Two-Stage Turbo Compressor U-Pipe Layout for Lower Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-stage turbo compressors face issues with increased pressure loss due to complex and long piping structures, which disrupt fluid flow and limit the efficiency of pressure energy conversion, especially when the impellers are connected via external or internal piping.
Innovation Solution
A two-stage turbo compressor design featuring a U-shaped pipe connecting the discharge port of the first compression stage to the suction port of the second compression stage, with a semi-circular arc bend and external piping, minimizing fluid separation and pressure loss while ensuring sufficient space for a diffuser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external piping is used to connect the first and second impellers, then the impellers can be positioned at opposite ends of the drive motor shaft, but the piping structure becomes long and complicated, causing increased pressure loss
Solution Approach 1:
The piping structure transitions from a three-dimensional complex routed path to a simplified configuration where the first and second impellers are positioned in the same plane, reducing the piping to essentially a two-dimensional U-shaped connection with minimal bends
2Length of moving object
If internal piping is used within the housing to connect the impellers, then the distance between impellers can be shortened, but the piping curvature becomes small causing separation and increased pressure loss
Solution Approach 1:
The piping is extracted from the internal housing structure and repositioned externally, allowing the piping to be configured as a U-shaped pipe with large curvature radius that connects impellers in the same plane, avoiding the small curvature constraints of internal housing piping
3Device complexity
If internal piping with small curvature is used, then the piping can be contained within the housing, but fluid separation occurs and pressure loss increases
Solution Approach 1:
The piping configuration moves from internal containment to external arrangement in the same plane, transforming the piping from a constrained three-dimensional internal route to an optimized two-dimensional U-shaped external connection with sufficient curvature

AI summary
A turbo compressor is provided with a first compression stage that draws in and compresses a fluid, and a second compression stage connected to the first compression stage via a rotation shaft, that further compresses the compressed fluid from the first compression stage. The first compression stage and the second compression stage are arranged adjacent to each other with their backsides facing each other. A discharge port of the first compression stage, and a suction port of the second compression stage are formed in the same plane, and there is provided a U-shaped pipe that connects the first discharge port and the second suction port.
