Specialists from the Design Bureau-1 of the Kingisepp Machine-Building Plant (KMZ) have presented a lever hydraulic wrench designed for tightening and loosening nuts of the flanged connection of the main circulation pump unit (MCPU) of nuclear power plants. This tool is part of a nutrunner for the group connection of the MCPU.
The hydraulic wrench consists of a torque wrench, a column, and a spacer. The column is installed on the end face of the MCPU flange, fixed to the adjacent nuts, and the spacer is placed on the nut to be tightened.
After aligning the splines of the spacer, torque wrench, and column, the nut is tightened with a torque of 13200 N*m by rotating the inner wheel of the wrench.
