SU1370308A1 - Shaftless pump - Google Patents

Abstract

The invention allows to expand the field of application of the pump by allowing pumping of non-destructive liquids, their structure, and to regulate the flow rate by changing the gap between the discs. Each of the housing parts 1.2 is provided with a support surface 9, 10 on which disks 5, 6 are installed with a uniform axial clearance. The parts of the housing are interconnected with the possibility of axial movement. Changing the gap between the discs is achieved by unscrewing part 1 of the housing from part 2, which leads to a change in the fluid flow rate and allows, depending on the viscosity of the pumped liquid, to select the optimal flow rates and thereby increase the efficiency of the pump. When pumping liquids with such a pump, the perturbation of the flow is reduced due to the absence of pump elements in it that are located across the flow, as a result of which the liquid is reduced. 1 il.

Description

The invention relates to pump construction and can be used in various technological processes for pumping liquids, the destruction of the structure of which must be avoided, for example, blood, water, etc.

The purpose of the invention is to expand the field of application by allowing the pumping of liquids that do not allow destruction of their structure, and controlling the flow rate by changing the gap between the disks.

The drawing shows a limp pump, a longitudinal cut.

The shaftless pump comprises a housing made of two interconnected parts 1 and 2, equipped with inlet and outlet pipes 3 and 4, and two disks 5 and 6 mounted in the housing so that they can be rotated and with a gap relative to the other. and 8, placed in different parts 1 and 2 of the case. Each of the housing parts 1 and 2 is provided with a supporting surface 9 and 10. The disks 5 and 6 are mounted on the supporting surfaces 9 and 10 by means of bearings 11 and 12 and with a uniform axial clearance. Parts 1 and 2 of the housing are interconnected with the possibility of axial movement, for example, by means of a threaded joint 13.

Pumpless pump works as follows.

The disks 5 and 6, which are the rotors of the inductors 7 and b, rotate under the deuterium of the pulsed magnetic flux created by the excitation windings of the inductors 7 and 8 as the alternating current passes through them. Fluid through inlet pipe 3

In the opposite direction, the centrifugal si pus is thrown to the periphery of the disks 5 and 6 and is led out of the pump through the outlet 4.

The change in the gap between the disks 5 and 6 is achieved by screwing (unscrewing) part 1 of part 2 of the housing, which leads to a change in the fluid flow. Adjusting the gap between the discs 5 and 6 allows, depending on the viscosity of the pumped liquid, to select the optimal flow rates and thereby increase the efficiency of the pump.

When pumping liquids with an inertial pump of the proposed design, the disturbance of the flow is reduced due to the absence of pump elements in it that are located across the flow of the liquid.

Invention Formula A shaftless pump comprising a housing made of two interconnected parts, provided with inlet and outlet pipes, and mounted in the housing rotatably and with a gap one relative to the other two disks, which are driven by inductors placed in different parts of the housing, differing in the fact that, in order to expand the scope of application by allowing the pumping of liquids that do not allow the destruction of their structure, and controlling the flow rate by changing the gap between the discs, each stey housing provided with a support surface, supporting wheels mounted on the surfaces with a uniform axial gap, and the body portion are connected together with into the gap between the rotating disks 5 and 6, the battle with the possibility of axial reversing is carried away by the forces of friction in the field.
