Hupenyu hwesevhisi hunokanganiswa nezvose zvinotevera zvinhu: -saizi, kudzvanywa, tembiricha, dhigirii rekudzvanya kushanduka uye kushanduka kwemafuta, mhando yemedia, frequency yebhasikoro, velocity yemedia & nekumhanyisa kwekushanda kwevharuvhu.
Iyo inotevera chigaro & chisimbiso zvinhu zvinogona kushandiswa akasiyana mavharuvhu akadai bhora, plug, butterfly, gedhi, cheki mavharuvhu etc.
Zvinhu zvinonyanya kuzivikanwa zvechigaro chevhavhavhavhavha kuisa mhete zvinhu zvichave
PTFE, RTFFE,PEEK,DEVLON/NYLON,PPL zvinoenderana nekumanikidza kwakasiyana,saizi uye nemamiriro ekushanda.
Iyo inonyanya kuzivikanwa zvinhu zvebhora vharafu yakapfava sealing material ichave
ichave BUNA-N, PTFE, RPTFE,VITON,TFM, nezvimwe.
Kunyora mashoma akakosha maitiro:
BUNA-N (HYCAR kana Nitrile)- Tembiricha yemhando ndeye -18 kusvika 100 ℃ yakanyanya.Buna-N ndeye general-chinangwa polymer iyo ine kumira zvakanaka kumafuta, mvura, zvinonyungudutsa uye hydraulic zvinwiwa.Inoratidzawo kudzvanyirira kwakanaka, kubvongodzwa kweabrasion, uye kusimba kwesimba. Izvi zvinoshanda zvakanyanya munzvimbo dzinoshandiswa kune parafini, mafuta acids, mafuta, doro kana glycerin zviripo, sezvo zvisingakanganwe zvachose.Haifanirwe kushandiswa kutenderedza yakakwira polar solvents (acetones, ketones), chlorinated hydrocarbons, ozone kana nitro hydrocarbons.Hycar itema muruvara uye haifanirwe kushandiswa uko kushanduka kwemavara kusingabvumirwe.Inoonekwa seyakafanana inotsiva neoprene.Misiyano mikuru ndeiyi: Buna-N ine tembiricha yepamusoro;neoprene inonyanya kurwisa mafuta.
EPDM- Tembiricha chiyero kubva -29 ℃ kusvika 120 ℃.EPDM ipolyester elastomer yakagadzirwa kubva ethylene-propylene diene monomer.EPDM ine yakanaka abrasion uye kubvarura kuramba uye inopa yakanakisa makemikari kuramba kune akasiyana maasidhi uye alkaline.Inokonzeresa kurwiswa neoiri uye haikurudzirwe kune zvinoshandiswa zvinosanganisira petroleum oiri, yakasimba asidhi, kana alkaline yakasimba.EPDM haifanirwe kushandiswa pamitsetse yemhepo yakamanikidzwa.Iyo ine yakasarudzika yakanaka mamiriro ekunze kuchembera uye ozone kuramba..Izvo zvakanakira ketoni uye doro.
PTFE (TFE yeTeflon)- PTFE ndiyo inonyanya kupikisa makemikari pamapurasitiki ese.Iyo inewo yakanakisa yekupisa uye magetsi ekudzivirira emagetsi.PTFE's mechanical properties yakaderera kana ichienzaniswa nemamwe mapurasitiki einjiniya,asi maitiro ayo anoramba ari pamazinga anobatsira pamusoro petembiricha yakakura (-100 ℃ kusvika 200 ℃, zvichienderana nemhando uye kushandiswa).
RTFE (Yakasimbiswa TFE/RPTFE)- Yakajairika tembiricha renji -60 ℃ kusvika 232 ℃.RPTFE/RTFE inosanganiswa nechikamu chakasarudzwa chefiber glass filler kuti ivandudze simba uye kurwisana neabrasive kupfeka, kutonhora kuyerera, uye kupindira muzvigaro zvakaumbwa.Kusimbisa kunobvumira kushandiswa kwepamusoro-soro uye tembiricha kupfuura TFE isina kuzadza.RTFE haifanirwe kushandiswa mumashandisirwo anorwisa girazi, senge hydrofluoric acid uye inopisa yakasimba caustics.
