摘要
栓流式气力输送系统在渔业工厂化养殖中的应用,极大地提高了工厂化养殖的自动化程度。气力输送系统的设计一般包含发送罐、输送管道和集装容器三部分内容,而系统的能耗和输送能力主要取决于输送管道设计的合理性,但传统的设计方法依赖于经验公式,缺乏理论支撑,缺少适用于输送管道的一般性设计公式,往往导致气力输送系统的能耗大、输送能力低下等问题。针对上述问题,建立了设计因素和动力指数的关系式,方差分析结果表明回归方程具有较高的可靠性,通过优化设计,降低了动力指数,达到了精确设计的目的。
Plug flow pneumatic conveying system has been widely used in the fishery factory farming, improving the degree of automation of the fishery factory farming. The design of pneumatic conveying system generally consists of sending tanks, pipelines and containers of three parts, which mainly depends on the energy consumption of the system and the transmission capacity in pipeline design is reasonable But the traditional design method based on experience formula is lack of theoretical support and general design formula, which often leads to problems of energy consumption and low transmission capacity. For the problem discussed above, the relation between the design factors and dynamic index has been built, variance analysis results show that the regression equation with high reliability and optimal de- sign, can improve the transmission capacity of transportation system, reduce energy consumption, and achieve the purpose of accurate design.
