Izikulufu zokubopha zidlala indima ebalulekile ezimbonini nasezinsizeni ezahlukahlukene, zihlinzeka ngendlela ethembekile nephumelelayo yokuhlanganisa izinto.
1. Ukubaluleka kwezikulufu:
Izikulufu zibalulekile cishe kuyo yonke imboni, kusukela kwezokwakha kanye nezimoto kuya kugesi nefenisha. Lezi zibopheli eziguquguqukayo zinikeza ukuxhumana okuqinile, okuqinisekisa ukuzinza nobuqotho bezingxenye ezihlanganisiwe. Ngokuqinisa ngokuvikelekile izinto ezingafani, izikulufu zidala imikhiqizo esebenzayo nehlala isikhathi eside.
2. Inqubo yokukhiqiza izikulufu:
Ukukhiqizwa kwe-screw fasteners kuhilela izinyathelo ezimbalwa eziyisisekelo, ezihlanganisa:
a) Ukukhetha impahla:
Abakhiqizi bakhetha ngokucophelela okokusebenza kwesikulufa esifanele, becabangela izici ezifana namandla, ukumelana nokugqwala, nokufaneleka kwendawo ethile. Izinto ezijwayelekile zifaka insimbi engagqwali, i-carbon steel, i-aluminium, nethusi.
b) Ukukhiqizwa kwezintambo:
Impahla ekhethiwe yenziwa intambo ngezinqubo ezifana nokuginqika okushisayo noma umdwebo obandayo. Lesi sinyathelo siqinisekisa ukuthi izikhala zezikulufo ezingaguquki, ezisezingeni eliphezulu ziyakhiqizwa.
c) Ubude:
Intambo engenalutho iyasikwa ibe ngobude obufunekayo bese ifojwa emshinini wesihloko. Le nqubo ibumba ikhanda lesikulufu futhi ililungisela ukukhohlisa okulandelayo.
d) Ukucutshungulwa kochungechunge:
Ukucupha kuhlanganisa ukudala i-helical groove ku-screw shaft eyivumela ukuthi ingene futhi ibandakanye ingxenye ehambisanayo. Lokhu kungafezwa ngezindlela ezinjengokugoqa intambo, ukusika intambo noma ukwenza intambo.
e) Ukwelashwa kokushisa nokunamathiswa:
Ukuze kuthuthukiswe izakhiwo zemishini nokumelana nokugqwala, izikulufu zivame ukuba ngaphansi kwezinqubo zokwelashwa kokushisa ezifana nokudonsa, ukucisha, kanye nokushisa. Ngaphezu kwalokho, izimbotshana ezinjengama-galvanized, galvanized or organic coatings zisetshenziselwa ukuhlinzeka ngokuvikela ukugqwala okwengeziwe.
f) Ukuhlola nokupakisha:
Ngaphambi kokupakishwa, izikulufu zihlolwa ngokuqinile ikhwalithi ukuze kuqinisekiswe ukunemba kobukhulu, amandla kanye nokuqedwa kwendawo. Uma sezigunyaziwe, zipakishwa ngobuningi noma ngenani elithile, zilungele ukusatshalaliswa.

3. Isidingo semakethe sezikulufu:
Isidingo semakethe sezikulufu siyaqhubeka nokuba namandla ngenxa yezizathu ezilandelayo:
a) Ukukhula kwezimboni:
Njengoba izimboni ezifana nezokwakha, ezezimoto neze-elekthronikhi zikhula emhlabeni wonke, isidingo sezixazululo ezithembekile nezisebenzayo zokubopha senyuke kakhulu. Izikulufu zinikeza izinketho ezihlukahlukene nezingenziwa ngendlela oyifisayo ukuhlangabezana nalezi zidingo kuzo zonke izimboni.
b) Ukulungisa nokunakekela:
Njengoba ingqalasizinda ekhona kanye nezinto zokusebenza zidinga ukulungiswa noma ukuthuthukiswa, isidingo sezikulufu siba bucayi. Izinto zokubopha zidlala indima ebalulekile ekunakekeleni nasekuphileni isikhathi eside kwemishini, ziqinisekisa ukusebenza kahle futhi zinqande isikhathi sokuphumula esibizayo.
Fingqa:
Inqubo yokukhiqiza izinsimbi zokubopha ngezikulufo ibandakanya ukunaka ngokucophelela ekukhetheni impahla, ukwenziwa kanye nokuqedwa. Izikulufu zidlala indima ebalulekile ekuhlinzekeni ukuxhumana okuphephile nokufeza izidingo zezimboni ezahlukene futhi ngenxa yalokho zihlala zingumkhiqizo oyisisekelo ezinhlelweni eziningi.
