In conditions of constant growth of deficit and prices for energy resources (water, energy), more and more attention of consumers is paid to energy efficiency (efficiency) of pumping equipment. Many years of practice show that when designing even simple pumping units for any purpose, there are difficulties in choosing the necessary pumping equipment with energy-efficient modes. An important point in the study of energy-efficient modes of operation and construction of energy characteristics of household centrifugal pumps such as BCN is to conduct experimental studies.
The aim of this work is to create an experimental stand with closed fluid circulation, throttle control of pump performance with the possibility of their parallel and series connection to determine energy-efficient modes of power consumption.
The theoretical and experimental component of determining the energy efficiency modes of power consumption was carried out through the development and creation of an experimental stand for the study of operating modes and construction of energy characteristics of household centrifugal pumps type BCN.
Control and measuring devices and methods of parametric tests of centrifugal pumps to determine the loss of power consumption in each mode, provided the necessary accuracy of the physical experiment.
Key words: centrifugal pumps, power consumption, throttle control, pump characteristics, resource savin.
