DEVICE FOR MODULATION OF APPLICATION PROCESSES OF GALVANIC COATINGS

摘要

A device for modulation of application processes of galvanic coatings consists of galvanic bath, cathode, anode, which made as threedisconnected among themselves sections, each from which has cell of dielectric material and connected to positive terminal of corresponding regulated electric power supply, demountable terminal of electric power supply is connected to cathode, three circuits, each of which consists of consistently connected gauge of current density, processing block of gauge signals, regulation block of current density and regulated electric power supply, computer, determination block of average density of current, three analog-digital changers, three measurement gauges of thickness of coatings, determination block of average thickness of coating, concentration gauges of electrolyte components, comparison block, batchers, two analog-digital changers, timer, two commutators, at thatoutputs of gauges of thickness measurement are connected to corresponding inputsof determination block of average thickness of coating through first commutator, at that first commutator is connected to the one input of computer through analog-digital changer, at that computer its first output is connected to the second input of commutator, outputs of first commutator are connected also to inputs of analog-digital changer, and outputs of concentration gauges of constituent electrolytes are connected to inputs of comparison block, and are connected to other ofinput of computer through analog-digital changer, batchers are connected with output of comparison block, secondinpuof which is connected to second output of computer through analog-digital changer, third output of which is connected to inputs of regulation blocks of density current through analog-digital changer, fourth output is connected to inputs of regulated electric power sources through other commutator, at that thirdinputof computer is connected with gauge of density current through determination block of average density of current and analog-digital changer, fourth inputand fifthoutput of machine are connected with timer. The third commutator and option switch of work is additionally introduced, at that the inputs of commutator are connected to inputs of first commuator and option switch of work, which is connected with computer by the input and other output.
