Abstract

This bachelor thesis is focused on the problematics of verifying the operating point of hydrodynamic pump in accordance with the relevant standard "Hydrodynamic pumps - Acceptance tests of performance parameters - Accuracy grades 1, 2, and 3 under the designation ČSN EN ISO 9906. The theoretical part describes machines for transporting liquid substances, their classification, and explains the individual principles and characteristics of pumps. Additionally, energy balances of the pumping system are presented. The practical part describes the measurement of the operating point on a specific device and the processing of these measurements. In conclusion, an evaluation is made as to whether the given hydrodynamic pump fulfils guaranteed parameters.
