Abstract

Purpose. Hydrodynamic calculation of flow of the electrolyte in the interelectrode gap of electro-technical complex for the dimensional electrochemical machining

Design/methodology/approach. The most significant scientific and applied results, conclusions and recommendations are as follows: for the first time invited to the dependence of the total resistance of the interelectrode gap from electrical, hydraulic and geometric parameters. Set the U-shaped dependence of the resistance of the working current, which leads to its instability, that is, for the first time theoretically explained by the frequent appearance of the regime of a short circuit when electrochemical processing; for the first time considered the inductance of the interelectrode gap, which helped to create a more accurate mathematical model of the complex.

Рroposed the mathematical model of the power circuit of electro-technical complex for electrochemical treatment of metals and alloys, which allows you to: correct in theory to calculate the values of the operating current; theoretically explain the property of self-regulation interelectrode gap (the presence of the derivative in the law regulation).

Findings. The essence of the carried out researches is in the theoretical explanation of the properties of self-regulation interelectrode gap and the possibility of a regime of a short circuit, as well as in the theoretical calculation of the operating current of the complex depending on its electrical, geometric and hydraulic parameters.

Originality/value. Рroposed the mathematical model of the power circuit of electro-technical complex for electrochemical treatment of metals and alloys, which allows you to: correct in theory to calculate the values of the operating current; theoretically explain the property of self-regulation interelectrode gap (the presence of the derivative in the law regulation)
