Cavitation Detection via Engine Torque and Fuel Fluctuations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for detecting pump cavitation rely heavily on vibration sensors, which are not always effective, and there is a need for a more reliable and sensor-independent approach to monitor engine torque load and instantaneous fuel consumption for early detection of cavitation.
Innovation Solution
A machine-learning controller configured to monitor engine torque load and instantaneous fuel consumption for significant drops or erratic fluctuations, allowing for the detection of pump cavitation without additional sensors by establishing acceptable ranges through machine learning processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration sensors are used to detect pump cavitation, then cavitation detection capability is provided, but device complexity increases and reliability is compromised due to sensor limitations
Solution Approach 1:
The patent extracts the cavitation detection capability from the pump system by monitoring engine parameters (torque load and fuel consumption) separately, rather than requiring sensors directly on the pump. This removes the need for vibration sensors while maintaining detection capability through indirect measurement of cavitation effects on engine performance
Solution Approach 2:
The patent introduces engine torque load and fuel consumption as intermediary parameters that mediate between the pump cavitation state and the detection system. These engine parameters serve as proxies that reflect pump cavitation conditions without requiring direct sensing of the pump itself, thereby simplifying the overall system architecture
2Measurement precision
If additional sensors are installed for cavitation detection, then measurement precision improves, but device complexity and cost increase
Solution Approach 1:
The patent enables the engine's existing control system to serve the dual purpose of its primary function and cavitation detection. The engine control unit, which already monitors torque and fuel consumption for operational control, now also provides cavitation detection capabilities, eliminating the need for separate sensing systems while maintaining detection precision
Solution Approach 2:
The patent makes the engine control system universal by赋予 it multiple functions: both engine operation control and pump cavitation detection. This multi-functionality allows existing sensors and processing units to serve dual purposes, reducing overall system complexity while maintaining measurement precision through the same hardware infrastructure

AI summary
Exemplary embodiments are disclosed of controllers (e.g., control panels, etc.) configured to be operable for detecting cavitation using torque load and/or instantaneous fuel consumption. In exemplary embodiments, a controller is configured to be operable for monitoring at least one of engine torque load and/or engine instantaneous fuel consumption for fluctuation (e.g., significant drop/downward fluctuation in average magnitude and/or erratic, noisy, fluctuating data, etc.) indicative of pump cavitation, thereby enabling the controller to be operable for alerting to indications of pump cavitation when fluctuation of the monitored engine torque load and/or engine instantaneous fuel consumption indicate pump cavitation.
