Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The plunger pump in fracturing apparatuses experiences significant vibrations due to factors like flow of fracturing fluid and high-speed rotation, leading to displacement fluctuations, reduced service life, and potential equipment damage, which existing technologies fail to adequately address.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plunger pump operates at high speed to increase productivity, then the fracturing efficiency is improved, but the vibration intensity increases causing displacement fluctuations and reduced service life
Solution Approach 1:
The patent implements a feedback control system where vibration sensors continuously monitor the plunger pump's vibration intensity, and the control device receives this information to adjust operating parameters. The system dynamically adjusts the number of strokes based on real-time vibration data, creating a closed-loop feedback mechanism that prevents excessive vibration while maintaining high productivity.
Solution Approach 2:
The patent dynamically adjusts the operating parameters of the plunger pump based on real-time vibration conditions. The control device modifies the number of strokes dynamically rather than operating at fixed high speed, allowing the system to adapt its speed and load to minimize vibration intensity while maintaining overall productivity through intelligent parameter variation.
2Productivity
If the plunger pump operates continuously at high intensity, then the fracturing work efficiency is improved, but the displacement stability deteriorates due to vibration
Solution Approach 1:
The control device uses real-time feedback from vibration sensors to monitor displacement stability conditions. When vibration intensity exceeds thresholds that would compromise displacement stability, the system automatically adjusts the number of strokes to restore stability, maintaining continuous operation while preserving displacement control accuracy.
Solution Approach 2:
The system dynamically adjusts the number of strokes based on real-time vibration and displacement stability conditions. This dynamic parameter adjustment allows the plunger pump to maintain high work efficiency during stable operation while automatically reducing intensity when displacement stability is threatened, achieving both productivity and stability goals.
3Device complexity
If the plunger pump operates without vibration monitoring, then the device complexity is reduced, but the equipment damage risk increases due to uncontrolled vibration
Solution Approach 1:
The patent incorporates vibration monitoring sensors and a control device that receives feedback from these sensors. This feedback system continuously monitors vibration intensity and triggers automatic adjustments when thresholds are exceeded, providing real-time protection against equipment damage while adding only minimal system complexity through standardized sensing and control components.
Solution Approach 2:
The control device automatically monitors vibration conditions and adjusts the plunger pump's number of strokes without requiring external intervention. The system serves itself by detecting abnormal vibration conditions and autonomously implementing protective measures, reducing equipment damage risk while maintaining simple operation without manual monitoring requirements.
