Abstract

According to the conducted studies, the greatest impact on the electric drives of production machines and mechanisms is exerted by deviations and asymmetry of the surface.

Voltage asymmetry leads to losses that have an electromagnetic and technological component.

Studies on the effect of voltage asymmetry on the technological characteristics of working machines and mechanisms have shown that their productivity decreases with voltage asymmetry. However, there are no studies on the influence of spring asymmetry on the energy characteristics of working machines.

The purpose of the research is to determine the effect of voltage asymmetry on the energy characteristics of pumping units.

With voltage asymmetry, constant and variable losses in an asynchronous electric motor change.

It is proposed to carry out an energy assessment of the pumping installation based on the specific consumption of electricity.

A study of the effect of voltage asymmetry on the energy characteristics of pumping units was carried out. The dependence of the specific power consumption on the change in stiffness of the mechanical characteristics of the electric motor, which is caused by voltage asymmetry, is obtained. It was established that slippage and power losses increase with voltage asymmetry. As a result, the specific losses of electricity in pumping units are increasing.

Key words: pump installation, voltage asymmetry, power, pump performance, specific power consumption
