Problems solved by technology

[0004] Although the above technical solution solves the lubricating oil supply problem, after the aero-engine is assembled, it is necessary to test the loss of the lubricating oil system to meet the design requirements. Since the lubricating oil returned from the engine will contain air and gas, it will be milky, and if it is recirculated into The engine will not be fully lubricated, which will increase the wear and tear of the engine and reduce the service life

Abstract

The invention discloses a transfer device for an airplane lubricating oil system. The transfer device comprises a box body, an oil supply pipe arranged on the box body, an oil return pipe arranged onthe box body, an oil-gas separation device arranged in the box body and an exhaust pipe arranged on the box body, wherein the oil supply pipe penetrates through the box body and communicates with thebox body, the oil return pipe penetrates through the box body and communicates with the upper part of the box body, the exhaust pipe penetrates through the box body and communicates with the outside of the box body, the oil-gas separation device is arranged at the upper part of the box body, and a gas outlet of the oil-gas separation device communicates with the exhaust pipe. According to the device, a centrifugal oil-gas separator is arranged in the box body, fuel gas and air in lubricating oil can be separated, meanwhile, the separated air and fuel gas are discharged out of the box body, secondary mixing of the air, the fuel gas and the lubricating oil is avoided, a compartment with a heating function is arranged in the box body, the lubricating oil is rapidly heated when an engine is started, severe fluctuation of the lubricating oil due to changes of the attitude of an airplane and the like is prevented, and the box body can be supported in a reinforced mode.

Description

technical field [0001] The invention belongs to the technical field of aviation, and in particular relates to a transfer device for an aircraft lubricating oil system. Background technique [0002] In the lubricating oil system used in aviation turboprop engines, the engine delivers the lubricating oil and sucks back the lubricating oil from the engine to continuously circulate along a closed loop. Friction, less wear, and at the same time take away the heat generated by friction and the inclusions between relative moving surfaces; [0003] The application number is CN201520830237.2, the application date is 2015.10.23, and the utility model patent named "an integrally embedded lubricating oil tank", the specific content is as follows: The utility model discloses an integrally embedded lubricating oil tank, The lubricating oil tank includes an outer wall and an inner wall. The lubricating oil tank is a drum-shaped structure with a through hole in the middle. The shape of th...
