        Where is the oil filled by the 200kw generator set consumed?

        The 200kw generator set is very common in our daily life, and its application field is very wide. Since the development of my country's industrial economy, life and production can not be separated from power everywhere, and the power will be shut down. The existence of the unit is to provide a double guarantee for life and production. It is often equipped with mobile trailers and silent devices, which are used in industrial and agricultural production. As we all know, one of the maintenance methods of the unit is to fill the engine oil. Then some customers asked, where did the oil filled by the unit go?

        The answer is that part of it went to the combustion chamber due to the "channeling oil" and was burned or formed carbon deposits, and the other part leaked out from the tight seal.

        The oil of 200kw generator set generally enters the combustion chamber through the gap between the piston ring and the ring groove, and the gap between the valve and the duct. The direct cause of its intrusion is that the initial piston ring near the top dead center due to its rapid decline in speed, will throw the oil attached to it into the combustion chamber. Therefore, the matching clearance between the piston ring and the piston, the oil scraping capacity and capacity of the piston ring, the pressure in the combustion chamber and the oil viscosity are all closely related to the oil consumption.

        In terms of operating conditions, the viscosity of the oil used is too low, the engine speed and water temperature are too high, the deformation of the cylinder liner exceeds the limit, the number of starts and stops is frequent, the engine parts wear too much, the oil level is too high, etc. will increase the oil consumption.

        The deviation of the piston caused by the bending of the connecting rod and the failure of the shaping tolerance of the body (the mark is along both ends of the axis of the piston pin hole, and the wear marks of the cylinder liner and the piston appear on the piston land and piston skirt on the other side) It is also an important reason for the increase in oil consumption.

        The 200kw generator set uses a twist ring and a combined oil ring, which has a distinct effect on reducing the oil consumption. Especially the combined oil ring is light in weight, and the three-piece structure has no pump oil effect. It is compliant itself and has good adaptability to the cylinder wall. Keep the side of the oil ring firmly against the ring groove.
