Piston Compressor End-Face Connection Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Piston compressors face challenges with large size and restricted accessibility due to the arrangement of suction and pressure connections, leading to increased costs and complexity in manufacturing and maintenance, especially at high pressures.
Innovation Solution
The suction and pressure connections are relocated to the end face of the compression cylinder, eliminating side connections and allowing for a shorter cylinder and piston design, which simplifies manufacturing and enhances accessibility in vertically arranged systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If suction and pressure connections are arranged on the side of the compression cylinder, then the cylinder can be made longer to accommodate valve chambers, but the accessibility for maintenance and pipeline routing is severely restricted
Solution Approach 1:
The suction and pressure connections are relocated from the side of the compression cylinder to the end face, changing the spatial dimension of connection arrangement. This dimensional shift allows pipeline routing without impeding support structures and provides excellent accessibility for maintenance while eliminating the need for complex side connections and covers.
2Ease of manufacture
If the compression cylinder is made longer to include side connections and valve chambers, then all gas spaces and channels can be formed, but the length increases by 20% to 30% and manufacturing costs increase
Solution Approach 1:
The connection chambers for suction and pressure connections are merged into the end face of the compression cylinder, combining multiple functions (cylinder closure, connection points, and valve chamber access) into a single structural element. This eliminates the need for separate side connections and reduces the overall cylinder length by 20% to 30%, simplifying manufacturing.
Solution Approach 2:
The connecting channels that were previously open to the side are extracted and repositioned to be closed off at the end face. This extraction eliminates the need for complex side openings and covers, reducing manufacturing complexity and cylinder length while maintaining all necessary gas flow paths.
3Weight of stationary object
If side connections are provided for suction and pressure ports, then gas flow paths can be established, but the outer dimensions and weight of the compression cylinder increase
Solution Approach 1:
By relocating connections to the end face, the patent changes the spatial arrangement from lateral extensions to axial integration, reducing the cylinder's outer dimensions and weight while improving pipeline routing flexibility through the freely accessible end face.
