Kunezinhlobo ezimbili zamapayipi ensimbi angenamthungo, i-hot-dip galvanizing (i-hot-dip galvanizing) kanye ne-cold-dip galvanizing (i-electro-galvanizing).I-hot-dip galvanizing inongqimba oluqinile olunothayela, olunobuhle bokunamathisa okufanayo, ukunamathela okuqinile, nempilo ende yesevisi.Kodwa-ke, izindleko ze-electro-galvanizing ziphansi, indawo engaphezulu ayibushelelezi kakhulu, futhi ukumelana kwayo nokugqwala kubi kakhulu kunamapayipi afaka amapayipi ashisayo.Indlela yokuhlola ikhwalithi yamapayipi ensimbi engenamthungo?

Ngokwezidingo zaleli zinga, umkhiqizi wamapayipi anothayela waveza ukuthi ukuhlolwa kobukhulu be-geometric bepayipi elingenamthungo ikakhulukazi kuhlanganisa ukushuba kodonga, ububanzi bangaphandle, ubude, ukugoba, ukuqanda kanye nokuma kokuphela kwepayipi elingenamthungo.

1. Ukuhlolwa kokuqina kwezindonga

Ithuluzi elisetshenziselwa ukuhlola ukujiya kodonga ngokuyinhloko i-micrometer.Uma uhlola, linganisa ubukhulu bodonga lwepayipi likathayela ngamunye ngamunye nge-micrometer.Ngaphambi kokuhlolwa, qala ngokuqinisekisa ukuthi isitifiketi se-micrometer singaphakathi kwesikhathi sokuqinisekisa, futhi uhlole ukuthi i-micrometer ihambisana nendawo eyiziro nokuthi ukuzungezisa kuyavumelana yini.Indawo yokulinganisa kufanele ingabi nemihuzuko namabala okugqwala, futhi ingasetshenziswa kuphela ngemva kokuphumelela ukuhlolwa.Uma uhlola, bamba ibakaki le-micrometer ngesandla sobunxele bese uzungezisa isondo elivusa amadlingozi ngesandla sokudla.I-screw rod kufanele ihambisane nobubanzi bephoyinti lokulinganisa, futhi ukulinganisa kwendawo yokugcina kufanele kungabi ngaphansi kwamaphoyinti angu-6.Uma ukushuba kodonga kutholakala ukuthi akufanelekile, kufanele kumakwe.

2. Ububanzi bangaphandle nokuhlolwa kwe-ovality

Amathuluzi asetshenziselwa ukuhlola ububanzi bangaphandle kanye ne-ovality ikakhulukazi ama-caliper nama-vernier caliper.Ngesikhathi sokuhlola, linganisa ububanzi bangaphandle bepayipi eliyisithako ngasinye nge-caliper efanelekayo.Ngaphambi kokuhlolwa, qala ngokuqinisekisa ukuthi isitifiketi se-caliper singaphakathi kwesikhathi sokufaneleka, futhi uhlole ikhalipha esetshenzisiwe nge-vernier caliper ukuze ubone ukuthi akukho yini ukuklwebheka noma ukugqwala endaweni yokulinganisa, futhi singasetshenziswa kuphela ngemva kokudlula test.Ngesikhathi sokuhlolwa, i-caliper kufanele ibe yi-perpendicular ku-axis yepayipi ye-galvanized, futhi ipayipi elihlanganisiwe lijikeleza kancane.Uma ububanzi obungaphandle besigaba lapho isilinganiso senziwa khona sitholakala sikhulu kakhulu noma sincane kakhulu, kufanele simakwe.

3. Ukuhlola ubude

Ithuluzi elisetshenziselwa ukuhlola ubude bepayipi elingenamthungo elifakwe uthayela liyi-tape yensimbi.Lapho ulinganisa ubude, iphuzu elithi "O" le-tape lihambisana nomkhawulo owodwa wepayipi le-galvanized, bese i-tape iqiniswa ukuze uhlangothi lwesikali lwe-tape lusondele ebusweni bombhobho we-galvanized.Ubude be-tape komunye umkhawulo wepayipi likathayela ubude bepayipi likathayela.

4. Ukuhlolwa kokugoba kwepayipi likathayela

Ukuhlolwa kwezinga lokugoba lepayipi elithathiwe ngokuyinhloko ukuhlola izinga lokugoba lobude obuphelele bepayipi likathayela kanye nezinga lokugoba imitha ngalinye.Amathuluzi asetshenziswayo ikakhulukazi irula yeleveli, igeji yokuzizwa kanye nentambo yokudoba.Lapho ukala ingqikithi yokugoba idigri yepayipi elinothayela, sebenzisa intambo yokudoba ukuze uqondanise umkhawulo owodwa wepayipi lesikwele elinothayela, bese uqinisa intambo yokudoba ukuze uhlangothi olulodwa lwentambo yokudoba lusondele ebusweni bepayipi likathayela, bese emva kwalokho uqinise intambo yokudoba ukuze uhlangothi olulodwa lwentambo yokudoba lusondele ebusweni bepayipi likathayela. sebenzisa i-feeler gauge ukukala indawo engaphezulu yepayipi likathayela kanye nenhlanzi.Isikhala segebe lomugqa, okungukuthi, ubude obuphelele bepayipi elingenamthungo elinothayela.

Amacebiso: Uthayela kusho ukuthi ingaphezulu lepayipi lensimbi lifakwe uthayela, futhi kungaba yipayipi elishiselwe noma ipayipi elingenamthungo.Amanye amapayipi ensimbi ashiselwe enziwe ngokugingqika ngokuqondile kwamashidi, kanti amanye enziwe ngamapayipi ensimbi angenamthungo abese efakwa uthayela.
