Description

Technical field [0001] The invention relates to a device for electroplating repair on the inner surface of a mud pump cylinder liner, in particular to an anode rotary vibration device for electroplating repair on the inner surface of a mud pump cylinder liner. Background technique [0002] Drilling mud pump is a kind of reciprocating plunger pump. As one of the most important process equipment for oil drilling operations, the drilling mud pump is subjected to large load torque, high pressure erosion of the mud fluid and its corrosion and hardness during the operation process. Due to particle wear and other effects, the cylinder liners of drilling mud pumps often suffer from wear, corrosion and deformation, which have a serious impact on the smooth progress of oilfield drilling operations, and also greatly increase the cost of oilfield development. According to statistics, my country’s drilling crew consumes more than 100 million yuan in cylinder liners each year. It can be seen ...
