The electrochemical protection testing system consists of an experiment auxiliary subsystem, an electrochemical testing subsystem, and a reference electrode fixing and transmission subsystem, wherein the experiment auxiliary subsystem comprises a testing water tank, a device fixing frame and a supporter; the electrochemical testing subsystem comprises an electrochemical working station, a No.1 computer and a reference electrode; the reference electrode fixing and transmission subsystem comprises an electrode axial fixing device, an electrode circumferential fixing device and a transmission device; the electrode axial fixing device comprises a slide block, an electrode fixing frame, a largefixed ring and a small fixed ring; the electrode circumferential fixing device comprises a guide ring and a plug; the transmission device comprises a slide guide rail, a transmission screw rod, a linear bearing, a transmission screw nut, a bearing, a bearing block, an elastic coupling, a servo motor and a No.2 computer. The electrochemical protection testing system has the advantages that the relative potential of the surface of a cylindrical underwater vehicle can be accurately measured, the electrochemical corrosion degree of the measured vehicle can be determined, and the corrosion weak point and other information can be acknowledged.

Description

technical field [0001] The invention belongs to the field of mechanical design, and more specifically relates to a cylindrical marine equipment electrochemical protection test system. Background technique [0002] Marine corrosion has become a key problem to be solved in marine equipment and marine engineering. With the gradual understanding and exploration of the ocean, marine equipment and marine engineering have been put into practical application. It has become a topic that countries all over the world pay attention to. Among many corrosion research and anti-corrosion measures, electrochemical anti-corrosion is a very effective and reliable solution. However, the traditional sacrificial anode protection method only uses the principle of the original battery to select the corresponding anode, and determines the amount and fixed position of the anode based on experience. This will cause three problems. One is that the material selection of the anode is not suitable, and ...

Problems solved by technology

However, the traditional sacrificial anode protection method only uses the principle of the original battery to select the corresponding anode, and determines the amount and fixed position of the anode based on experience.

This will cause three problems. One is that the material selection of the anode is not suitable, and it may not be able to achieve a real protective effect; but that the amount of anode is too much or too little to cause over-protection and insufficient protection; the third is to determine only by experience The location of the anode may make some parts of the entire protected device overprotected and some places underprotected, so that the electrochemical protection of the sacrificial anode cannot play its due effect
