| Umzimba | CI,DI,WCB,ALB,CF8,CF8M |
| Idiskhi | DI,WCB,ALB,CF8,CF8M,Rubber Lined Disc,Duplex steel stainless,Monel |
| Isiqu | SS416,SS420,SS431,17-4PH |
| Isihlalo | NBR,EPDM,Viton,PTFE |
| I-Taper Pin | SS416,SS420,SS431,17-4PH |
Inkcazo yesitulo:
| Izinto eziphathekayo | Ubushushu | Sebenzisa iNkcazo |
| NBR | -23℃ ~ 82℃ | I-Buna-NBR: (i-Nitrile Butadiene Rubber) inamandla okuqina kunye nokuchasana ne-abrasion.Iphinde ixhathise kwiimveliso ze-hydrocarbon.Iyinto efanelekileyo yenkonzo eqhelekileyo yokusetyenziswa emanzini, i-vacuum, i-asidi, ityuwa, i-alkaline, i-fats, i-oyile, i-greases, i-hydraulic oils kunye ne-ethylene glycol. I-Buna-N ayinakusetyenziselwa i-acetone, ii-ketones kunye ne-nitrate okanye i-hydrocarbon ekloriniwe. |
| Ixesha lokudubula-23℃ ~120℃ | ||
| EPDM | -20 ℃~130℃ | Irabha ye-EPDM ngokubanzi: yirabha yokwenziwa kwenkonzo eqhelekileyo esetyenziswa kumanzi ashushu, iziselo, iinkqubo zemveliso yobisi kunye nezo zineeketoni, utywala, i-nitric ether ester kunye neglycerol. Kodwa i-EPDM ayikwazi ukusebenzisa i-oyile esekelwe kwi-hydrocarbon, iiminerali okanye i-solvents. |
| Ixesha lokudubula-30℃ ~ 150℃ | ||
| Viton | -10 ℃~ 180℃ | IViton yi-fluorinated hydrocarbon elastomer ekwaziyo ukumelana noninzi lweeoyile zehydrocarbon kunye neegesi kunye nezinye iimveliso ezisekwe kwipetroleum. IViton ayinakusebenzisela inkonzo yomphunga, amanzi ashushu ngaphezulu kwe 82℃ okanye ialkaline ezixineneyo. |
| PTFE | -5℃ ~ 110℃ | I-PTFE inozinzo olululo lokusebenza kweekhemikhali kunye nomphezulu awuyi kuba ncangathi.Ngaxeshanye, inepropathi ye-lubricity elungileyo kunye nokumelana nokuguga. Yimpahla efanelekileyo yokusetyenziswa kwi-acids, i-alkalis, i-oxidant kunye nezinye i-corrodents. |
| (Inner EDPM) | ||
| PTFE | -5℃~90℃ | |
| (Umgca wangaphakathi we-NBR) |
Umsebenzi:i-lever, i-gearbox, i-activator yombane, i-pneumatic actuator.
Iimpawu:
1. Uyilo lwentloko yestem ye-Double "D" okanye umnqamlezo weSquare: Ilungele ukudibanisa nee-actuator ezahlukeneyo, hambisa i-torque eyongezelelekileyo;
2.Iziqwenga ezimbini zomqhubi wesikwere: Akukho sithuba soqhagamshelwano sisebenza kuzo naziphi na iimeko ezimbi;
I-3.Umzimba ngaphandle kwesakhiwo seSakhelo: Isihlalo sinokwahlula umzimba kunye ne-fluid medium ngokuchanekileyo, kwaye ilungele ngeflange yombhobho.
