Multi-Ejector Housing with Common Suction Line Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejector arrangements are complex and inefficient due to the need for multiple ejectors to increase 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 a cartridge-based design with a control valve and non-return valve for controlled fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple ejectors are used to increase fluid capacity, then the fluid throughput capacity increases, but the construction complexity increases
Solution Approach 1:
The patent combines multiple ejectors into a single integrated housing structure with common fluid lines. The ejectors share a common suction line and common outlet line, merging what would otherwise be separate systems into one unified device. This reduces the number of external connections and simplifies the overall construction while maintaining the increased fluid capacity provided by multiple ejectors operating in parallel.
2Productivity
If multiple ejectors are used to increase fluid capacity, then the fluid throughput capacity increases, but the number of components increases
Solution Approach 1:
The patent merges multiple ejectors into a single housing unit with shared fluid pathways. Instead of having separate suction lines and outlet lines for each ejector, the design combines them into common lines that serve all ejectors simultaneously. This reduces the total number of individual components while maintaining the parallel configuration needed for high fluid throughput capacity.
3Reliability
If ejectors are arranged without common fluid lines, then each ejector operates independently, but fluid paths become uncontrolled and losses increase
Solution Approach 1:
The patent combines multiple ejectors into a single housing structure with controlled common fluid lines. The common suction line and common outlet line provide controlled pathways that guide fluid flow efficiently between all ejectors. This merging approach maintains independent operation of each ejector while eliminating uncontrolled fluid paths and associated energy losses through proper fluid guidance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration simplifies the ejector arrangement, reduces fluid losses, and allows for a compact and efficient design with adjustable capacity, enabling controlled fluid guidance and pressure energy increase across multiple ejectors.
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
