlessly connects the diesel engine and water pump on a common channel base, this setup boasts a compact structure that delivers outstanding overall performance, minimizing failure and vibration, and facilitating straightforward on-site installation.
9. High-pressure and big-flow capacity: By selecting from IS series single-stage single-suction, SOW series single-stage double-suction, or SHD series segmental multistage pumps, our pumps cater to the diverse demands of any fire scenario with unmatched efficiency.
10. Flow and working pressure adjustability: Diesel pumps equipped with mechanical or electronic speed governors allow for speed adjustments of the diesel engine, accommodating inconsistencies between pump flow/head and actual requirements, enhancing precision and efficiency.
11. Pre-heating device for water temperature: Outfitted with an AC220V cooling water preheating device, this unit assures optimal functionality even when ambient temperatures drop below 5 ºC, maintaining reliable performance.
12. Dual battery circuit: In the event of a battery group failure, the system automatically activates an alternate battery, ensuring uninterrupted operation.
13. Maintenance-free battery: Engineered for convenience, our maintenance-free battery design eliminates the frequent need for supplemental fluid, offering users a hassle-free experience.
14. Automatic Timing Inspection Test: Fire systems generally remain in standby mode, yet this unit is engineered to automatically conduct comprehensive device testing while in standby. It ensures timely alerts if any issues arise, safeguarding system readiness.
Note: The features listed above are customizable. We offer tailored solutions to perfectly meet your specific requirements and preferences, ensuring that the product aligns seamlessly with your needs.
