METHOD OF HYDRAULIC CAVITATION CLEANING OF BLANK CAVITIES IN ARTICLES

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to hydraulic cavitation methods of cleaning hard-to-access surfaces. Proposed method of cleaning hollow cavities of articles 1 comprises creating fluid jets in flooded cavity and exciting cavitation in said jets. It comprises also using said jets to act on surface to be cleaned and exporting the material of broken deposits by fluid flow. Deposit material is broken in articles with blank cavities by periodic and sequential variation of counter pressure in flooded cavity. Counter pressure variation is started from high counter pressure to zero in preset time interval. Note here that maximum erosion destruction of material occurs. ^ EFFECT: higher efficiency of cleaning and safety. ^ 4 cl, 3 dwg
