ZYS Precision Bearing,Bearing Test Machine,Rolling mill bearing

Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

Usually people think that wind power is completely determined by the wind generator power

Usually people think that wind power is completely determined by the wind generator power, always wanted to buy a bigger wind turbines, which rotary table bearing is incorrect. The current wind generator just to the battery charge, while the energy stored up by the battery, it is the size of the end-use electrical power have a closer relationship with the battery size. But mainly depends on the magnitude of power of the size of the air volume, not just the size of the power head. In the Mainland, small wind turbines would be more appropriate than big. Because it is more likely to be driven by a small amount of wind power generation, continuous small wind, wind more than momentary supply large amounts of energy. When there is no wind it can also be caused by normal use of wind energy, which means that a 200W wind generator can also be used by a large battery and inverter fit, get 500W or 1000W and even more power out.
