Centripetal turbine axial force adjusting device

Abstract

The invention provides a centripetal turbine axial force adjusting device. The centripetal turbine axial force adjusting device comprises a shell, a main shaft, a turbine, a volute and a flow guide cone. One end of the turbine is combined with the volute and the main shaft to form a low-pressure area A. The other end of the turbine and the volute are combined to form a high-pressure area B. The turbine, the shell and the flow guide cone are combined to form a secondary high-pressure area C. As the turbine expands to do work, a first fluid medium located in the high-pressure area B enters the low-pressure area A. A second fluid medium in the high-pressure area B enters a secondary high-pressure area C. A volute through hole is formed in the end, close to the low-pressure area A, of the volute. A shell adjusting hole is formed in the end, close to the secondary high-pressure area C, of the shell. A flow adjusting assembly is arranged on the shell adjusting hole and used for adjusting andcontrolling the flow of the second fluid medium, entering the low-pressure area A, in the secondary high-pressure area C. The flow adjusting assembly is additionally arranged on the shell adjusting hole, so that the exhaust flow is controllable, the operation stability of a unit is enhanced, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of centripetal turbine structures, in particular to a centripetal turbine axial force adjustment device. Background technique [0002] In the existing centripetal turbine device, the fluid medium enters from the inlet of the centripetal turbine, a part of the fluid medium pushes the turbine to do work, and the other part of the medium flows to the sub-high pressure area near the inlet as the turbine expands to do work, so that The gas pressure in the sub-high pressure zone acts on the cover plate on the left side of the turbine, generating a rightward axial thrust. The fluid medium located in the sub-high pressure zone flows into the low pressure zone through the connected holes, which will reduce the pressure difference on both sides of the turbine, thereby achieving the purpose of reducing the axial force. [0003] However, due to the uncontrollable exhaust flow from the sub-high pressure area to the low ...
