Abstract
The invention relates to a method for eliminating swing standard exceeding faults of a fan guider of an aero-engine. The method includes the steps that when swing of the fan guider exceeds the standard in the test run of the aero-engine, a main pump adjuster is used for adjusting the rotating speed of the engine, and fault eliminating of the main pump adjust of the aero-engine is conducted; a rotating speed analog signal is sent to an electronic adjuster, the rotating speed of the engine is adjusted through the electronic adjuster, and fault eliminating of the electronic adjuster is conducted; and fault eliminating of an electrical circuit of the engine and fault eliminating of a rotating speed sensor of the engine are conducted until swing standard exceeding faults of the fan guider of the engine are eliminated. The method can be used for eliminating test run faults of various types of engines, the fault eliminating time in an engine plant is effectively shortened, swing faults of the fan guider of the engine are efficiently eliminated, engine cost is reduced, the utilization rate of the engine is increased, and fuel cost is saved.
