Kufotokozera Kwachidule:

Mipira ya rabara (kuphatikizapo mipira yolimba ya rabara, mipira yayikulu ya rabara, mipira yaying'ono ya rabara ndi mipira yaying'ono yofewa ya rabara) imapangidwa makamaka ndi zinthu zosiyanasiyana zotanuka, monga rabara ya nitrile (NBR), rabara yachilengedwe (NR), rabara ya chloroprene (Neoprene), rabara ya ethylene propylene diene monomer (EPDM), rabara ya nitrile ya hydrogenated (HNBR), rabara ya silicone (Silicone), rabara ya fluoro (FKM), polyurethane (PU), rabara ya styrene butadiene (SBR), rabara ya sodium butadiene (Buna), rabara ya acrylate (ACM), rabara ya butyl (IIR), polytetrafluoroethylene (PTFE / Teflon), ma elastomers a thermoplastic (TPE/TPR/TPU/TPV), ndi zina zotero.

Mipira ya rabara iyi imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga ma valve, mapampu, zamagetsi, ndi zida zamagetsi. Pakati pawo, mipira ya pansi ndi mipiringidzo ya rabara yomwe yapangidwa bwino kwambiri ndipo ili ndi kulondola kwakukulu. Imatha kutsimikizira kuti siitulutsa madzi, siikhudzidwa ndi zinyalala, ndipo imagwira ntchito ndi phokoso lochepa. Mipira ya pansi imagwiritsidwa ntchito makamaka ngati zinthu zotsekera mu ma valve otchingira kuti atseke zinthu monga mafuta a hydraulic, madzi, kapena mpweya.

Kugwiritsa ntchito

1. Ma Vavu a Mafakitale ndi Machitidwe a Mapaipi

  • Ntchito:

    • Kutseka Kudzipatula: Kumaletsa kuyenda kwa madzi/mpweya m'ma valve a mpira, ma valve olumikizira, ndi ma valve owunikira.

    • Kulamulira Kupanikizika: Kumasunga umphumphu wa chisindikizo pansi pa kupanikizika kochepa mpaka kwapakati (≤10 MPa).

  • Ubwino Waukulu:

    • Kubwezeretsa Kolimba: Kumasintha kuti kukhale kosalala pamwamba kuti kutsekeke bwino ngati madzi sakutuluka.

    • Kukana Mankhwala: Kugwirizana ndi madzi, ma asidi/ma alkali ofooka, ndi madzi osakhala a polar.

2. Kukonza Madzi ndi Mapaipi

  • Mapulogalamu:

    • Ma valve oyandama, makatiriji a faucet, ma valve a diaphragm.

  • Kugwirizana kwa Media:

    • Madzi akumwa, madzi otayira, nthunzi (<100°C).

  • Kutsatira malamulo:

    • Imakwaniritsa miyezo ya NSF/ANSI 61 yokhudza chitetezo cha madzi akumwa.

3. Njira Zothirira Ulimi

  • Milandu Yogwiritsira Ntchito:

    • Mitu yothirira madzi, zowongolera kuthirira madzi, zobayira feteleza.

  • Magwiridwe antchito:

    • Imakana kusweka ndi madzi amchenga ndi feteleza wofewa.

    • Imapirira kukhudzana ndi UV komanso kuzizira panja (yomwe ikulimbikitsidwa ndi EPDM-blend).

4. Kukonza Chakudya ndi Zakumwa

  • Mapulogalamu:

    • Ma valve aukhondo, ma nozzle odzaza, zida zopangira mowa.

  • Chitetezo cha Zinthu:

    • Magiredi otsatira a FDA alipo kuti mulankhule mwachindunji ndi chakudya.

    • Kuyeretsa kosavuta (malo osalala opanda mabowo).

5. Zipangizo Zachipatala ndi Zowunikira

  • Maudindo Ofunika Kwambiri:

    • Mabotolo otsekera reagent, mizati ya chromatography, mapampu a peristaltic.

  • Ubwino:

    • Zotulutsa zochepa (<50 ppm), zomwe zimaletsa kuipitsidwa ndi zitsanzo.

    • Kutaya tinthu tating'onoting'ono kochepa.

6. Machitidwe Otsika a Hydraulic

  • Zochitika:

    • Zowongolera ma pneumatic, ma hydraulic accumulators (≤5 MPa).

  • Zailesi:

    • Mpweya, madzi ndi glycol zosakaniza, phosphate ester fluids (onetsetsani kuti zikugwirizana).

 

Wosagonjetsedwa ndi dzimbiri

Mipira ya CR imakhala ndi kukana bwino kwambiri ku madzi a m'nyanja ndi abwino, ma asidi ochepetsedwa ndi madzi a m'madzi, madzi oziziritsa, ammonia, ozoni, alkali. Kukana koyenera kukana mafuta a mchere, ma hydrocarbons a aliphatic ndi nthunzi.
