Description
Technical field
The utility model relates to a kind of field turning device, is specifically related to a kind of turbine LP rotors excitation slip ring field turning device.
Background technology
In actual production, generating unit excitation slip ring and carbon brush contact site produce strong spark and cause gap bridge busbar blow and be forced to stop.There is serious groove mark in excitation slip ring surface on inspection, the maximum point degree of depth reaches about 1mm, surface roughness Ra less than 12.5, present situation is seriously overproof compared with designing requirement, and surface occurs that serious groove mark causes carbon brush and the loose contact of excitation slip ring to be the main causes producing spark and can not generate electricity.Excitation slip ring surface must process again for this reason, generator amature need be pulled down and be transported to producer and carry out turnery processing by repair method routinely, such repairing approximately needs about one month time that Turbo-generator Set can be made to reach normal operation, maintenance procedures is complicated, maintenance time is long, affects turbine LP rotors and normally runs.
Utility model content
The utility model is large for solving existing turbine LP rotors excitation slip ring surface roughness, when needing to carry out turnery processing, maintenance procedures is complicated, maintenance time is long, and affect turbine LP rotors normally to run, thus add the problem of maintenance cost, and then a kind of turbine LP rotors excitation slip ring field turning device is proposed.
The utility model is the technical scheme taked that solves the problem: turbine LP rotors excitation slip ring field turning device comprises base, adjustment plate, advance and retreat knife rest and abrasive machine, base is disc, base upper surface is radially processed with mounting groove, adjustment plate is arranged in mounting groove, and adjustment plate can slidably reciprocate along the length direction of mounting groove, the upper surface setting concordant with the upper surface of base of adjustment plate, advance and retreat knife rest is arranged on the upper surface of adjustment plate, and the length direction of advance and retreat knife rest vertically to be arranged with the length direction of adjustment plate, abrasive machine is arranged on one end of advance and retreat knife rest, the length of abrasive machine is 300mm, the axle center of the grinding wheel on abrasive machine and the axis parallel of excitation slip ring are arranged.
The beneficial effects of the utility model are: the utility model structure is simple, traditional excitation slip ring is needed the situation delivering to producer's repairing turning after dismantling, the situation of turning repairing is carried out at the scene of changing into, moving left and right of advance and retreat knife rest can be realized by the adjustment plate that base is arranged, advance and retreat knife rest can move forward and backward, and the total length of abrasive machine is shortened at 300mm, because working space effective between steam turbine and generator is within 400mm × 600mm, so make truning fixture just have the activity space of 100mm at left and right directions, and during turning, steam turbine can operate, keep in repair easy, fast, cost saving, time between overhauls(TBO) is short, maintenance cost is reduced about 99.9%.
Accompanying drawing explanation
