往复泵不同吸入系统配置的实验研究

往复泵吸入性能好坏与吸入来统配置有关。为了研究吸入系统配置对往复泵吸入性能的影响，实测了不同吸入系统配置时往复泵的工作特性。分析了吸入性能与吸入系统配置之间的关系。确定了最佳吸入系统配置方案。通过对实测结果分折，得出泵阀滞后现象不仅与吸入性能有关，还与泵的轴向间隙和排出压力有关，且总是存在的结论。

Experimental Study of Different Suction System configuration of Reciprocating Pump

As is known，the hydraulic performance of a reciprocating pump is affected by its suction system configuration. in order to study how the suction system configuration affects the pump's hydraulic performance，this paper analyzes the working performances of the reciprocating pump with changeable suction system configuration，and the relation between suction performance and suction system configuration，thus determining the best suction system configuration. The experimental results show that the pump's hydraulic performances have much to do with other important phenomena，which were observed and analyzied during the experiment.
