Description

[0001] technical field [0002] The invention relates to an electrolytic processing electrolyte circulating filter system, an electrolyte filtering monitoring method, and an electrolyte component control method, belonging to the technical field of electrolytic processing. Background technique [0003] In the process of electrolytic processing, while the workpiece being processed is corroded and formed, it must be accompanied by a large amount of electrolytic product—electrolytic mud. Usually, the volume of electrolytic mud is 100-200 times larger than the volume of the removed metal, and its composition is mainly hydroxide. Precipitation exists in flocculent form in the electrolyte. If the workpiece to be processed is a carbon-containing metal material, since carbon is the least active element in the electrochemical reaction, insoluble particles are formed during the electrolytic machining process, and there are graphite particles in the electrolytic slime. Carbide in high...

Problems solved by technology

[0008] At present, the automation of the control of the electrolyte components is relatively low in China. Usually, before the process test and industrial production, the pH meter and the density meter are used to monitor the electrolysis. The PH value and conductivity of the liquid are controlled, but the electrolytic processing process lacks strict monitoring and adjustment of the electrolyte components. The German EMAG electrochemical processing electrolyte circulation filtration system has been equipped with an accurate control system for the electrolyte PH value and conductivity. , combined with the self-developed vibration feeding technology, can realize the high-quality and efficient processing of the whole blade disc blade basin, blade back and intake and exhaust edges
