Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-pressure pumps used in cryogenic applications face thermal distortion and stress challenges due to large temperature differences, particularly affecting bolted joints, which can lead to failure, and existing designs do not adequately address these issues.
Innovation Solution
The pump design incorporates a barrel with multiple bores, central, and peripheral passages, along with stability features and rims to create axial spaces for fluid communication, allowing for effective heat dissipation and thermal management, thereby reducing thermal distortion and stress on bolted joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional high-pressure pumps are used in cryogenic applications, then the pump can operate at high pressure, but thermal distortion and stress challenges occur due to large temperature differences affecting bolted joints
Solution Approach 1:
The patent applies local quality by providing thermal insulation specifically to the barrel and bolted joints, rather than insulating the entire pump. The insulation is applied selectively to components experiencing thermal stress, allowing the rest of the pump to maintain its design temperature gradient for efficient cryogenic operation.
Solution Approach 2:
The patent implements beforehand cushioning by pre-insulating the barrel and bolted joints against thermal exposure before operation begins. This protective measure prevents thermal distortion and stress from developing in the first place, rather than attempting to correct these issues after they occur.
2Reliability
If thermal insulation is applied to the barrel and bolted joints, then thermal distortion and stress are reduced, but the complexity of the pump design increases
Solution Approach 1:
The patent reduces complexity by applying insulation only where thermally critical - specifically the barrel and bolted joints - rather than insulating the entire pump assembly. This localized approach maintains reliability while minimizing the added complexity of the insulation system.
