Performance features
1, With three remarkable starting functions:
(1). Manual start function: Seamlessly engage the manual-start function through a smart manual-automatic interlock switch.
(2). Automatic-manual functions: Enjoy three automatic start attempts—if unsuccessful, a 'starter failure alarm' is triggered, and the system exits starting mode. Upon initial success, the transition to rated load occurs within 5-10-15 seconds, depending on unit capacity.
(3). Emergency manual direct start function: In case of self-control device failure, an emergency manual start is readily accessible.
2. Automatic operation: When a valid fire signal is received, the diesel fire pump springs into action, ensuring operation even if the fire pump motor's power supply is interrupted. Once normal power supply resumes, automatic transition to electric pump operation is achieved.
3. Automatic shutdown: The diesel fire-fighting pump efficiently delays and automatically shuts down when the fire signal ceases, ensuring optimal energy conservation.
4. The battery self-charge function: Designed for consistency, the battery automatically charges via the diesel engine's electrical mains, guaranteeing a reliable and smooth start every time.
5. Sophisticated indicating system: This system effectively communicates readiness, start modes, operational status, battery charge, speeding alerts, and various pressure and temperature warnings, ensuring full control and monitoring.
6. Advanced alarm or protection system: Enjoy peace of mind with alarms for start failures, overspeed, lubricant oil pressures, cooling temperatures, charging device issues, and fuel levels, ensuring safety and performance.
7. Comprehensive display systems: Display crucial metrics such as engine oil pressure, engine speed, battery charging current, and voltage, facilitating meticulous monitoring.
8. Direct-coupled: Featuring a high-flexible coupling between the diesel engine and water pump on a common base, this design enhances overall performance, minimizes failure and vibration, and simplifies on-site installation.
9. Superior pressure and flow capacity: Select from IS series single-stage, SOW series double-suction, or SHD series multistage pumps to perfectly suit different fire scenarios, ensuring robust performance.
10. Adjustable flow and pressure: Diesel pumps equipped with mechanical or electronic speed governors adapt engine speed to match pump flow and head with actual demands.
11. Pre-heating device for water temperature: Equipped with an AC220V cooling water preheating device, ensuring optimal operation even at temperatures below 5°C.
12. Double battery circuit: In case of one battery failure, the alternate battery automatically takes over, ensuring uninterrupted operation.
13. Maintenance-free battery: Enjoy the convenience of a battery that requires no frequent supplemental fluid, offering hassle-free operation.
14. Automatic Timing Inspection Test: In the realm of fire systems, which are predominantly in a standby state, our unit excels by autonomously executing device tests to ensure readiness. This includes prompt alerts, ensuring your system is always on guard.
