去年10月,中国农机院、北京市水利局在北京顺义县牛栏山乡召开了推广牛栏山乡抓机井节能试点经验交流会。今年1月份又在该乡召开了机井节能示范点工作会议。继上次会议之后,井泵测改试点从1个扩大到6个,遍布4县6乡。6个示范点到去年底共测试井泵291台,有60～80%需要进行技术改造,现已改造井泵71台,改造后的井泵装置效率由原来的28%上升到39%,提高11%,如按年运行1000小时计,则平均每台井泵每年
In October last year, China Agricultural Machinery Institute and Beijing Municipal Bureau of Water Conservancy held a meeting to promote the pilot project of saving energy in experimental trials of Niulanshan Township in Niulan Township, Shunyi County, Beijing. In January this year, it held a working meeting on well energy saving demonstration sites in the township. Following the last meeting, the well pump test pilot was expanded from 1 to 6, covering 6 counties and 4 counties. A total of 291 well pumps were tested at the 6 demonstration sites by the end of last year, with 60-80% of them needing technological transformation. Now, 71 well pumps have been rebuilt. The efficiency of the reconstructed well pump devices has risen from 28% to 39% 11%, such as running 1000 hours a year, then the average of each well pump every year
