Izinto ezisetyenziswa kwiindawo eziphambili:
| Iinxalenye | Izinto eziphathekayo |
| Umzimba | I-CI, DI, WCB, ALB, CF8, CF8M |
| Idiski | I-DI, i-WCB, i-ALB, i-CF8, i-CF8M, i-Rubber Lined Disc, i-Duplex stainless steel, i-Monel |
| Isiqu | I-SS416, i-SS420, i-SS431, i-17-4PH |
| Isihlalo | I-NBR, i-EPDM, iViton, i-PTFE |
| Iphini yeTaper | I-SS416, i-SS420, i-SS431, i-17-4PH |
Iinkcukacha zeSihlalo:
| Izinto eziphathekayo | Ubushushu | Inkcazo yokusetyenziswa |
| I-NBR | -23℃ ~ 82℃ | I-Buna-NBR: (Irabha ye-Nitrile Butadiene) inamandla okutyhafa kunye nokumelana nokukrala. Ikwamelana neemveliso ze-hydrocarbon. Yinto efanelekileyo yokusetyenziswa emanzini, kwi-vacuum, kwi-asidi, kwiityuwa, kwi-alkalines, kwimafutha, kwi-oyile, kwiigrisi, kwiioyile ze-hydraulic nakwi-ethylene glycol. I-Buna-N ayinakusetyenziselwa i-acetone, kwi-ketones nakwi-hydrocarbons ezine-nitrate okanye ezine-chlorine. |
| Ixesha lokudubula -23℃ ~120℃ | ||
| I-EPDM | -20 ℃ ~ 130℃ | Irabha ye-EPDM eqhelekileyo: yirabha yokwenziwa elungileyo esebenza ngokubanzi esetyenziswa kumanzi ashushu, iziselo, iinkqubo zemveliso yobisi kunye nezo ziqulethe ii-ketones, utywala, ii-ester ze-nitric ether kunye ne-glycerol. Kodwa i-EPDM ayinakusetyenziselwa iioyile ezisekelwe kwi-hydrocarbon, iiminerali okanye izinyibilikisi. |
| Ixesha lokudubula - 30℃ ~ 150℃ | ||
| IViton | -10 ℃ ~ 180℃ | I-Viton yi-elastomer ye-hydrocarbon ene-fluorinated enokumelana kakuhle neeoyile ezininzi ze-hydrocarbon kunye neegesi kunye nezinye iimveliso ezisekwe kwi-petroleum. I-Viton ayinakusetyenziselwa inkonzo yomphunga, amanzi ashushu angaphezu kwama-82℃ okanye i-alkalines ezixineneyo. |
| I-PTFE | -5℃ ~ 110℃ | I-PTFE inamandla okusebenza kakuhle kweekhemikhali kwaye umphezulu wayo awuyi kunamathela. Kwangaxeshanye, inamandla okuthambisa kwaye iyamelana nokuguga. Yinto elungileyo yokusetyenziswa kwii-asidi, ii-alkali, ii-oxidant kunye nezinye izinto ezibolayo. |
| (Inner liner EDPM) | ||
| I-PTFE | -5℃~90℃ | |
| (Inner liner NBR) |
Umsebenzi:i-lever, i-gearbox, i-electrical actuator, i-pneumatic actuator.
Iimpawu:
1. Uyilo lwentloko yesiqu se-Double “D” okanye i-Square cross: Lula ukuqhagamshela kwii-actuators ezahlukeneyo, lunika i-torque engakumbi;
2. Umqhubi wesikwere sesiqu seenxalenye ezimbini: Akukho sithuba sisebenzayo kuyo nayiphi na imeko embi;
3. Umzimba ongenasakhiwo sesakhelo: Isihlalo singahlula umzimba kunye nolwelo oluphakathi ngokuchanekileyo, kwaye kulula ngeflangi yombhobho.
