METHOD FOR CONTROL OF STABILITY IMPROVEMENT IN CAVITATOR OPERATION Russian patent published in 2014 - IPC F24J3/00 

FIELD: electricity.

SUBSTANCE: invention is referred to the field of electric engineering and operation of systems with asynchronous electric motor and frequency control, in particular to control of rotation speed and prevention of critical operation modes. Technical result of the method lies in that reliability of the cavitator is improved; its stable operation is maintained by means of operation mode correction when the detected sign proves potential stalling with change in the electric motor rotation speed. The method for control of stability improvement in cavitator operation includes liquid passing in a gap between the rotor and stator and subsequent conversion of the received energy into thermal energy, control by the heating process. The claimed method for control of the cavitator operation modes is based on the analysis of higher harmonics ratio in the electric mains, its comparing with the threshold value and shaping of the control signal for frequency control unit which controls the rotation speed of the electric motor.

EFFECT: control method allows reaching maximum efficiency for activation of process liquids for the purpose of their use in different processes of chemical production such as dilution, heat generation, and synthesis.
