Abstract
The invention relates to a method for treating the surface of a fan blade, which comprises the following steps of: 1) putting quartz sand with the granularity of 0.3 to 0.5mm into a sand blasting storage tank; 2) connecting a spray gun at an outlet of an air compressor and supplying power to the air compressor by using a generator; 3) starting the generator, controlling the pressure of compressed air of the air compressor to be 0.8Mpa and adjusting the pressure of compressed air generated at a muzzle of the spray gun simultaneously to make the pressure of the sprayed air in a range of 0.5 to 1Mpa; 4) connecting an outlet of the sand blasting storage tank with the air compressor through a pipeline and performing sand blasting on the surface of the fan blade according to the pressure range of the compressed air set in the step 3), wherein a distance between the muzzle of the spray gun and the surface of the fan blade is in a range of 0.4 to 0.5m; and 5) moving the muzzle of the spray gun at a speed of 0.5m/s and keeping the sand blasting direction of a nozzle consistent with the normal direction of a curved surface on the surface of the fan blade so as to complete the sand blasting operation of the surface of the whole fan blade. The method has high generality and can be suitable for various types and sizes of fan blades.
Description
Technical field
The present invention relates to a kind of method for treating surface of fan blade.
Background technology
The fan blade of general large-scale wind driven generator is to adopt glass-reinforced plastic material; To the processing on fan blade surface be lean on artificial with electronic milling tools to the blade processing of polishing; With the roughness of raising blade surface, thereby guarantee the adhesive force that paint is surperficial with glass-reinforced plastic material.In this kind treatment process process, working strength of workers is very big, dust pollution especially severe, and inefficiency, and the quality control difficulty of treatment process is high.
Summary of the invention
To the problems referred to above, the purpose of this invention is to provide a kind of efficient, environmental protection, method for treating surface of fan blade that feasibility is high.
Be to realize above-mentioned purpose, the present invention takes following technical scheme: a kind of method for treating surface of fan blade, and it specifically may further comprise the steps: be that the quartz sand of 0.3～0.5mm is packed in the sandblast storage tank with granularity 1); 2) connect a spray gun in the exit of air compressor, and utilize a generator to supply power to air compressor; 3) starter-generator, the pressure of compressed air of control air compressor, pressure is 0.8MPa, regulates the compressed air pressure that spray gun muzzle place produces simultaneously, makes the atmospheric pressure scope of ejection be: 0.5～1MPa; 4) outlet with the sandblast storage tank is connected with air compressor through pipeline, according to the pressure of compressed air scope of setting in the step 3), sandblast is carried out on the surface of fan blade, the distance range on spray gun muzzle and fan blade surface: 0.4～0.5m; 5) speed with 0.5m/s moves the spray gun muzzle, and the Surface Method on direction and fan blade surface that makes the spout sandblast is to being consistent, to accomplish the sandblast work of whole blower fan blade surface.
In the said step 3), the pressure of compressed air that spray gun muzzle place produces is 0.8MPa.
In the said step 4), the distance on spray gun muzzle and fan blade surface is 0.5m.
The present invention is owing to take above technical scheme; It has the following advantages: 1, because the present invention has utilized compressed air to be power; Make quartz sand form the high velocity jet bundle, carry out blasting treatment with the surface to fan blade, the high velocity jet bundle produces impact and shear action to the surface of fan blade; Make the surface of fan blade obtain different roughness and cleannes; Thereby increased the adhesive force between paint and the fan blade, improved the attractive in appearance and corrosion resistance of fan blade, prolonged the service life of fan blade.2, since through the present invention handle fan blade surface roughness later than the roughness of the blade surface that sprays paint a little more than 0.2～0.3, the surperficial mechanical performance of fan blade is improved, thereby has improved the fatigue resistance of fan blade.3, owing among the present invention the spray gun muzzle is moved on the fan blade surface with the 0.5m/s translational speed; And the direction of spout sandblast as far as possible with the Surface Method on fan blade surface to being consistent; Therefore can further improve the roughness of blade surface, and roughness is more even.4, be the quartz sand of 0.3～0.5mm owing to the present invention has adopted granularity, so environmental pollution (dust) is less, better guarantees the workshop workers'health.5, because the quartz sand loss among the present invention is few, therefore can reduce production costs in a large number.Highly versatile of the present invention goes for the wind electricity blade of various models and size.
The specific embodiment
Carry out detailed description below in conjunction with embodiment to of the present invention.
The present invention utilizes compressed air to be power; Make quartz sand form the high velocity jet bundle; Blasting treatment is carried out on surface to fan blade; The high velocity jet bundle produces the fan blade surface and impacts and shear action, makes the surface of fan blade obtain different roughness and cleannes, and it specifically comprises following operation:
1) selecting granularity is the quartz sand of 0.3～0.5mm, and the quartz sand of choosing is packed in the sandblast storage tank.
2) connect a spray gun in the exit of air compressor, and utilize a generator to supply power to air compressor, above-mentioned spray gun is this area common equipment.
3) starter-generator, the compressed air of control air compressor makes pressure of compressed air be controlled to be 0.8MPa, regulates the pressure of compressed air that spray gun muzzle place produces simultaneously, and the atmospheric pressure scope at muzzle place is: 0.5～1MPa, preferred pressure: 0.8MPa.
4) outlet with the sandblast storage tank is connected with air compressor through pipeline; According to the pressure of compressed air scope of setting in the step 3); Sandblast is carried out on surface to fan blade, the distance range on spray gun muzzle and fan blade surface: 0.4～0.5m, preferred distance: 0.5m.
5) move the spray gun muzzle, spray gun spout translational speed: 0.5m/s, the direction of spout sandblast as far as possible with the Surface Method on fan blade surface to being consistent, to accomplish the sandblast work of whole blower fan blade surface.
Fan blade to utilizing technology of the present invention to accomplish is tested, and draws following result:
Sandblast fan blade surface roughness later, improves the surperficial mechanical performance of fan blade, thereby has improved the fatigue resistance of fan blade a little more than 0.2～0.3 than the roughness of the blade surface that sprays paint.And, can also increase the adhesive force between paint and the fan blade, improve the attractive in appearance and corrosion resistance of fan blade, prolong the service life of fan blade.In addition, through the granularity of adjustment quartz sand, can find the quartz sand that is fit to technological requirement.
