Selectable-Diameter Intensifier Pump for Adjustable Pressure Ratios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intensifier pumps require multiple units with different pressure ratios to adjust output pressure, leading to increased equipment and personnel costs, and changing input fluid pressure can be impractical, especially when other devices are coupled to the same fluid line.
Innovation Solution
The intensifier pump design includes multiple adjustable piston and plunger diameters, allowing operators to change the intensity on the fly without altering the input pressure, by selecting from various piston and plunger configurations using an input port that locks into different diameters, enabling adjustable pressure ratios without replacing the pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple intensifier pumps with different pressure ratios are kept on site to adjust output pressure, then output pressure adaptability is improved, but equipment costs and personnel costs increase
Solution Approach 1:
The intensifier pump is designed with a universal structure that can perform multiple pressure ratio functions through interchangeable pistons with different diameters. Instead of requiring separate pumps for different pressure ratios, a single pump body can accommodate various pistons to achieve different output pressures, thereby reducing equipment costs while maintaining adaptability.
Solution Approach 2:
The pump system is segmented into interchangeable components, specifically pistons with different diameters that can be swapped out. This segmentation allows the main pump body to remain while only the piston component needs to be changed to adjust pressure ratio, reducing both equipment costs and the complexity of managing multiple complete pump systems.
2Adaptability or versatility
If intensifier pump replacement is performed to change pressure ratio, then output pressure adaptability is improved, but time required and personnel costs increase
Solution Approach 1:
By segmenting the pump into a permanent body and interchangeable pistons, the system enables quick adjustment by replacing only the piston component rather than the entire pump. This significantly reduces the time required to change pressure ratios and minimizes operational downtime.
Solution Approach 2:
Multiple pistons with different diameters can be prepared in advance and stored for quick interchange. This preliminary preparation of alternative pistons allows operators to rapidly switch between pressure ratios without extensive setup time, reducing personnel costs and operational delays.
3Adaptability or versatility
If input fluid pressure is changed to adjust output pressure, then output pressure adaptability is improved, but operational complexity increases due to additional equipment and personnel requirements
Solution Approach 1:
Instead of changing the input fluid pressure parameter (which would require additional equipment and personnel), the system changes the mechanical parameter of the piston diameter. This direct parameter change at the pump level simplifies operation by allowing pressure ratio adjustment through simple component interchange rather than complex fluid pressure control.
4Adaptability or versatility
If input fluid pressure is changed to adjust output pressure, then output pressure adaptability is improved, but personnel costs increase
Solution Approach 1:
The system changes the piston diameter parameter directly within the pump to achieve different output pressures. This eliminates the need for personnel to operate additional pressure control equipment or perform complex input pressure adjustments, thereby reducing personnel costs and operational time.

Function Achieved in This Case
This solution allows for flexible and cost-effective adjustment of output pressure without changing the input pressure, reducing equipment and personnel costs, and is applicable across various industries including oil and gas, automotive, and medical fields.
Implementation Method 1
the intensifier pumps are tuned to provide a specific pressure ratio between a low pressure side of the intensifier pump and a high pressure side of the intensifier pump. This ratio is associated with a difference in diameter between a larger diameter low pressure piston and a smaller diameter high pressure plunger.

AI summary
An intensifier pump includes a piston including at least two selectable piston diameters. Additionally, the intensifier pump includes a plunger that in operation interacts with the piston. The plunger includes a plunger diameter that is smaller than each of the at least two selectable piston diameters.
