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2～50m^3／h，扬程400—1600m范围内，流量越小、扬程越高，皮托管泵的技术优势就越明显。
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 m^3/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.
