      <abstract xml:lang="ru">
        <p>Северная часть территории Республики Саха (Якутия) богата многочисленными россыпными месторождениями алмазов. Данные месторождения разрабатываются горно-добывающей компанией «Алмазы Анабара», которая занимается извлечением алмазов на сезонных обогатительных фабриках при помощи различного технологического оборудования. Одним из ключевых видов оборудования является пульповый насос зарубежной фирмы «KETO». Работа пульповых насосов данной фирмы при обогащении алмазосодержащего сырья сопровождается интенсивным гидроабразивным изнашиванием их рабочих колес, срок службы которых обычно не превышает трех месяцев. Практика показывает, что несвоевременная замена изношенного рабочего колеса может привести к аварийным поломкам уплотнительных элементов и подшипников, что объясняется сверхдопустимыми прогибами вала насосного оборудования, возникающими из-за значительной разбалансировки ротора. Главной причиной поломок пульповых насосов на сезонных обогатительных фабриках компании «Алмазы Анабара» является невозможность оперативно идентифицировать их предельное техническое состояние, ключевым признаком наступления которого является предельный износ рабочего колеса. Сезонные обогатительные фабрики компании «Алмазы Анабара» в настоящее время нуждаются в простом и в то же время достоверном диагностическом признаке достижения пульповыми насосами предельного технического состояния, идентификацию которого можно оперативно выполнить без их разборки и использования сложной аппаратуры, что очень важно при эксплуатации насосного оборудования в период короткого промывочного сезона на Крайнем Севере.</p>

      <abstract xml:lang="en">
        <p>The northern part of the territory of the Republic of Sakha (Yakutia) is rich in vast deposits of diamonds. These deposits are developed by the mining company “Almazy Anabara”, which is engaged in the extraction of diamonds at seasonal processing plants using various technological equipment. One of the key types of equipment is the pulp pump of a foreign company “KETO”. The work of pulp pumps of this company in the enrichment of diamond-containing raw materials is accompanied by intensive hydroabrasive wear of their impellers, the service life of which usually does not exceed three months. In practice, untimely replacement of a worn impeller can lead to emergency breakdowns of sealing elements and bearings, which is explained by super-permissible deflections of the shaft of pumping equipment arising from a significant unbalance of the rotor. The main cause of breakdown of slurry pumps at “Almazy Anabara” seasonal processing plants is the inability to quickly identify their ultimate technical condition, the key sign of which is the maximum wear of the impeller. The seasonal beneficiation plants of “Almazy Anabara” currently need a simple and at the same time reliable diagnostic sign of pulp pumps reaching their ultimate technical state, the identification of which can be quickly performed without disassembling and using complex equipment, which is very important when operating pumping equipment in short wash season on the Far North.</p>
