Description
Technical field
The invention belongs to the processing method of generator shaft, particularly a kind of processing method of wind driven generation set main shaft erosional surface.
Background technology
General wind driven generation set main shaft specification is all determined according to the power of the wind power generating set complete machine of coupling, and the main shaft specification being such as assemblied in 2.0MW wind power generating set complete machine is just 2.0MW wind driven generation set main shaft.
From mode of production classification, wind driven generation set main shaft is divided into forging axle and casting two kinds, axle.From products application classification, wind driven generation set main shaft is mainly divided into double-fed asynchronous variable speed model wind generator set main shaft and permanent magnet direct-drive wind-force generating set main shaft.
Along with the manufacturing fast development of global wind power generating set complete machine, the technical merit as the wind driven generation set main shaft manufacturing of one of core component constantly promotes, and main manifestations is:
(1) progressively break original industry boundary, and overall absorption merges the new technology of each specialty of steel-making, forging, heat treatment, machining and anticorrosive coating, define relatively advanced wind driven generation set main shaft specialized fabrication technology.
(2) computer simulation and Computer Control Technology obtain overall application.
(3) various advanced detection means is widely used.
(4) specification is tending towards maximizing.Along with the maximization of domestic and international wind power generating set complete machine develops, associated supporting wind driven generation set main shaft is also tending towards maximizing.Mainstream model domestic is at present 2.0-3.0MW, and land maximum type is 5.0MW, following 3-5, and the market share of domestic Large Copacity wind power generating set will be increasing, until replace little megawatt wind driven generator group.
But because generator shaft trends towards maximizing, cause the process-cycle long, transportation more complicated, in-site installation needs the longer time.Like this in processing, transport, installation process, likely cause surface corrosion, have impact on installation accuracy.
Because the required precision of main shaft itself is high, the method for polishing is not easily adopted to eliminate rust.
Summary of the invention
The object of the present invention is to provide a kind of processing method of wind driven generation set main shaft erosional surface, there is construction simple, eliminate rust effective, do not affect precision and the surface smoothness of main shaft.
The present invention is realized by following measures
A processing method for wind driven generation set main shaft erosional surface, is characterized in that adopting following steps
(1) main shaft soft cloth wiped clean;
(2) by bottom surface adhesive layer heat fused, at even application bottom surface, main shaft surface adhesive layer, a small amount of principle is repeatedly adopted during spraying bottom surface adhesive layer, the bottom surface adhesive layer of 1-2mm on even application, solidification 20-30 minute; Described bottom surface adhesive is by weight: PVC:30-40, dioctyl phthalate: 30-40, gelatine: 5-8, zinc stearate 2-5, lanolin 2-5; Above-mentioned PVC adopts emulsion method polymerization PVC, K value 63, the degree of polymerization 900;
(3) after the solidification of bottom surface adhesive layer, then brush the surface adhesive layer of 1-2mm, be wound around 3-5 layer glass fiber tape, solidification; Described surface adhesive layer is by weight: polyurethane resin 30-40, epoxy resin 5-8, titanium dioxide 5-8, talcum powder 5-8;
(4) before installing, carefully glass fiber tape is cut off, and surface adhesive layer and bottom surface adhesive layer are peeled off, then wipe examination totally with soft cloth, can install.
Processing method described in the invention described above, its preferred version is: described bottom surface adhesive is by weight: PVC:35, dioctyl phthalate: 35, gelatine: 6, zinc stearate 4, lanolin 4.
Main innovate point of the present invention is, adopts the bottom surface adhesive after fusing to spray to main shaft surface, the iron rust on surface can being bonded, when not affecting surface smoothness, being removed by the rust on surface.Bottom surface adhesive adopts low polymerization degree emulsion method polymerization PVC, can improve permeability and the mobility of adhesive to greatest extent.Add gelatine in the adhesive of bottom surface, can be combined by the iron better in iron rust, add a certain amount of zinc stearate and lanolin, can promote that the composition in adhesive enters the micropore on main shaft surface, improve its permeability, remove iron rust more up hill and dale.
Second innovative point of the present invention is, adds surface cement, to improve bonding strength further, ensures thoroughly to remove iron rust, meanwhile, and can easily by bottom surface binder removal.
The invention has the beneficial effects as follows, can site operation, construction is simple, eliminates rust effective, does not affect precision and the surface smoothness of main shaft.
