Comparison of Equipment Used for Regulation of Working Characteristics of the Main Pumps on Oil Pipelines

Abstract

The main goal of this article is to determine the most effective and reliable method for changing the characteristics of pumping units. Since during the operation of pumping units the consumption of hydrocarbon energy carriers by consumers is unstable, the question arises of reducing the energy costs for the the electric motors input at pumping units. There are a number of methods for solving this problem. Here we will consider two basic and effective methods of regulating the performance that are currently used at the constructed pumping stations: the use of a frequency-controlled drive and a hydraulic coupling. A number of advantages and disadvantages of these methods are given and a conclusion is made as to which is more suitable both in terms of efficiency and reliability.
