Structural Analysis of Diesel Engine Fire Pump Unit
The diesel engine fire pump unit has a compact structure, complete functions, stable and reliable performance, and is an indispensable and important equipment in the fire protection system.
The structural analysis of the diesel engine fire pump unit is as follows:
1. Core components
Diesel engine: As a power source, the diesel engine usually adopts high-quality products of domestic or internationally renowned brands, such as Cummins, Wuxi Power Machinery Factory, etc., which generates powerful power by burning diesel to drive the entire unit to work.
Fire pump: As an output device of the diesel engine, the fire pump converts the power of the diesel engine into the flow power of the liquid. It is the core component of the unit. Through the rotation of the impeller, the liquid obtains energy, thereby completing the task of fire water supply.
2. Auxiliary system
Cooling system: used to cool the diesel engine to prevent it from overheating. It is usually composed of a cooling water tank, a fan, etc., forming a closed cycle to ensure that the diesel engine works in an efficient and stable state.
Lubrication system: Provide lubricating oil for the moving parts of the diesel engine, reduce wear and extend the service life of the unit.
Fuel system: used to store and transport diesel for diesel engine combustion. Ensure that the unit can start quickly and run continuously when needed.
3. Control system
PLC or diesel engine control system: realize automatic control of diesel engine pump unit to ensure safe and reliable operation of the unit. The unit is equipped with multiple protection functions, such as overspeed, low oil pressure, high water temperature, etc., to ensure that the unit can respond quickly and take measures under abnormal conditions.
4. Other parts
Chassis: Support the mass of the entire unit, ensure that the unit is in a horizontal state, and absorb vibration.
Coupling: High elastic coupling or diaphragm coupling directly connects the diesel engine and fire pump to ensure the stability and reliability of power transmission.
