Air Compressor Balance Adjustment Using Intermediate Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air compression devices face a trade-off between reducing residual unbalance and increasing processing costs due to the need for extensive balancing adjustments, which can lead to higher man-hours and costs.
Innovation Solution
An air compression device with a motor, a multiblade fan rotating integrally with the rotor, and an intermediate balance weight that includes balance adjusting units, allowing for simultaneous adjustment of the rotor, fan, and intermediate member to reduce total unbalance while minimizing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the rotor, first fan, and second fan are individually subjected to balance adjustment processing, then the residual unbalance amount of each member is reduced, but the total residual unbalance amount increases due to accumulation of residual unbalance
Solution Approach 1:
The patent merges the balance adjustment of the rotor, first fan, and second fan into a single integrated balance adjustment process. The intermediate member serves as a common base for all three components, allowing their balance to be adjusted simultaneously rather than individually, thereby preventing the accumulation of residual unbalance amounts.
Solution Approach 2:
The intermediate member acts as an intermediary component that facilitates the integrated balance adjustment. It provides a common reference base for the rotor and fans, enabling the balance inspection device to measure and adjust the total unbalance amount of all rotating components together.
2Reliability
If further adjustment processing is performed on each member to reduce total residual unbalance amount, then the total residual unbalance amount is reduced, but the man hours for adjusting balance increase
Solution Approach 1:
The patent combines multiple balance adjustment operations into a single integrated process. By adjusting the balance of the rotor, first fan, and second fan simultaneously on the common intermediate member base, the total man hours required are significantly reduced compared to performing adjustments individually for each component.
Solution Approach 2:
The intermediate member is designed with predetermined balance adjusting units that can be modified in a single adjustment process. This preliminary design allows for the balance of all rotating components to be optimized simultaneously without requiring multiple separate adjustment operations.
3Ease of operation
If balance adjustment processing is performed on each component separately, then each component achieves acceptable balance, but the cumulative effect increases total unbalance and requires more processing time
Solution Approach 1:
The patent merges the balance adjustment operations for the rotor and fans into a single integrated process on the common intermediate member. This approach maintains the ease of adjusting individual components while significantly improving overall processing efficiency by eliminating redundant adjustment steps.
