Multi-Ejector Suction Line Layout for Higher Fluid Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejector arrangements are complex and inefficient due to the need for multiple ejectors to achieve higher fluid capacity, leading to uncontrolled fluid paths and increased construction complexity.
Innovation Solution
Connecting the suction inlets of multiple ejectors to a common suction line and the motive inlets to a common motive line, with parallel arrangement of these lines to simplify construction and reduce fluid losses, and incorporating cartridges with pre-assembled components for easier mounting and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple ejectors are used to increase fluid capacity, then the fluid throughput increases, but the construction complexity increases
Solution Approach 1:
The patent combines multiple ejectors into a single integrated arrangement with common fluid lines. The suction inlets of multiple ejectors are connected to a common suction line, and the motive inlets are connected to a common motive line, merging what would otherwise be separate systems into one unified construction that achieves high fluid capacity without proportional increase in complexity
Solution Approach 2:
The common suction line and common motive line serve multiple ejectors simultaneously, making these fluid distribution systems multi-functional. A single suction line supplies all ejectors, and a single motive line provides motive fluid to all ejectors, reducing the number of separate components needed
2Productivity
If multiple ejectors are used to increase fluid capacity, then the fluid throughput increases, but the fluid path control becomes uncontrolled
Solution Approach 1:
By merging the suction paths into a common suction line and motive paths into a common motive line, the system establishes controlled, defined fluid paths. This prevents uncontrolled fluid distribution while still enabling multiple ejectors to operate at high capacity
3Productivity
If complex fluid paths are used to supply multiple ejectors, then all ejectors can be supplied, but fluid losses increase
Solution Approach 1:
The common suction line and common motive line create efficient, direct fluid paths that minimize unnecessary routing. This merging approach reduces the total length and complexity of fluid paths compared to separate individual connections, thereby reducing fluid losses while maintaining high capacity

Function Achieved in This Case
This configuration simplifies the construction of the ejector arrangement, reduces fluid losses, and allows for controlled fluid guidance, resulting in a more compact and efficient design with adjustable capacity.
Implementation Method 1
an ejector is a type of pump that uses the Venturi effect to increase the pressure energy of the fluid at the suction inlet by means of a motive fluid supplied via the motive inlet
