PREHEATING METHOD OF NON-COOLED ELECTROMAGNETIC PUMP FOR LIQUID METAL

Title:

PREHEATING METHOD OF NON-COOLED ELECTROMAGNETIC PUMP FOR LIQUID METAL

Document Type and Number:

Japanese Patent JP2004048894

Kind Code:

A

Abstract:

To provide a preheating method of a non-cooled electromagnetic pump for liquid metal, for maintaining the healthiness of the electromagnetic pump in preheating for charging the liquid metal, and attaining high safety and efficiency.

This preheating method of the non-cooled electromagnetic pump for liquid metal has a duct forming a liquid metal passage; an electromagnetic coil; an iron core; a support structure for supporting the iron core; and a casing for sealing the electromagnetic coil, the iron core, and the support structure. In preheating the electromagnetic pump to charge a liquid metal, since the temperature rise rate at the time of preheating the duct, the electromagnetic coil, the iron core, the support structure, and the casing is set at ≤ 20 °C per hour, the temperature differences between the duct and the casing, and between the duct and the support structure can be restrained, thus preventing breakage to the support structure.
