1983年12月26日至28日,中国有色金属工业总公司科技部在北京主持召开Ky-11型定量隔膜泵鉴定会。出席鉴定会的有地质、选矿、冶金、化工、煤炭、大学等14个单位23名代表。 Ky-11型定量隔膜泵是北京矿冶研究总院于1981年9月开始研制的,1982年8月试制出第一批样机,并完成泵的清水性能测定和输送矿浆的试验。为了检测泵在特殊情况的适应能力,进行了200小时的连续运转试验以及大颗粒堵塞、突然停车、启动等性能试验。在此基础上改进设计,于1983年6月
From December 26 to December 28, 1983, the Ministry of Science and Technology of China Nonferrous Metals Industry Corporation presided over the Ky-11 quantitative diaphragm pump appraisal meeting in Beijing. There were 23 representatives from 14 units attending the appraisal meeting, including geology, mineral processing, metallurgy, chemical industry, coal and university. Ky-11-based quantitative diaphragm pump is Beijing Research Institute of Mining and Metallurgy began in September 1981 developed in August 1982 trial production of the first batch of prototype, and to complete the determination of water pump performance and transport of pulp test. In order to test the ability of the pump to adapt to special situations, a 200-hour continuous run test, performance test of blockage of large particles, sudden stop and start-up were carried out. On this basis, to improve the design, in June 1983
