LASER TRACKER PICTURES – HYDRO Apr 29, 2020 Center of rotation of runner measurement on a horizontal unit Measuring stator diameter of a large vertical unit Outer headcover measurement for a vertical unit (off unit) Discharge and Bottom ring measurement with tracker mounted on its side Measuring rotor diameter (in service bay) of vertical unit Discharge and Bottom ring measurement with tracker mounted on its side An unforseen advantage of using the tracker over conventional methods is that large equipment can be lowered into the turbine while still being able to perform measurements Turbine casing profile measurement for a horizontal unit Service Bay Stator measurement with extension rod on vertical unit Discharge ring measurement from a vertical unit with tracker mounted on its side fixed to one of the wicket gates Stator replacement Stator measurement on vertical unit Measuring stay ring with tracker mounted on the stay ring Turbine casing flange measurement on horizontal unit Tracker set up on its side to measure intake gate guides Measuring the stay ring on a vertical unit Measuring benchmarks on a horizontal unit Measuring stator and upper bracket elevations Measuring sole plates with a 0.5" SMR (only small edge was accessible to measure). Measuring a servo motor Laser tracker set up at lower bracket elevation looking down onto the headcover Measuring the embedded flanges for the servo motors.
