Description

(54) ОДНОВИНТОВОЙ НАСОС(54) SINGLE-PRINT PUMP

Изобретение относитс  к области гидромашиностроени ,-в частности к средствам дл  транспортировани  жидкости и пластичных подвижных составов , и-может найти применение в ... строительстве и других отрасл х наро ного хоз йства. Известна конструкци  одновинтового насоса с гуммированным статорой, охватываемым упругим хомутом, снабженным горизонтсшьньлми планками со ст гивающими крепежными элементами 1. Этот насос содержит камеру, заполненную вспомогательной средой, взаимодействующей с рабочей средой через разделитель сред и имеющей дав ление, завис щее от Дс1злени  в напор ной, магистрали. Под действием этого давлени  упругий хомут деформируетс  и обжимает статор с силой, завис щей от давлени  в напорной магистрали на соса.. : Недостатком известной конструкции  вл етс  ее сложность и невысока , на дежность , обусловленна  образованием пробок рабочей жидкости ,в лабиринтах и тупиках камеры, а также утечки вспо могательной среды. Целью изобретени   вл етс  повышение надежности насоса путем упрощени  его конструкции. Цель достигаетс  тем/ что вдоль упругого хомута вплотную к одной из его горизонтальных планок дополнительно установлены эластичный напорный рукав и накладка, взаимодействующие посредством крепежных ст гивающих элементов с упом нутыми планками. На фиг. 1 изображен предлагаемый насос, продольный разрез; на фиг. 2 - разрез А-А на фиг. (при минимальном давлении в эластичном напорном рукаве); на фиг. 3 - то-.же (при максимальном давлении в эластичном напорном рукаве). Описываемый одновинтовый насос содержит однозаходный ротор 1, установленный в двухзаходный гуммированный статор 2, охватываемый упругим хомутом 3. Хомут 3 имеет паз, выполненный параллельно оси статора, и снабжен нижней 4 и верхней 5 горизонтальными планками. К одной из горизонтальных планок, например к верхней 5, вдоль упругого хомута дополнительно установлены накладка 6 коробчатого профил  и эластичный напорный рукав 7, установленный параллельноThe invention relates to the field of hydraulic engineering, in particular, to means for transporting liquid and plastic rolling stock, and can be used in construction and other sectors of the national economy. The known design of a single-screw pump with a gummed stator, covered by an elastic collar, equipped with horizontal bars with tightening fasteners 1. This pump contains a chamber filled with auxiliary medium interacting with the working medium through a media separator and having a pressure depending on the flow pressure factor. highways. Under the action of this pressure, the elastic collar is deformed and compresses the stator with a force depending on the pressure in the pressure line on the pump ..: A disadvantage of the known construction is its complexity and low reliability due to the formation of traffic jams in labyrinths and dead ends of the chamber, as well as auxiliary leaks. The aim of the invention is to improve the reliability of the pump by simplifying its design. The goal is achieved by the fact that along the elastic collar, close to one of its horizontal bars, there is additionally installed an elastic pressure sleeve and an overlay, interacting by means of fastening tension elements with the said bars. FIG. 1 shows the proposed pump, a longitudinal section; in fig. 2 shows section A-A in FIG. (with minimal pressure in an elastic pressure hose); in fig. 3 - the same. (With the maximum pressure in the elastic pressure hose). The described single-screw pump contains a single-rotor 1 mounted in a double-pole gum stator 2, covered by an elastic collar 3. The collar 3 has a groove made parallel to the stator axis and provided with a lower 4 and an upper 5 horizontal bars. To one of the horizontal strips, for example, to the top 5, along with an elastic collar, an overlay 6 of a box-shaped profile and an elastic pressure sleeve 7 installed parallel to
