1Productivity
If sealing liquid is stored and circulated for use, then the sealing liquid can be continuously supplied to the seal pan, but the viscosity of the sealing liquid changes due to water evaporation leading to deteriorated seal quality
Solution Approach 1:
The system continuously monitors the viscosity of the sealing liquid using a viscometer and automatically adjusts the replenishment liquid supply based on the measured viscosity values. When viscosity exceeds the predetermined range, the control unit activates the replenishment device to add liquid, thereby maintaining viscosity within the desired range and ensuring consistent seal quality during continuous operation.
Solution Approach 2:
The system changes the composition parameter of the sealing liquid by dynamically replenishing it with fresh liquid based on viscosity measurements. This parameter adjustment compensates for water evaporation effects, maintaining the sealing liquid's viscosity within the optimal range for quality band seal formation throughout continuous operation.
2Stability of the object's composition
If a viscometer is added to measure viscosity, then viscosity stability can be monitored and maintained, but the device complexity increases
Solution Approach 1:
The rotor serves multiple functions: it acts as both the measuring element of the viscometer and the stirring blade that agitates the sealing liquid. This dual functionality reduces the number of separate components needed, thereby limiting the increase in device complexity while still achieving continuous viscosity monitoring and liquid circulation.
Solution Approach 2:
The viscometer's rotor and the stirring mechanism are combined into a single integrated component. The rotor with attached stirring blades performs both viscosity measurement and liquid agitation functions simultaneously, simplifying the overall system structure compared to having separate measuring and stirring devices.
3Stability of the object's composition
If replenishment liquid is supplied based on viscosity measurement, then viscosity stability is improved, but the device complexity and operational complexity increase
Solution Approach 1:
The system automatically monitors its own sealing liquid viscosity and self-regulates by activating the replenishment pump when viscosity deviates from the predetermined range. This self-service capability eliminates the need for manual viscosity checking and adjustment, maintaining viscosity stability through automated feedback control without requiring complex external intervention systems.
