Abstract

The invention discloses a high-efficiency titanium alloy impeller of a centrifugal compressor and a finishing method, including an impeller base, a first bolt, an elastic gasket, a mounting plate, a limiting plate, a first chute, a limiting block, a rotating shaft, Spring, gear, gear ring, limit claw, second chute, input port, limit sleeve and protective coating; finishing method, including step 1, inner hole processing; step 2, blade processing; step 3, polishing Processing; step four, protective layer spraying; step five, inspection and storage; the invention is safe and reliable, through the first bolt, elastic gasket, mounting plate, limit plate, chute, limit block, rotating shaft, spring, The cooperation of the gear, the gear ring, the limit claw and the chute, through the stable engagement structure, facilitates the stability of the installation of the impeller; and through the fine turning method, the step of spraying the protective layer is added, which is convenient for production and processing of an integrally formed , The impeller with good mechanical performance is convenient for enterprises to promote and use.

Description

High-efficiency titanium alloy impeller of centrifugal compressor and finishing method technical field The present invention relates to centrifugal compressor equipment technical field, be specially the high-efficiency titanium alloy impeller of centrifugal compressor and finishing method. Background technique The impeller in the centrifugal compressor is an important component in the centrifugal compressor, therefore, the market for a There are certain requirements for high-efficiency titanium alloy impellers and finishing methods of some centrifugal compressors; however, the existing centrifugal compressors When the titanium alloy impeller used in the compressor is installed, most of them only use interference fit connection or direct bolt connection. The connection method is relatively simple, but it is not stable enough, which affects the service life of the titanium alloy impeller; and the precision turning of the existing titanium alloy impeller The processin...
