Embodiment

[0032] A device for grinding and removing carbon deposits on turbine blades with magnetic needles, which includes a cleaning tank 1 for placing cleaning liquid 2 and magnetic needles 3, a cooling circulation system for adjusting the temperature of the cleaning liquid, two permanent magnets 5 for driving magnetic needles 3, two The block permanent magnet 5 is connected with the output end of the motor 4 through a support beam 7 . The specifications of the magnetic needle 3 are: diameter 0.2-1.5mm, length 8-20mm, material is ferromagnetic material containing stainless steel, alloy containing any several elements of iron, cobalt and nickel. This implementation case is mainly aimed at the turbine guide vane of an aircraft engine. The diameter of the air hole is about 1 mm, and the inside of the air hole has a radian. According to the shape of the air hole, it is ensured that the magnetic needle does not enter the interior of the turbine blade. Therefore, the material of the magneti...

Abstract

The invention discloses a method for removing carbon deposition on a turbine blade of an aircraft engine through magnetic needle grinding. The method for removing the carbon deposition on the turbine blade of the aircraft engine through magnetic needle grinding comprises the steps that the turbine blade is soaked in a dissolved cleaning solution, so that the surface of the turbine blade is infiltrated; a magnetic needle is poured into the cleaning solution, the magnetic needle impacts the surface of the turbine blade under a rotating electromagnetic field and rotates forwards and reversely at intervals for cleaning, and the carbon deposition on the surface of the turbine blade is removed; and the turbine blade is taken out after cleaning is completed, the carbon deposition and the cleaning solution attached to the surface of the turbine blade are washed away through a high-pressure water gun, and then the turbine blade is dried. According to the method for removing the carbon deposition on the turbine blade of the aircraft engine through magnetic needle grinding, the carbon deposition of the turbine blade is removed under the condition that a strong oxidant and strong alkali are not used; an abrasive material adopted for magnetic needle grinding is slender, so that the abrasive material cannot enter the turbine blade through heat dissipation holes of the turbine blade; in addition, batch treatment of the turbine blades can be achieved, manual grinding is not needed, and therefore the cleaning efficiency of the carbon deposition of the turbine blades is greatly improved.

Description

technical field [0001] The invention relates to a method for removing carbon deposits on aircraft engine turbine blades by using magnetic needle grinding, and belongs to the technical field of metal material surface treatment. Background technique [0002] During the operation of the aircraft engine, the incomplete combustion of aviation kerosene will form a solid layer of carbon deposits on the turbine blades. The main elements of carbon deposits on the surface of turbine blades are oxygen, silicon, aluminum, calcium, magnesium, nickel, etc. Therefore, carbon deposits are mainly insoluble and insoluble components, and it is very difficult to remove them. During the maintenance of aircraft turbine blades, the existence of carbon deposits will make the flaw detection of turbine blades impossible, and the cracked turbine blades may cause the plane to crash. The long-term accumulation of carbon deposits will also affect the life of the engine. At present, the methods of removi...
