【摘要】 介绍了皮托管泵的起源、发展简况、结构、工作原理、性能参数及特点。用工程实例,给出了皮托管泵与高速泵和多级泵的技术经济评价表。工程实践表明,在流量2~50 m3/h,扬程400~1 600 m范围内,流量越小、扬程越高,皮托管泵的技术优势就越明显。更多还原

【Abstract】 In this article,the origination,development process,structure,working mechanism and characteristics of pitot pump were introduced.With engineering instance,the engineering-economy evaluation table for pitot pump,high velocity pump and multi-stage pump was presented.It has been shown that within the scope of 2 ~ 50 m3/h in flow and 400~1 600 m in pressure head,the lower flow and the higher head,the more evident the technical advantage of pitot pump has.更多还原
