Multi-Stage Lubricating Oil Tank for Fast Air Bubble Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricating oil tanks struggle to efficiently and accurately remove air bubbles from recycled lubricating oil in a short time, leading to potential impairment of lubrication performance and requiring larger tank sizes to achieve sufficient degassing.
Innovation Solution
A lubricating oil tank design featuring multiple receiving parts, such as oil trays, arranged vertically with overflow and oil receiving portions, and optionally including partition plates, to facilitate air bubble separation through gravity and flow management, ensuring efficient degassing while maintaining a compact tank size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the capacity of the lubricating oil tank is increased to lengthen the residence time for air bubble separation, then the air bubble removal efficiency is improved, but the size of the lubricating oil tank increases
Solution Approach 1:
The tank is divided into multiple receiving parts (first receiving part, second receiving part, etc.) arranged vertically. Each receiving part acts as an independent degassing zone, allowing the lubricating oil to be processed in stages. This segmentation enables effective air bubble removal without requiring a single large tank volume, as the oil passes through multiple smaller compartments in sequence.
Solution Approach 2:
The receiving parts are arranged in the vertical dimension rather than horizontally expanding the tank. By stacking multiple receiving parts vertically, the patent achieves extended residence time and multiple degassing stages without increasing the horizontal footprint of the tank, thus maintaining a compact overall size while improving air bubble removal efficiency.
2Object-generated harmful factors
If air bubble passage preventing means such as mesh-like filter members or baffle plates are provided, then air bubble passage is prevented, but it is difficult to remove air bubbles in a short time and with high accuracy
Solution Approach 1:
Instead of using a single large tank or simple baffle plates, the invention segments the tank into multiple receiving parts with delivery parts between them. This creates multiple sequential degassing stages, allowing air bubbles to be removed more efficiently and completely in a shorter overall time compared to single-stage systems or simple barrier methods.
Solution Approach 2:
The lubricating oil delivery part acts as an intermediary mechanism between receiving parts. It controls the flow of lubricating oil from one receiving part to the next, ensuring optimal residence time in each compartment while maintaining continuous operation. This intermediary flow control enables efficient degassing without requiring excessive time or complex filtering mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively removes air bubbles from lubricating oil in a short time with high accuracy, reducing the size of the lubricating oil tank while maintaining efficient degassing, thereby preventing lubrication performance impairment.
Implementation Method 1
the air bubbles sequentially escape from the liquid level of the lubricating oil in the stored state into the atmosphere by gravity (a difference in specific gravity between the lubricating oil and the air bubbles)
