Performance Features
1. Featuring three impeccable starting functions:
(1). Manual Start Function: Achieve manual start effortlessly with manual-automatic interlock through an intuitive switch;
(2). Automatic-Manual Functions: Offering up to three starting attempts. In case of unsuccessful initiations after three tries, it emits a 'starter failure alarm' and automatically ceases its starting state. The transition to rated load occurs within 5-10-15 seconds (depending on unit capacity) after a successful start.
(3). Emergency Manual Direct Start Function: Immediate manual direct start capability ensures operation during self-controlled device failures.
2. Automatic Operation: Upon receiving a valid fire signal, the diesel fire pump springs into action, automatically starting when the electric pump motor's power supply system encounters interruptions or failures. It seamlessly transitions back to the electric pump once normal power resumes or the electric pumps function properly.
3. Automatic Shutdown: The diesel fire-fighting pump intelligently delays and initiates automatic shutdown when the fire signal is no longer present.
4. Battery Self-Charge Function: Ensures uninterrupted operation by automatically charging the battery through the diesel engine's electrical mains power.
5. Comprehensive Indicating System: Monitors ready-to-start status, manual start, automatic start, unit operation, shutdown, battery charging, speeding, low lubrication oil pressure, low turbocharger oil pressure, low engine lubrication oil temperature, high cooling system water temperature, low battery voltage, low fuel level, and regular inspections.
6. Advanced Alarm and Protection System: Equipped to alert or protect against starting failures after three attempts, overspeed, low lubricant oil pressure, low 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. State-of-the-art Display Systems: Provides real-time insights into engine oil pressure, engine speed, battery charge current, and battery charging voltage, ensuring optimal operation.
8. Direct-Coupled Design: The diesel engine and water pump are seamlessly connected using a high-flexible coupling on a shared channel base, offering a compact structure, enhanced overall performance, reduced failure and vibration, and ease of on-site installation.
9. Powerful High Pressure and Large Flow Capacity: Tailored to meet diverse fire scenario requirements, choosing from the IS series single-stage single-suction, SOW series single-stage double-suction, or SHD series segmental multistage pumps.
10. Adjustable Flow and Working Pressure: Equipped with mechanical or electronic speed governors, the diesel pumps offer adjustable speed, allowing flow and head alignment with actual data requirements.
11. Water Temperature Pre-Heating Device: Featuring an AC220V cooling water pre-heating device, this unit ensures optimal operation even in environments with temperatures below 5 ºC.
12. Dual Battery Circuit: Guarantees uninterrupted operation by automatically switching to a secondary battery when one set fails.
13. Maintenance-Free Battery: Designed to eliminate the frequent need for supplemental fluid, offering hassle-free operation.
14. Automatic Timing Inspection Test: Typically residing in standby mode, our fire system is ingeniously designed to autonomously conduct device testing, ensuring its readiness at all times. It provides an impeccable stand-by condition assessment and issues timely alerts for any discrepancies.
Note: Tailor your experience by selecting from a variety of available functions to meet your unique requirements. Shanghai Semhai Pump Co., Ltd. is delighted to offer a bespoke design service, customizing solutions to perfectly align with your specific demands.
