Evaluation Device for Emergency System Testing in Fluid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel transfer systems face challenges in preventing tank overflows due to delayed reaction times of emergency systems, which can lead to environmental and economic hazards, especially when the flow rate of fuel is high.
Innovation Solution
An evaluation device that connects to both the metering system and the emergency system, allowing for precise measurement of fluid transferred during emergency valve closure, enabling assessment of whether the emergency system can prevent overflows by modifying and sending control signals to the emergency system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency system reacts quickly to close the emergency valve, then overflow prevention is improved, but measurement precision of fluid transferred during closure deteriorates
Solution Approach 1:
The evaluation device is pre-configured with signal ports connected to both the metering device and emergency system. The evaluation unit is ready to receive control signals and modify them before sending back, enabling precise measurement setup before the actual emergency closure event occurs.
Solution Approach 2:
The evaluation device acts as an intermediary between the metering device and emergency system. It receives the control signal from the emergency system, modifies it, and sends it back, while simultaneously measuring the fluid transfer through its connection to the metering device. This intermediary role allows precise measurement without interfering with the emergency response function.
2Measurement precision
If the reaction period of the emergency system is extended for evaluation, then measurement precision improves, but overflow prevention capability deteriorates
Solution Approach 1:
The evaluation device creates a copy of the control signal path by receiving the control signal from the emergency system, modifying it, and sending it back through the same or a parallel path. This copying mechanism allows the system to evaluate the response time and fluid transfer measurement simultaneously without extending the actual reaction period needed for overflow prevention.
3Reliability
If the emergency valve closes within a very short time interval, then overflow prevention is improved, but the ability to measure and evaluate fluid transfer deteriorates
Solution Approach 1:
The evaluation device performs multiple functions simultaneously: it measures the control signal from the emergency system, modifies the control signal for evaluation purposes, sends the modified signal back to the emergency system, and measures the fluid transfer through its connection to the metering device. This multi-functionality allows comprehensive evaluation without adding separate complex measurement systems.
