Centrifugal Pump Rotatable Housing for Flexible Outlet Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing centrifugal pumps require multiple component changes to adjust the arrangement of suction and pressure outlets, increasing manufacturing, storage, and inventory complexities due to fixed component configurations.
Innovation Solution
A multi-part housing design with an intermediate housing part and a second housing part that can be arranged in various positions relative to the first and third housing parts, allowing for flexible positioning of the pressure connection without altering components, including rotational and axial adjustments, enabling the same components to be used for different configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suction inlet and pressure outlet are arranged on the same axis in the foot of the pump, then the construction is simple and robust, but the arrangement of connection variants is limited and requires component changes
Solution Approach 1:
The second housing part is made rotatable about the longitudinal axis, allowing dynamic repositioning of the pressure connection to different angles without changing the physical components. This converts a static component arrangement into a dynamically adjustable one, resolving the contradiction between adaptability and component variety.
Solution Approach 2:
The solution adds rotational freedom in the angular dimension, allowing the pressure connection to be positioned at different angles around the longitudinal axis. This dimensional freedom enables multiple connection variants using the same components, eliminating the need for multiple housing part designs.
2Adaptability or versatility
If different connection variants are constructed with different component arrangements, then the pressure outlet can be positioned flexibly, but the manufacturing, storage, and stocking complexity increases
Solution Approach 1:
The second housing part serves multiple functions: it contains the pressure connection, provides structural support, and enables angular adjustment through rotation. This multi-functionality allows a single universal component design to replace multiple specialized housing parts, simplifying manufacturing and inventory management.
Solution Approach 2:
By making the second housing part rotatable, the same physical component can be oriented in multiple positions to create different connection variants. This dynamic capability eliminates the need to manufacture, store, and manage multiple different housing part designs for different connection configurations.
3Adaptability or versatility
If the pressure connection position is fixed relative to the pump stages, then the component design is simplified, but the installation adaptability to different situations is reduced
Solution Approach 1:
The rotatable second housing part allows the pressure connection to be dynamically repositioned angularly around the longitudinal axis. This creates installation adaptability to different spatial configurations without requiring complex multi-variant housing part designs, as the same housing part can be rotated to match different installation requirements.
