Modular Pump Skid Assembly With Adjustable Check Valve Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable pump systems with internal combustion engines face challenges in accommodating different pump and engine sizes due to rigid skid assemblies that lack flexibility in mounting and adjustment, leading to issues with alignment, center of gravity, and limited adaptability, and lack of self-contained hazardous material provisions.
Innovation Solution
A modular skid assembly with an adjustable check valve support and removable fuel tank, allowing for flexible mounting of various pump and engine sizes, adjustable center of gravity, and dual containment of hazardous materials, convertible between drag skid and wheeled trailer configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid skid assemblies are used for mounting pumps and engines, then structural stability is maintained, but flexibility and adaptability for different pump and engine sizes are reduced
Solution Approach 1:
The skid assembly is divided into modular components including separate mounting plates, adjustable support structures, and detachable connections. This segmentation allows different pump and engine combinations to be mounted on the same skid by reconfiguring the modular elements rather than requiring a custom rigid structure for each configuration.
Solution Approach 2:
Adjustable support structures with movable components enable the skid assembly to dynamically adapt to different pump and engine sizes. The support positions and mounting heights can be modified as needed, providing flexibility while maintaining structural stability during operation.
2Ease of operation
If fixed mounting structures are used, then alignment precision is maintained, but ease of adjustment and reconfiguration is reduced
Solution Approach 1:
Alignment features and mounting interfaces are pre-configured with precision during manufacturing, including precision-machined surfaces and pre-positioned mounting holes. This preliminary precision work enables easy field adjustment and reconfiguration without compromising alignment accuracy, as the base alignment is already established.
Solution Approach 2:
Adjustable mounting plates and intermediate support structures serve as mediators between the fixed skid base and the pump/engine components. These intermediaries provide both the stability of fixed mounting and the flexibility of adjustment, allowing precise alignment to be achieved and maintained while enabling easy reconfiguration.
3Reliability
If integrated fuel tank design is used, then structural simplicity is maintained, but safety and hazardous material containment are reduced
Solution Approach 1:
The fuel tank is designed as a separate, removable component rather than being integrated into the skid structure. This segmentation allows the fuel tank to be easily removed for cleaning or replacement and provides dual containment capabilities, improving safety while maintaining relatively simple overall structure through standardized interfaces.
Solution Approach 2:
The fuel tank is extracted from the integrated skid design and made into a separate removable unit. This extraction improves safety by allowing the hazardous material containment to be independently managed, cleaned, and replaced without affecting the skid structure, while the connection interfaces keep the overall system relatively simple.

AI summary
A diesel driven pump package converts from a drag skid to a wheeled trailer. A skid assembly includes a welded base with a basin. A removeable fuel tank fits within the basin. Multiple mounting crosspieces extend over the fuel tank overlap side rails of the welded base and are bolted to the side rails via longitudinal slots. An engine bracket is mounted on a first one of the multiple mounting crosspieces to support an engine. A pump bracket is mounted on a second one of the multiple mounting crosspieces to supports a pump. A check valve support braces a check valve extending from the pump volute. The check valve support includes an adjustable arm. A trailer package removably attaches to the skid assembly to convert the skid assembly to a wheeled trailer.
