Iwaranti yomkhiqizi wepayipi lensimbi enomfutho ophezulu
Ipayipi lensimbi elinomfutho ophezulu wangempela wefekthri enkulu lisezingeni eliphezulu futhi linenani eliphansi.
Ipayipi lensimbi elinomfutho ophezulu yinsimbi yekhwalithi ephezulu, insimbi yensimbi eyingxubevange kanye nepayipi lensimbi engenamthungo elisetshenziselwa ukwakha imikhumbi namapayipi anengcindezi ephezulu.
Ipayipi lensimbi elinomfutho ophakeme linezici ezinhle eziphelele zemishini ekamelweni lokushisa kanye nezinga lokushisa eliphezulu kanye nokulawulwa kwekhwalithi okuqinile. Ifanele izikhathi ezihlukahlukene zokusebenza ngaphansi kwengcindezi ephezulu. Amapayipi ensimbi anomfutho ophakeme asetshenziswa kakhulu emkhakheni wamaboilers, amapayipi kawoyela anomfutho ophezulu wezinjini zikadizili, imishini kamanyolo wamakhemikhali namapayipi.
Izidingo zokufakwa kwamapayipi anengcindezi ephezulu zifana nalezo zokufakwa kwamapayipi aphakathi nendawo naphansi, kodwa izidingo ziphakeme futhi imithethonqubo iqinile. Ngakho-ke, ngaphezu kokuhlangabezana nezidingo zokufakwa kwamapayipi aphakathi nendawo naphansi, lezi zidingo ezilandelayo zizolandelwa.
Izingxenye zamapayipi anomfutho ophezulu, izifakelo zamapayipi, izinsimbi nama-valve asetshenziselwa ukufakwa kumele kudlule ukuhlolwa futhi kuhlanganiswe nemibhalo ehambisanayo esekela ubuchwepheshe. Ngemuva kokuthi zihanjiswe endaweni, zizogcinwa kahle, zimakwe futhi zibekwe ngobunono. Ngaphambi kokufakwa, izindawo zangaphakathi nezingaphandle zizosulwa zihlanzeke, futhi umgudu wangaphakathi uzobhekwa ukuthi awunazo yini izindaba zangaphandle kanye nokushelela. Hlola ukuthi ubumahhadlahhadla bendawo yokuvala umlomo wombhobho kanye ne-gasket iyahlangabezana yini nezidingo. Akumele kube khona imihuzuko (ikakhulukazi imihuzuko yama-radial), amabala nokunye ukonakala okuthinta ukusebenza kokuvala endaweni yokuvala. Ngaphandle kwamapayipi anezidingo zokwehlisa amafutha, indawo yokuvala umlomo wombhobho kanye ne-gasket kufanele igcotshwe ngamafutha enjini noma ibhotela noma uvaseline omhlophe ukuze uvikeleke. Ingxenye enentambo yokuphela kwepayipi yepayipi elifaneleka kakhulu lokucindezela kufanele igcotshwe ngamafutha e-molybdenum disulfide noma uwoyela wenjini yegraphite ukuze ivikeleke, ngaphandle kwamapayipi ancishisiwe njengoba kucacisiwe.
Ngesikhathi sokufakwa kwamapayipi, indawo yokubeka ipayipi ehlelekile izosetshenziselwa ukulungiswa, futhi i-casing yokuzivikela izofakwa endaweni yokubeka ipayipi ngokuthintana namapayipi okucindezela okuphezulu kanye nokufakwa ngokuvumelana nezidingo zokuklama. Lapho ufaka i-flange yokucindezela okuphezulu, i-chamfer yentambo yokuphela kwepayipi izodalulwa. Lapho ufaka i-gasket yokuvala, ungayilengi ngocingo lwensimbi. Ugrisi uzofakwa embotsheni yepayipi kanye ne-gasket kusengaphambili, futhi i-gasket yensimbi ethambile enomfutho ophezulu izofakwa ngokunembile esihlalweni sokuvala. Amabhawodi e-flange kufanele aqiniswe ngokulinganayo nangokulinganayo ngaphandle kokweqisa. Ngemuva kokuthi ama-bolts eqinisiwe, ama-flange amabili azobe ehambisana futhi agxile. Imicu eveziwe ngaphandle kwamantongomane izoba yizintambo ezingu-2 ~ 3, okungenani imicu emi-2, futhi ubude obuveziwe bebhawodi ngalinye buzofana ngokuyisisekelo. Ngesikhathi sokufakwa, akuvunyelwe ukunxephezela amaphutha okukhiqiza noma okufaka ngokudonsa okuqinile, ukusunduza, ukusonta noma ukuguqula ubukhulu be-gasket yokuvala. Uma ukufakwa kwepayipi kungenakukwazi ukwenziwa futhi kuqedwe ngokuqhubekayo, i-orifice yepayipi evulekile izovalwa ngesikhathi. Izingxenye zengxenye yesampula yethuluzi epayipini zizofakwa ngesikhathi esifanayo nepayipi. izwi
