Embodiment 1
[0017] A dry ice cleaning method for the surface of an aero-engine component, the specific steps of which are as follows:
[0018] (1) Prepare the cleaning medium: prepare an appropriate amount of dry ice as the cleaning medium;
[0019] (2) Adjust the air pressure of the equipment: adjust the air supply pressure of the dry ice blasting equipment to keep it between 0.7-0.8MPA;
[0020] (3) Adjust the ice output rate of the equipment: adjust the ice output rate of the dry ice cleaning setting to 1KG / MIN;
[0021] (4) Distance: Adjust so that the distance between the nozzle of the dry ice spray gun and the body is between 30-50CM;
[0022] (5) Vertical: The spraying work needs to make the nozzle of the dry ice spraying nozzle perpendicular to the body;
[0023] (6) Cleaning time: Gently move the nozzle of the dry ice spray gun during work so that the dry ice is evenly sprayed onto the body, and the residence time at each position shall not exceed 5S.
[0024] The spray cleani...

[0026] A dry ice cleaning method for the surface of an aero-engine component, the specific steps of which are as follows:
[0027] (1) Prepare the cleaning medium: prepare an appropriate amount of dry ice as the cleaning medium;
[0028] (2) Adjust the air pressure of the equipment: adjust the air supply pressure of the dry ice blasting equipment to keep it at 0.6MPA;
[0029] (3) Adjust the ice output rate of the equipment: adjust the ice output rate of the dry ice cleaning setting to 0.7KG / MIN;
[0030] (4) Distance: Adjust to keep the distance between the nozzle of the dry ice spray gun and the attached parts between 100-110CM;
[0031] (5) Vertical: The spraying work needs to make the nozzle of the dry ice spraying nozzle perpendicular to the attached parts;
[0032] (6) Cleaning time: Gently move the nozzle of the dry ice spray nozzle during work so that the dry ice can be evenly sprayed onto the attached parts, and the residence time at each position shall not exceed 5...
Embodiment 3
[0035] A dry ice cleaning method for the surface of an aero-engine component, the specific steps of which are as follows:
[0036] (1) Prepare the cleaning medium: prepare an appropriate amount of dry ice as the cleaning medium;
[0037] (2) Adjust the air pressure of the equipment: adjust the air supply pressure of the dry ice blasting equipment to keep it at 0.5MPA;
[0038] (3) Adjust the ice output rate of the equipment: adjust the ice output rate of the dry ice cleaning setting to 0.5KG / MIN;
[0039] (4) Distance: Adjust to keep the distance between the dry ice spray nozzle and the cable between 120-130CM;
[0040] (5) Vertical: The spraying work needs to make the nozzle of the dry ice spraying nozzle perpendicular to the cable;
[0041] (6) Cleaning time: Gently move the nozzle of the dry ice spray gun during work so that the dry ice is evenly sprayed onto the cable, and the dwell time at each position shall not exceed 5S.
