Performance features
1. Featuring three flawless starting functions:
(1). Manual start function: Experience seamless manual-start functionality, achieved through manual-automatic interlock via a switch;
(2). Automatic-manual functions: Enjoy 3 attempts at automatic starting. If unsuccessful, a 'starter failure alarm' will be issued, and the system will automatically exit the starting state. The time to reach rated load is adjustable: 5, 10, or 15 seconds, depending on unit capacity, after the first successful start;
(3). Emergency manual direct start function: In emergencies, when the self-controlled device fails, manually initiate the direct start function with ease.
2. Automatic operation: Upon receiving a valid fire signal, the diesel fire pump will automatically commence operation if the normal start is hindered by an interruption or failure in the fire pump motor's power supply system. Once normal power is restored or electric pumps can function properly, the system seamlessly switches back to the electric pump.
3. Automatic shutdown: Following the disappearance of the fire signal, the diesel firefighting pump will initiate a delayed automatic shutdown.
4. The battery self-charge function: The system ensures a smooth start by automatically charging the battery using the diesel engine's electrical mains power.
5. Comprehensive indicating system: Stay informed with indicators for ready-to-start, manual start, automatic start, unit operation, shutdown, battery charging, overspeeding, and low levels of lubrication oil pressure, turbocharger oil pressure, engine lubricating oil temperature, cooling system water temperature, battery voltage, and fuel level, along with regular inspection alerts.
6. Advanced alarm and protection system: Benefit from alarms or protective measures for three-time unsuccessful starts, overspeed conditions, low lubricant oil pressure, turbocharger oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device failures, low and high battery voltage, and low fuel levels.
7. Superior display systems: Clear readings of engine oil pressure, engine speed, battery charge current, and battery charging voltage.
8. Direct-coupled design: The diesel engine and water pump are expertly connected with a high-flexible coupling on a common channel base. This offers a compact structure with exceptional performance, reduced failure and vibration, and straightforward on-site installation.
9. 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 fulfill diverse firefighting demands with remarkable precision.
10. Adjustable flow and working pressure: Diesel pumps equipped with mechanical or electronic speed governors allow for seamless adjustments, ensuring the diesel engine speed aligns perfectly with actual pump flow and head requirements.
11. Pre-heating water temperature device: Equipped with an AC220V cooling water preheating device, guaranteeing reliable functionality even in environments below 5 ºC.
12. Dual battery circuit: In the event of a battery group failure, the system automatically engages the alternate battery, ensuring uninterrupted operation.
13. Maintenance-free battery: Designed for convenience, these batteries eliminate the need for frequent fluid supplementation.
14. Automatic Timing Inspection Test: In a remarkable display of efficiency, the fire system, typically in standby mode, has the capability to autonomously execute comprehensive device testing, ensuring optimal standby conditions and providing timely alerts for any anomalies.
Note: The above functionalities are thoughtfully designed to align with user needs, offering flexibility for customization. We are equipped to offer tailor-made solutions that cater specifically to your unique requirements, ensuring unparalleled satisfaction.
