Description
Technical field:
The present invention relates to a kind of cutting working method and isolated plant of rotor.
Background technology:
Along with the prosperity growth of international and domestic sea transport industry, the maintenance task of boats and ships is more and more heavier, and is also more and more higher to the requirement of Ship's Repair technical merit; In the turbine rotor maintenance work, the key of finding the maintenance of exhaust-driven turbo-charger exhaust-gas turbo charger is the maintenance of turbine rotor, the difficult point of its maintenance is: volume is big, weight is big, the processing of sealing gland ring is yielding, sealing gland. spindle nose. the waste gas blade is the shape machined into greatly, the diesel engine turbine rotor sealing gland of now having a talk. the cutting of spindle nose and the grinding of blade.
(ton) peculiar to vessel diesel engine turbine rotor is to be made of parts such as impeller inducer, compression impellor and waste gas impellers.Its operation principle is: the waste gas that diesel engine is discharged when work, enter booster, and drive the blade of rotor waste gas end, fresh air is squeezed in the rotation of drive compression impellor, improves efficiency of combustion, reduces oil consumption, increase the defeated turnout of diesel engine, thus improve boats and ships operation power, reduce cost.
It is heavy diesel fuel that marine main controllable advances diesel engine normally used, and the EGT that the work burning is discharged is very high, and has some impurity.If waste gas seals in the bearing oil pocket, cause oil to worsen, thereby reduce lubricant effect, even cause damage of bearings, in case damage of bearings will cause very big economic loss.In order to prevent that waste gas from sealing in bearing portion, during design, on turbine rotor, be provided with air seal set, sealing gland ring thickness 0.4mm, the sealing gland ring exceeds axial plane 5mm.In long-term maintenance work, find that waste gas end sealing gland weares and teares easily, when sealing gland ring its external diameter that weares and teares reduces, just can not seal the waste gas of waste gas end, must change sealing gland, the new sealing gland outside dimension after the replacing this moment, overgauge 3-4mm needs to carry out metalworking after assembling.
Turbine rotor sealing gland in decades. the renovation technique of spindle nose (always quoting the traditions of the past processing method): 1, remove compression impellor, insulated wall, waste gas impeller; 2, change the sealing gland ring, 3, sealing gland ring to renewing. the diameter of spindle nose carries out machining to given size; 4, waste gas impeller, insulated wall, compression impellor are installed on the turbine rotor axle.If just can not on large-scale lathe, not cut after not removing compression impellor and middle insulated wall, and general enterprise is not equipped with big heavy machine tool.When removing impeller, earlier insulated wall is fixed on the waste gas end with specific purpose tool, again one ton of multiple rotor is stood up, make and calm the anger end vertically downward, utilize oxy-acetylene flame to aim at the face that the tightens up heating of impeller (aluminium) then, artificial rotary rotor is heated evenly impeller, endoporus expands, thereby impeller is unloaded from rotor.Temperature can not be too high during heating, high the hole that tightens up of compression impellor enlarged, and cause compression impellor to scrap, and temperature is low can to cause compression impellor to dismantle, and the control temperature (measures with the distinct temperature table) about 120 degree.Some impeller of rotor is worked under the long term high temperature adverse circumstances and to be difficult to dismounting, need repeatedly expand with heat and contract with cold, and could dismantle (though some impeller of rotor is dismantled, resilient is not finally also scrapped).Rotor in the processing stirs, and all operation of the dismounting of impeller, insulated wall is all very loaded down with trivial details.
