Description

one

The invention relates to the ultrasonic cleaning of parts, in particular parts of fuel equipment.

Ultrasonic cleaning devices are known for parts with a limited volume of washing solution and Rod Type 1 and 2 emitters.

However, the volume of the cleaning solution in the ultrasonic cleaning chamber is large, which leads to a vain dissipation in it of the energy of ultrasonic vibrations. In addition, the volume of solution in the chamber of ultrasonic cleaning changes as the parts being cleaned move through it, which violates the stability of the transducers.

The closest to the proposed invention is a device containing a transporting element with vertical enclosures forming technological positions, an object table located under the transporting element, in which a channel for supplying working fluid, located above the transporting element, has a distribution element with a window made above the transmission channel working fluid, and a rod-type waveguide with a radiating plate.

placed in the distribution box window 3.

To reduce the level fluctuation of the solution, the cleaning chamber contains an additional volume of solution with a level significantly

exceeding its Pett-less value. The additional volume of the solution causes a waste of part of the energy of ultrasonic vibrations, which reduces the cleaning efficiency. Leaps in the level of the solution violate the stable operation of the radiator.

Rapid filling of the cassette cell and rapid discharge of the solution cause foaming of the solution, which leads to a decrease in the density of the solution and, consequently, to an increase in the cleaning time.

The aim of the invention is to stabilize the cleaning process by frightening the reduction of the working volume of the solution, eliminating fluctuations in the level of the solution in the cleaning chamber, reducing the flow rate of the solution when filling in the ultrasonic position.

cleaning and reducing the flow rate of the solution when draining and the associated elimination of foaming.
