历时六个月的全国轻、小型喷灌机具评比已经揭晓,参加评比的喷灌机组共65台(套),被评为一等品的17台(套)、合格品的17台(套),合格品以上的机组占总数的52.3%。这次评比是很严格的,是按照农机部颁布的产品质量检验试行标准并参照部颁水泵、喷头标准进行的,评比分数基本上来源于各项测试结果。为了科学评价喷灌机组的优劣,共进行了七个项目的测试工作,即:机组运行工况点的测定;150小时可靠性试验;水泵性能(包括汽蚀、自吸)试验;喷头性能试验;管道试验;内燃机负荷特性试验和主要零件加工质量的检测。共测试了六万二千多个原始数据,通过17万多次运算最后得出测试结果。根据
The evaluation of the national light and small sprinklers which lasted for six months has been announced. A total of 65 sprinkler units (sets) were selected for the competition, and 17 units (sets) of first-class products and 17 units (sets) of qualified products were qualified The above units accounted for 52.3% of the total. The rating is very strict, according to the Ministry of Agricultural Machinery promulgated the product quality inspection pilot standards and reference ministerial pump, nozzle standards, the scores are basically derived from the test results. In order to scientifically evaluate the advantages and disadvantages of sprinkler units, a total of seven projects were tested, namely: the determination of operating conditions point; 150 hours reliability test; pump performance (including cavitation, self-priming) test; nozzle performance test ; Pipeline test; internal combustion engine load characteristics test and main parts processing quality inspection. A total of more than 62,000 raw data were tested, and the test results were obtained through more than 170,000 operations. according to
