Turbo Compressor Adapter Structure for Variable Motor Casing Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In turbo compressors, changes in motor voltage require corresponding increases in motor and compressor casing sizes, leading to inventory and cost issues due to the complex shape of the compressor casing.
Innovation Solution
The use of an adapter member with different connection portions allows for the connection of compressor and motor casings of varying sizes without altering the compressor casing, utilizing seal members for airtight sealing and maintaining pressure integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the motor diameter is increased to correspond to higher voltage specifications, then the motor can accommodate higher voltage, but the compressor casing size must also be increased and inventory costs increase
Solution Approach 1:
The system is divided into three separate components: compressor casing, adapter member, and motor casing. The adapter member acts as an independent segment that bridges the size difference between the fixed compressor casing and variable motor casings, allowing motor casings of different sizes to be connected without modifying the compressor casing.
Solution Approach 2:
The adapter member serves as an intermediary component between the compressor casing and motor casing. It has a first connection portion that interfaces with the compressor casing mounting flange and a second connection portion that interfaces with the motor casing mounting flange, mediating the size mismatch and enabling connection of motors with different voltage specifications.
2Adaptability or versatility
If the compressor casing size is increased to accommodate larger motors, then higher voltage motors can be installed, but inventory locations and inventory costs are required due to the complicated shape of the compressor casing
Solution Approach 1:
The system separates the compressor casing from the motor casing connection interface by introducing an adapter member. This segmentation allows the compressor casing to maintain a fixed, optimized design while the adapter member handles the variability required for different motor sizes, eliminating the need to manufacture multiple compressor casing variants.
Solution Approach 2:
The adapter member is designed as a universal component that can interface with compressor casings of a standard size and accommodate motor casings of various sizes corresponding to different voltage specifications. This multi-functionality allows a single compressor casing design to support multiple motor voltage specifications.
3Power
If the diameter of the motor casing main body part is larger than the mounting flange diameter of the compressor casing, then higher voltage motors are accommodated, but direct connection without changing the compressor casing is not possible
Solution Approach 1:
The adapter member serves as a mediating component that resolves the diameter mismatch between the compressor casing mounting flange and the motor casing mounting flange. It provides a transition interface that enables connection between components of different sizes without requiring modification of the compressor casing.
Solution Approach 2:
The solution addresses the dimensional mismatch by introducing an intermediate component that operates in the same dimensional space but with different diameter specifications. The adapter member effectively creates a dimensional transition, allowing connection between the smaller compressor casing flange and the larger motor casing flange.

AI summary
A turbo compressor includes: a compressor casing which accommodates impellers compressing gas by rotation; and a motor casing which accommodates a motor rotating the impellers, wherein the motor casing has a cylindrical main body part having a larger diameter than a mounting flange provided in the compressor casing, and the compressor casing and the motor casing are connected through an adapter member.
