Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubrication nozzles face challenges in accurately directing lubricant streams and minimizing lubricant loss during reduced or low airflow conditions, leading to inefficient lubrication and increased operational costs due to excessive lubricant coagulation and run-off.
Innovation Solution
A nozzle with a tubular housing and tapered passageways in the emitter head converts a sheet-like lubricant flow into consistently sized drops, utilizing a carrier gas to propel them to the target, minimizing dripping and lubricant loss by efficient collection and separation of lubricant and gas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If air pressure is lowered to reduce operational costs, then energy costs are reduced, but insufficient extraction of lubricant from the aerosol occurs leading to excessive lubricant loss
Solution Approach 1:
The emitter head geometry parameters (taper angle, passage dimensions) are optimized to maintain effective lubricant extraction and atomization across a wide range of air pressures, allowing the system to operate efficiently at lower pressures without sacrificing lubricant delivery performance
Solution Approach 2:
The nozzle design dynamically adapts to varying air pressure conditions through its tapered passageway geometry, which maintains stable lubricant flow and drop formation across different operating pressures, enabling flexible operation from continuous to cyclic modes
2Loss of energy
If cycling systems are used to conserve air, then air costs are reduced, but lubricant accumulation and run-off occur through the nozzle when airflow is off or below threshold pressure
Solution Approach 1:
The tapered emitter head geometry creates a self-draining effect that prevents lubricant accumulation during off-periods by directing any accumulated lubricant back toward the inlet, counteracting the potential for run-off before it can occur
Solution Approach 2:
The specific taper angle and passage dimensions of the emitter head are designed to maintain stable lubricant flow characteristics across the full range of operating conditions, preventing accumulation and run-off during cyclic operation
3Quantity of substance
If a mist system is used to provide lubrication, then lubricant can be dispersed, but the lubricant coagulates into drops of various sizes impeding control over the amount dispersed
Solution Approach 1:
The tapered passageway geometry parameters (taper angle, entrance width, exit dimensions) are specifically optimized to control lubricant flow and atomization, producing consistently sized drops across a wide range of operating conditions
Solution Approach 2:
The emitter head design segments the lubricant flow into uniformly sized drops through its tapered geometry, creating consistent atomization patterns that improve control over lubricant delivery quantity and distribution
4Reliability
If compressed air is provided to a plurality of nozzles, then lubrication coverage is improved, but operational costs increase due to energy consumption
Solution Approach 1:
The emitter head geometry is optimized to maximize lubricant extraction efficiency at reduced air pressures, allowing multiple nozzles to be operated at lower pressures while maintaining adequate lubrication coverage
Solution Approach 2:
The system allows flexible operation between continuous and cyclic airflow modes, enabling optimization of air consumption based on specific application requirements while maintaining reliable lubrication performance

Function Achieved in This Case
The solution ensures precise and efficient lubricant delivery with reduced lubricant loss and operational costs by maintaining consistent drop size and minimizing dripping, even under low airflow conditions, while being economical and compatible with existing lubrication systems.
Implementation Method 1
The passageways are of a tapered configuration, having a wide width entrance area to effect efficient collection of the lubricant and carrier gas, and an exitway of narrowed size, allowing the lubricant to be delivered to a needle-like end at the head where the drops are formed
Implementation Method 2
a series of lubricant drops that are directed to a lubricant target by an accompanying carrier gas flow

AI summary
A nozzle for a mist lubricator system has an emitter head located in a tubular housing. The emitter head has tapered passageways terminating at an end from which lubricant drops are directed to a target to be lubricated. The emitter head can be incorporated in lubricator systems of various types, including those utilizing a cycling feed metering system. A nozzle constructed in accordance with the present invention can be used in reduced airflow systems and exhibits substantially lessened lubricant loss during low and no airflow periods.
