The invention has the advantages of small error and high precision.

Description

technical field [0001] The invention relates to the technical field of turbine processing; in particular, it relates to a processing method for a turbine of an ORC expander power generation device. Background technique [0002] In recent years, encouraged by the country's vigorous development of clean energy policies and the support of national industrial policies, the ORC expander power generation device has a broader market. The turbine is a key part of the ORC expander power generation device, and its processing quality directly affects the working efficiency of the ORC expander power generation device. The turbine is connected with the main shaft and rotates together with the main shaft, thereby compressing air and improving work efficiency. [0003] The turbines currently used in the market are generally in the form of a double-channel structure, which solves the problem of turbo lag. The turbo with double-channel structure divides the intake pipe of the turbine into ...

AI Technical Summary

Problems solved by technology

When machining a turbine with a double-channel structure, it is necessary to take into account the design requirements of the flow channels on both sides, so the machining of a turbine with a double-channel structure is difficult and technically difficult

[0004] In terms of turbine material, since this turbine uses 17-4PH (0Cr17Ni4Cu4Nb), the cutting performance of this material is poor

When milling the flow channel, solid carbide tools are generally used for processing, but due to the poor cutting performance of this material, it is not only difficult to process the flow channel with conventional tools, but also causes serious wear and tear on the tool and low efficiency , it is difficult to meet the technical requirements

The working requirements of the turbine with a double-channel structure make the processing requirements of the two channels high, but the current method of machining the turbine flow channel uses multiple benchmarks, resulting in large errors and seriously affecting the use of the turbine with a double-channel structure
