在国民经济各部门中,农业排灌用泵数量占泵类拥有量总动力的65%。全国现有52万座排灌站,230万眼机电井,农用泵保有量700多万台,配套动力7800万马力,占农机总动力的40%,耗电量约为全国总用电量的5～10%。全国近千家农用泵制造厂,产品质量相差悬殊,同一图纸不同厂家生产的水泵效率相差最高可达25%。好的产品用户欢迎,进入国际市场;质量低劣粗制滥造的产品必须淘汰。总的看,目前使用的农用泵大多数效率偏低,能源浪费大,与国外同类产品相比,与国内正在发展的新型产品相比,使用效率平均低10%,寿命约低50%。
In all sectors of the national economy, the number of pumps for agricultural drainage and irrigation accounts for 65% of the total power of pumps. There are 520,000 irrigation and drainage stations in the country, 2.3 million electro-mechanical wells, 7 million agricultural pumps and 78 million horsepower, accounting for 40% of the total power of agricultural machinery. The power consumption is about 5% of the national total electricity consumption ~ 10%. Nearly a thousand agricultural pump factories across the country, product quality difference between the same drawing different manufacturers of pumps up to 25% efficiency difference. Good product users are welcome to enter the international market; poor quality shoddy products must be eliminated. In general, most of the currently used agricultural pumps are inefficient and energy wasted. Compared with similar foreign products, the average efficiency of use of agricultural pumps is 10% lower and their life expectancy is about 50% lower than that of new products under development in China.
