Circulation Bypass Arrangement for Hydraulic System Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circulation bypass arrangements connected to hydraulic systems, such as automatic fire sprinkler systems, require significant effort to disassemble for maintenance, wear part replacement, or exchange, often leading to leakage issues due to misalignment.
Innovation Solution
The circulation bypass arrangement features a connecting part and a circulation pump unit connected via a union nut, with the connecting part secured to the first connection arrangement using a lock nut. This configuration allows for easy disassembly by creating an axial distance, enabling the removal and exchange of wear parts without disturbing the connection to the hydraulic system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the circulation bypass arrangement is connected to the hydraulic system using multiple screw connections, then the connection reliability is improved, but the disassembly effort and complexity increase significantly
Solution Approach 1:
The circulation bypass arrangement is divided into separable components (circulation pump unit, connecting part, wear part) that can be disassembled independently. The connecting part acts as a intermediate segment that can be removed without affecting the main connection to the hydraulic system, enabling easy maintenance while preserving connection reliability through the use of union nuts and lock nuts.
2Ease of operation
If the circulation bypass arrangement is designed for easy disassembly, then the maintenance effort is reduced, but the risk of leakage and tightness problems increases
Solution Approach 1:
The connecting part serves as an intermediary component between the circulation pump unit and the first connection arrangement. It houses the wear part and provides interfaces for both the union nut (connecting to pump unit) and lock nut (connecting to first connection arrangement). This intermediary structure enables easy disassembly for maintenance while maintaining tightness reliability through proper sealing interfaces at each connection point.
3Stability of the object's composition
If the connecting part is securely fastened to the hydraulic system, then the system stability is improved, but the ability to access and replace wear parts decreases
Solution Approach 1:
The system is segmented into a permanently connected first connection arrangement and a removable circulation pump unit assembly. The connecting part with the wear part is designed as a separate module that can be accessed by removing only the union nut and lock nut, without needing to disconnect the first connection arrangement from the hydraulic system. This segmentation maintains system stability while improving wear part accessibility.
4Strength
If multiple screw connections are used to secure the circulation bypass arrangement, then the connection strength is improved, but the number of components and assembly complexity increase
Solution Approach 1:
The connection complexity is extracted and concentrated into two specific locations: the union nut connection between the connecting part and circulation pump unit, and the lock nut connection between the connecting part and the first connection arrangement. By extracting the fastening requirements to these two key points rather than using multiple screw connections throughout, the design maintains connection strength while reducing overall assembly complexity.
