Měření kavitace v hydraulickém obvodě

Abstract

This bachelor thesis is about cavitative phenomenon in hydraulic circumferences. In the introductory part of this work there is characterized cavitation in hydraulic circumferences. In the theoretical part of this bachelor thesis there are described individually the types of cavitation and the influence of dissolved and undissolved air in the fluid. In the practical part of the work there is realized a proposal of hydraulic circumference for practicator from Parker company which is used for investigation of cavitation on pump absorbing. The circumference was suggested and later assembled on a practicator from Parker company. On the assebled hydraulic circumference was done a practical measuring of cavitation on pump absorbing, where were measured pressures p on intake pipes and extrusion pipes and also the revolutions of (n) used to determine the volumentric rate of flow (Q) were recorded. Results are evaluated by the graph.
