Cleaning equipment for clean aeroengine case

Abstract

The invention discloses cleaning equipment for a clean aeroengine case. The cleaning equipment comprises a cleaning chamber, a cleaning oil storage and transportation facility chamber and an oil injection gun, wherein a cleaning table for mounting a to-be-cleaned case is arranged in the cleaning chamber; an oil injection gun stretching window is formed in the chamber wall; an oil storage tank; an oil storage tank, an oil pump, a pressure-stabilizing overflow unit and an oil filter are arranged in the cleaning oil storage and transportation facility chamber; the inlet of the oil pump is connected with the interior of the oil storage tank through a connecting pipe, and the oil pump is driven by a motor; the pressure-stabilizing overflow unit and the oil filter are sequentially arranged on a pipeline behind the oil pump; and the oil injection gun is connected with the outlet end of the oil filter through a flexible connecting pipe. According to the cleaning equipment disclosed by the invention, the surface of the aeroengine case can be cleaned at high cleaning degree, metal debris remaining in the case can be cleaned, and the harm of the metal debris produced in the engine test and operation process is avoided. Moreover, because lubricating oil serves as a cleaning medium, the cleaning equipment disclosed by the invention has the advantage that the problem that cavitation corrosion is produced on the part surface is solved compared with ultrasonic cleaning.

Description

technical field [0001] The invention relates to the technical field of aero-engine manufacturing, in particular to a device for cleaning the engine casing before the aero-engine is assembled. Background technique [0002] Aircraft engine casings usually need to be cleaned after machine finishing and before assembly. The cleaning of the casings in the prior art is mainly to clean the dirt on the surface of the casings. The cleaning methods are ultrasonic cleaning, or using Ultrasonic mechanical cleaning equipment cleans the casing. However, for the mechanically finished casing, the accuracy of the assembly part and the surface finish are very high. If long-term ultrasonic cleaning is used, it will cause cavitation corrosion on the surface of the parts, which is not conducive to its later maintenance and maintenance. use. In addition, the aero-engine casing is the main part of the aero-engine, and the casing structure is complex. There are many positioning installation struc...
