Description

The invention relates to the field of pumping and can be used for pumping liquids and gases.

The purpose of the invention is to increase efficiency and reliability by reducing mechanical and disc friction and simplifying the design.

FIG. 1 shows a pump in operation, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

The pump contains an actuator, housing 1, mounted in the latter with the possibility of rotation of a hollow rotor 2, partially filled with a working medium (in the drawing., Indicated by vertical bars), having a density greater than the density of the pumped medium (in the drawing -.

is also indicated by the horizontal stroke-, mi), and the disk 3 placed in the cavity of the rotor. 2. The pump also comprises a shaft 4, by means of which the rotor 2 is connected to the drive and the disk 3, and the inlet and outlet channels 5 and 6, the first of which is made along the axis of rotation. The drive is made in the form of an uneven rotation mechanism, the cavity of the rotor 2 is filled closed, the disk 3 is placed. in the latter, with the formation of working and supplementary chambers 7 and 8, the latter of which is filled with working medium. On the periphery of the disk 3, holes 9 are made, communicating chambers 7 and 8. Channels 5 and 6 are located coaxially, made respectively in shaft 4, in the roto;

Claims (1)

1. A pump containing a drive, a case, installed in the last with a cart (according to the speed of any moment of operation per 10 with the possibility of rotation of a hollow rotor, coca. Any liquid that can be mixed with the pumped medium can be used as a working medium. The pump works as follows. I When the rotor 2 rotates and reaches a certain rotational speed of the working wheel, the medium under the action of centrifugal force will be forced out of the additional chamber 8 through the holes 9 into the working chamber 7, forming a liquid ring in it - l 1ch its width, with increasing number of revolutions In this case, the medium will be displaced from the working chamber of the pumping unit. b by the medium (by increasing the volume of the peg of the latter) into the discharge channel 6 through valve 1, 15 20 25 a disk filled in a rotor cavity, a shaft through which the rotor is connected to a drive and a disk, and inlet and outlet channels, the first of which runs along its axis of rotation, This means that, in order to increase efficiency and reliability by reducing mechanical and disc friction and simplifying the design, the drive is built in the form of an uneven rotation mechanism, the rotor cavity is closed, the disk is placed in the last By calling the working and additional chambers, the last of which is filled with the working medium, there are holes on the periphery of the disk, which communicate these chambers, and the inlet and outlet channels are coaxially located. filled respectively in the shaft, in the rotor and the body, connected to the working chamber and equipped with non-return valves thirty i With a subsequent decrease in the number of rotor rods 2 and a decrease in the center of the working medium, the working medium is discharged into the additional chamber B through the opening 9. In this case c. Working chamber 7 is under negative pressure, and pumped 35 through supply channel 5 and kla ™ daH 10 is sucked into working chamber 7. Then the cycle repeats. . The capacity and pressure of the pump can be changed by changing the ratio of the densities of the working and pumped medium, changing the speed, the size of the chambers 7 and 13. The formula of the invention 1. A pump containing a drive; Pus installed in the last w a disk filled in the cavity of the rotor, a shaft through which the rotor is connected to the drive and the disk, and the inlet and outlet channels, the first of which runs along the axis of rotation, o It is due to the fact that, in order to increase efficiency and reliability by reducing mechanical and disc friction and simplifying the design, the drive is integrated as an uneven rotation mechanism, the rotor cavity is closed, the disk is placed in last By calling the working and additional chambers, the last of which is filled with the working medium, there are holes on the periphery of the disk, which communicate these chambers, and the supply and discharge channels are coaxially, filled, respectively, in the shaft, in the rotor and housing chamber and are equipped with check valves. 2 about the pump. according to claim 1, about tl and h and y - y and i with the fact that additional and working KaiMepb. supplied with radial partitions. . / Pamac razEeE eni Lr y. mediums / 3 Fi, 2.
