CORROSION PROTECTION SYSTEM AND PUMP DEVICE WITH THE SAME

摘要

The life of a sacrificial anode for use in a pump device, such as a seawater pump, is extended, thus extending the life of a corrosion protection system of the seawater pump device. A pump device includes corrosion system including: a measurement unit located at a portion of a column pipe to be immersed into seawater; and a temperature control device located at an installation site of the pump device. In this corrosion protection system, a sacrificial anode electrically conductive with the column pipe and capable of being controlled in temperature is attached through a heating/cooling unit and a thermal conduction sheet to the column pipe. The temperature control device is configured to control, based on the temperature of the sacrificial anode measured by the measurement unit, the temperature of the sacrificial anode using the heating/cooling unit attached through the thermal conduction sheet to the sacrificial anode.
