Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for degassing and dehydrating hydraulic oil often produce noise due to vibrations caused by cavitation and supercavitation, and they are not efficient or cost-effective in maintaining a low air content and water level in hydraulic units.
Innovation Solution
A device with a flow lance decoupled from the tank using a vibration-decoupling module, combined with a casing to direct air bubbles back into the fluid surface and sensors to regulate air and water content, allowing for efficient degassing and dehydrating with reduced noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flow lance with restriction site is used to create cavitation zone for degassing, then air separation efficiency is improved, but noise level increases due to vibrations
Solution Approach 1:
A vibration decoupling module is introduced as an intermediary between the flow lance and the tank. This module includes a vibration decoupling element that absorbs and isolates vibrations generated by cavitation, preventing them from being transmitted to the tank walls and reducing noise while maintaining the degassing function
Solution Approach 2:
The vibration source (flow lance) is extracted from direct contact with the tank structure. By removing the rigid connection between the flow lance and tank, the harmful vibrations are isolated and cannot propagate to the tank walls, thereby reducing noise transmission
2Stability of the object's composition
If flow lance is rigidly connected to tank, then structural stability is improved, but noise transmission increases
Solution Approach 1:
The vibration decoupling element acts as a flexible connection between the flow lance and tank. This flexible element provides mechanical support and stability while allowing vibration isolation, effectively decoupling the rigid structural connection that would transmit noise

AI summary
A device for degassing and/or dehydrating a hydraulic oil includes a flow lance, a flow duct, and a decoupling module. The flow lance includes a restriction site via which the hydraulic oil flows under a high pressure drop. The flow duct is configured as a pipe that is located downstream of the restriction site. The quantity of oil that flows via the restriction site and a throughflow cross section of the restriction site are coordinated to one another such that a cavitation zone or supercavitation zone forms downstream of the restriction site. The flow duct has a significantly larger cross section with respect to the throughflow cross section of the restriction site. For a quiet operation of the device, the flow lance is held in the decoupling module via which the flow lance is configured to be fastened in a vibration-decoupled manner to a tank.
