Characteristics of wind power fasteners |
| Update:
2011-3-8 |
| Wind power fasteners have a series of characteristics in technology: high strength, high precision, high grade, wind turbine service to harsh conditions, effects of perennial withstand heat and cold and extreme temperature, erosion under high temperature, low temperature, high power, the highest reached 3 MW, speed difference. Fasteners subjected to axial tensile load, shear load or bending loads and impact loads; or also bear the above several load, and in the environment of the medium under the effect of wind power fasteners will cause delayed fracture of bolts, and under the condition of high temperature caused by material creep. From the current high intensity of wind power in the production of fasteners, to ensure that 10 years, 20 years of service life, the road is long, yet to be tested. The wind power fastener enterprises only through a comprehensive quality control, to ensure the mechanical properties, fatigue limit, fasteners and fasteners, recommended enterprises to expand ideas, not only to improve the quality level of their products, but also to understand the wind turbine in any special requirements. Automatic drilling machine is composed of two pin high speed stepless frequency spindle, two automatic vibration send pin device, two pressure pin head, two circuit board clamping device, two eccentric adjustment device park board size, a size of center distance of baffle unit. The maximum hole diameter is Phi 3.15, wind power fasteners for the circuit board thickness 10 mm, drilled a pin automatically, and can also be bored. Automatic pin machine is drilled in printed circuit board manufacturing, CNC drilling, positioning machining holes, special equipment and fitted with the positioning pin. Safety pin coupling structure. The screw is the modular structure, and the corresponding cylinder pin screw element corresponding to the accuracy of three equal intermittent slotted screw. The pin is mainly used for making nail bed plate, both sides can also print, save time and improve efficiency; pin application: nail bed plate, both sides can also print, save time and improve efficiency; pin features: Material: characteristics of imports of copper, durable. Any specifications can be produced in a timely manner. Use a flat positioning pin fastening. Selection of special steel, wear-resistant, durable; high precision machining tolerances, +0.00/-0.01mm; the nail head with a round head and chamfer two, for the customer to choose. |
