Wybrane zagadnienia optymalizacji układów pompowych i ich regulacja zmiennoobrotowa

The paper presents problems connected with water systems in the industry and heating plants. Describes, that the most important are the lowering hydraulic loses and improving the technology of systems. The examples of the correct pumps curves and the possibilities of changing of them are presented. Also the energetistic consequences of the applying the variable-speed drives as a drives for centrifugal pumps are introduced. The article presents how the variable-speed drives cause the lowering efficiency of the pumps set and in the final effect the lowering total efficiency of the systems, specially when the surplus of the pumps head is to high. The all important parameters and conditions connected with correct project process are describes.
