Aeroengine lubrication bearings how to implement? 2020 - 10 - 29 aircraft engine in order to improve working reliability and prolong the service life of mechanical components, will design a lubricating oil system. And now advanced engine USES the improved design of the lubricating oil system, their features include not in pressurization oil pressure regulating valve, with perfect monitoring system, in the return oil pipe containing fine oil filter, the oil - The servo fuel heat exchangers, etc. Traditional engine oil pump into the rear of the lubricating oil system has the pressure regulating valve, which can ensure oil pressure under different engine working at 2. 95 * 10 ^ 5 ~ 3. 53 * 10 ^ 5 pa, regulating the lubricating oil into the oil filter, filter in 50 ~ 80 & mu; m。 High pressure oil filter bypass also has safety valve. When oil filter clogging, increase pressure drop between inlet and outlet, to limit the bypass valve will automatically open, this can ensure the engine is always in a state of lubricating oil to protect. Basic engine adopts the lubricating oil system in the 1980 s. And back to the pump will be equipped with coarse mesh and magnetic plug, to prevent too much of a metal or metal particles into the pump back. Modern engine lubricating oil system, using the improved design of the pressure in the oil pressure regulating valve is not set up, install only the winter too much when you start the engine oil pressure of the pressure limiting valve. Oil pressure of oil increase with the increase of engine speed. In addition to lubricating oil system has perfect monitoring system. Using three kinds of monitoring devices such as CFM56 engine. Including neutralization test flight and maintenance and troubleshooting. This equipment is for pilots and ground member can find problems in a timely manner. 飞机 80 c2 and CFM 56 engine lubricating oil system, such as thermal servo with high-pressure fuel oil, lubricating oil by heating and then flows into the fuel - Lubricating oil in the radiator cooling, which can prevent the regulating mechanism and actuator cylinder in high pressure fuel pipe freezing. Engine lubricating oil system back to the oil pipe has fine oil filter, filter degrees higher than the feed system of fine oil filter. This can ensure the lubrication oil can be back in the tank to clean. To ensure the safety of the whole system. ( In this paper, system network reproduced)
