Turbo Compressor Housing Welded Segmentation for Coating Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high production and material costs associated with turbo compressor housings suitable for handling corrosive gases, particularly due to the difficulty in accessing and coating the interior surfaces, necessitate a more efficient and automated method for creating a corrosion-resistant housing.
Innovation Solution
A turbo compressor housing design with a corrosion-inhibiting coating only in the inflow section, where the medium is most corrosive, and a weld seam through the wall thickness between the inflow and outflow sections allows for automated coating and independent selection of coating and welding materials, enhancing accessibility and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire housing is made from corrosion-resistant material, then corrosion protection is improved, but production costs and material costs increase
Solution Approach 1:
The patent applies a corrosion-inhibiting coating only to the inflow section of the housing where the medium is most corrosive, rather than coating the entire housing. This localized approach reduces material costs and production expenses while maintaining adequate corrosion protection in the critical area.
2Reliability
If the interior surface of the turbo compressor housing is coated with corrosion-resistant material, then corrosion protection is improved, but accessibility for coating becomes difficult and automation is reduced
Solution Approach 1:
The housing is divided into two separate axial sections (inflow section and outflow section) that are joined by a weld seam. This segmentation allows the inflow section to be accessed and coated independently from the outflow section, enabling automated coating processes without requiring access to the entire housing interior.
3Ease of manufacture
If the inflow section and outflow section are separated by a weld seam, then accessibility for coating is improved and material selection independence is enhanced, but device complexity increases
Solution Approach 1:
The housing is segmented into two axial sections joined by a circumferential weld seam, which facilitates independent coating of the inflow section and allows separate material selection for different housing parts.
Solution Approach 2:
A sealing element is introduced as an intermediary component between the inflow and outflow sections to prevent mixing of fluids with different pressures. This sealing element compensates for the complexity introduced by the segmented structure while maintaining functional integrity.

AI summary
The invention relates to a turbocompressor housing (TCC) which extends along a longitudinal axis (X). The turbocompressor housing (TCC) has an inflow (INL1) in an axial inflow section (INA1) leading into an interior (CAC) and an outflow (EXT) in an axial outflow section (EXA1) leading out of the interior (CAC). The invention is characterized in that the turbocompressor housing (TCC) is welded on a radial separating plane (SPL) between the axial inflow section (INA1) and the axial outflow section (EXA1) by means of a welding seam (WSE) which extends in the circumferential direction and through the wall thickness. The interior (CAC) of the inflow section (INA1) is at least partly provided with a coating (CLD) in a coated region (CLA).
