In the presented article, the experience of the Samara State Technical University on the use of low-frequency cavitation in the technology of washing machine parts and devices is considered.
Based on the results of research conducted by STC "Reliability" of SamSTU, low-frequency cavitation washing plants and technologies have been developed and tested at enterprises with the use of industrial water without heating and detergents as a washing liquid: installation at JSC "Aviaagregat" for cleaning aluminum pipes of the chassis of aircraft when immersed in a cavitating liquid; installation for washing the packages of filter elements of oil systems of gas turbine aircraft engines; installations for jet-cavitation washing of products of complex shape and large dimensions - carrier rocket tanks at JSC "RCC" Progress ", large-sized axle box bearings of railway cars at JSC "Samara Bearing Plant" and in the wagon depots of Kinel and Samara stations of the Kuibyshev Railway, etc. without making constructive changes and reconfiguring their staffing scheme.
Developments have shown that washing parts with low-frequency cavitation is not only more productive than other known methods of washing, but also allows cleaning parts of a complex configuration with internal cavities and blind channels, successfully removing solid abrasive particles, carved in the surface of parts during grinding, etc.
The low-frequency cavitation units for cleaning parts by immersion in washing liquid and jet washing, presented in the article, provide a high level of quality and washing performance at a relatively low cost, which is confirmed by their industrial approbation.
