中文摘要:针对箱涵式进水流道底部易产生涡带的问题,根据涡管强度守恒定理提出了4种新型的消涡装置,为验证4种消涡装置的有效性,采用高速摄影技术分别对设置4种消涡装置的泵装置吸水喇叭管进口处的流态进行了摄影,成功捕捉到不同工况时涡带的生成,分析了有无消涡装置及2种新型消涡装置对泵装置能量性能的影响,分析表明,采用新型消涡装置不仅能消除箱涵式进水流道底部的涡带,还可改善喇叭管内部流态,提高泵装置的能量性能。

Abstract:In order to solve the problem of bottom-vortex in the cube type suction passage of pump 4 types of vortex-elimination devices were designed based on the vortex tubes intensity conservation theorem. To verify the validity of these devices, the test-rig was set up for experiment and the high-speed photography was applied to the flow pattern of the suction passage with different types of vortex-elimination devices. The bottom vortices in the original passage were captured successfully under different operation conditions. The effects of 4 new vortex-elimination devices on the hydraulic performance of pump system were analyzed based on the energy test. The results show that the new vortex-elimination device can eliminate the bottom vortex, the flow pattern of flare and the hydraulic performance of pump system can be improved.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
