Abstract Concerning to the present problems,the structure of a new type of non-leakage vertical self-priming pump is improved by fitting impeller and vane together,setting ribbed slab in moisture separation chamber to shorten the self-priming time,taking special structure at inlet to prevent siphonage without using check-valve or vacuum breaking valve,and adopting rotating dynamic seal and framework oil seal to avoid the problems such as leakage of packing seal and maintenance for mechanical seal.According to the comparison of the pre and post structures′ test results,it is concluded that the gap between vane and impeller and the structure of rotating dynamic seal have great effect on self-priming performance,and it is necessary to balance the axial force.Improved approach and analysis calculation which are useful for reasonable design are recommended in detail associated with experimental data.
