Reciprocating Compressor Connector Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reciprocating compressors face issues with the unstable coupling of discharge hoses and discharge pipes, leading to damage from high temperatures and refrigerant leaks due to loose connections and the use of plastic connectors that are prone to damage and strength reduction.
Innovation Solution
A reciprocating compressor design that stabilizes the coupling of discharge hoses and discharge pipes using a connector with ring members and a clamp system, eliminating the need for a caulking process and preventing refrigerant leaks by ensuring secure attachment without deforming the discharge pipe end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the discharge hose is coupled to the discharge pipe using a plastic connector, then the assembly is easy to manufacture, but the connector may be damaged by high temperature and pressure, leading to loose coupling and refrigerant leakage
Solution Approach 1:
The patent replaces the durable but complex metal connector with a simpler, more economical plastic connector that is designed to be replaced if damaged. This resolves the contradiction by accepting the shorter service life of plastic components in exchange for significantly improved ease of manufacture and reduced cost, while maintaining adequate reliability for the application.
Solution Approach 2:
The patent modifies the physical parameters of the plastic connector by selecting materials with appropriate temperature and pressure resistance characteristics. By carefully choosing plastic materials that can withstand the specific operating conditions of the discharge hose assembly, the patent achieves both ease of manufacture and sufficient reliability without requiring metal components.
2Stability of the object's composition
If the end of the discharge pipe is deformed to prevent connector separation, then the coupling stability is improved, but the strength of the discharge pipe is reduced, leading to potential refrigerant leakage
Solution Approach 1:
The patent introduces a clamp as an intermediary component that provides the necessary coupling stability without requiring deformation of the discharge pipe. The clamp acts as a mediator between the connector and the discharge pipe, securing the connection while preserving the full strength of the pipe. This resolves the contradiction by achieving stable coupling through an external fastening mechanism rather than compromising the pipe's structural integrity.
3Ease of operation
If the discharge hose is not stably coupled, then the assembly is easy to install, but the discharge hose moves and contacts the high temperature housing shell, causing damage and refrigerant leakage
Solution Approach 1:
The patent applies preliminary anti-action by pre-positioning the discharge hose in a stable, fixed configuration using the connector and clamp assembly before the system operates. This preliminary stabilization prevents the hose from moving into contact with the high-temperature housing shell during operation, thereby preventing damage while maintaining ease of installation through the simple connector design.
