Incazelo emfushane:

Amabhola erabha (kufaka phakathi amabhola erabha aqinile, amabhola amakhulu erabha, amabhola amancane erabha kanye namabhola amancane erabha athambile) enziwe kakhulu ngezinto ezahlukahlukene zokunwebeka, njengerabha ye-nitrile (NBR), irabha yemvelo (NR), irabha ye-chloroprene (Neoprene), irabha ye-ethylene propylene diene monomer (EPDM), irabha ye-nitrile ene-hydrogenated (HNBR), irabha ye-silicone (Silicone), irabha ye-fluoro (FKM), i-polyurethane (PU), irabha ye-styrene butadiene (SBR), irabha ye-sodium butadiene (Buna), irabha ye-acrylate (ACM), irabha ye-butyl (IIR), i-polytetrafluoroethylene (PTFE / Teflon), ama-elastomer e-thermoplastic (TPE/TPR/TPU/TPV), njll.

Lawa mabhola enjoloba asetshenziswa kabanzi ezimbonini eziningi ezifana nama-valve, amaphampu, izinto zikagesi, kanye nezinto zikagesi. Phakathi kwawo, amabhola angaphansi komhlaba ayizindilinga zerabha eziye zacutshungulwa ngokunembile futhi zinokunemba okuphezulu kakhulu. Angaqinisekisa ukuthi uphawu aluvuzi, awazweli ukungcola, futhi asebenza ngomsindo ophansi. Amabhola angaphansi komhlaba asetshenziswa kakhulu njengezinto zokuvala kuma-valve okuhlola ukuvala imidiya efana namafutha e-hydraulic, amanzi, noma umoya.

    • Imelana nokuchayeka kwe-UV kanye nesimo sezulu sangaphandle (kunconywa ukuxubana kwe-EPDM).

4. Ukucubungula Ukudla Neziphuzo

  • Izicelo:

    • Amavalvu okuhlanzeka, ama-nozzle okugcwalisa, imishini yokupheka.

  • Ukuphepha Kwezinto Ezibalulekile:

    • Amazinga ahambisana ne-FDA ayatholakala ukuze kuthintanwe ngqo ngokudla.

    • Ukuhlanza okulula (indawo ebushelelezi engenazimbobo).

5. Izinsimbi Zelebhu Nokuhlaziya

  • Izindima Ezibalulekile:

    • Amabhodlela okuvala ama-reagent, amakholomu e-chromatography, amaphampu e-peristaltic.

  • Izinzuzo:

    • Izinto ezikhishwayo eziphansi (<50 ppm), ezivimbela ukungcoliswa kwesampula.

    • Ukuchitheka okuncane kwezinhlayiya.

6. Izinhlelo ze-Hydraulic Ezinomfutho Ophansi

  • Izimo:

    • Izilawuli zomoya, ama-hydraulic accumulator (≤5 MPa).

  • Imidiya:

    • Umoya, izingxube zamanzi-glycol, uketshezi lwe-phosphate ester (qinisekisa ukuhambisana).
