Compressor Oil Supply Chamber With Vortex-Assisted Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil supply devices for compressors face inefficiencies in lubricating oil suction due to the need for lubricating oil to overcome its own gravity when moving vertically, leading to reduced efficiency in oil supply.
Innovation Solution
The oil supply device features a horizontally extending oil intake chamber with an oil inlet on the side wall and an oil outlet on the bottom wall, utilizing an arcuate flow guide to create a vortex and enhance oil suction efficiency, along with a partitioned oil intake and discharge chamber system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the oil supply device uses a vertical pipeline to draw lubricating oil from below, then the structure is simple, but the oil suction efficiency is poor because the lubricating oil must overcome its own gravity to move upwards
Solution Approach 1:
The patent changes the oil intake chamber from a vertical orientation to a horizontal orientation. The oil inlet is positioned on the side wall and the oil outlet on the bottom wall, allowing oil to flow horizontally into the chamber and then exit downward, eliminating the need for oil to overcome gravity to enter the chamber.
Solution Approach 2:
The patent introduces an arcuate flow guide portion with a curved surface that guides oil flow from the inlet to the outlet. This curved structure creates a vortex flow pattern that enhances the adsorption capacity at the oil inlet and accelerates oil entry into the inner chamber, improving suction efficiency.
2Productivity
If the oil intake chamber is positioned vertically with the oil suction port facing downward, then the installation is simple, but the adsorption capacity at the oil inlet is weak
Solution Approach 1:
The patent repositions the oil intake chamber horizontally rather than vertically, with the oil inlet on the side wall and oil outlet on the bottom wall. This dimensional change allows the arcuate flow guide to effectively create a vortex that enhances adsorption capacity at the inlet.
Solution Approach 2:
The arcuate flow guide portion with its curved surface is specifically designed to generate vortex flow. This curvature creates centrifugal forces that enhance the adsorption capacity at the oil inlet, allowing the chamber to draw oil more effectively from the compression chamber.
