老产品高产牌AT60-6、40-6水轮泵,效率低,水头范围窄,结构不够合理。为了加速产品更新换代,湖南省农机所等单位研制成功了BS60—6、40—6高效率水轮泵,已鉴定。这种水轮泵也是机、泵同轴,但机、泵均选用高效模型,转轮抗汽蚀性能较好,使用水头范围2～7米,采用手动调速机构。和老产品比较,新产品的主要优点:1.效率高,总效率达68%,是我国目前效率最高的水轮泵,效率提高14%,节能显著;2.水头适应范围扩大了1.5倍,用
Old product high-yield brand AT60-6, 40-6 water pump, low efficiency, narrow head range, the structure is not reasonable enough. In order to speed up product replacement, Hunan Agricultural Machinery and other units developed a successful BS60-6, 40-6 high efficiency water pump, has been identified. This water pump is also a machine, pump coaxial, but machines, pumps are selected efficient model, anti-cavitation runner better performance, the use of head range of 2 to 7 meters, the use of manual speed control. Compared with the old products, the main advantages of the new products are as follows: 1. The high efficiency and the total efficiency of 68% are the most efficient water pump in our country, the efficiency is increased by 14%, and the energy saving is remarkable. 2. The adaptability of the water head is increased by 1.5 times, use
