有人把太阳能水泵比作是农家的“及时雨”,这并不夸张。因为每当酷暑热浪席卷大地之时,正是它大显身手之际。它能为濒于干枯的禾苗,及时送来甘露。利用太阳能提水灌溉,多年来一直是人们在努力研究的课题。但是,目前研制的太阳能水泵结构比较复杂,价格也较贵,影响了它的推广使用。北京市太阳能研究所研制的BT-SⅡ型太阳能水泵是一种新型水泵,它结构简单,造价较低,适合在无电源的边远地区使
It is no exaggeration to suggest that solar-powered pumps are compared to “timely rain” in the farmhouse. Because whenever the heat of summer heat swept through the earth, it is the occasion of its full display. It can be on the verge of dry grasses, timely delivery of nectar. The use of solar water for irrigation has been the subject of hard work for many years. However, the current development of solar pump structure is more complex, the price is more expensive, affecting its promotion and use. Beijing Solar Energy Research Institute developed BT-S Ⅱ solar pump is a new type of pump, its simple structure, lower cost, suitable for use in remote areas without power supply
