EXPERIMENTAL STUDIES ON DETERMINATION ENERGY EFFICIENCY OF PUMPING UNITS IN AIC ENTERPRISES
The increase in the energy intensity of agricultural production and the constant rise in energy prices are one of the main factors that increase the importance of the issue of energy efficiency and energy conservation in consumer energy systems. Energy efficiency management in consumer energy systems is based on the finite relationship method. The essence of the method lies in the fact that the efficiency of any energy process is assessed by an objective indicator - relative energy intensity. Relative energy capacity is the ratio of energy parameters (energy or power) at the input and output of the structural element under consideration, including superunits in its numerical value, the energy losses in the element, referred to the transmitted energy (power). The dependences of the output power of asynchronous electric motors on the ambient temperature and height above sea level are given. An example of the sequence of calculating the energy consumption of pumping units and the results of experimental studies of pumping units are given.
