Description

Technical Field

[0002] At present, during the repair process of domestic low-altitude aircraft engine casings and other components, the main methods used to remove the surface paint coating are manual grinding, sandblasting, chemical reagent immersion and dissolution, etc.

[0003] For example, a protective tool for high-pressure water removal of coatings on complex annular parts with announcement number CN206184884U comprises an annular part, a metal protective ring 1 and a metal protective ring 2. The inner surface of the metal protective ring 1 is affixed with a layer of elastic protective filler 1, the metal protective ring 1 is attached to the lower end of the annular part, the inner surface of the metal protective ring 2 is affixed with a layer of elastic protective filler 2, the metal protective ring 2 is attached to the upper end of the annular part, a soft gasket is installed between the metal protective ring 2 and the annular part, and the soft gasket is interference-fitted with the metal protective ring 2. By using the protective tool, the annular part is protected, which prevents the peeling high-hardness coating particles from scratching the non-coated area of ​​the part when the high-pressure water is used to remove the coating, thereby saving time. Subsequent grinding and repair process, however, when removing the paint coating on the engine casing, since the casing is usually cylindrical, the linearly adjustable position nozzle is difficult to flexibly adapt to the outer surface of the casing for flushing and cleaning, which reduces the flushing and removal effect of high-pressure water on the casing paint coating. The cleaning effect is not high, the scope of application is small, and the existing manual grinding and sandblasting method is easy to damage the part matrix, has low efficiency, and high processing cost; the chemical reagent immersion and dissolution method is harmful to the operators and will also pollute the environment. The ultra-high pressure water jet cleaning has very strict requirements on water due to the high pressure. The water must be softened and then filtered with high purity before use. The nozzle is also required to be very hard and wear-resistant, which increases the cost of use.

[0004] Therefore, a high-pressure pulse water jet paint coating removal device is proposed to solve the above-mentioned problems. Summary of the Invention

The vacuum bubbles are ejected with the high-speed water jet beam and rupture near the rigid solid surface, generating microjets and shock waves, which have a high peak impact force and a strong cavitation damage effect on the impacted object.