CARBON AKAZADZWA TFE- Tembiricha siyana -50 ℃ kusvika 260 ℃.Carbon yakazadzwa TFE yakanakisa chigaro zvinhu zvekushandisa chiutsi pamwe nekunyanya kushanda kwemafuta-based thermal fluids.Mafirita anosanganisira graphite anogonesa ichi chigaro kuti chive nehupenyu huri nani kutenderera pane zvimwe zvakazadzwa kana kusimbiswa TFE zvigaro.Kemikari kuramba yakaenzana nezvimwe zvigaro zveTFE.
TFM1600-TFM1600 ishanduro yakagadziridzwa yePTFE inochengetedza makemikari akasiyana-siyana uye kupisa kupisa zvinhu zvePTFE, asi ine yakanyanya kuderera yakanyunguduka viscosity. service range yeTFM1600 iri -200℃ kusvika 260℃.
TFM1600+20%GF-TFM1600+20% GF is a fiber glass reinforced version yeTFM1600.Zvakafanana neRTFE, asi nerubatsiro rweTFM1600, iyo girazi yakazadzwa vhezheni inopa yakakura abrasion kuramba uye inonatsiridza kugadzikana pakumanikidza kwakanyanya.
TFM4215- TFM4215 is an elector graphitized carbon filled TFM material.Iyo kabhoni yakawedzerwa inovandudza kugadzikana kwepamusoro-soro uye kusanganiswa kwekushisa.
VITON(Fluorocarbon, FKM, kana FPM)- Tembiricha chiyero kubva-29 ℃ kusvika 149 ℃.Fluorocarbon elastomer inowirirana nehupamhi hwemakemikari.Nekuda kwekuenderana kwekemikari uku kunoenderana nekuwanda kwemazinga uye tembiricha, fluorocarbon elastomer yave kugamuchirwa zvakanyanya sechinhu chekuvakira zvigaro zvegedhi revharuvhu. .Iyo inonyanya kunaka mu hydrocarbon service.Rudzi igrey (dema) kana dzvuku uye rinogona kushandiswa pamitsara yemapepa akacheneswa.Fluorocarbon(VITON)haikodzere kusvira kana sevhisi yemvura inopisa,zvisinei, in o-ring form inogona kugamuchirwa kumitsetse yehydrocarbon yakasanganiswa nemvura inopisa zvichienderana. parudzi/rudzi.Zvezvigaro zvezvigaro FKM inogona kupa zvakanyanya kuramba kune inopisa mvura-yekubvunza mugadziri.
PEEK-Polyetheretherketone-high pressure semi-rigid elastomer.Inonyatsokodzera kushandiswa kwepamusoro uye basa rekushisa.Zvakare inopa yakanaka kwazvo ngura kuramba.Temperature rating -56.6℃ kusvika 288℃.
DELRIN/POM-Special Delrin zvigaro zvinopiwa kumanikidziro epamusoro uye kuderera kwekushisa kwebasa.Inogona kushandiswa mumhepo yakakwirira, mafuta uye mamwe magasi emagetsi asi hazvina kukodzera kune yakasimba oxidizing.Temperature rating-50℃ kusvika 100 ℃.
NYLON/DEVLON-Nylon (polyamide) zvigaro zvinopihwa kune yakanyanya kudzvanywa uye yakaderera tembiricha sevhisi.Inogona kushandiswa mukupisa kwemhepo, mafuta uye mamwe gasi midhiya asi haina kukodzera kune yakasimba oxidizing.Tembiricha chiyero -100 ℃ kusvika 150 ℃.Devlon ine hunhu hwenguva refu yepasi yekunyura kwemvura, yakasimba kumanikidza kuramba uye yakanaka kudzoreredza murazvo.Devlon inoshandiswa zvakanyanya mumapaipi emafuta uye gasi echisikigo kunze kwenyika kune trunnion ball valve class 600 ~ 1500lbs.
