An aero-engine on-wing cleaning machine

Abstract

The invention discloses an aero-engine on-wing cleaning machine. The bracket provided can enable the injection assembly to have the position adjustment capabilities of vertical lifting, circumferential rotation and horizontal telescopicity to meet the needs of real-time adjustment of the injection angle of the nozzle during the cleaning process; through electromagnetic The valve is used to adjust the number of spray nozzles, which has the effect of saving cleaning liquid. The shield is set to prevent the sprayed liquid from being splashed back, and also prevents the nozzle from colliding with the engine wall; the overpressure shunt port set on the nozzle can Over-pressure protection is provided for the peak pressure of the liquid output, which improves the stability and reliability of the injection assembly; the liquid collection device is opened and closed by pulling the subframe, and the first collection belt on the automatic rewinding drum and the manual rewinding drum Together with the second collection belt, the liquid after cleaning can be completely collected and controlled through the integrated electrical control cabinet. At the same time, the main frame can pull the sub-frame to achieve flexible transfer, which is easy to use, fast 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
