本文介绍四冲程170F柴油机的单面及双面鼓风离心式风扇的特性。以及风扇流量脉动的试验和分析,对比了使用两种风扇的柴油机全负荷特性,试验结果表明,采用双面鼓风离心式风扇可提高该机的性能。
This article describes the characteristics of single-sided and double-sided blower centrifugal fans for four-stroke 170F diesel engines. As well as the fan flow pulsation test and analysis, compares the full load characteristics of diesel engines using two kinds of fans, the test results show that the use of double-sided blast centrifugal fan can improve the performance of the aircraft.
