Surface pressure measuring device of the ring-shaped gland packing, and surface pressure measurement method

摘要

PROBLEM TO BE SOLVED: To provide a surface pressure measuring device for gland packing, capable of measuring distribution of inside surface pressure activating to the outside of a shaft directly in one setting and also capable of measuring the distribution of inside surface pressure in an axial direction, with identical conditions as the laminated use of the ring-shaped gland packing.;SOLUTION: The surface pressure measuring device for the gland packing of ring shape comprises an axis formed by laminating multiple sheets of disk-like load cells; a stuffing box formed so as to surround the outside surface of the axis; and a packing stuffing, means arranged on the stuffing box, for pressing the gland packing of multiple ring shape laminated between the axial part and the stuffing box in an axial direction. The disk-like load cells are arranged with strain detection sensors in the prescribed positions.;COPYRIGHT: (C)2005,JPO&NCIPI
