Цель изобретени - повышение долговечности путем уменьшени износа рабочих органов.The purpose of the invention is to increase durability by reducing the wear of the working bodies.
На фиг. 1 схематично представлен винтовой насос, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 schematically shows a screw pump, a longitudinal section; in fig. 2 is a section A-A in FIG. one.
Винтовой насос содержит полый корпус 1, установленную в его расточке 2 упругую обойму 3, выполненную в виде пакета 4 15 coca, перемещающа с в поперечном на- подвижных относительно друг друга и за- правлении в корпусе 1, не испытывает иса образуемые между овальной расточкой 2 корпуса 1 и охватывающей обойму 3 герметичной эластичной оболочкой 8 замкнутые полости 17, перемеща сь вместе с жидкостью от всасывающих отверстий 15 к напорному отверстию 16, создают тем самым движение потока перекачиваемой жидкости с определенными напором и производительностью . При этом герметична эластична оболочка 8 как рабочий орган нафиксированных от проворота пластин 5, и винт 6. Расточка 2 корпуса 1 выполнена овальной формы, а пакет 4 пластин 5 выполнен с общей расточкой 7 овальной формы , в которой установлен винт 6 и снабжен охватывающей его герметичной эластичной оболочкой 8, креп щейс к корпусу 1. Большие оси 9 и 10 соответственно овальных расточек пакета 4 пластин 5 и корпуса 1 расположены взаимно перпен- 25 дикул рно.The screw pump contains a hollow body 1, which is installed in its bore 2, elastic casing 3, made in the form of a package 4 15 coca, moving in transversely movable relative to each other and fitting in case 1, does not experience isa formed between the oval bore 2 housing 1 and enclosing the holder 3 sealed elastic sheath 8 closed cavities 17, moving together with the liquid from the suction inlets 15 to the pressure opening 16, thereby creating a flow of the pumped liquid with a certain pressure and performance an awn In this case, the elastic sheath 8 is sealed as a working member of plates 5 fixed by rotation, and screw 6. The bore 2 of the housing 1 is oval-shaped, and the package 4 of plates 5 is made with a common oval boring 7 in which the screw 6 is installed and provided with a sealed elastic sheath 8 attached to housing 1. The large axes 9 and 10, respectively, of the oval bores of the stack 4 of the plates 5 and the housing 1 are mutually perpendicular.
