Vertical Electric Pump Single-Side Instrument Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vertical electric pumps have expansion tanks and control/monitoring instruments arranged in different locations, making maintenance difficult, time-consuming, and space-intensive.
Innovation Solution
The instruments for control and monitoring, including an expansion tank, are designed to be entirely accessible from a single side of the pump, reducing the need for user memory and space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expansion tank and control instruments are arranged in different locations and/or sides of the pump, then the pump can maintain its functional performance, but maintenance becomes difficult and time-consuming
Solution Approach 1:
The patent combines the expansion tank and control instruments into a single integrated assembly located on one side of the pump housing. This merging allows both components to be accessed simultaneously from the same location, resolving the contradiction by maintaining functional performance while significantly improving maintenance accessibility.
Solution Approach 2:
The integrated assembly serves multiple functions: it houses both the expansion tank for pressure regulation and the control instruments for monitoring and operation. This multi-functional design consolidates previously separate components into a single accessible location, improving ease of repair without compromising reliability.
2Ease of manufacture
If expansion tank and control instruments are arranged in different locations, then the pump design follows traditional layout conventions, but space occupation increases and user accessibility decreases
Solution Approach 1:
By merging the expansion tank and control instruments into a single integrated assembly, the patent reduces the total space occupied in the pump housing. This consolidation eliminates the need for separate locations for each component, thereby reducing overall space occupation while maintaining ease of manufacture through standardized assembly design.
3Reliability
If expansion tank and control instruments are arranged in different locations, then the pump can maintain its operational functionality, but maintenance time increases and operation interruption time increases
Solution Approach 1:
The integrated assembly is pre-configured during manufacturing with all necessary connections and mounting arrangements. This preliminary action ensures that during maintenance, technicians can access and service both the expansion tank and control instruments simultaneously without needing to locate and connect separate components, thereby reducing maintenance time while maintaining operational functionality.
