Reciprocating type marine corrosion-resistant internal combustion engine flywheel spraying dryer

Technical Field

The invention relates to the technical field of flywheels of marine internal combustion engines, in particular to a reciprocating type flywheel spraying dryer of a marine corrosion-resistant internal combustion engine.

Background

Internal combustion engines are a type of heat engine that converts the chemical energy of a fuel into mechanical energy. The general realization mode is that fuel and air are mixed and combusted to generate heat energy, the gas is heated and expanded, and the heat energy is converted into mechanical energy through a mechanical device to do work outwards. Internal combustion engines are widely used, and the engines of automobiles, ships, airplanes, rockets and the like are basically internal combustion engines, and the most common examples of the internal combustion engines are gasoline engines and diesel engines for vehicles. The combustion gas of the internal combustion engine is also a working medium, for example, in a gasoline engine, the gas after the combustion of the gasoline directly pushes a piston to do work. In contrast, a heat engine in which fuel is not used as a working medium is called an external combustion engine, and the working medium of a steam engine, for example, is not fuel.

The flywheel is a large disc-shaped part of an engine at the rear end of a crankshaft, has large rotational inertia and has the following functions: part of energy of the working stroke of the engine is stored to overcome the resistance of other strokes and ensure that the crankshaft rotates uniformly; the starter is provided with a gear ring meshed with the starter, so that the engine can be started conveniently. In an internal combustion engine, a flywheel has three main functions: the three strokes of exhaust, suction and compression of the internal combustion engine are completed mainly by the inertia of a flywheel; in the working stroke, the flywheel stores the energy, and in the other three strokes, the flywheel consumes the stored energy; thirdly, the rotation of the crankshaft is relatively uniform due to the inertia of the flywheel.

Because the flywheel basically works outdoors, the flywheel can also work in a severe environment under partial environment, for example, a ship engine flywheel needs to work underwater for a long time, and in order to ensure the working performance of a main body of the flywheel, the flywheel is required to have moisture resistance and corrosion resistance.
