Rotor Blade

mass manufacture capacity of wind-power dynamo rotor blade with megawatt grade.

 In 2005, by careful technology and market researches, Zhongfu Lianzhong imported manufacture technology and key equipments of large wind-power dynamo rotor blade with grade 1.5MW from Germany, became domestic famous company which first has mass manufacture capacity of wind-power dynamo rotor blade with megawatt grade.     Lianzhong depends on strong technical strength, fast absorbed the imported technology, the manufacture processes are strictly performed according to imported technics and standards, and combined ISO9001 standards, in order to ensure products excellence characters and quality.    LZ1.5MW rotor blade is one of zhongfu lianzhongs leading products, can cooperate with many 1.5MW wind-power dynamos which designed by Aerodyn company, its aerodynamic and high strengthen & light weight structural design etc. all satisfy with overseas similar products standards. LZ1.5MW rotor blades geometrical form let it has excellence aerodynamic capability, can achieve higher wind power catch and using efficiency. LZ1.5MW rotor blade uses vacuum assistance & bag press moulding tools with advanced technical and higher maturity to manufacture, in its structural design, use high capability filling structural with light weight & high strengthen, under ensure blades strengthen and stiffness requests, not only reduce blades weight, but also reduce blades movement noise, fully exhibits composites materials general capabilities advantages.      LZ1.5MW wind-power rotor blade can steadily work between -20 degree and -50 degree, has excellence capabilities to resist environment and weather. High capability paint layer on rotor blades surface can effectively resist wind, sand, rain, snow and salt fogs corrosion, and has well UV prevention and strong temperature change resist capability. LZ1.5 rotor blade installs credible lightning prevention system, can resist lightnings damage for rotor blade. 

LZ1.5MW rotor blade obtained germany GL authority certificate, now has 72 rotor blades which were formally installed and used in world every wind-power field, the first system has already steadily and effectively operated for 6 years, these success cases show LZ1.5MW rotor blades reliability , security and applicability.*Basic parameters*Total length (m):37.5*Maximum string length (m):3.2*Standard weight (kg):5800*Application parameters*Control method:shift and slurry change rules*Rating power (MW):1.5*Application wind field grade:GLIII*Rotor blade diameter (m):77*Rotor blade revolving way :clockwise*Rating revolving speedRPM :17.3 *Rating wind speed (m/s):11*3 seconds cutting wind speed (m/s):35*Rating/urgent lock torque (KNm):1378/2067*Work temperature ():-20--+50Root joint parameters*Bolt holes central round diameter (mm):1800*Bolt quantity (kits):54*Bolt standard:M30*2Aerodynamic capabilities*Design tine speed rate:7.5*Maximum wind power utilization modulus (Cp):0.464*Air-movement form design :NACA63
