Description

one

The invention relates to mechanical engineering, in particular to rotary machines.

A rotor machine is known, comprising a housing with a stator accommodated therein, a rotor made in the form of two pairs of segments, each of which is mounted on its axis through rolling bearings, end caps, inlet and outlet nozzles and mechanism: movement of the segments.

A disadvantage of the known rotary machine is the low reliability of operation.

The purpose of the invention is to increase the reliability of work.

This goal is achieved by the fact that the mechanism for moving the segments is made in the form of springs placed in the cavities between the segments and permanent magnets installed at the attachment points of the exhaust nozzles displaced by an angle of 90 relative to the inlet jiaTpy6kov, segments Made of soft steel from a non-magnetic material, and cTatop is provided with grooves in which an electrical winding is placed ...

Figure 1 shows a rotary machine, cross section; Fig.2 section bb in Fig.1.

The rotor machine comprises a housing 1 in which a stator 2 is placed, in the slots 3 of which the electric winding 4 is placed, a rotor made in the form of segments 5–8 made of magnetically soft steel and shifted relative to each other at an angle of 90, and the segments located on opposite sides of the axis

9 rotors are rigidly interconnected and form two pairs 5.7 and 6.8,

The housing 1 is closed with end caps 14, which are made of a non-magnetic material and are equipped with exhaust nozzles 15, located

25 on opposite sides with respect to the axis 9. At the points of attachment of the outlet nozzles 15, fixed 16 and 17 are mounted, forming with the brigades 13 a mechanism for moving the segments 5-8. Inlets 18

bomes concerning exhaust at an angle of 90

Rotary machine in pump mode works as follows.

When the winding 4 is connected to the source, a three-phase voltage is created at the moment of protection, and the segments 5.7 and 6.8 begin to rotate. Under the influence of the permanent magnets 16 and 17, pairs of 5.6 and 7.8 segments are attracted to each other, and the volume of the cavities 11 begins to decrease, and the volume of the cavities 12 increases, i.e. the process of injection and suction occurs. The maximum compression and expansion of the cavities is achieved when the rotor is rotated through an angle of 90 °. When pairs 5, 7 and 6, 9 of the segments are rotated by 180 °, the attractive force of the permanent gadgets 16 and 17 is equal to nyijKf and the pairs of 5.7 and 6.8 segments occupy a neutral position. When the rotor is rotated through an angle of 180 ° to 270, the suction and injection processes are similar to those of suction and pressure when the rotor is rotated through an angle of 0 ° to 90 °. With a further turn from 270 ° to 3%, the segments occupy a neutral position. The highest performance and maximum efficiency is obtained in the resonant case, when the natural frequency of the torsional vibrations of the elastic system: segment 5 - spring 13 - segment 6 is twice the angular velocity.

The technical and economic effect is to increase the service life of the rotary machine by 2-3 times due to the exclusion of friction between the moving parts.
