Function Specifications
The diesel engine fire pump system provides full automation with electric, stabilizing, and diesel backup operation. Upon detecting a pressure drop in the fire pipeline, the system starts automatically, restoring pressure and maintaining operation. If the main electric pump fails, the diesel engine automatically activates to ensure continuous water delivery, preventing fire hazards.
Structure and Principle
The system consists of an automatic stabilizing pump, an electric fire pump, and a diesel fire pump. It maintains pressure between predefined P1 and P2 values by cycling the pump group. When pipeline pressure drops below P1, the system initiates the stabilizing pump; when it reaches P2, it stops automatically. In case of power failure, the diesel unit takes over automatically and restores system pressure within seconds.
Engine Cooling Methods
The diesel engine cooling system adopts a forced circulation water-cooling design with water tank, fan, thermostat, and radiator. Optional open-cycle cooling can be supplied for field operation. Users can select air–water combined cooling mode for extended applications.
