Embodiment 1
[0014] This embodiment provides a method for axially and radially positioning the rotor during the transportation of the gas turbine, which is characterized in that: the method for axially and radially positioning the rotor during the transportation of the gas turbine: first, as shown in the diagram of the positioning scheme for the front part of the rotor As shown in the figure, there are four plugging mounting seats along the circumference of the gas turbine front support shell assembly. Remove the plugging caps on the plugging mounting seats, position the four radially blocking caps, and install the plugging caps on the plugging mounting seats. First, make the end face of the blocking cover contact with the inner hole of the first-stage wheel disc of the gas turbine and press it tightly, and then screw the screw 30° to ensure that the screw is fully pre-tightened, so as to ensure the radial positioning of the front of the rotor. to the amount of movement;
[0015] Then, as ...

Disclosed is an axial and radial positioning method for a rotator in gas turbine transporting process. The method includes firstly arranging four seal cap mounting seats around the circumference of a front supporting shell component of a gas turbine, mounting seal caps on the seal cap mounting seats, allowing end faces of the seal caps to contact with and tightly pressed on a first-stage disc inner hole of the gas turbine, then screwing screws at 30 degrees so as to guarantee that no radial displacement exists in the front of the rotator; then, utilizing a gas turbine positioning ring as a positioning tool, mounting long top wires in, and guaranteeing that no radial displacement exists on the end faces; finally, screwing three long screws, guaranteeing that the end faces and the end face of the gas turbine positioning ring are contacted axially and pressed tightly and no axial displacement exists. The method has the advantages that reasonable parts of mounted parts are utilized to perform rotator positioning, production of positioning and tooling equipment is omitted, repeated disassembling process is further omitted, and safety of a bearing during transportation can be protected properly, and cost for producing the positioning and tooling equipment and time and labor cost for repeated disassembling are saved.
Description
