Calculation of energy costs of mobile technological transport units

Abstract

The article studies the issues of calculating and increasing the energy efficiency of high-pressure pumps used on mobile units of technological transport. As a promising direction for improving the energy efficiency of the specified mobile units, it is proposed to calculate the energy efficiency of high-pressure pumps of mobile units in order to establish analytical dependencies of energy consumption on changes in the operating temperature of the oil of pumps of units of technological transport. An analysis of modern publications and scientific research devoted to the topic of calculating high-pressure pumps of units of technological transport was carried out, and it was also established that the operation of high-pressure pumps is affected by many adverse factors that lead to an increase in energy consumption, therefore, the development of a mathematical apparatus for determining the energy consumption of mobile pumping units is an effective tool for energy saving. For this reason, the article creates a calculation model of energy consumption of high-pressure pumps of mobile units of technological transport and on its basis an assessment of energy losses of the high-pressure pump HT-400 of the Halliburton Tier IV DGB mobile unit is made. According to the obtained experimental studies, the maximum volumetric efficiency of a serviceable high-pressure pump HT-400 of Halliburton Tier IV DGB pumping units was achieved at a temperature of 53 °C and is equal to 0.89; the maximum volumetric efficiency of a serviceable high-pressure pump according to the calculation model was achieved at a temperature of 55 °C and is equal to 0.87. Based on the obtained experimental results, it is possible to confidently confirm the viability of the calculation model of the energy consumption of a high-pressure pump of mobile units of technological transport.
