摘要:
Displacement sensors (19) are configured so as to be capable of measuring relative displacement along the axial direction of an outer ring-fixing member (17), which is for fixing the outer ring (16) of one end of a bearing (6), or a casing (18) with respect to an inner ring-fixing member (20), which is for fixing the inner ring (13) of the one end of the bearing (6), or the rotor (5). A load-calculating unit calculates the thrust load acting on the rotor (5) by multiplying the relative displacement measured by the displacement sensors (19) by a conversion coefficient.

A protecting tube deterioration detecting apparatus applies a predetermined electric current to a measurement target thermocouple with protecting tube for a predetermined time, calculates a temperature rise amount of the thermocouple, and determines, when the calculated temperature rise amount exceeds a predetermined threshold, that the protecting tube is deteriorated.

A mixing rotor includes: a rotor shaft portion that includes a cooling passageway formed therein, and a mixing blade portion that is formed in an outer circumferential portion of the rotor shaft portion, wherein each of the long blades of the mixing blade portion includes a land portion as an end surface of the long blade facing a radially outside of the mixing rotor, a length of each of the long blades in the axis direction is set to be 0.6 times or more as large as a length of the mixing blade portion in the axis direction, a biting angle of each of the long blades is set to an angle equal to or smaller than 31°, and a center angle with respect to a land width as a width of the land portion in the cross-section of each of the long blades orthogonal to the axis direction is set to an angle equal to or larger than 7°.

摘要:
The relative displacement in the axial direction between an outer ring fixing member (17) or casing (18) and an inner ring fixing member (20) or rotor (5) is determined, said outer ring fixing member (17) being a member for affixing an outer ring (16) of a bearing (6) on one side, and said inner ring fixing member (20) being a member for affixing an inner ring (13) of the bearing (6) on the one end side. When calculating a thrust load acting on the rotor (5) by multiplying the determined relative displacement by a conversion coefficient, an axial force measuring bolt (26) is used as a tightening bolt for affixing the bearing (6) on the one end side, said axial force measuring bolt (26) enabling measurement of a load acting in the axial direction. The axial force measured by the axial force measuring bolt (26) and the relative displacement during measurement of the axial force are used to calibrate the conversion coefficient.
