负压风动送样装置鉴定会在长沙召开 由武汉钢铁设计研究院与长沙矿山通用机器厂共同协作研制的负压风动送样装置已于1984年7月份试制成功,经湖南大学测试结果,性能良好,9月份由一机部与冶金工业部在长沙联合召开部级鉴定会一致通过,并进行了现埸操作表演。该装置的各项技术指标已达到国外同类产品的先进水平,填补了冶金系统的一项空白。负压风动送样是国外70年代的一项先进技术,较正压送样装置的噪音小,系统干净,无油无水,样匣及试样不受污染,事故少,安全可靠,输送距离
Negative pressure pneumatic sampling device identification will be held in Changsha by the Wuhan Iron and Steel Institute of Design and Mining General Machinery Factory collaborative development of negative pressure pneumatic sampling device has been successfully trial production in July 1984 by the Hunan University test results, Performance is good, in September by a machine and the Ministry of Metallurgical Industry jointly held in Changsha, ministerial appraisal will be unanimously approved, and conducted a 埸 operation performance. The device of the technical indicators have reached the advanced level of similar foreign products to fill the metallurgical system of a blank. Negative pressure pneumatic feed sample is an advanced technology in the 1970s. Compared with the positive pressure feed sample device, it has the advantages of low noise, clean system, no oil and water, no sample box and sample contamination, less accidents, safe and reliable delivery distance
