IMPROVEMENT OF THE PRESSURE REGULATION SYSTEM IN THE MAIN PIPELINE

Abstract

One of the features of the operation of pumping stations for water intake and pumping is the fundamentally uncertain mode of their operation, which often does not allow a clear decision on the choice of working machine at the design stage. The main requirements for the water supply system are to ensure a given pressure for water consumers at constant and variable water flows. This task is complicated by the fact that during the operation of the pumping station, the operating modes of the installation change significantly. Therefore, the main problem of water transportation is to maintain a given pressure. The analysis of methods for regulating the supply of pumping stations has shown that almost all of them are aimed at technological tasks and practically do not take into account the energy aspects of water transportation, which leads to losses of consumed electricity due to inefficient operation of the throttle body, the creation of excess pressure in the pipeline and various kinds of water leaks in the network and at the consumer. In addition, the issue of smooth pressure regulation in the pipeline is also relevant due to the fact that sudden changes in pressure in the pipeline are the largest and most common cause of failure of pumping station equipment. Therefore, the purpose of the work is to reduce the energy costs of the pumping station through the development and research of an automated pressure control system in the main pipeline. Modern approaches to solving this problem are associated with the use of frequency converters in the pump control circuit, which allows water transport with smooth and accurate regulation of the operating parameters of the pumping unit without unproductive electricity consumption. Improving the pressure control system in the main pipeline allows you to improve the operation of the system, which increases the technical and economic performance of the pumping station and reduces the losses of the enterprise.
