Independent Piston Pump Compensators for Sticky Material Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional piston pumps are inefficient in transporting sticky or dry materials due to high viscosity, leading to unstable flow rates and potential clogging, resulting in non-continuity and uniformity issues during material transfer.
Innovation Solution
A system featuring a filling mechanism using gravity or external forces to fill chambers, independent piston control for stable movement, and compensators to maintain constant flow, along with a self-cleaning gas line for sticky materials, ensures continuous and uniform flow by preventing the 'pump brake' and addressing clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional piston pumps are used to transport materials, then the pump structure is simple, but the flow rate stability deteriorates due to pump brake and clogging
Solution Approach 1:
The pump is divided into multiple independent cylinders (at least two cylinders) with independent pistons, each capable of independent reciprocating motion. This segmentation allows one cylinder to compensate for flow interruptions in another, eliminating the pump brake effect and maintaining continuous stable flow.
Solution Approach 2:
The system includes a feeding mechanism that pre-fills the cylinder chambers with material before the pistons begin their pumping action. This preliminary filling ensures that material is ready and available when pumping starts, preventing initial clogging and flow interruptions.
2Productivity
If piston pumps operate with high speed to increase productivity, then output increases, but flow rate uniformity deteriorates due to pump brake effects
Solution Approach 1:
With at least two cylinders operating in coordinated reciprocating motion, the system ensures continuous material delivery without interruption. When one piston is delivering material, the other is refilling or delivering, eliminating dead zones and maintaining continuous useful action regardless of operating speed.
Solution Approach 2:
The system allows dynamic coordination of piston movements where pistons can operate at different phases or speeds. This dynamic control enables optimization of both productivity and flow uniformity by adjusting the reciprocating motion parameters of each piston independently.
3Use of energy by moving object
If feeding mechanism uses gravity force to fill chambers, then energy consumption is low, but filling efficiency deteriorates for sticky or dry materials
Solution Approach 1:
The feeding mechanism uses periodic vibration or oscillation to assist gravity in filling chambers. This periodic action temporarily reduces friction and adhesion forces for sticky or dry materials, enabling complete and efficient filling without requiring continuous high energy input.
Solution Approach 2:
Vibration is applied to the feeding mechanism or chamber walls to prevent material bridging and arching in hoppers. This mechanical vibration helps sticky and dry materials flow freely into chambers under gravity, significantly improving filling efficiency without adding substantial energy consumption.

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 system achieves stable and continuous flow of less pumpable materials by preventing flow interruptions and maintaining a consistent flow rate through independent piston control and compensators, while the self-cleaning system ensures efficient handling of sticky materials.
Implementation Method 1
a filling mechanism for the less pumpable material may be by using gravity force (weight) to fill a chamber
Implementation Method 2
The filling mechanism may be assisted by external mechanisms such as sloped walls or any external force such as pressurized gas/liquid, vibration, etc.
Implementation Method 3
The filling mechanism may be assisted by external mechanisms such as sloped walls or any external force such as pressurized gas/liquid, vibration, etc.
Implementation Method 4
a self cleaning system with a gas line (with, for example, Nitrogen or air) may be used to remove all types of deposits and/or settled materials. This gas line is supplying sufficient pressure to release and/or unsettle those materials
