In the Kaliningrad region there are about 70 % of all polder lands in Russia. On these lands with high potential fertility, it is advisable to intensive agriculture. The area for the average moisture year is an area with excessive moisture, which indicates the need to maintain the rate of drainage on agricultural land. Many different factors play a role in ensuring the drainage rate, one of which is pumping stations and pumping equipment installed on them. An important parameter in the use of pump-power equipment is energy consumption, since in this industry it is a considerable expense item. Improving the energy efficiency of pumping stations on polders is a pressing issue today. At the majority of polder pumping stations, domestic power pumping equipment is installed with excess power and head of 4–8 meters, and a new one is selected based on the maximum possible head in a given place. In the Kaliningrad region, the energy efficiency of polder pumping equipment has never been analyzed. In this paper, a statistical processing of the geodesic pressure of water at the polder pumping stations of the Slavsk region for 2000–2002 was carried out. On the basis of these data and data on the hydraulic characteristics of pressure pipelines, the calculated water pressures were determined for the rational selection of pumping equipment. The calculation of the economic efficiency of pumps with optimal power compared with pumps of excess capacity. The results of the study can serve as a justification for the transition to the pumping equipment with less power and pressure, which will lead to a decrease in the cost of money for electricity.

Preparatory Work

The challenges of increasing the energy efficiency of the economy as a whole and of certain production sectors in particular are a priority both in our country and abroad. As part of the energy policy of the Russian Federation to reduce the specific energy intensity of enterprises in the oil transportation system, Transneft PJSC developed and implements the energy saving and energy efficiency improvement Program. The application of energy-saving technologies allowed the company to significantly reduce operating costs and emissions of harmful substances. At the same time, further reduction of energy costs is complicated for objective reasons. The objective of this article is to present additional methods to improve the energy efficiency of oil transportation by the example of the organizational structure of Transneft. Possibilities to reduce energy costs in the organization of the operating services, planning and execution of work to eliminate defects and preparatory work for the scheduled shutdown of the pipeline, the use of pumping equipment, including pumps with variable speed drive, the use of various pipelines layouts, changing the volume of oil entering the pipeline system and increase its viscosity.

Приведен опыт применения частотно-регулируемых электроприводов на насосных станциях ООО Водоканал г. Новокузнецка. Приводятся преимущества и недостатки данного технического устройства. Показано, что в настоящее время использование частотно-регулируемых приводов позволило снизить потребление электроэнергии более чем на 20, уменьшить затраты на ремонт и обслуживание, повысить срок службы электродвигателей, уменьшить величину пускового тока, снизить утечки воды и нагрузку на насосное оборудование и трубопроводную арматуру. Применение частотно-регулируемых электроприводов оправдало себя и в тех случаях, когда требуется регулирование параметров для обеспечения технологии (регулирование скорости, производительности и т. д.), приведение параметров оборудования к требуемым значениям без его замены (в расчете на увеличение загрузки оборудования до номинала в последующий период), компенсация суточной неравномерности потребления воды.The experience of using variable speed drives at the pumping stations operated by Vodokanal LLC in Novokuznetsk is presented. The advantages and disadvantages of this technical device are specified. It is demonstrated that currently, the use of variable speed drives provides for reducing the energy consumption by more than 20, reducing the repair and maintenance costs for improving the service life of electric motors for reducing inrush current, water leaks and the load on the pumping equipment and pipeline valving. The use of variable speed drives has paid off even in case where adjusting the parameters to ensure the technology (velocity, performance, etc.) bringing the equipment parameters to the required values without replacing it (in order to increase the equipment load to the nominal value for the subsequent period) compensating for daily irregularities in water consumption are required.

Pumping Equipment

The pumping of sewage sludge solids is reviewed in terms of handling high and low viscosity materials with solids concentrations varying from about 4 % to perhaps 50 %. Knowledge of rheological characteristics including thixotropy is necessary in designing pumping systems with sludge solids percentages, volatile content, particle size, abrasives content and temperatures being variables which could change pump types found suitable from facility to facility. The characteristics of a sewage collection system is also important in determining pumping parameters needed in a treatment plant. Solids handling equipment from other industries have made significant contributions to sewage solids pumping in recent years. Included are moyno-type progressing cavity screw-centrifugal, recessed impeller rotation piston positive displacement, and two cylinder piston S-transfer positive displacement pumps. Pumping equipment used in the F.R.G. and in Southern California in the U.S.A. is remarkably similar. These types of pumps offer the possibility of designing optimum solids dewatering and transfer systems.
