Scroll Compressor Oil Tubing Assembly for Long Tube Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing oil tubing installation tools struggle to accommodate longer oil tubing lengths in compressors, making it difficult to meet the requirements of maintaining a low oil circulation rate and drawing excess oil away from the housing, as they are limited by the structural size of the tools and the residual space between the housing and mid-shell.
Innovation Solution
An oil tubing installation assembly comprising a housing with a vertical oil tubing installation surface, a clip with elastic tongues for secure alignment, and an oil tubing assembly with a cuboid-shaped installation block and orifices, allowing for easy vertical installation and secure fitting within the compressor shell, overcoming the limitations of existing tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the oil tubing length is increased to meet functional requirements, then the ability to maintain low oil circulation rate and draw excess oil away from housing is improved, but the difficulty of assembly increases due to limitations of existing assembling tools
Solution Approach 1:
The assembly process is segmented into two independent stages: (1) assembling the housing with the oil tubing installation assembly into the mid-shell, and (2) separately assembling the oil tubing into the clip within the mid-shell. This segmentation allows each stage to be optimized independently, resolving the contradiction between long oil tubing length and assembly difficulty.
Solution Approach 2:
The clip serves as an intermediary component that facilitates the assembly of long oil tubing. It provides a mounting structure on the housing that guides and secures the oil tubing, making it easier to install long tubing without requiring complex assembling tools with extended stroke.
2Length of stationary object
If the housing is raised to a certain height using an assembling tool to install the oil tubing, then the oil tubing can be placed into the mid-shell, but the stroke of the assembling tool must be increased which is limited by the structural size of the tool
Solution Approach 1:
The oil tubing installation assembly, including the clip, is pre-assembled onto the housing before installing the housing into the mid-shell. This preliminary action eliminates the need for assembling tools to raise the housing to great heights, as the oil tubing is already positioned and secured on the housing prior to final assembly.
Solution Approach 2:
The oil tubing assembly operation is extracted from the main housing assembly process. Instead of requiring the assembling tool to simultaneously handle both housing positioning and oil tubing installation, the oil tubing assembly is separated into a distinct, simpler operation that can be performed independently within the mid-shell after housing installation.
3Ease of operation
If the oil tubing is assembled separately after the housing is installed into the mid-shell, then the assembling tool stroke limitation is avoided, but the residual space between the housing and mid-shell is too small to assemble the oil tubing
Solution Approach 1:
The clip is designed to extend outward from the housing into the available space within the mid-shell, utilizing the vertical and radial dimensions effectively. This dimensional arrangement allows the oil tubing assembly to be performed in the available space without requiring excessive residual volume between the housing and mid-shell walls.

AI summary
The disclosure provides an oil tubing installation assembly and a scroll compressor adopting the same. The oil tubing installation assembly is adapted to be installed into a shell in a vertical direction and includes: a housing on which a vertical oil tubing installation surface and an oil hole located in the oil tubing installation surface are provided; a clip adapted to be installed on the oil tubing installation surface and into the shell along with the housing; and an oil tubing assembly adapted to be installed into the clip in a vertical direction after the housing and the clip have been installed into the shell. The oil tubing assembly includes an oil tubing body and a cuboid-shaped installation block. A through hole is provided in the installation block and the through hole is configured to have a first orifice on the front surface of the installation block and a second orifice on the rear surface of the installation block. The upper end of the oil tubing body is connected to the first orifice. The second orifice is aligned with and fitted to the oil hole after the installation block is installed in place in the clip. In this way, the long oil tubing can be easily installed manually in place even after the housing has been pressed into the shell.
