MOTOR JET APPARATUS FOR PREVENTING AND REMOVING SCALE USING POTENTIAL DIFFERENCE

摘要

A motor jet apparatus is provided to prevent scale in a pipe by using magnesium ion which is ionized by the potential difference between an outlet pipe and a sacrificial anode made of magnesium alloy. A motor jet apparatus comprises a sacrificial anode and an upper casing(30). The sacrificial anode is arranged in an underwater motor(1) or an outlet pipe(10) of a pump, and equipped with a plurality of partitions having the same radial shapes as the inner diameter of the outlet pipe. The partitions have stream line-shaped or linear grooves for ease of fluid flow. Ionization occurs by the potential difference between the sacrificial anode and the outlet pipe during fluid flow, and formation of scale on a pipe(40) is prevented by the ionization. The upper casing is coupled between the outlet pipe and the pipe, and has a stream line shape so that fluid flowing among the partitions is combined.
