Hauv kev tswj cov kua dej hauv kev lag luam, kev xaiv cov khoom siv lub rooj zaum txhais tau hais tias lub pob valve qhov kev ua tau zoo ciam teb thiab daim ntawv thov tsim nyog. Mos zaum thiab hlau zaum pob li qub sawv cev rau ob pawg tseem ceeb nrog qhov sib txawv. Cov kev ntsuam xyuas hauv qab no rhuav tshem qhov sib txawv ntawm plaub qhov tseem ceeb:
Sealing Mechanism thiab Khoom Siv Khoom Siv
Lub rooj zaum pob valve siv cov khoom siv tsis yog xim hlau xws li PTFE, RPTFE, PEEK, Nylon, lossis roj hmab elastomers. Lub hauv paus ntsiab lus sealing cia siab rau cov elastic deformation ntawm cov ntaub ntawv mos los sau cov microscopic deg irregularities ntawm lub pob, ua tiav lub npuas nruj kaw nrog zero toxity.
Hlau zaum pob li qub tsim ob lub rooj zaum thiab pob ntim qhov chaw los ntawm cov khoom siv hlau zoo li stainless hlau, Stellite, lossis npib tsib xee raws alloys, feem ntau hardened ntawm High Velocity Oxygen Fuel (HVOF) txau. Lub foob nyob ntawm siab precision lapping ntawm cov hlau nto thiab elastic yas deformation generated los ntawm preload, ua ib tug micron theem kab los yog nqaim band hu seal.
Kub thiab siab muaj peev xwm
Temperature resistance yog qhov tseem ceeb sib txawv. Txwv los ntawm cov khoom siv lub cev ntawm cov khoom tsis yog xim hlau, cov rooj zaum muag muag feem ntau ua haujlwm ntawm -50℃thiab 200 degree. Cov ntaub ntawv ua haujlwm siab zoo li PEEK tuaj yeem tiv taus txog 260 degree. Tshaj li cov kev txwv no, cov ntaub ntawv muaj feem xyuam rau kev laus, carbonization, lossis melting. Hlau zaum pob li qub leverage lub cev muaj zog ntawm cov hlau los tswj qhov chaw cryogenic mus txog -196℃thiab ultra kub kub siab tshaj 500℃txog 800 degree.
Hais txog kev ua haujlwm siab, cov rooj zaum muag muag feem ntau yog siv rau hauv qhov chaw qis rau nruab nrab siab. Nyob rau hauv lub siab tsis tshua muaj siab, cov ntaub ntawv mos yog raug rau txias txaus deformation los yog extrusion. Hlau zaum pob li qub tau tsim tshwj xeeb rau kev kub siab, siab kub siab, thiab qhov chaw hnyav nrog kev hloov pauv siab heev.
Hnav Resistance thiab Media Adaptability
Hlau zaum pob li qub muaj qhov tshwj xeeb tiv thaiv kev yaig, abrasion, thiab corrosion. Lawv tsim nyog rau kev tuav cov khoom qias neeg uas muaj cov khoom siv, hmoov, slurries, los yog cov khoom abrasive heev. Lawv kuj muaj kev nyab xeeb hluav taws zoo dua; cov hlau rau hlau foob tswj kev ncaj ncees txawm tias cov ntsaws ruaj ruaj yuav raug puas tsuaj los ntawm qhov kub thiab txias thaum muaj hluav taws kub.
Mos zaum pob li qub muab kev sib khi zoo heev rau kev tshaj tawm huv. Lawv qhov chaw sealing tau yooj yim khawb los yog cuam tshuam los ntawm cov khoom sib txuas thaum raug cov kua dej uas muaj cov khib nyiab nyuaj. Cov rooj zaum muag muag muaj qhov txwv tsis pub muaj kev nyab xeeb txog hluav taws tshwj tsis yog tias muaj kev tsim hluav taws xob tshwj xeeb.
Kev khiav hauj lwm Torque thiab Economics
Qhov qis coefficient ntawm kev sib txhuam hauv cov ntaub ntawv mos tso cai rau cov rooj zaum hauv pob li qub ua haujlwm nrog lub zog qis heev. Qhov no txo cov kev siv zog ntawm lub cev rau kev siv phau ntawv thiab tso cai rau kev xaiv me me, tus nqi zoo actuators hauv automated systems. Hlau zaum pob li qub pom cov hlau ntau dua rau hlau kev sib txhuam tsis kam, yuav tsum muaj kev ua haujlwm ntau dua thiab ua kom muaj zog ntau dua.
Los ntawm thawj qhov kev xav ntawm kev yuav khoom, cov khoom muag muag pob li qub yog qhov pheej yig dua li qhov nyuaj, siab precision hlau zaum li qub. Los ntawm kev xav txog tus nqi lifecycle, lub neej kev pabcuam txuas ntxiv thiab txo kev saib xyuas ntawm cov hlau zaum hauv cov xwm txheej hnyav feem ntau tau txais txiaj ntsig zoo dua kev lag luam mus sij hawm ntev.
Xaus
Mos zaum pob li qub yog qhov kev xaiv zoo tshaj plaws rau kev huv, ambient kub / siab siv qhov twg xoom to yog qhov tseem ceeb.
Hlau zaum pob li qub yog qhov tseem ceeb hauv kev lag luam hnyav kev daws teeb meem rau cov xwm txheej huab cua uas muaj qhov kub siab, siab siab, muaj zog corrosion, los yog cov khoom me me.
Kev xaiv engineering siv tswv yim yuav tsum muaj kev ntsuam xyuas zoo raws li lub cev thiab tshuaj lom neeg cov khoom ntawm cov xov xwm, qhov kub thiab txias tsis kam, thiab kev tswj tus nqi.
