Abstract


Bolt hydraulic tensioner is ideal equipment for bolt fastening and disassembly. Compared with traditional method, it has incomparable advantages. Bolt hydraulic tensioner has been widely used in wind power, nuclear power, aerospace, steel, petrochemical and other major fields. In this paper, two methods of calibrating the hydraulic stretcher are proposed, and the problems that should be paid attention to in the process of calibrating the stretcher are analyzed in detail, it can be used for reference in the calibration of hydraulic stretcher.
