Electroplating device for electroplating outside cylinder body tank

Abstract

The invention discloses an electroplating device for electroplating outside a cylinder body tank. The electroplating device comprises an anode, a flow guide piece and an electroplating environment forming assembly, the anode is installed on the electroplating environment forming assembly, an electroplating environment is formed around the anode, and the flow guide piece is used for guiding electroplating liquid into the electroplating environment and enabling the electroplating liquid to flow into the anode center from the top end of the anode and flow back. The flow guide piece is provided with a plurality of flow distribution holes for electroplating liquid to pass through, and the flow distribution holes are distributed in a circulation interface of the electroplating liquid. The structure that the flow distribution holes are formed in the circulation interface of the electroplating liquid is adopted; large impact is prevented from being formed under the driving of the pump; a stable electroplating environment can be provided in the dynamic electroplating process; the advantages of dynamic electroplating are still achieved, it is guaranteed that positive ions on a plating layerare replaced in real time, indifferent concentrations and stable and uniform flowability are formed, and therefore compactness of the plating layer is well guaranteed, and the electroplating quality is guaranteed.

Description

technical field [0001] The invention relates to a cylinder electroplating device component, in particular to an electroplating device used for electroplating outside a cylinder tank. Background technique [0002] As the main component of the engine, plunger pump, reciprocating compressor and other equipment, the cylinder block is used to form the working space together with the piston and the cylinder head; taking the engine as an example, it forms the combustion chamber and provides the movement trajectory for the piston assembly, thus forming a Power conversion environment. In the process of guiding the piston to reciprocate continuously, the inner wall of the cylinder and the piston rub against each other for a long time and at a high frequency, which reduces the useful power of the cylinder and consumes a part of the energy. In order to solve the above problems, the inner wall is electroplated, and the electroplating layer is used instead of the cylinder liner to solve ...

AI Technical Summary

Problems solved by technology

[0003] Although cyclic electroplating (dynamic electroplating) has the above advantages, the electroplating environment needs to be relatively stable, but the flowing electroplating solution needs power to drive the circulating flow, which will have an adverse impact on the stable electroplating environment, resulting in adverse effects on the electroplating process. affect the final quality of the product
