(54) НАСОС ПЕРИСТАЛЬТИЧЕСКОГО ТИПА(54) PERISTALTIC TYPE PUMP

Изобретение относитс к насосостроению и касаетс перистальтических насосов.This invention relates to a pump engineering industry and peristaltic pumps.

По осному авт.св. № 735824 известен насос, содержащий эластичный шланг, расположенный на опорной поверхности корпусной детали и взаимодействующий с рабочей поверхностью роликов, размещенных на роторе, причем дл уменьшени износа шланга корпусна детсшь выполнена с возможностью изменени угла наклона опорной поверхности к плоскости раще- ни ротора, а рабочие поверхности роликов выполнены коническими, и по меньшей мере две из них имеют отличную друг от друга величину конусности . При этом-корпусна деталь может быть выполнена из эластичного материала или в виде нескольких опорных элементов,.каждый из которых шарнирно закреплен в корпусе с возможностью относительного поворота в плоскости, перпендикул рной плоскости вращени ротора 1 .By axle auth. No. 735824 is known a pump comprising an elastic hose located on the supporting surface of the body part and cooperating with the working surface of the rollers placed on the rotor, and to reduce the wear of the hose, the body of the child is made with the possibility of changing the angle of inclination of the supporting surface to the rotor plane and the surfaces of the rollers are tapered, and at least two of them have a different taper value. In this case, the body part may be made of an elastic material or in the form of several supporting elements, each of which is hinged in the body with the possibility of relative rotation in a plane perpendicular to the plane of rotation of the rotor 1.

Недостатком известного насоса вл етс некоторый износ шланга изза того, что ролики с конической поверхностью частично проскальзывают по илэнгу вследствие различи The disadvantage of the known pump is some wear of the hose due to the fact that the rollers with a conical surface partially slip along the ileng due to the difference

диаметров качени по ширине ролика при одинаковой его угловой скорости в разных сечени х.rolling diameters across the width of the roller at the same angular velocity in different sections.

Цель изобретени - уменьшение износа шланга.The purpose of the invention is to reduce hose wear.

Поставленна цель достига-етс тем, что каждый ролик образован набором дисков различного диаметра, установленных с возможностью свободного The goal is achieved by the fact that each roller is formed by a set of disks of different diameters, installed with the possibility of free

10 вращени один относительно другого.10 rotations relative to each other.

При этом каждый диск, кроме кра.йних , имеет равномерно расположенные по поверхности отверсти , заполненные смазкой.In addition, each disc, except for the edge of the bottom, has evenly spaced holes on the surface, filled with grease.

Кроме того, каждый набор дисков снабжен пружинной шайбой дл поджима дисков.In addition, each set of disks is provided with a spring washer for pressing the disks.

На фиг. 1 представлен насос, продольный разрез; на фиг. 2 - попереч20 ный разрез насоса по ролику; на фиг. 3 - диск, вид в плане.FIG. 1 shows a pump, a longitudinal section; in fig. 2 is a cross section of the pump along the roller; in fig. 3 - a disk, a plan view.

Claims

The pump casing 1 contains a rotor 2 with rollers .3 and an elastic hose 4 laid on the supporting surface 5 of the body part 6 made with the possibility of changing the angle of inclination of the supporting surface 5 to the plane of rotation of the rotor 2. The working surfaces 7 of the rollers 3 are made conical and at least two of them have a different taper value. In addition, each roller is formed by a set of disks 8 and 9 of different diameters, installed with the possibility of free rotation one relative to another. Each disc 8, except for the outermost 9, has evenly spaced holes 10 on the surface, filled with grease. In addition, each set of disks 8 and 9 is provided with a spring washer 11 for pressing the disks 8 and 9. In the particular case, the working surface 7 of some rollers 3 can be made with zero taper, i.e. cylindrical. Body part 6 may be made of elastic material. When the rotor 2 rotates, the rollers 3 roll over the hose 4, moving the pumped liquid to the consumer along rifeMy. In the process of deformation of the hose with 4 different rollers 3, the plane of clamping of the hose 4 and the places of bending of its walls vary. This reduces the wear of the walls of the hose 1 at the points of inflection. In addition, when rolling the rollers 3 along the trunk 4, each disk 8 and 9 rotates independently of the other without slipping through the hose 4, which increases its eternity. Thus, due to the independent rotation of the disks 8 and 9, the wear of the hose 2 is reduced. The lubricant in the holes 10 of the disks 8 reduces the friction between the disks, and the spring washers 11 press the sets of disks 8 and 9, preventing the formation of gaps between them, in which hose 4 may be trapped and through which lubrication may be dislodged. Claims of invention 1. Peristaltic type pump according to auth.St. 735824, characterized in that, in order to reduce the wear of the hose, each roller is formed by a set of disks of different diameters, installed with the possibility of free rotation one relative to another.

2. The pump according to claim 1, which means that each disc, except the extreme ones, has evenly spaced holes on the surface, filled with grease.

3. Pump of Claims 1 and 2, characterized in that each set of disks is provided with a spring washer for pressing the disks. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 735824, cl. F 04 B 43/12, 1977.
