Fluid Circulation Pump with Circular Lips for Pressure Loss Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid circulation pumps with traditional non-return valves experience pressure loss and require additional components, limiting their efficiency and self-priming capacity.
Innovation Solution
A fluid circulation pump design featuring circular lips that vary the volume of a chamber to manage fluid flow without a non-return valve at the inlet, allowing free passage during suction and preventing backflow during discharge, thereby minimizing pressure loss and enhancing self-priming capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional non-return valves are used in the pump, then fluid flow direction control is achieved, but pressure loss increases and device complexity increases
Solution Approach 1:
The invention extracts and eliminates the traditional non-return valve component from the pump system. Instead of using a valve to control fluid direction, the patent uses the moving part with integrated lips that perform the same function through their geometric configuration and movement, thereby removing the source of pressure loss and component complexity
Solution Approach 2:
The invention merges the function of the non-return valve with the moving part itself. The lips on the moving part are designed to perform both the pumping action and the one-way flow control function, combining multiple functions into a single component to reduce overall system complexity and eliminate additional pressure drops from multiple components
2Reliability
If traditional non-return valves are used in the pump, then fluid flow direction control is achieved, but device complexity increases
Solution Approach 1:
The invention extracts and eliminates the traditional non-return valve component from the pump system. Instead of using a valve to control fluid direction, the patent uses the moving part with integrated lips that perform the same function through their geometric configuration and movement, thereby removing the source of pressure loss and component complexity
Solution Approach 2:
The moving part is designed with universal functionality, serving both as the pumping element and as the flow direction control mechanism. The lips on the moving part perform multiple functions: creating pressure differential, controlling fluid intake, and preventing backflow, eliminating the need for separate specialized components
3Reliability
If non-return valves are used at inlet and outlet, then fluid circulation is controlled, but pressure drop increases
Solution Approach 1:
The invention extracts and eliminates the traditional non-return valve component from the pump system. Instead of using a valve to control fluid direction, the patent uses the moving part with integrated lips that perform the same function through their geometric configuration and movement, thereby removing the source of pressure loss and component complexity
Solution Approach 2:
The moving part with its lips performs self-service by automatically controlling fluid flow direction through its own movement and geometry. The lips create pressure differentials and seal against the chamber walls to prevent backflow without requiring external valve components, making the system self-regulating and eliminating additional pressure drops
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
The pump operates with reduced pressure loss during fluid admission, improving efficiency and self-priming capacity, allowing for effective transfer of both gases and liquids without the need for additional valves, thus enhancing overall performance.
Implementation Method 1
the moving part varies the volume of the first space in such a way that this first space is: either put under depression and open towards the fluid suction inlet to suck fluid towards this space... or put under compression and open towards the discharge outlet only to discharge fluid from the first space
Implementation Method 2
the first downstream circular lip provides a seal preventing the passage of fluid from said discharge outlet to said first space... the first upstream circular lip provides a seal preventing the passage of fluid from said first space to said suction inlet

AI summary
Fluid circulation pump (100) comprising a suction inlet (41), a delivery outlet (42) and a movable part (45) that can move in the chamber (44). The pump (100) comprises first upstream (120a) and downstream (121a) circular lips such that: - over a first portion (P1) of the movement of said movable part (45) in the chamber (44), the first upstream circular lip (120a) then allows a free flow of fluid between the first space (123a) and the suction inlet (41); and that - over a second portion (P2) of said movement, the first upstream circular lip (120a) provides sealing that prevents the flow of fluid towards the suction inlet (41), the first downstream circular lip (121a) allowing the flow of fluid from the first space (123a) towards said delivery outlet (42) and preventing the flow of fluid towards said first space (123a).
