Question:

Screw it diagonally, then pull it with pliers. It's impossible to replace the screw with an electric drill

Screw it diagonally, then pull it with pliers. It's impossible to replace the screw with an electric drill

Answer:

This can avoid the blades and the tower is not the bigger the better interference leaves the unit of weight is to rotate the blade on the centrifugal force control will be great strength to meet the whole leaf blade performance is mainly its aerodynamic shape in different wind speeds. The wind energy utilization coefficient is now the mainstream of domestic 1.5MW
The blade of wind power is very fine with this why so fine solid about in diameter of the impeller under a certain degree as small as possible with this cost related degree is in the vertical surface of the blade in the projection between the blade and the hub because of a cone angle transmission shaft and horizontal shaft or angle
Height at about 70 meters, that 1.5MW, a load running hours in 2000 hours or so, 1800 to 2500 hours range, 2000*1.5=3000MW rated wind speed, turn around, probably at about once electricity. Now Europe is developing 10MW, domestic companies are developing the largest, but 5MW
