Izinto ezisetshenziswa kakhulu zenjolobaama-hydraulic sealsirabha ye-nitrile NBR.Ngaphezu kwalokho, uma kunezidingo ezikhethekile zokumelana nokushisa nokumelana namafutha, i-fluororubber ingasetshenziswa;Uma kunezidingo ezikhethekile zokumelana nokugqoka nokumelana nokucindezela, i-AU/EU (irabha ye-polyurethane) ingakhethwa.
1. Izinhlobo zemidiya yokusebenza yezimpawu ze-hydraulic
Ingabe indawo yokusebenza yama-hydraulic seals ayiwuketshezi noma igesi?Uma iwuketshezi, ukuhambisana phakathi koketshezi nezinto ezibonakalayo kufanele kucatshangelwe;Igesi nayo idinga ukucabangela ukuhambisana kwezinto ezinamafutha kanye namafutha;Ukuvalwa kwegesi kanye ne-negative pressure kufanele futhi kunake ukuphefumula.Uma into yokuvala ihambisana noketshezi oluvalayo, ingabangela i-elementi yokuvala ukuthi inwebe noma ifinyeze, okuholela ekuhlulekeni ezigabeni zokuqala zokusetshenziswa.Ukunwetshwa kophawu kubangela ukwanda kokumelana nokungqubuzana futhi kubangela ukuthi uphawu luginqike.Ukuncipha kwesici sokuvala kungabangela ukwehla kokulayishwa kusengaphambili, ukwehla komthamo wesinxephezelo se-eccentricity, futhi ekugcineni kuholele ekuvuzeni.
2. Ukubekwa uphawu okunamandla noma okumile
Ama-Dynamic seal anezidingo ezihambisanayo zokushayisana nokugqokwa kokusebenza kwezinto, futhi izinto ezisetshenziswayo ezinama-coefficients afanele wokungqubuzana kufanele zikhethwe ngokusekelwe kusayizi wesivinini sokunyakaza.Ukuze kuzuzwe impilo yesevisi eyanele, kuyadingeka futhi ukukhetha ukumelana nokugqoka kwezinto ezisekelwe esivinini kanye nokushaywa kokunyakaza.Uma kunesidingo sokusebenza kwesivinini esiphansi, ukunakwa okukhethekile kufanele kukhokhwe kusayizi we-coefficient yokungqubuzana kokubalulekile kanye nomehluko phakathi kwama-coefficients ashukumisayo kanye nama-static friction.
3. Uhlobo lwesakhiwo sesici sokuvala (esikhishiwe noma esimise udebe)
Isimiso sokusebenza sokubeka uphawu siyahlukahluka ngezinhlobo ezahlukene zesakhiwo, okudinga ngokungenakugwenywa izici zemishini ezihlukene njengokunwebeka, amandla, kanye nezinga lokuwohloka kwezinto.
4. Izinga lokushisa elisebenzayo lama-hydraulic seal
Izinga lokushisa elisebenzayo lamarabha okuvala uphawu namapulasitiki ahluka kakhulu.Lapho ukhetha izinto zokwakha, kuyadingeka ukubamba ngokunembile izinga lokushisa lokusebenza kwezingxenye zokubeka uphawu, ikakhulukazi indawo yokushisa ephansi lapho izingxenye zitholakala khona, futhi ukhethe izinto ngokufanele;Noma lawula ukukhuphuka kwezinga lokushisa kwezingxenye, amasistimu, nezigxivizo ngokusekelwe ebangeni lokushisa elisebenzayo lezinto.Khetha izinto ezikwazi ukumelana nezinga lokushisa eliphezulu kakhulu.
- Ukucindezela kokusebenza kwezimpawu ze-hydraulic
Ingcindezi yokusebenza iyipharamitha eyinhloko yokusebenza yezinhlelo ezisebenza ngogesi kanye ne-pneumatic, ezingahluka phakathi kuka-1-400MPa noma ububanzi obukhulu.Ukumelana nokucindezela kwezinto ezibonakalayo kufanele kuhambisane nezidingo zokucindezela kokusebenza.
6. Ingabe indawo yokusebenza ye-hydraulic seals ingcolile Izimo, okokusebenza kufanele kube nokunwebeka okwanele ukunxephezela ukucindezela okunganele kokuxhumana okubangelwa ukugudluka okubangelwa ukudlidliza.
