Function Specifications
The diesel engine fire pump operates automatically with backup electric and stabilizing pumps. When pressure drops below the preset level (P1), the system automatically starts to restore water pressure. Once the main power returns or pressure stabilizes, the diesel unit stops automatically after a delay. This ensures uninterrupted firefighting readiness and full automation for emergency conditions.
Structure and Principle
The system consists of a stabilizing pump, electric pump, and diesel fire pump (standby). It maintains pressure between P1 and P2 by automatically cycling between pumps. In case of power loss, the diesel unit starts automatically to maintain supply. When power resumes, it switches back to normal mode with minimal downtime, ensuring constant water delivery.
Engine Cooling Methods
The cooling system uses a forced circulating water-cooling structure with water tank, fan, thermostat, and heat exchanger. If required, an open-cycle cooling configuration can be provided for field operations. Combined air-water cooling options are also available upon request.
