Embodiment Construction

[0021] Such as Figure 1-4 As shown, the present invention provides a technical solution: a fault diagnosis device for an aero-engine fuel regulator, including a body 1, the bottom surface of the body 1 is provided with anti-skid grooves 17, and the number of anti-skid grooves 17 is not less than four. The groove 17 strengthens the friction strength between the body 1 and the placement surface, prevents the body 1 from slipping when it is placed vertically, and improves the overall stability of the body 1. The outer surface of the body 1 is fixedly inlaid with a rubber soft cover 18, and the rubber soft The cover 18 and the body 1 are located on the same vertical line, and the friction force between the body 1 and the hands of the staff is strengthened by arranging the soft rubber cover 18, and the hands will not be worn, so as to prevent the hands of the staff from being separated from the body 1, and at the same time The comfort of the body 1 is improved, and the hands of th...

Abstract

The invention discloses a fault diagnosis device for an aero-engine fuel regulator, which relates to the technical field of engine fuel regulators. plate, the upper surface of the sealing plate is placed with a geared motor, the outer surface of the geared motor is covered with a fixed ring, the bottom surface of the fixed ring is fixedly connected with a fixed rod, and the bottom of the fixed rod is connected with the sealing plate. The upper surface is fixedly connected, the top of the deceleration motor is provided with a push cylinder, the outer surface of the push cylinder is provided with a chute, the outer surface of the deceleration motor is fixedly connected with a limit slide bar, and the top end of the limit slide bar Slidingly connected with the chute, the bottom surface of the push cylinder is provided with a threaded hole, the output end of the geared motor is fixedly connected with a threaded rod, and the top of the threaded rod is threadedly connected with the threaded hole. The aircraft engine fuel regulator fault diagnosis equipment has the advantage of adjusting the length of suction.

Description

technical field [0001] The invention relates to the technical field of engine fuel regulators, in particular to an aircraft engine fuel regulator fault diagnosis device. Background technique [0002] The fuel regulator of an aero engine belongs to a mechanical hydraulic system with a complex structure. It is composed of multiple components that are coupled with each other. On the other hand, as the mechanical hydraulic control backup of the aero-engine digital control system, its performance directly affects the working state of the engine, and even affects the safety and reliability of the aircraft. [0003] Once a component in the aeroengine fuel regulation system fails, the function of the entire fuel regulator will be affected. If the failure cannot be eliminated in time, it may cause a major accident. Among these failures, gas diagnostic equipment is relatively rare, and the current Some fuel regulator gas diagnostic equipment still has the problem that the suction len...
