Description

Technical Field

[0001] The utility model belongs to the technical field of compressor impellers, and in particular relates to a disassembly tool for a compressor impeller. Background Art

[0002] The impeller, the core moving part of a centrifugal compressor, performs work on the gas, allowing it to gain energy and thus achieve the purpose of compressing the gas. Therefore, the quality of the impeller design plays a decisive role in the performance of the centrifugal compressor. Since the quality of the impeller's performance is mainly reflected in its aerodynamic performance, the design of the impeller's internal flow channel is particularly critical.

[0003] The existing impeller disassembly is completed by using a jackscrew while heating the impeller, that is, a matching jackscrew is installed in the threaded hole at the front end of the impeller, and the jackscrew is rotated so that the jackscrew presses against the inner shaft end of the impeller to achieve thermal disassembly of the impeller. This disassembly method does not clamp and limit the impeller during use, and it is easy to damage the impeller thread and the shaft end during rotation, and the jackscrew is easy to break, which brings trouble to the user's work. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content
