Reciprocating Pump Mount Plate for Serviceable Fluid-End Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 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 extensive disassembly for maintenance, which leads to increased downtime.
Innovation Solution
A mount plate is used to couple the fluid end to the power end, providing spaced relationships and multiple sets of couplers to allow access to the reciprocation bore for servicing without full disconnection, enhancing compatibility and reducing maintenance downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the fluid end is directly coupled to the power end, then the coupling is secure and stable, but access to reciprocation bore for servicing requires complete disassembly
Solution Approach 1:
The coupling structure is divided into three separate components: a mount plate attached to the power end, and two couplers (first and second couplers) that connect the mount plate to the fluid end. This segmentation allows the reciprocation bore to be accessed by removing only the couplers while the mount plate remains attached to the power end, enabling partial disassembly for servicing.
2Adaptability or versatility
If traditional mounting points are used on the power end, then the mounting is straightforward, but compatibility with different fluid ends is limited
Solution Approach 1:
The mount plate serves as an intermediary component between the power end and the fluid end. It provides standardized mounting points on the power end and corresponding coupling interfaces for different fluid ends, enabling a single power end to accommodate multiple fluid end types through the universal mount plate design.
3Ease of repair
If the fluid end is completely disconnected for servicing, then full access is achieved, but downtime increases
Solution Approach 1:
The coupling system is segmented into the mount plate (remaining on power end) and removable couplers (connecting to fluid end). This allows servicing to be performed by removing only the couplers while the mount plate stays attached to the power end, enabling partial disassembly that reduces maintenance downtime compared to complete disconnection.

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.
