Performance Features
1. Three Types of Perfect Starting Functions:
(1) Manual Start Function: Seamlessly transition between manual and automatic start through an easy-to-use switch, ensuring operational flexibility.
(2) Automatic-Manual Functions: Enjoy the convenience of three starting attempts. If initial starts fail, a 'starter failure alarm' alerts and exits the starting state. Impressively, time to rated load startup ranges between 5-10-15 seconds, depending on unit capacity.
(3) Emergency Manual Direct Start Function: In the event of self-controlled device failure, manually engage the emergency direct start function for uninterrupted operation.
2. Automatic Operation: Upon receiving a valid signal fire, the diesel fire pump will autonomously commence operation. Should the pump fail to start due to fire pump motor interruptions or phase failures, it seamlessly transitions back to electric pump mode once power returns or issues resolve.
3. Automatic Shutdown: Witness automatic cessation of the diesel fire-fighting pump, which elegantly delays and shuts down when the fire signal dissipates, showcasing superior intelligence.
4. Battery Self-Charge Function: Ensuring Dependability: The battery autonomously recharges via the diesel engine's mains power, guaranteeing an uninterrupted start every time.
5. Comprehensive Indicating System: Gain insights with indicators for readiness to start, manual and automatic starts, operational status, shutdown, battery charging, speeding alerts, lubrication oil pressure, turbocharger oil pressure, engine lubricating oil temperature, cooling system water temperature, battery voltage, fuel level, and regular maintenance checks.
6. Robust Alarm and Protection System: Enjoy peace of mind with a system that alerts for starting failures, overspeed, lubricant oil pressure anomalies, turbocharger oil pressure issues, cooling water and lubricating oil temperature alerts, charging device malfunctions, and battery voltage concerns.
7. Exceptional Display Systems: Access real-time data on engine oil pressure, engine speed, battery charge current, and charging voltage for an informed operational overview.
8. Direct-Coupled Excellence: Featuring a high-flexibility coupling, the diesel engine and water pump merge seamlessly on a common channel base. This compact, robust structure ensures optimal performance, minimal failure and vibration, and straightforward on-site installation.
9. Unmatched 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 emergency scenarios.
10. Adjustable Flow and Working Pressure: With diesel pumps equipped with mechanical or electronic speed governors, adjust engine speed to align pump flow and head with actual data seamlessly, meeting your specific needs.
11. Pre-Heating Device for Water Temperature: Featuring an AC220V cooling water preheating device, this unit ensures optimal performance even in environments below 5ºC.
12. Double Battery Circuit: In case of one battery failure, another automatically activates, ensuring continuous operation.
13. Maintenance-Free Battery: Experience convenience with a maintenance-free battery that eliminates the frequent need for supplemental fluid.
14. Automatic Timing Inspection Test: In the realm of fire systems, which predominantly remain in a vigilant standby mode, our unit excels by autonomously conducting comprehensive device testing to ensure standby readiness, coupled with the provision of timely warnings to preempt any issues.
Note: The aforementioned functions are modular and can be tailored to meet individual user requirements. Furthermore, we are adept at offering bespoke designs that cater to specific and unique needs, ensuring the ultimate in customization and satisfaction.
