- Optimized Spring Systems: Ntsuas lub caij nplooj ntoos hlav txhav kom kaw nrawm yam tsis muaj kev cuam tshuam lub zog sib khi. Lub rooj zaum sloped tsim nyob rau hauv cryogenic li qub tuav lub siab sealing siab ntawm qhov kub thiab txias thaum ua kom ceev zog.
- Txoj Kev Ua Kom Zoo Tshaj Plaws: Ua kom muaj kev sib txuas sab hauv thiab cov txheej txheem kev sib txhuam qis (xws li PTFE) txo cov dej tsis kam. Lub Limaçon gas expander valve tau ua tiav 56-58% cov lus teb txhim kho los ntawm kev txo cov dej turbulence .
3. Advanced Control Electronics thiab Software
Niaj hnub nimno tswj systems yog revolutionizing valve dynamics:
- PWM Modulation: Pulse Width Modulation (PWM) nrog cov zaus tuav tam sim no txo qis kev siv hluav taws xob thaum tswj kev ua kom nrawm. Cov kev tshawb fawb uas siv Response Surface Methodology (RSM) pom tias optimizing PWM tsis (xws li, 12V, 15ms ncua, 5% lub voj voog ua haujlwm) tuaj yeem txiav lub sijhawm teb los ntawm 21.2%.
- Dynamic Current Control: Cov neeg tsav tsheb txawj ntse zoo li Burkert 8605 maub los kho tam sim no hauv lub sijhawm tiag tiag los them rau cov cua sov coil, ua kom muaj kev ua haujlwm zoo ib yam.
- Predictive Algorithms: Cov qauv kev kawm tshuab tshawb xyuas cov ntaub ntawv keeb kwm los kwv yees thiab preempt qeeb los ntawm kev hnav lossis ib puag ncig.
4. Thermal Management thiab Environmental Adaptation
Qhov kub thiab txias tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub valve. Cov kev daws teeb meem suav nrog:
- Cryogenic Rwb thaiv tsev: Aerospace-qib li qub siv cov pa hluav taws xob rwb thaiv tsev thiab thermal thaiv kom tswj tau qhov kub thiab txias ntawm -60 ° C thiab -40 ° C.
- Active Cooling: Microfluidic channels ua ke rau hauv lub cev valve dissipate tshav kub, tiv thaiv thermal expansion uas ua rau qeeb.
- Cov Khoom Kub-Resistant: Nitrile roj hmab seals thiab stainless-steel Cheebtsam tiv taus kev hloov pauv ntawm -196 ° C mus rau 100 ° C, ua kom muaj kev ntseeg siab hauv kev siv cryogenic thiab kub kub.
