Abstract
The invention belongs to the technical field of mechanical design, and particularly relates to an anti-corrosion device for a seawater circulating pump. The device comprises an impeller, a sacrificial anode ring, a stud A, a nut A, a protective cover cap and a pump shaft; a circular step is arranged on the upper surface of the impeller, the annular sacrificial anode is arranged on the step in a sleeving mode, the pump shaft is connected with the impeller through the stud A and the nut A, and the protective cover cap is installed on the top of the stud A. The device is simple in structure and convenient to install, the corrosion problem of the pump shaft and the impeller of the seawater circulating pump is effectively solved by adopting the measure of additionally installing the sacrificial anode ring, the exposed part of a fastening bolt is coated with anti-corrosion grease, the protective cover cap is additionally installed and sealed, the bolt and seawater are prevented from being in contact, and the problems that the fastening bolt of the impeller is corroded and difficult to disassemble and the like are effectively solved.
