Plunger Pump Anti-Loosening Bracket for Packing Nut Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In hydraulic fracturing operations, the continuous reciprocating motion of plungers in plunger pumps often causes fasteners like packing nuts to loosen due to vibration, leading to frequent inspections and potential equipment damage, affecting efficiency and safety.
Innovation Solution
An anti-loosening device comprising a first and second bracket with an elastic member, which abuts against stay rods and a fastener to prevent rotation, ensuring the fastener remains securely locked without requiring additional tools for installation or removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fasteners are used without anti-loosening mechanism, then the device structure is simple and easy to install, but the fasteners loosen due to vibration during reciprocating motion
Solution Approach 1:
The anti-loosening device is divided into two separate brackets (first bracket and second bracket) that can be independently installed on opposite sides of the fastener, with each bracket having its own clamping part and connecting part, allowing modular assembly and disassembly without affecting the entire system
Solution Approach 2:
The elastic member acts as an intermediary between the first and second brackets, providing elastic force that pushes the brackets apart to clamp the fastener, enabling the anti-loosening function without direct mechanical connection between the brackets and the fastener
2Reliability
If additional anti-loosening components are added, then fastener loosening is prevented, but installation and removal require additional tools and time
Solution Approach 1:
The elastic member provides self-generating elastic force that automatically clamps the fastener when the brackets are positioned, eliminating the need for additional locking mechanisms or tools during installation and removal
Solution Approach 2:
The elastic member provides dynamic adaptability, allowing the brackets to be easily positioned and locked onto the fastener through the elastic force, facilitating tool-free installation and removal while maintaining reliable clamping
3Stability of the object's composition
If rigid connection between brackets is used, then structural stability is high, but the device cannot adapt to relative movement during operation
Solution Approach 1:
The elastic member transforms the rigid connection into a dynamic connection that can adapt to relative movements between the brackets during operation, maintaining stable clamping force while allowing necessary positional adjustments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-loosening device effectively prevents fastener loosening, reducing the frequency of on-site inspections, enhancing operational efficiency and safety by maintaining the secure locking of fasteners during plunger pump operations.
Implementation Method 1
The elastic member connects the first bracket and the second bracket, and is configured to control a relative movement of the first bracket and the second bracket in the first direction

AI summary
Embodiments of the present disclosure provides an anti-loosening device and a plunger pump. The anti-loosening device includes a first bracket, a second bracket and an elastic member. The first bracket includes a first clamping part defining a first accommodating space; a first connecting part extending in a first direction and fixedly connected to the first clamping part; and a limiting part fixedly connected to the first clamping part via the first connecting part, wherein the limiting part protrudes from the first connecting part in a second direction perpendicular to the first direction. The second bracket includes a second clamping part defining a second accommodation space, wherein the second clamping part is opposite to the first clamping part in the first direction; and a second connecting part extending in the first direction and fixedly connected to the second clamping part.
