Nrog rau kev hloov pauv tas mus li ntawm cov txheej txheem tsim khoom, cov qauv braiding ntawm graphite packing tau dhau los ua ntau haiv neeg. Nyob ntawm cov kev ua haujlwm tshwj xeeb thiab ib puag ncig, cov qauv braiding sib txawv muaj qhov cuam tshuam ncaj qha rau ob qho tib si sealing kev ua tau zoo thiab kev pabcuam lub neej ntawm cov ntim khoom. Cov qauv braiding tseem ceeb ua haujlwm rau cov khoom ntim muaj xws li: braid- dhau-braid, txheej- dhau- txheej, tub ntxhais- braided, thiab qhaub cij- braided qauv. Cov qauv braiding tshwj xeeb thiab cov yam ntxwv ntawm graphite ntim tau piav qhia hauv qab no:
1. Braid-over-braid (Square Braid)
Txoj kev no siv yim spindles ua haujlwm ntawm ob txoj kev los tsim cov braid. Nws nta tsis muaj lub hauv paus tseem ceeb lossis lub kaum sab sauv, ua rau cov khoom lag luam nrog tus ntoo khaub lig-section. Nws cov yam ntxwv tseem ceeb yog cov qauv xoob xoob; Txawm li cas los xij, qhov looseness no muab qee qhov kev them nyiaj rau lub peev xwm rau cov ncej vibration thiab eccentricity. Cov style no feem ntau yog tshwj tseg rau kev ntim khoom nrog me me ntoo khaub lig- ntu; rau cov ntoo khaub lig loj dua - ntu, nws raug kev txom nyem los ntawm qhov tsis zoo xws li qhov ntxhib ntxhib ntxhib los mos, cov qauv hauv lub cev xoob, thiab qhov tsis zoo.
2. Txheej- dhau- txheej (Ntau- txheej Braid)
Txoj kev no siv ntau qhov sib txawv ntawm cov spindles-xws li 8, 12, 16, 24, 36, 48, lossis 60- ua haujlwm ntawm ob txoj kab los tsim cov hlua. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg yog txiav txim los ntawm cov kev qhia tshwj xeeb ntawm cov graphite packing, feem ntau ntawm ib mus rau plaub txheej. Zoo li lub braid- dhau- braid style, nws tsis muaj qhov tseem ceeb hauv nruab nrab. Txheej- dhau- txheej ntim muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom; Txawm li cas los xij, vim tias nws muaj cov txheej txheem concentric yam tsis muaj kev cuam tshuam cov fibers, nws yog qhov yooj yim rau delamination. Yog li ntawd, nws yog feem ntau siv rau cov ntsaws ruaj ruaj zoo li qub lossis hauv cov khoom siv ceev ceev.
3. Sandwich Braid
Sandwich braid qauv nta cov tub ntxhais ua los ntawm roj hmab lossis hlau, encased los ntawm txheej txheej ntawm fibers. Kev ntim khoom yog tsim los ntawm braiding cov khaubncaws sab nraud povtseg ntawm ib leeg, nrog rau tus naj npawb ntawm cov khaubncaws sab nraud povtseg txiav txim los ntawm cov kev cai tshwj xeeb. Similar to the layer-over-layer style, the sandwich braid offers good density, high mechanical strength, excellent flexibility, and effective sealing performance. Txawm li cas los xij -zoo li txheej - dhau- txheej txheej txheej -thaum txheej txheej txheej txheej dhau los, nws yog qhov yooj yim rau tev tawm. Cov qauv no feem ntau yog siv hauv cov twj thiab cov li qub, thiab tsis tshua muaj kev ua haujlwm hauv cov khoom siv sib txuas.
4. Core-Braided Structure
Core braiding yog ua los ntawm 8, 12, 16, 24, 36, 48, 60, lossis ntau dua spindles teem hla peb lossis plaub lem. Cov khoom ntim uas tau tshwm sim muaj ib qho square cross-section, ib qho chaw du, elasticity zoo heev thiab puas ua haujlwm, siab tensile zog, thiab siab ceev. Piv nrog rau cov braid ib txwm siv- dhau-braid (square braid) cov qauv, nws muaj qhov loj dua thiab ntau dua qhov sib cuag nrog cov ncej. Tsis tas li ntawd, qhov tsawg kawg nkaus qhov chaw ntawm cov fibers kom zoo dua sealing kev ua tau zoo; Txawm hais tias txheej txheej txheej txhawb nqa hnav, tag nrho cov txheej txheem ntim khoom tseem nyob twj ywm yam tsis muaj kev cuam tshuam. Qhov no sawv cev rau ib tug kuj advanced braiding technology. Thaum xaiv graphite packing, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov qauv braiding tshwj xeeb raws li cov khoom siv ua haujlwm tiag tiag kom ntseeg tau tias cov ntim khoom xa tawm nws qhov kev npaj sealing.
