Immersible Machine Partition Sealing and Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing partitions in immersible machines fail to provide reliable fluid-tight sealing between the motor and coupling compartments, leading to potential liquid leakage and loose electrical connections, especially when the machines are tilted or shaken, and require skilled operator intervention for secure coupling.
Innovation Solution
A partition with a sealing member and retention means, featuring primary and secondary spring clips accessible from both sides, ensuring secure retention and fluid-tight sealing without complex devices, using a sealing member like an O-ring between the partition wall and coupling terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the machine is tilted or shaken, then process liquid may leak from coupling compartment to motor compartment, but using a tower with overflow function increases the risk of leakage before allowed level is reached
Solution Approach 1:
The partition wall acts as an intermediary barrier between the coupling compartment and motor compartment. By providing a robust sealing structure with embedded coupling terminals that maintain fluid tight sealing, the partition prevents liquid leakage during tilting or shaking operations without requiring an overflow tower that could compromise containment reliability.
2Ease of operation
If screw retentions are used for coupling terminals, then electrical conductors can be connected, but faultless coupling is exclusively dependent on the skills of the operator and may shake loose
Solution Approach 1:
The spring clips provide self-retaining functionality where the elastic force of the springs automatically secures the electrical conductor without requiring precise manual adjustment. The primary and secondary spring clips work together to self-adjust and maintain secure engagement, eliminating dependence on operator skill while ensuring reliable connection during operation.
