Twin Pump Casing Stability via Segmented Leg Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump casings in twin pump configurations face challenges in stability, noise, and vibration due to the integrated nature of the pump casings and shared suction and discharge ports, which complicates installation and operation.
Innovation Solution
The introduction of leg portions in the suction branching and discharge merging portions of the pump casing, along with screw holes and base parts, enhances stability and reduces noise and vibration by providing additional structural support and attachment points.

Engineering Contradiction Analysis
1Area of stationary object
If pump casings for two pumps are integrally manufactured in a twin pump configuration, then space is saved and pump lifetime is extended through alternating operation, but stability and noise suppression are deteriorated due to complex integrated structure
Solution Approach 1:
The pump casing is divided into separate first and second pump casings instead of being integrally manufactured. Each pump casing is independently structured with its own leg portions, allowing for better stability while maintaining the space-saving benefits of the twin pump configuration. The segmentation enables independent adjustment and installation of each pump unit.
2Ease of manufacture
If pump casings for two pumps are integrally manufactured, then manufacturing complexity is reduced, but installation accuracy and horizontality are deteriorated
Solution Approach 1:
By separating the pump casings into independent first and second pump casings, each casing can be manufactured and adjusted separately to ensure high installation accuracy. The leg portions are provided on each individual casing rather than on a shared integrated structure, enabling precise adjustment of each pump's horizontality and position during installation.
3Stability of the object's composition
If leg portions are added to suction branching and discharge merging portions, then stability is improved, but device complexity increases
Solution Approach 1:
The leg portions are integrated into the existing suction branching and discharge merging portions of the pump casings, combining the support function with the existing structural elements. This merging approach provides enhanced stability without adding completely separate components, thereby minimizing the increase in device complexity while achieving the desired stability improvement.
