Compressed Air Lubricator Atomizer Unit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressed air lubricators fail to provide a constant quantity of oil over a wide range of air flow rates and have limitations in transporting small to moderate oil quantities effectively, leading to pulsating oil delivery and inefficiencies in oil mist distribution.
Innovation Solution
An atomiser unit with air and oil supply nozzles is positioned at the base of the oil container, connected via a tube to the constriction in the flow channel, utilizing a Venturi valve and baffle plate to ensure continuous oil movement and a droplet separator for efficient oil mist transport, preventing backflow and allowing for adjustable oil mist delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an atomiser unit is supplied with compressed air from before the constriction and oil from the container base, then continuous oil movement into the main air flow is guaranteed, but the device complexity increases due to additional tubes and connections
Solution Approach 1:
A tube acts as an intermediary carrier to transport compressed air from before the constriction to the atomiser unit, enabling continuous oil supply without direct connection at the constriction point. This mediator allows the system to maintain reliability while managing complexity through functional decomposition.
Solution Approach 2:
The lubricator is segmented into distinct functional zones: the atomiser unit at the container base for oil pickup, the tube system for air delivery, and the constriction zone for mixing. This segmentation allows each component to perform its specific function reliably while the overall system complexity is managed through modular design.
2Manufacturing precision
If a droplet separator is arranged in the pipe for oil mist, then very fine oil mist transportable over great distance is guaranteed, but the device complexity increases
Solution Approach 1:
The droplet separator utilizes a porous structure with defined opening sizes to filter and refine the oil mist. This porous material approach achieves very fine oil mist quality suitable for long-distance transport while maintaining a relatively simple cylindrical component design that integrates into the existing pipe structure.
3Reliability
If ring nozzles with laterally freely moving pintles are used for oil supply holes, then protection against back flow is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The pintle is designed to move freely laterally within the ring nozzle, creating a dynamic sealing mechanism. During normal operation, the pintle position prevents backflow, while the mobility allows it to adapt to pressure variations. This dynamic design achieves reliable backflow protection through functional movement rather than complex fixed structures.
4Productivity
If the pipe for oil mist opens directly behind the baffle plate, then efficient oil mist introduction into main air flow is achieved, but the risk of excessive oil conveyance during venting increases
Solution Approach 1:
The system uses the natural feedback mechanism where compressed air flow rate regulates oil conveyance. During normal operation, the air flow through the atomiser unit controls oil pickup. During venting conditions, the reversed or reduced air flow automatically reduces oil conveyance, providing self-regulating control without additional feedback components.

This solution ensures a constant and reliable delivery of very fine oil mist over a large distance, effectively addressing the limitations of existing technologies by providing continuous oil supply without external adjustments, ensuring efficient oil transport and preventing excessive oil conveyance during normal operation.
Implementation Method 1
an atomiser unit which is supplied with air via a tube exiting from the flow channel before its constriction... this constriction is designed as a Venturi valve
Implementation Method 2
the pressure difference in accordance with the injector principle for transporting the oil is brought about by the air flowing past the atomiser nozzle at high speed
