Networks of water moter inlet for scale removal for water pipes

摘要

PURPOSE: A suction port net for a submersible motor is provided to remove rust from a pipe by using magnesium and to prevent rust and scale from being created on the pipe by using an ionization tendency. CONSTITUTION: A suction port net is installed in a suction port of a submersible motor. The suction port is made of at least one selected from the group consisting of iron, copper, brass, and zinc, which have a low ionization tendency. The suction port net is made of at least one selected from the group consisting of magnesium, aluminum and zinc, which have an ionization tendency greater than the ionization tendency of materials of the suction port and the submersible motor. The suction port net includes 10-90 weight percent of magnesium and 10-90 weight percent of zinc.
