Abstract

DC60 (08/02/54) Squirrel-cage turbine vacuum pump incorporating a cutout section. Where each part Of it will attach the connector to the The closure of the groove of the turbine coupled with the oil is arranged in such a way that it extends into the region close to the surface along the periphery of the rotor and will provide at least part of the surface. Along the edge Around the outside on the inside side The direction of rotation of the rotor And it will have a shape that is concave or squeezed along the radial cutout, each part has a concave shape, which is used in such a way that Its radial size will It is reduced with an increase in distance in the circumferential direction from 15 adjacent openings and is arranged in such a way that it faces the near Close to the dead center D and will extend Out through the entire axial length of the squirrel cage turbine vacuum pump rotor consisting of a cutout section Where each part Of it will attach the connector to the Close of the groove of each other turned to match with it that was Set it up In such a way that it joins in a region close to the surface along the periphery of the rotor and to have at least part of the surface along the periphery. Around the outer circle on the inner side The direction of rotation of the rotor, by which it will have a shape that is concave or squeezed in line with a circle, each part of the cutout has a concave or compressed shape which is used in the That its size along the circle will decrease with Increase of distance in the direction along the edge around the circle from the segment. Of the adjacent opening 15 and will be positioned in such a way that it faces near It corresponds to dead center D and is present across the entire axial length of the rotor.

Claims (5)

1.Squirrel-cage turbine vacuum pump Where it consists of a cylindrical body at the bottom, an upright rod rotor that is It is indented in such a frame, turbines that each rotate in such a way that they are attached in a movable manner. On the surface along the edge Surrounding the inside of the said body And simultaneously with Sa The lubrication is delivered into the body as well. By movement In the same manner as in and out in the circular direction of such rotor, when the said rotor is rotated, the suction inlet at which the The flow is sucked in and the vent, from which the fluid rubbed The suction will be drained together with the lubricant by pumping such a cut-out part. Where each part of it will attach to the connector Attached to the channel part This groove is arranged in such a way that it connects to the surface close to the surface along the periphery of the rotor, and will Was placed on the side In the direction of rotation of the said rotor It will have a shape that is concave or compressed along a circle. 2. Squirrel-cage turbine vacuum pump as described in Clause 1, where each section of such cut-out is either concave or bumped by the size according to Its circle will decrease with increasing Up of the distance in the direction along the edge around the circle from Part of the opening like 3. Squirrel-cage turbine vacuum pump as described in Clause 1 or 2, where each such cut-out section is provided in a manner that Continued throughout the process Length in all axes of such rotor 4. A cylinder-cage turbine vacuum pump as described in Clause 1 to 3, one where the vent is positioned laterally in the direction of the request. The rotor 5. Squirrel-cage turbine vacuum pump as described in any Clause 1 to 4 - one where each such cut-out part is positioned in the area where Which part of the cutout As mentioned, each part will face into the It coincides with the dead center located in the direction of rotation of the turbine, to the point at which the turbine ends up passing by the shaft. The drain in the rotating direction located on the surface along the edge, waiting On the outside of the rotor.
