The world's first hydraulic wheel
Water transfer wheel, Song Yuan Dynasty in 1313 with the invention, a book by Wang Zhen "agricultural book" in fig.. It is a kind of bast fiber bonding wiremachine, by human wheel was converted into. Main is divided into two parts the spinning wheel and the transmission. Spinning long two Zhang Yu, width of five feet. A transmission part at the wheel on both sides, each with a wheel, a wheel of which the external end of a turbine, turbine and loom with leather strings will beconnected, so that the wheel moving motor. Then use the flowing water turbinework, the spinning wheel to rotate, instead of manpower, improve work efficiency.The spinning wheel was already about 700 years, the hydraulic spinning abroad than the earliest (hydraulic spinning British Richard Acle invented in 1769) as early as 400 years, is the world's earliest hydraulic wheel.
