Abstract

The invention makes it possible to increase the power and productivity of a peristaltic pump. In the housing 1 is installed elastic hose 2, interacting with a flexible rotor. Inside the rotor there is an electromagnetic actuator 4, made in the form of dual sets of magnetic cores with peripheral windings installed with the possibility of relative movement on the guiding elements 5. Winding included through one into two groups. One group is connected to a constant source, the other - to a source of alternating multiphase voltage. Elements 5 are made in the form of flexible rings, magnetic cores in the form of ferromagnetic plates located radially on them. Changes in the lengths of the core sets around the circumference lead to an elliptical deformation of the rotor. 7 il.

1 The invention relates to pump construction, peristaltic pumps HI can be used in various industries of the national economy for pumping fluids.

The purpose of the invention is to increase the power and performance of the pump. FIG. 1 shows the proposed, section by plane, perpendicular to the axis of the axis; on fig | 2 - the same, a section by the radial plane; FIG. 3 shows a rotor, a plane cut, a perpendicular to the n-axis; FIG. 4 is the same, the section of the wounds of other cores 6 (installed through one) periodically attracts - pushing away cores 6 in sets and periodically changing the lengths of sets of cores 6, Since sets of cores 6 are connected in pairs (oppositely arranged sets) to different the phases of a multiphase source of alternating voltage, the change in the lengths of the opposite-set sets and the rotation of the deformation wave of sets of cores 6, the change in the length of the dipole plane; in fig. 5 - fragments of 5 sets of cores around the circumference

pump coupling, operating condition at one nrm from rotor positions; Fig, 6 - the same, with a different position of the rotor; Fig, 7 is a diagram of the electrical connections of the windings.

The pump includes a housing 1 in which an elastic hose 29 is inserted, which is borrowed with a flexible rotor 3. It has an electromagnetic actuator 4 placed inside it, made in the form of installed with the possibility of backward movement in the directions 5 three dual sets of magnetic hearts u

The guiding elements 5 are made in the form of flexible wheels. magnetic cores 6 - in the form of ferromagnetic plates located radially on them,

When a constant and alternating voltage is applied to groups 8 and 9 of the windings 7 due to alternating switching on of the windings, constant magnetization of one core 6 and remagnetization 35

at least three dual sets of magnetic cores with peripheral windings connected through one into two groups, one of which is connected to a constant source and the other to a source of alternating multiphase voltage, characterized by In order to increase power and productivity, the guide elements are made in the form of flexible rings, and the magnetic cores in the form of ferromagnetic plates located radially on them.

No other cores 6 (installed through one) periodically attracts - pushing away cores 6 in sets and periodically changing the lengths of sets of cores 6, Since sets of cores 6 are connected in pairs (opposite sets) to different phases of a multiphase AC source, then the change in the lengths of the oppositely installed sets and the rotation of the deformation wave of the sets of cores 6, the change in length leads to an elliptical deformation of the flexible rotor 3. With its large diameter meter rotor 3 presses the hose 2 and moves through it the pumped medium to the consumer.
