摘要

本文指出了液压系统中瞬态的频繁发生。特别注意的是水锤现象-这一现象的原因和影响。对这一现象还没有一个完整的分析描述。新的理论模型仍在发展中，需要实验验证。本文重点介绍了液压管道水锤实验台架的研制情况。提出了对实验台的后续修改，以达到关闭阀的速度及其密封性，以及尽量减少脉动对所研究的管道供应泵的性能的影响。最后展示的展台还允许测试各种类型工作流体(油，乳化液，蒸馏水)的液压管路中的瞬态。

UNSTEADY FLUID FLOW IN PRESSURISED CLOSED PIPES IN EXPERIMENTAL BENCH EXAMPLES

The paper indicates the frequent occurrence of transient states in hydraulic systems. Particular attention was paid to the phenomenon of water hammer – the causes and effects of this phenomenon. A complete analytical description of this phenomenon has not yet been developed. New theoretical models are still being developed and need to be verified experimentally. The paper focuses on presenting the development of experimental stands for the study of water hammer in hydraulic pipes. Subsequent modifications of the experimental stands for the speed of the shut-off valves and their tightness, as well as for the minimisation of the occurrence of the effects of the pulsation of the performance of the pump supplying the line under investigation, are presented. The stand presented as the final one also allows the testing of transients in hydraulic lines for various types of working fluid (oil, emulsion, distilled water).
