В статье выполнен сравнительный анализ производительности КН, изготовленных тремя компаниями. Исходными данными послужили находящиеся в открытом доступе результаты испытаний КН этих трех компаний. Для моделирования подачи коловратными насосами плавленых сыров (ПС), сгущенного молока и др. следует использовать подход, базирующийся на нагрузочных характеристиках при перекачивании сред с наибольшими значениями эффективной динамической вязкости (ЭДВ). Производительность КН рассчитывается как произведение рабочего объема на разность между текущей частотой вращения ротора (ЧВР) и ее минимально необходимым значением (МНЗ) для начала подачи жидкости. МНЗ ЧВР у всех изученных КН снижается с увеличением ЭДВ и уменьшением перепада давления. Но абсолютные МНЗ ЧВР могут существенно различаться у разных КН при ЭДВ менее 200 сПз. Для корректного сравнения производительности КН с небольшим различием рабочего объема предложен метод приведения нагрузочной характеристики к безразмерной форме (зависимость безразмерной подачи от безразмерных величин перепада давления и ЧВР). Из трех исследованных агрегатов безразмерная подача КН 034-WCB оказалась наибольшей, однако разница между величинами безразмерной подачи разных КН была существенной лишь при перепаде давления около 1 МПа и ЭДВ менее 300 сПз. ПС, как правило, транспортируются при меньших давлениях. В таких условиях разница безразмерной производительности исследованных КН становится малозначимой. Результаты данного исследования могут быть использованы для подбора КН с необходимыми параметрами.</p></abstract><trans-abstract xml:lang="en"><p>Lobe pumps (LP) are used for transporting food media with high viscosity when it is necessary to preserve a product structure. The article presents a comparative analysis of the LP performance manufactured by three companies. The publicly available test results of these three companies are served as the initial data. The approach based on the load characteristics when pumping media with the highest values of effective dynamic viscosity (EDV) has been used to simulate the performance of processed cheese (PC) by the lobe pumps. LP performance is calculated as the product of the working volume by the difference between the current rotor speed (RS) and its minimum required value (MRV) to start the liquid flow. The MRV RS decreases with an increase in EDV and a decrease in pressure drop in all studied LP. However, the absolute MRV RS may differ significantly for different LP with an EDV of less than 200 sP. The method is proposed for reducing the load characteristic to a dimensionless form (the dependence of the dimensionless performance on the dimensionless values of the pressure drop, EDV and the RS for a correct comparison of the LP performance with a small difference in the working volume. The dimensionless feed of LP 034-WCB turned out to be the largest of the three studied aggregates. However, the difference between the values of the dimensionless performance of different LP turned out to be significant only at a pressure drop of about 1 MPa and an EDV of less than 300 sP. PS, as a rule, are transported at lower pressures. Under such conditions, the difference in the dimensionless performance of the studied LP becomes insignificant. The results of this study can be used to select LP with the necessary parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коловратные насосы</kwd><kwd>производительность</kwd><kwd>вязкость</kwd><kwd>давление</kwd><kwd>безразмерная форма</kwd><kwd>моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lobe pumps</kwd><kwd>performance</kwd><kwd>viscosity</kwd><kwd>dimensionless shape</kwd><kwd>modeling</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания НИОКР «Разработка и совершенствование продукционных систем пищевой отрасли».</funding-statement><funding-statement xml:lang="en">The research was carried out within the framework of the state assignment of research and development work "Development and improvement of food industry production systems".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Горбатов, А.
