High-temperature motor pump

摘要

There is disclosed a high temperature pump which is compact in size, reasonable in manufacturing cost and capable of stable pumping operation. The high-temperature motor pump comprises a pump portion for pumping a liquid, a motor portion integrated with the pump portion for driving the same, a rotatable shaft for transmitting a rotation of the motor portion to the pump portion. A magnetic bearing is provided within the motor portion for supporting one end of the rotatable shaft by actively controlling a position thereof in a radial direction. A hydrostatic bearing is provided within the pump portion for supporting the other end of the rotational shaft in a radial direction by using a hydrostatic pressure of a portion of the liquid pumped by the pump portion. <IMAGE>
