Abstract

PURPOSE: To remove heat trans mission due to radiation from feed liquid at a high temperature and to reduce temperatures of casings, bearings, windings, etc. by a method wherein anticorrosive and lustrous plating like chrome plating, silver plating, etc. is performed on the inner surface of a pump casing.
CONSTITUTION: Item 10 shows an anticorrosive and lustrous plating like chrome plating, silver plating, etc. given to the inner surface in contact with feed liquid in a pump casing 1. When the temperature of the feed liquid is high, radiant heat from the feed liquid is reflected, transmission heat only in transmitted from feed liquid at a high temperature to the pump casing 1, heat transmission due to radiation disappears and so the temperature of the pump casing 1 can be made lower than what is not plated in such a manner. Thus, the temperature can be reduced in a bearing 11 and a winding 12 affected by the heat transmission from the pump casing 1 and those lives can be elongated.
