Problems solved by technology

The existing rotor misalignment detection devices cannot fully detect the corresponding misalignment forms. For example, some detection devices can only detect angle misalignment faults, while some detection devices can only detect parallel misalignment and deflection angle misalignment. failure
Moreover, none of the existing misalignment detection devices can detect the quantitative value of the corresponding misalignment form
Moreover, the existing misalignment detection devices are all fixed devices, which cannot flexibly adapt to the scene for misalignment detection, which increases the difficulty of detection

Abstract

A mobile rotor system misalignment multi-dimensional quantitative detection device, including a base, a height lifting component, a horizontal moving component, a horizontal measuring ruler, a vertical measuring ruler and an analyzer, the base and the height lifting component are symmetrically arranged, and the lower end of the height lifting component It is connected with the base, the horizontal moving component is connected with the height lifting component and moves in the height direction with the height lifting component, the horizontal measuring ruler is rotatably installed on the horizontal moving component, the vertical measuring ruler is slidingly installed on the horizontal measuring ruler, and the analyzer on the outside of the base. A mobile rotor system misalignment multi-dimensional quantitative detection method adopts the above-mentioned mobile rotor system misalignment multi-dimensional quantitative detection device. The invention has the advantages of being able to detect the misalignment of various rotor systems, detecting the specific numerical value of the corresponding misalignment, being convenient to move, and the like. The invention belongs to the technical field of rotor machinery.

Description

technical field [0001] The invention belongs to the technical field of rotor machinery, and in particular relates to a mobile rotor system misalignment multi-dimensional quantitative detection device and method. Background technique [0002] The rotor system is a key component of important equipment such as aero-engines, steam turbines, helicopters, and fan engines. Affected by factors such as manufacturing, installation errors, and wear during use, two adjacent rotors are often in a state of misalignment, parallel misalignment, or comprehensive misalignment of parallel deflection angles, such as figure 1 , figure 2 As shown; slight misalignment will cause increased vibration of the equipment, accelerate wear and fatigue damage, and reduce the operating life of the equipment. Serious misalignment will directly lead to machine crash and death. According to foreign statistics, the vibration and misalignment related faults of the whole aircraft engine account for 50%-60% of ...
