1. Graphite Packing yam piav qhia
Muaj cov nram qab no 3 hom fillers feem ntau siv hauv li qub
Cov packing siv nyob rau hauv qhov project no yog ib qho qhib hom nyob rau hauv daim duab 1 thiab lub nplhaib-shaped packing nyob rau hauv daim duab 3. Cov duab tiag tiag yog raws li nram no:
Daim duab 1 Ib qho qhib hom packing
Daim duab 3 Packing nplhaib packing
Kev siv lub luag haujlwm ntawm ob lub ntim khoom saum toj no yog tib yam, qhov sib txawv nyob rau hauv qhov sib txawv ntawm kev siv scenarios. Lub pob qhib ib zaug yog tsim los hloov cov ntim khoom thaum lub sij hawm tu lub valve. Kev ntim khoom tuaj yeem hloov pauv hauv online, thiab lub nplhaib packing yog tsim rau overhauling lub valve. Siv rau disassembly thiab kho.
2. Kev piav qhia ntawm graphite packing yam ntxwv
Raws li cov kev xav tau ntawm kev tsim cov khoom siv muab tub lim, cov muab tub lim yuav tsum muaj qee yam resilience npaum li cas, yog li yuav muaj qhov rov ua haujlwm ntawm sab hauv mus rau sab nraud tom qab tsim cov filling. Qhov saum toj no-hais ob hom ntawm ib leeg-qhib hom graphite muab tub lim yog braided muab tub lim uas nws cov txheej txheem molding yog braided los ntawm ntau graphite fibers, thiab cov resilience yog absorbed los ntawm braided qhov sib txawv thiab tsis muaj ib qho cuab yeej cuab tam ntawm longing rau expansion. Packing nplhaib-type packing graphite yog ib qho compact packing nrog ib tug kuj compact sab hauv. Tom qab lub sij hawm ntev ntawm kev sawv ntsug, lub zog sab hauv yuav pom cov kab nrib pleb ntawm qhov ntim thiab tso tawm qhov kev ntxhov siab no. Hom kev muab tub lim no yuav nyob ruaj khov thiab tsis hloov tom qab muaj qee qhov tawg tau tsim. Thaum nws yog compressed dua, qhov tawg ploj thiab tus nqi rov ua tau raws li qhov yuav tsum tau ua.
Cov hauv qab no yog cov kev cai rau kev hloov pauv graphite rings

3. Hais txog kev siv graphite packing
Cov graphite packing yog siv nyob rau hauv qhov chaw kaw ntawm lub valve qia thiab lub packing caj pas, thiab cov packing yog nyob rau hauv lub compressed lub sij hawm ua hauj lwm. Txawm hais tias nws yog ib qho qhib hom packing lossis ib lub nplhaib packing hom packing, tsis muaj qhov sib txawv hauv kev ua haujlwm ntawm lub xeev compressed.
