Overall supply type high-pressure cylinder facilitating measurement of dynamic and static positions and method

The invention relates to an overall supply type high-pressure cylinder facilitating measurement of dynamic and static positions and a method. The overall supply type high-pressure cylinder comprises a cylindrical cylinder body, wherein a rotor is arranged in the cylinder body, end steam seals are arranged on the end faces of two ends of the cylinder body correspondingly; a first positioning block and two second positioning blocks are arranged at the end steam seal of each end; each first positioning block is installed on the upper portion of the corresponding end steam seal; the side face, away from the corresponding end steam seal, of each first positioning block forms a first positioning face; each first positioning face is perpendicular to a horizontal symmetry face in the rotor; the second positioning blocks are installed on the left side and the right side of the end steam seals correspondingly; second positioning faces are formed on the side faces, close to the center of the rotor, of the second positio
