Centrifugal Pump Mounting Collar for Any-Angle Motor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing centrifugal pumps require complete detachment from piping for realignment due to fixed, 90° spaced screw fastening, limiting installation flexibility and compatibility with complex piping configurations.
Innovation Solution
A centrifugal pump design allowing the motor housing to be fixed in any rotational position using a ring-shaped mounting collar and spaced-apart fastening means, enabling rotation without disconnecting from the pipe system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If four screws spaced 90° apart are used to fasten the motor housing to the pump housing, then the motor housing can be securely fixed, but only four defined orientations are possible and rotation is not possible without draining the pipe system
Solution Approach 1:
The fastening system is segmented into multiple individual fastening means (at least two, preferably three or four) distributed around the circumference of the mounting collar. Each fastening means can independently secure the motor housing at different angular positions, allowing the system to provide both secure fixation and rotational flexibility. The mounting collar itself is segmented with multiple attachment points around its circumference.
Solution Approach 2:
The fastening means are designed to be releasable, transforming the static fixed connection into a dynamic one. During installation, the fastening means can be engaged or disengaged to allow the motor housing to be rotated to any desired orientation. Once positioned, the fastening means secure the motor housing in that specific rotational position, enabling adaptation to different piping configurations without requiring complete detachment.
2Device complexity
If the motor housing is fixed in predefined orientations, then the fastening structure is simple, but installation in confined spaces with existing piping is difficult
Solution Approach 1:
The mounting collar with distributed fastening means serves multiple functions: it provides secure mechanical attachment, enables rotational adjustment to any orientation, and adapts to various piping configurations. This universal design allows the same fastening structure to accommodate different installation scenarios without requiring complex specialized mechanisms for each case.
Solution Approach 2:
The fastening means are designed to be engaged after the motor housing is positioned in the desired rotational orientation, rather than constraining the orientation beforehand. This preliminary positioning followed by securing allows installers to first align the motor housing with existing piping in confined spaces, then engage the fastening means to lock it in place, simplifying installation in difficult-to-reach areas.
