Iwaranti yomenzi wombhobho wentsimbi yoxinzelelo oluphezulu
Umbhobho wentsimbi onyanisekileyo woxinzelelo oluphezulu lwefektri enkulu unomgangatho ophezulu kunye nexabiso eliphantsi.
Umbhobho wentsimbi yoxinzelelo oluphezulu yintsimbi yekhabhoni ephezulu, i-alloy structural iron kunye nentsimbi engenamthungo yombhobho osetyenziselwa ukwenza iinqanawa zoxinzelelo oluphezulu kunye nemibhobho.
Umbhobho wentsimbi woxinzelelo oluphezulu uneempawu ezilungileyo ezibanzi zoomatshini kwindawo yobushushu begumbi kunye nobushushu obuphezulu kunye nolawulo olungqongqo lwekhwalithi. Ifanelekile kwiimeko ezahlukeneyo zokusebenza phantsi koxinzelelo oluphezulu. Imibhobho yentsimbi yoxinzelelo oluphezulu isetyenziswa kakhulu kwimimandla yeebhoyili, imibhobho yeoli yoxinzelelo oluphezulu lweenjini zedizili, izixhobo zesichumisi sekhemikhali kunye nemibhobho.
Iimfuno zokufakelwa kwemibhobho yoxinzelelo oluphezulu zifana nezo zokufakelwa kwemibhobho ephakathi kunye nephantsi, kodwa iimfuno ziphezulu kwaye imimiselo inzima. Ngoko ke, ngaphezu kokuhlangabezana neemfuno zofakelo lwemibhobho ephakathi kunye nephantsi, ezi mfuno zilandelayo ziya kulandelwa.
Amacandelo ombhobho woxinzelelo oluphezulu, izixhobo zokufakelwa kombhobho, i-fasteners kunye neevalve ezisetyenziselwa ukufakela kufuneka zigqithise ukuhlolwa kwaye zifakwe kunye namaxwebhu axhasayo ahambelanayo. Emva kokuba zihanjiswe kwindawo, ziya kugcinwa ngokufanelekileyo, ziphawulwe kwaye zibekwe ngokucocekileyo. Phambi kofakelo, umphezulu wangaphakathi nangaphandle uya kucinywa, kwaye umjelo wangaphakathi uya kukhangelwa imiba yangaphandle kunye nokuguda. Jonga ukuba uburhabaxa bomphezulu wokutywina we-nozzle kunye ne-gasket iyahlangabezana neemfuno. Akusayi kubakho mikrwelo (ingakumbi imikrwelo ye-radial), amabala kunye nezinye iziphene ezichaphazela ukusebenza kokutywinwa kumphezulu wokutywina. Ngaphandle kwemibhobho eneemfuno zokuthoba, indawo yokuvala umlomo kunye negasket iya kugqunywa nge-oyile ye-injini okanye ibhotolo okanye ivaseline emhlophe yokukhusela. Inxalenye ephothiweyo yesiphelo sombhobho wombhobho ofanelekileyo woxinzelelo oluphezulu iya kugqunywa ngegrisi ye-molybdenum disulfide okanye i-oyile ye-graphite injini yokukhusela, ngaphandle kwemibhobho eyohliweyo njengoko ichaziwe.
Ngethuba lokufakela umbhobho, umbhobho osemthethweni uya kusetyenziselwa ukulungiswa, kwaye i-casing yokukhusela iya kufakwa kwi-pipe rack edibeneyo kunye nemibhobho yoxinzelelo oluphezulu kunye nokufakelwa ngokweemfuno zokuyila. Xa ufaka i-flange yoxinzelelo oluphezulu, i-chamfer yentambo yokuphela kombhobho iya kubonakaliswa. Xa ufaka i-gasket yokutywina, musa ukuyixhoma ngocingo lwetsimbi. Igrisi iya kufakwa kwi-orifice yombhobho kunye ne-gasket kwangaphambili, kwaye i-gasket yesinyithi ethambileyo yoxinzelelo oluphezulu iya kufakwa ngokuchanekileyo kwisitulo sokutywina. Iibholithi zeflange ziya kuqiniswa ngokulinganayo kwaye ngokulinganayo ngaphandle kokugqithisa. Emva kokuba iibholiti ziqiniswe, iiflange ezimbini ziya kuhambelana kwaye zigxininise. Imisonto evezwe ngaphandle kwamandongomane iya kuba yi-2 ~ 3 imisonto, ubuncinci imisonto emi-2, kwaye ubude obuveziweyo bebholiti nganye buya kufana ngokwesiseko. Ngexesha lofakelo, akuvumelekanga ukuhlawulela iimpazamo zokuvelisa okanye zokufakela ngokutsalwa okuqinileyo, ukutyhala, ukuguqula okanye ukuguqula ubukhulu be-gasket yokutywina. Ukuba ukufakwa kombhobho akukwazi ukuqhutyelwa kwaye kugqitywe ngokuqhubekayo, i-orifice yombhobho evulekile iya kuvalwa ngexesha. Iinxalenye zenxalenye yesampulu yesixhobo kumbhobho ziya kufakwa ngexesha elifanayo nombhobho. ilizwi
