Roj hmab sheath rau txoj kev sib txuas ntawm hluav taws xob cia converter
1. Cov Khoom Txheej Txheem
Cov roj hmab sheath, tsim tshwj xeeb rau cov hluav taws xob txuas ntawm kev ua kom cov hluav taws xob sib txuas rau cov xov hlau, cov xaim, thiab cov txuas. Nws cov haujlwm ntau ntau ntau, suav nrog rwb thaiv tsev, kev tiv thaiv, yog pom zoo ntawm Circuit Court, yog li lees paub qhov kev ua haujlwm ntawm lub zog sib hloov.
2. Cov qauv qauv
- Txheej roj hmab txheej: Tsim los ntawm qib siab - zoo roj hmab cov khoom muaj zog rau lawv cov kev tiv thaiv zoo, thiab muaj zog heev - diene monomer (epdm) roj hmab thiab roj hmab silicone roj hmab. Cov txheej no ua raws li cov ntawv sau ua ke, tiv thaiv cov txheej txheem sab hauv xws li ya raws, plua plav, thiab tshuaj lom neeg uas yuav muaj kev puas tsuaj rau Circuit Court. Ib qho ntxiv, nws tuaj yeem ua kom tau ib txwm muaj kev ntxhov siab xws li kev sib txhuam, extrusion, thiab kev sib tsoo, muaj txiaj ntsig zoo rau sab hauv.
- Sab hauv liner lossis insulating txheej: Sau ntawm cov ntaub ntawv muag muag thiab hloov tau cov ntaub ntawv insulating, feem ntau polytetrosraToroethylene (PTFE) thiab polyethylene (PE). Cov txheej no tau sib chwv nrog cov xov hlau, cov xaim, lossis cov sib txuas, muab ib txheej ntxiv ntawm rwb thaiv tsev. Los ntawm kev ua li ntawd, nws tsis tsuas yog txo qis kev pheej hmoo ntawm cov dej xau tam sim no tab sis kuj cushions lub siab txheej ntawm cov kab sab hauv, tiv thaiv kev puas tsuaj los ntawm extrusion ntau heev.
- Cov Qauv Txheej Txheem Tshwj Xeeb: Qee cov roj hmab sheaths tshwj xeeb cov qauv kev tsim qauv. Piv txwv li, SNAP - cov pob tw, lossis khi - lossis khi - los yog kho cov roj hmab ntawm cov roj hmab ntawm cov ntsiab lus sib txuas. Qhov no ua kom pom tseeb tias cov txaj nyob ruaj ruaj nyob rau hauv qhov chaw thaum ua haujlwm, tsis muaj kev phom sij ntawm kev txo qis lossis kev txav chaw. Ntxiv mus, sib khi daim di ncauj los yog sib khi zuaj yog ntxiv los txhim kho kev ua yeeb yam, muaj zog tiv thaiv noo noo thiab impurities los ntawm infiltrating.
3. Cov khoom lag luam
- Rwb thaiv tsev kev tiv thaiv: Los ntawm kev tsim lub cev lub cev ntawm cov chaw sib txuas sib txuas thiab cov roj hmab sab nraud, cov roj hmab pov tseg ua ke tiv thaiv cov hluav taws xob muaj teeb meem thiab cov tub ceev xwm ntawm Circuit Court luv - circuits. Qhov no yog qhov tseem ceeb rau kev tswj hwm hluav taws xob kev nyab xeeb ntawm lub zog cia siab.
- Dej nyab thiab plua plav: Hlis sealing zoo nkauj muaj peev xwm, cov roj hmab sheath tuaj yeem thaiv cov kuab paug xws li noo noo thiab hmoov av los ntawm kev nkag mus rau thaj chaw sib txuas. Qhov no pab kom zam cov teeb meem xws li kev ua hluav taws xob tsis zoo thiab corrosion ua los ntawm cov hmoov av sib txawv, thaum kawg txuas cov kev pabcuam lub neej ntawm cov khoom siv.
- Hluav Taws Xob Interromiction Kuj: Qee cov ntaub ntawv roj hmab sheath tau tsim nrog cov khoom siv hluav taws xob tshwj xeeb. Cov khoom no pab kom cov hnab riam los txo qhov cuam tshuam ntawm cov hluav taws xob sab nraud hluav taws xob ntawm cov paib sib kis tau. Ib txhij, nws yuav tau txau lub hluav taws xob hluav taws xob tsim los ntawm Circuit Court nws tus kheej, yog li txhim kho lub zog hluav taws xob ntawm lub zog sib hloov.
- Kev Tiv Thaiv Txhua Yam: Cov roj hmab sheath kev ua raws li cov ntaub thaiv cov ntaub thaiv tawm tsam kev puas tsuaj, xws li ua paug, txiav, thiab extrusion. Los ntawm kev tiv thaiv kev ncaj ncees ntawm cov xov hlau, cables, thiab cov txuas, nws pab tiv thaiv kom tsis txhob muaj qhov tsis yooj yim.
- Buffering thiab kev co damping: Thaum lub sijhawm ua haujlwm ntawm lub zog cia hloov dua siab, kev co thiab kev cuam tshuam yog kev tsis pom kev. Cov roj hmab shibe ua lub luag haujlwm tseem ceeb hauv buffering thiab dampening cov kev sib tw no, txo lawv qhov kev cuam tshuam rau ntawm qhov kev sib txuas ntawm cov kab sib txuas thiab ua kom muaj kev ruaj ntseg ntawm kev sib txuas.
4. Cov Khoom Siv Khoom Siv Cov Lus Qhia
- Roj Teeb Kev Txuas: Thaum nws los txog rau cov cables sib txuas cia khoom roj teeb thiab cov khoom siv hluav taws xob muab hluav taws xob, uas feem ntau nqa hluav taws xob loj, cov roj hmab sheath yog tsis tseem ceeb. Nws ntseeg tau tias cov rwb thaiv tsev thiab kev tiv thaiv cov cable no, tiv thaiv lawv los ntawm cov peev xwm kev puas tsuaj los ntawm cov roj teeb, thiab ntau dua. Qhov no, nyob rau hauv lem, lav kev sib raug zoo thiab txuag hluav taws xob ntawm hluav taws xob hluav taws xob.
- Kos Npe Kis Kab: Rau lub teeb liab cables uas txuas ntau yam kev tswj hwm thiab sensors nyob rau hauv lub zog cia converter, cov hnab roj hmab uas tseem ceeb heev rau kev tiv thaiv kev cuam tshuam rau cov cim. Los ntawm kev tswj cov raug thiab muaj kev sib luag ntawm cov kis tau teeb meem, nws ua rau lub zog sib hloov mus ua kev tswj hwm ib txwm thiab saib xyuas cov haujlwm.
- Lub hwj chim tswv yim thiab cov kab tso zis: Cov ntaub ntawv thiab cov zis tso zis sib txuas nrog lub zog hluav taws xob lossis kev tiv thaiv hauv qab qib siab - voltage thiab siab - cov xwm txheej. Qhov no ua kom muaj kev ruaj ntseg sib txuas ntawm lub zog cia hloov dua siab tshiab thiab lub zog sab nraud.
