DEVICE FOR BALANCE OF ROTOR AXIAL PRESSURE OF TURBOMACHINE Russian patent published in 2018 - IPC F01D3/04 

FIELD: machine industry.

SUBSTANCE: device for balancing the axial pressure of the rotor of the turbomachine comprises a hollow body and a disk disk mounted in the body with a central shaft and dividing the body into two cavities with channels for supply and discharge of compressed air to each hollow. One end of the shaft is provided with a central threaded socket, and both ends of the shaft – with external splined flanges. Disk piston is installed in the body on roller bearings and is provided with seals on the supports and the outer diameter of the piston. In the hollows of the device there are annular water heat exchangers with the supply and discharge of water. Displacement sensor is mounted on the body of the device with the ability to control the axial position of the piston and is electrically connected to the control unit. Axial pressure created on the piston is transferred to the rotor of the turbomachine. Rotating disk piston heats the compressed air around it due to frictional forces. Heated air transfers heat to water heat exchangers, which reduces the temperature of the device.

EFFECT: invention is aimed at increasing the heat removal from the disk piston and the hollow body of the balancing device.
