Reciprocating Pump Mount Plate Spaced Coupling Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pressure reciprocating pumps face challenges in securely and stably coupling the fluid end to the power end, limiting compatibility with different fluid ends and requiring frequent disassembly for maintenance, which increases downtime and reduces operational efficiency.
Innovation Solution
A mount plate is introduced that provides a spaced relationship between the power end and fluid end, allowing for flexible coupling using various couplers and pony rods, enabling access to the reciprocation bore for servicing without full disconnection, and accommodating different fluid end geometries with a single power end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the fluid end is directly coupled to the power end, then structural stability is maintained, but access to the reciprocation bore for maintenance is limited and requires full disassembly
Solution Approach 1:
The coupling structure is segmented into a mount plate and separate couplers. The mount plate is attached to the power end, while couplers connect the mount plate to the fluid end. This segmentation allows the reciprocation bore to be accessed by removing only the couplers and mount plate, without disassembling the entire pump, thereby improving maintenance access while maintaining structural stability through the rigid mount plate connection.
2Adaptability or versatility
If traditional mounting points are used on the power end, then structural integrity is maintained, but compatibility with different fluid end geometries is limited
Solution Approach 1:
The mount plate serves as a universal interface between the power end and various fluid end geometries. By providing multiple opening patterns on the mount plate, a single power end can accommodate different fluid end designs. The couplers act as flexible connectors that adapt to different mounting configurations, enabling one power end to work with multiple fluid end types while maintaining structural integrity through the rigid mount plate.
3Productivity
If the fluid end is securely coupled to the power end, then operational stability is maintained, but downtime for maintenance increases due to frequent disassembly
Solution Approach 1:
The coupling system is divided into modular components (mount plate and couplers) that can be independently removed. This allows quick disassembly and reassembly of the fluid end from the power end without affecting the entire pump system. The mount plate remains attached to the power end, providing a stable base that simplifies maintenance operations and reduces downtime by enabling rapid replacement of worn components.
4Ease of repair
If a spaced relationship is created between power end and fluid end, then access for servicing is enabled, but structural stability under high stress may be compromised
Solution Approach 1:
The mount plate is pre-attached to the power end with multiple openings positioned to receive couplers. This preliminary configuration ensures that when couplers are installed, they automatically create the proper spaced relationship between the power end and fluid end. The multiple openings allow for redundant coupler placements that distribute structural loads, maintaining coupling stability under high stress while preserving service access through the created space.

AI summary
A mount plate for removably connecting a fluid end of a reciprocating pump to a power end for a reciprocating pump includes a first set of openings and a second set of openings, each of which extend through the main body. The first set of openings are configured to receive a first set of couplers that couple the mount plate to a front of the power end. The second set of openings are configured to receive a second set of couplers that couple the mount plate to a fluid end in a spaced relationship. The mount plate may also include a third set of openings that extend through the main body and are configured to receive pony rods of the power end.
