Aero-engine on-wing cleaning machine

Abstract

The invention discloses an aero-engine on-wing cleaning machine. A spray assembly is made to have the position adjusting capacity of vertical lifting, circumferential rotating and horizontal expanding by means of a support, and the requirement for adjusting the spray angle of nozzles in real time in the cleaning process is met; the number of spraying nozzles is adjusted through solenoid valves, and the function of saving cleaning liquid is achieved; a protective cover is arranged, so that sprayed liquid is prevented from splashing reversely, and the nozzles can be prevented from impacting the wall of an aero-engine; an overpressure diversion port formed in each nozzle is capable of conducting overpressure protection on liquid output peak value pressure, and the stability and reliability of the spray assembly are improved; a liquid collecting device is opened or closed by pulling an auxiliary frame, liquid obtained after cleaning can be completely collected by a first collecting belt and a second collecting belt on an automatic take-up cylinder and a manual take-up cylinder, an electric control cabinet is used for integrated control, and meanwhile the auxiliary frame is capable of being pulled by a main frame to be transferred flexibly; the aero-engine on-wing cleaning machine has the advantages of being convenient to use, high in speed and efficient.

Description

technical field [0001] The invention relates to the technical field of aviation ground special equipment, in particular to an aero-engine on-wing cleaning machine. Background technique [0002] A gas turbine engine installed as an aircraft engine includes a compressor that compresses ambient air, a combustor that burns fuel with the compressed air, and a turbine that drives the compressor. The expanding combustion gases drive the turbines and also result in the thrust used to propel the aircraft. Air ventilators for jet engines consume large amounts of air. The air contains foreign particles in the form of aerosols or larger particles, which then enter the engine with the airflow. Most particles will follow the gas path through the engine and exit with the exhaust. However, some particles have properties that cause sticking to components in the engine gas path. The accumulation of particles alters the aerodynamic properties of the engine and more specifically reduces eng...

Problems solved by technology

Third: the position of the nozzle is adjustable and the height is adjustable, so it is applicable to the cleaning of different types of aircraft engine blades; but the aeroengine cleaning injection system of this technical solution exists: 1) the injection system exists independently and needs to rely on other The cleaning liquid supply system, liquid collection device and other equipment can only work together, which does not meet the needs of integrated and integrated technological development; 2) Both the level adjustment device and the height adjustment device need to be adjusted manually, and the mutual adjustment of cleaning between different models During the conversion process, manual adjustment takes a lot of operating time, and the nozzle adjustment device is also adjusted before spray cleaning, which cannot meet the needs of real-time adjustment function during the cleaning process; convenient
