In the reciprocating piston internal combustion engine, compressors and pumps and other machinery within the cylinder block along the cylinder axis of the mechanical parts. Pistons are disc-shaped, cylindrical and cylindrical three kinds of forms. In the internal combustion engine, the engine piston in the high temperature and high pressure gas driven by the work. In compressors and pumps, the piston exerts pressure on the fluid in the cylinder under external forces to cause fluid flow and increase its pressure. In the hydraulic cylinder, the piston in the pressure of the oil under the action. The closed end of the piston is subjected to the pressure of the working fluid and forms a combustion chamber or compression volume with the cylinder head and cylinder wall. The piston is fitted with a piston ring or a gum seal to prevent fluid leakage. Engine piston can be cast iron, forged steel, cast steel or aluminum alloy and other materials.
The contact pressure between the piston ring and the cylinder liner and the sliding speed are very high, so there is a need for adequate lubrication. Leakage can damage the oil film, in today's large diesel engine, even more so. Therefore, in order to make the diesel engine work steadily, a good seal is very important. The sealing effect of a group of piston rings (which are generally grouped) can be treated as a labyrinth seal. At the interface, the side and the circumference can produce leakage across the piston ring. The most important leak is due to thermal deformation caused by some deformation can be automatically corrected by the role of heat; other deformation is caused by the instability of the diesel engine work. The small defect on the contact surface can also be corrected by the gas to press the piston ring against its contact surface. The magnitude of the force produced by the corrective gas depends primarily on the magnitude of the pressure drop produced by a single piston ring in a set of piston rings. Which in turn depends on the instantaneous leakage area between a group of piston rings.
A variety of changes in pressure distribution can lead to stability of the diesel engine or not. The seal of the circumferential surface of the piston ring can be improved by pre-correcting the shape of the piston ring. A simple tool can be used to determine the correct shape of the piston ring by measuring the local radius of curvature. Most of the contents of this report, due to the use of wear in the practice, manufacturing defects, etc. may have been recognized by most people. Wear can correct some minor defects. So enough to run is very important, the use of a slight wear will also make the diesel engine work stabilized. Rotating the engine piston about its axis also improves its operation.
