Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fracturing apparatuses in oil and gas exploitation face challenges with clutch slip phenomena due to low hydraulic pressure, leading to potential faults and increased maintenance costs.
Innovation Solution
A fracturing apparatus equipped with a clutch hydraulic system and pressure sensors that detect hydraulic pressure, allowing for clutch disengagement when pressure falls below a preset value, thereby preventing slip and potential faults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the clutch hydraulic system operates at low pressure, then energy consumption is reduced, but clutch slip occurs leading to faulty engagement and disengagement
Solution Approach 1:
The control system performs preliminary detection of hydraulic pressure before clutch engagement. When pressure is detected to be below the threshold, the control system preemptively prevents clutch engagement or triggers an alarm, avoiding the harmful slip phenomenon before it occurs. This preliminary action ensures reliable engagement only when hydraulic pressure is sufficient.
2Reliability
If pressure detection and control systems are added, then clutch slip is prevented, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where pressure sensors continuously monitor hydraulic pressure and feed this information to the control system. The control system compares the detected pressure with the preset threshold and automatically adjusts clutch engagement status or triggers alarms. This closed-loop feedback ensures reliable clutch operation while automating the control process.
Solution Approach 2:
The patent replaces complex mechanical pressure indication systems with electronic pressure sensors and digital control systems. The electronic detection and control mechanisms provide more precise pressure monitoring and automated decision-making, reducing the need for complex mechanical linkages and manual monitoring while improving reliability.
