Do you know the working principle of diesel engine water pump? Today, we will explain the working principle of a diesel engine water pump from four aspects: the definition of a diesel engine, the basic structure of a diesel engine, the working principle of a diesel engine, and the working principle of a diesel engine water pump.
1. Definition of diesel engine
A diesel engine is a machine that converts the thermal energy generated by fuel combustion into mechanical energy. To complete the entire process of energy conversion, a corresponding conversion mechanism and system must be in place. Although there are various types of diesel engines and their specific structures are not exactly the same, whether it is a single cylinder marine engine or a multi cylinder diesel engine, their basic structure is the same.
2. The basic structure of diesel engines
The basic structure of a diesel engine includes: crank connecting rod mechanism, valve distribution mechanism, transmission mechanism, fuel supply system, lubrication system, cooling system, starting system, and intake and exhaust system. The good coordination of these systems and institutions is crucial for diesel engines to generate power and output power externally.
In the basic structural composition of a diesel engine, the crank connecting rod mechanism, valve distribution mechanism, and fuel supply system are the three basic parts that work together to complete the working cycle of the diesel engine and achieve energy conversion. The quality of the three technical states and the correctness of their coordination during use have a decisive impact on the performance of diesel engines. The lubrication system and cooling system are auxiliary systems for diesel engines and are essential components for their long-term normal operation. If the lubrication or cooling system is not working properly, the diesel engine will malfunction and cannot function properly.
From this, it can be seen that during the use of a diesel engine, the above parts must be fully valued, and no part can be ignored. Otherwise, the normal operation of the diesel engine will not be guaranteed, and it may even cause serious damage to the diesel engine.
3. The working principle of diesel engines
The working principle of a diesel engine is that during operation, it draws air into a closed cylinder and is compressed to a higher degree due to the upward movement of the piston. At the end of compression, the cylinder can reach a high temperature of 500-700 ℃ and 3.0-5 High pressure of OMPa. Then, the fuel is sprayed into the high-temperature air in the combustion chamber of the cylinder in a mist form, mixed with high-temperature and high-pressure air to form a combustible mixture, which automatically ignites and burns.
4. Working principle of diesel engine water pump
The energy released during combustion (peak value exceeding 13 The OMPa explosive force acts on the top surface of the piston, pushing it and converting it into rotating mechanical work through the connecting rod and crankshaft. Therefore, a diesel engine is actually a machine that converts the chemical energy of fuel into mechanical energy and outputs power to the diesel engine water pump. The diesel engine water pump is powered by the diesel engine, so it is called a diesel engine water pump.
Diesel engines are widely used in various water pump products, such as chemical pumps, sewage pumps, high-pressure water pumps, hand-held fire pumps, self priming pumps, multi-stage centrifugal pumps, and double suction centrifugal pumps, all of which can be equipped with diesel engines as power.
The above four points provide a detailed introduction to the working principle of diesel engine water pumps, hoping to be helpful to you.
