Original abstract

Pumping station supplies water for technological process. The check valve in the station was replaced with a new one. The regular test of black out discovered the high pressure pulsations accompanied with noticeable pipeline movement of discharge pipe. It was caused by late check valve closing, probably, when the back flow reached the highest possible velocity. This statement was supported with analysis of results of pressure measurement near the check valve and with a numerical simulation of the flow in the pipeline system.

Czech abstract

Čerpací stanice dodává vodu pro technologický proces. Zpětný ventil na stanici byl nahrazen novým. Pravidelná zkouška výpadku objevila pulsace vysokého tlaku spolu s znatelným pohybem výtlačného potrubí. To bylo způsobeno pozdním zavřením zpětné klapky, pravděpodobně, když zpětný tok dosáhl nejvyšší možné rychlosti. Toto tvrzení bylo podpořeno analýzou výsledků měření tlaku poblíž zpětného ventilu a numerická simulace proudění v potrubním systému.
