Technological regulations of the multistage pump impellers

Abstract

Almost half of all energy produced in the country feeds the rotary machines - pumps and compressors. Their usage in all industries is a wide range, depending on their function. Moreover, the current challenges require the energy efficiency of such units’ designs, increasing the requirements for vibration performance, reliability and impermeability. Nowadays the types of manufacturing systems, based on knowledgebased technologies, output the information to the level of the most important resource. They make it a growing factor of production efficiency. Information resource status has become an integral part of the production process alone with material factors of production.
