Ukukhethwa kweSeal impahlas:
Okuvame ukusetshenziswa seal materialsenkampanini yethu kukhona Polyurethane, Nitrile iraba, Fluororubber, PTFE, njll, futhi izinto ezihlukahlukene zinezici ezahlukene, kanje:
(1) Impahla ye-polyurethane inokumelana okuhle nokugqokwa kanye nesilinganiso esincane sokuwohloka kokucindezelwa, futhi ngokuvamile isetshenziswa ezikhathini zokuvala ashukumisayo.Iyakwazi ukumelana nezinga lokushisa elisebenzayo lika -35-100 ℃, futhi ilungele uwoyela we-hydraulic osuselwa ku-petroleum.Ngaphandle kwezinto ezithunyelwa kwamanye amazwe, inokumelana ne-hydrolysis empofu futhi ayikwazi ukusetshenziselwa uwoyela we-hydraulic osuselwa emanzini, njenge-water glycol.
(2) Izinto zenjoloba ye-Nitrile azikwazi ukugqokwa kahle, futhi ngokuvamile zisetshenziswa ezindaweni zokuvala ezimile, noma zihlanganiswe nezinye izinto ezingagugi ukuze zenze izindandatho zokuvala ezinamandla, njengezindandatho ze-Glyd kanye nama-Step seal.Ingakwazi ukumelana nezinga lokushisa elisebenzayo lika -10-80 ℃, futhi inokuhambisana kahle namafutha ahlukahlukene wehydraulic ngaphandle kwe-phosphate ester.
(3) Impahla ye-fluororubber inokungagugi kahle kanye nekhono le-anti-extrusion.Ngokuvamile isetshenziswa ezindaweni zokuvala ezimile, noma ihlanganiswe nezinye izinto ezingagugi ukuze kwakheke indandatho yokuvala enamandla.Uma isetshenziselwa ukuvala okuguquguqukayo kukodwa, indandatho yesibambi kufanele yengezwe ukuvikela ukuphuma kwe-extrusion.Ingakwazi ukumelana nezinga lokushisa elisebenzayo lika -20-160 °C, futhi ingasebenza endaweni yokushisa ephezulu engu-200 °C isikhathi esifushane, futhi inokuhambisana kahle namafutha ahlukahlukene we-hydraulic.
(4) Izinto ze-PTFE zinokumelana okuhle kokugqoka kanye nekhono lokulwa ne-extrusion.Ngokuvamile isetshenziswa ngokuhambisana nezinto zenjoloba ukwenza uphawu oluguquguqukayo.Kodwa-ke, ngenxa yezinga layo elikhulu lokuwohloka kokucindezela, lingase libangele ukuvuza okukhulu lapho lisetshenziswa ngengcindezi ephansi.Ngokuvamile isetshenziswa endaweni yokushisa ephezulu ngaphezu kwama-25MPa.Ingakwazi ukumelana nezinga lokushisa elisebenzayo lika -40-135 ℃, futhi inokuhambisana okuhle namafutha ahlukahlukene we-hydraulic.
