Performance Features
1. Equipped with 3 Superior Starting Functions:
(1). Manual Start Function: Achieving a seamless manual-automatic interlock through an intuitive switch for hassle-free manual starting.
(2). Automatic-Manual Functions: Featuring allowance for 3 starting attempts, issuing a "starter failure alarm" and automatically exiting the start state if unsuccessful. Upon first successful start, the system reaches rated load start time within an adjustable 5-10-15 seconds based on unit capacity.
(3). Emergency Manual Direct Start Function: In cases of self-controlled device failure, an emergency manual direct start function is readily accessible.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump automatically initiates running. If unable to start due to power supply issues with the fire pump motor, it seamlessly switches to electric pump mode once normal conditions resume.
3. Automatic Shutdown: The diesel fire-fighting pump gracefully shuts down automatically with a delay once the fire signal is no longer present, preserving system integrity.
4. Self-Charge Battery Feature: The battery is ingeniously designed to recharge automatically using the diesel engine's electrical mains power, ensuring a consistently smooth start.
5. Comprehensive Indicating System: Features ready-to-start, manual start, automatic start, unit operation, unit shutdown, battery charging, and critical alerts like low oil pressure and high water temperature, providing a complete operational overview.
6. Robust Alarm and Protection System: Equipped with alarms for start failures, overspeed, low lubricant oil pressure, and other critical conditions, safeguarding the system with unparalleled reliability.
7. State-of-the-Art Display Systems: Accurately displays engine oil pressure, engine speed, battery charge current, and voltage, ensuring continual monitoring for optimal performance.
8. Direct-Coupled Design: Diesel engine and water pump are seamlessly connected via a high-flexible coupling on a common channel base, featuring a compact structure with exceptional performance and minimal vibration, facilitating effortless installation.
9. High Pressure and Large Flow Capacity: Our selection of IS series single-stage, SOW series double-suction pumps, and SHD series multi-stage pumps cater to diverse fire-fighting scenarios with unmatched precision.
10. Adjustable Flow and Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow for precise adjustments to engine speed, ensuring harmony between pump flow and actual requirements.
11. Water Temperature Pre-Heating Device: An AC220V cooling water pre-heating device ensures optimal operation even in environments below 5ºC, maintaining reliability.
12. Dual Battery Circuitry: Automatically engages an alternate battery group upon failure, ensuring uninterrupted performance.
13. Maintenance-Free Battery: Enjoy the convenience of a maintenance-free battery, eliminating the need for frequent supplemental fluid additions.
14. Automatic Timing Inspection Test: In the realm of fire safety, where vigilance is key, our system usually remains in standby mode. However, it is engineered to autonomously execute device testing for standby conditions, ensuring peak readiness. Plus, it promptly issues timely warnings, fortifying your defense against unexpected fire hazards.
Note: The aforementioned functions are flexible and can be tailored to meet your specific requirements. We offer customized designs to accommodate distinct needs, ensuring our solutions align perfectly with your goals.
