METHOD OF ULTRASONIC MACHINING AND INSTALLATION FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B08B3/12 

FIELD: technological processes.

SUBSTANCE: method consists in immersing the end surface of the rod concentrator in a liquid and excitation of longitudinal oscillations in it. A concentrator with a variable internal profile is used as the core concentrator. The cleaned burner device is fixed vertically at the end of the core concentrator. The passive overlay, piezoceramic transducer, rod concentrator and the cleaned burner device of the gas pumping unit fixed on it form a single oscillating system, the total length of which is nλ, where λ is the ultrasonic wavelength, n = 3, 4, 5. The cleaning liquid is pumped through the channels and openings of the cleaned burner device of the gascompressor unit in a closed loop.

EFFECT: improved contamination of internal and external surfaces, as well as channels and openings of gas-discharge tubes of burner devices of gascompressor units.
