Modular Pump Skid Layout for Alignment and Check Valve Bracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skid assemblies for portable pump systems are typically fully-welded and require customization for each pump/motor combination, leading to inefficiencies in alignment, structural rigidity, and center of gravity issues, making them inflexible and costly for various equipment sizes and configurations.
Innovation Solution
A modular skid frame with bolt-on supports for motors, pumps, and adjustable components such as check valve supports, allowing for customizable alignment and rigidity while accommodating different sizes and orientations of pumps and motors, using a single base design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fully-welded custom skids are used for each pump/motor combination, then structural rigidity and alignment precision are improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The skid is divided into modular components including standardized base frames and interchangeable support structures. Each support structure can be independently selected and assembled to accommodate different pump and motor configurations, eliminating the need for fully custom welded skids for each combination.
Solution Approach 2:
A single standardized base frame design serves multiple functions by accommodating various pump and motor sizes through interchangeable support structures. This universal base frame can be configured for different equipment arrangements, reducing the need for multiple custom-skid designs.
2Strength
If fully-welded custom skids are manufactured for each configuration, then structural rigidity is improved, but ease of manufacture and production efficiency deteriorate
Solution Approach 1:
The skid system is segmented into a standardized base frame and separate interchangeable support structures. These components can be manufactured independently using standardized processes, then assembled through bolting rather than welding, significantly improving manufacturing efficiency while maintaining structural rigidity through proper component design.
Solution Approach 2:
The interchangeable support structures are designed as standardized, easily replaceable components that can be manufactured cost-effectively. If a support structure becomes damaged or needs reconfiguration, it can be replaced by bolting on a new one rather than requiring complex welding operations, reducing manufacturing costs and time.
3Adaptability or versatility
If standardized base frames with bolt-on supports are used, then ease of manufacture and adaptability are improved, but structural rigidity may deteriorate compared to fully-welded constructions
Solution Approach 1:
The support structures are pre-designed and pre-drilled with bolt holes in standardized patterns. This preliminary preparation allows for quick assembly while ensuring proper structural alignment and rigidity. The pre-engineered connection points are positioned to optimize structural strength while maintaining adaptability.
Solution Approach 2:
The support structures incorporate adjustable parameters such as adjustable leg lengths and reconfigurable bolt patterns. These parameter changes allow the same standardized support structure to adapt to different pump and motor configurations while maintaining structural rigidity through optimized geometric design and material selection.

AI summary
A modular skid assembly is provided for a pump driven by an electric motor. The skid assembly has a base including slats. A motor support to position the motor is configured to rest on the slats and to be bolted to the slats. A frame support to position a pump bearing frame is configured to rest on the slats and to be bolted to the slats. A volute support to support a pump volute is configured to rest on the slats and to be bolted to the slats. A lifting bail is configured to be bolted to the slats in one of multiple longitudinal positions along the base. A check valve support is configured to brace a check valve extending from the pump volute. The check valve support includes an adjustable arm that extends to put the adjustable arm in compression between the check valve and the base.
