Wind power generation
Wind power equipment is generally perennial in the harsh outdoor environment such as the ocean, the Gobi, plateau and so on. Strong corrosion, extreme weather conditions are always in the test of the life of the cylinder. Any one of the cylinder failure will bring a huge maintenance costs, so the life of the cylinder with a very high demand. Wantong hydraulic can be based on customer data, using finite element technology to optimize the structure of the cylinder to ensure that the cylinder has enough fatigue life. Using a special support and sealing technology through the cylinder, with a very small gap, using world-renowned brand seal, we can ensure in the cylinder has a good sealing performance under that the conditions. At the same time, the stability of the piston rod of the cylinder is verified by the professional finite element software, which ensures that the cylinder is not deformed and leak-free under the harsh working conditions.
High-quality materials with high strength and low temperature impact performance, to ensure that the hydraulic cylinder will not fail under the case of extreme low temperature,Advanced CNC machining equipment to ensure the accuracy of parts processing, advanced boring equipment to ensure a straightness of 0.02 mm / 500 mm or more, under normal circumstances, straightness guaranteed at 0.05 mm / 200mm, we do the industry standard of 6.25 times; roughness to Ra0.1, under normal circumstances, the roughness of the R00.4, 4 times beyond the industry standard, and the hole nickel-cadmium alloy process ensure the cylinder finish and?long service life
At present, the cylinders produced by same industry can not reach 10 years life of the customer requirements. The wind power generators operating above the megawatt-class wind turbines are used to improve the power generation efficiency and power quality of the wind turbines, so that the wind turbines can get the best performance under various operating conditions, Reduce the impact of wind on wind power generators. The hydraulic pitch system has the advantages of small volume, light weight, good dynamic response, large torque, no variable speed mechanism and mature technology. It can realize the rotation of the blade 90 °, so that the fan can start or stop quickly. From the installation of the fan, It has been in use, with the wind speed and wind direction of the ever-changing, at any time to adjust, in this case hydraulic cylinder must meet the 10-year service life, the middle term does not allow damage.
