增氧机具随着水产养殖业的发展得到了迅猛发展,主要型式有叶轮式、水车式、喷水式、涌浪式、射流式和螺旋桨吸气搅拌式等。据调查,目前全国生产增氧机的企业约五十家,年产量大多为几千台(套),年产量在万台以上的有三四家。这些企业近年的年产销量共为12万台左右。总产量中叶轮式约占65％,水车式约占20％,其他类型的约占15％。为了给水产养殖业选用经济、高效的增氧机具提供依据,我们对市场占有率最高的叶轮式增氧机与新研制的螺旋桨吸气增氧机的生产性能进行了测试与比较,现报告如下。
Aerobic equipment with the development of aquaculture has been the rapid development of the main types of impeller, waterwheel, water jet, surge, jet and propeller suction stirring and so on. According to the survey, at present, there are about 50 enterprises that produce aerator in the country, most of which have annual output of several thousands (sets) and 34 or more annual output of more than 10,000 sets. In recent years, these enterprises have an annual output of about 120,000 units. Among the total output, about 65% are impeller types, about 20% for water tankers, and about 15% for other types. In order to provide a basis for the selection of an economical and efficient aerator for the aquaculture industry, we tested and compared the performance of the newly developed propeller aeration aerator with the highest market share of the impeller aerator. The report is as follows .
