Lapho Ukhetha Ama-Gaskets Afanele Izicelo Eziqondile, Lezi Zici Ezibalulekile Ezilandelayo Zingacatshangelwa: | I-Hebei Wuyang Fastener Co., Ltd

Izinga lokushisa:

Khetha i-gasket ngokusekelwe emazingeni okushisa aphezulu kanye nobuncane bendawo yokusebenza, kanye nezinga lokushisa elivumelekile eliqhubekayo lokusebenza. Ibanga lokushisa elingamelana nezinto ezihlukene ze-gasket liyahlukahluka kakhulu. Isibonelo, amanye ama-gaskets angewona awensimbi angase afanele amazinga okushisa aphansi, kuyilapho ama-gaskets ensimbi ngokuvamile akwazi ukumelana namazinga okushisa aphezulu. Ngasikhathi sinye, izinto ze-gasket kufanele zibe nokumelana nokukhuphuka ukuze kuncishiswe ukuphumula kwengcindezi nokuqinisekisa ukubekwa uphawu ngaphansi kwezimo zokusebenza. Kungenziwa ireferensi eshadini eliphezulu lokushisa elisebenzayo lezinto ezisetshenziswa ngokuvamile ezingezona ezensimbi kanye nedatha yokuqhathanisa yokuhlolwa kwe-creep of gaskets ezingeni lokushisa elithile.

Isimo sohlelo lokusebenza:

Ulwazi oluqondile mayelana nesistimu yokuxhuma lapho i-gasket itholakala khona idinga ukucatshangelwa, njengempahla ye-flange, uhlobo nokuqina kwendawo yokuvala, kanye nesimo esifanele samabhawudi. Kuma-flange angewona awensimbi, kuyadingeka ukukhetha ama-gaskets anezidingo eziphansi zamandla okuqinisa amandla ukuvikela ukuthi i-flange ingachotshozwa ngesikhathi senqubo yokubopha; Izinhlobo ezahlukene zezindawo zokuvala i-flange zihambisana nezinhlobo ezahlukene zama-gaskets amanxeba; Futhi ama-gaskets ahlukene nawo anezidingo ezihlukene ze-flange roughness.

Izici ezimaphakathi:

I-gasket akufanele ithinteke umshini wokufaka uphawu ngaphansi kwazo zonke izimo zokusebenza, okufaka ukumelana nokushisa okuphezulu kwe-oxidation, ukumelana nokugqwala kwamakhemikhali, ukumelana ne-solvent, ukumelana nokuqina, njll. Ukumelana nokugqwala kwamakhemikhali kwempahla ye-gasket kuya phakathi ukucatshangelwa okuyinhloko. Okwezinto ezingezona ezensimbi kuma-gasket angewona ezensimbi noma ama-gasket ahlanganisiwe, ireferensi ingenziwa kuthebula lezinto ezingezona ezensimbi zokumelana namakhemikhali elinikezwe umkhiqizi we-gasket. Uma kukhona izinto zensimbi ezithintana ngokuqondile ne-medium ku-gasket, ukumelana kwayo nokugqwala akufanele kube ngaphansi noma kuphakeme kunalokho kwempahla ye-flange.

Ingcindezi:

I-gasket kumele ikwazi ukumelana nokucindezela okukhulu ohlelweni, okungase kube izikhathi ezingu-1.25-1.5 ingcindezi evamile yokusebenza. Kuma-gasket angewona awensimbi, kuyadingeka futhi ukuthi kubhekwe ukuthi umkhiqizo wezinga eliphezulu lokushisa lawo elisebenzayo kanye nokucindezela okukhulu (ivelu ye-PxT) ungaphakathi kwebanga elilinganiselwe, njengoba izinhlobo ezahlukene zama-gaskets zingamelana nezingcindezi ezihlukene. Ngaphezu kwalokho, kuyadingeka ukuhlola umdwebo wokulinganisa umfutho we-flange osebenza ezinhlotsheni ezahlukene zama-gaskets.

Usayizi:

Ngokwesisekelo sokuhlangabezana nobulukhuni nokungalingani kwe-flange, zama ukukhetha ama-gaskets amancane. Ubukhulu be-gasket buhlobene nezici ezifana nohlobo lwayo, impahla, ububanzi, isimo sokucubungula sendawo yokuvala, kanye nendawo yokuvala. Ngokuvamile, ama-gaskets azacile anamandla anamandla okumelana nokuphumula kwengcindezi, indawo encane lapho ethintana nendawo ephakathi nendawo, ukuvuza okuncishisiwe okuhambisana nomzimba we-gasket, namandla amancane okuphephuka, okuwenza mancane amathuba okuthi aqhunyiswe. Ubukhulu obufanele be-gasket nobunye ubukhulu kungabuye kukhethwe ngokusekelwe kumazinga afanele we-gasket.

Ngaphezu kwalokho, izici ezifana nezakhiwo zomzimba nezomshini, ukusebenza kwe-compression rebound, izinga lokuphumula kwengcindezi, kanye nezinga lokuvuza kwe-gasket kufanele kucatshangelwe. Ngesikhathi esifanayo, landela izindinganiso ezifanele zemboni kanye nokucaciswa kokuqinisekisa ukuthi ukukhethwa kwama-gaskets kuhlangabezana nezidingo zezicelo ezithile. Uma uhlelo lokusebenza lunezidingo ezikhethekile noma abekho osayizi abajwayelekile bokuxhumana, ukwakheka okukhethekile kungadingeka. Izinhlobo ezijwayelekile zama-gaskets zifaka ama-non-metallic gaskets, ama-semi metallic gaskets, nama-metallic gaskets. Izinhlobo ezahlukene zama-gaskets zinezici ezihlukene kanye nobubanzi obusebenzayo. Isibonelo, ama-gaskets angewona ezensimbi (njengamashidi eshidi lerabha le-asbestos, ama-gaskets ahlanganiswe ne-PTFE, njll.) avame ukusetshenziswa ezinhlelweni ezinomfutho ophansi; Ama-gaskets ensimbi ayisigamu (njengama-spiral amanxeba gaskets nama-gaskets anensimbi) anokuvalwa okuhle nokusebenza kokumelana nokucindezela; Ama-gaskets ensimbi afaneleka ezimweni zokucindezela okuphezulu, futhi izinto zabo zikhethwa ngokusekelwe ezintweni ezilimazayo kanye nezinga lokushisa eliphakathi.
