Abstract
The invention provides a test device and test method for lubricating oil cut-off of an aero-engine afterburner fuel regulator. By transforming a test device for an afterburner fuel regulator and adding a temperature measurement device on the afterburner fuel regulator, the invention achieves the purpose of monitoring whether a bearing of the afterburner fuel regulator works abnormally, solves the problem that an original test device for the afterburner fuel regulator does not meet lubricating oil cut-off test conditions and the problem of how to monitoring the working status of the afterburner fuel regulator after the lubricating oil cut-off, verifies whether the lubricating oil cut-off of the afterburner fuel regulator would cause damage to the bearing or an abnormal increase in temperature of a housing, and finds out the working time of the afterburner fuel regulator when the housing does not break after the lubricating oil cut-off. The test method facilitates the quick analysis of causes of failure of the bearing of the afterburner fuel regulator and the increase in the temperature of the housing.
Description
【Technical field】 [0001] The invention belongs to the field of aero-engines, and relates to an afterburner fuel regulator of an aero-engine, in particular to a test device and a test method for oil cut-off of an afterburner fuel regulator of an aero-engine. 【Background technique】 [0002] The afterburner fuel regulator is an important part of the aero-engine. It provides fuel for the afterburner of the engine, and automatically adjusts the amount of fuel supply as the flight status changes, so as to maintain the best fuel-gas ratio in the afterburner, which provides the best fuel for the aircraft to take off, Provides extra thrust during climbs and combat. If a fault occurs, it will cause serious accidents such as engine and aircraft catching fire and crashing. There is no fuel cut-off test in the traditional afterburner adjustment. If the assessment is not carried out, various problems will occur, which will lead to potential safety hazards of the engine. [0003] Afterbu...
