一种由畜力、风力机驱动的多缸水泵近日在河北阜城县农业机械化研究所研制成功,并向国家专利局申请了专利。该泵改变多年贯用的曲柄连杆传动机构,采用了摆环传动、行星轮差速。提水工作部件采用缸筒活塞或折叠胶质泵筒。且有结构紧凑、设计新颖、功耗少、流量系数大 A kind of multi-cylinder pump driven by animal power and wind turbine has been successfully developed at the Institute of Agricultural Mechanization in Fucheng County, Hebei Province and applied for a patent to the State Patent Office. The pump used for many years to change the crank connecting rod transmission mechanism, using a pendulum ring drive, planetary differential wheel. Water lifting work parts cylinder piston or folding gel pump cylinder. And a compact, innovative design, low power consumption, flow coefficient
