Compressor Pulsation Damper with Parallel Flow Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displacement-type gas compressors experience pressure pulsations due to their cyclic operation, leading to incidental forces that reduce operational life and increase maintenance requirements.
Innovation Solution
A damper system comprising an outer and inner chamber with partitions dividing the outer chamber into sections, forming manifolds that create parallel flow paths, and a perforated damper plate to dissipate pressure pulsations, with a two-stage configuration to handle partially and fully compressed air effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple single-chamber damper is used, then the device complexity is low, but the pulsation reduction effectiveness is insufficient
Solution Approach 1:
The damper is divided into multiple chambers (first chamber and second chamber) separated by partitions. Each chamber contains flow paths that are segmented into multiple parallel channels, allowing the pulsation reduction function to be distributed across multiple independent flow paths, thereby improving effectiveness while maintaining manageable complexity
Solution Approach 2:
The patent introduces a multi-dimensional flow path configuration where flow is distributed across multiple parallel channels in both the first and second chambers. This dimensional expansion from a single flow path to multiple parallel paths increases the surface area for pulsation dissipation and improves overall effectiveness
2Reliability
If multiple partitions are added to divide the outer chamber, then the pulsation reduction effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
The outer chamber is segmented into multiple sections using partitions that extend from the inner chamber wall to the outer chamber wall. These partitions create multiple independent flow paths that are easier to manufacture as separate components that can be assembled together, rather than requiring a complex monolithic structure
Solution Approach 2:
The partitions are positioned such that the inner chamber is nested within the outer chamber, with the partitions extending between these two chambers. This nested configuration allows the partitions to be manufactured as integrated components or separate elements that fit within the existing chamber structure, simplifying the manufacturing process
3Duration of action of stationary object
If a two-stage damper configuration is used, then the operational life enhancement is improved, but the device complexity increases
Solution Approach 1:
The damper is segmented into two functional stages: a first chamber for handling partially compressed air and a second chamber for handling fully compressed air. Each stage operates independently to reduce pulsations at different compression stages, thereby extending operational life through targeted pulsation management at critical points in the compression process
Solution Approach 2:
The first chamber performs preliminary pulsation reduction on partially compressed air before it enters the second chamber. This preliminary action prepares the flow for further processing in the second chamber, ensuring that pulsations are reduced progressively through both stages rather than requiring a single complex stage
