Izikhonkwane zezikrufu zidlala indima ebalulekileyo kumashishini ahlukeneyo kunye nokusetyenziswa kwazo, zibonelela ngendlela ethembekileyo nesebenzayo yokudibanisa izinto.
1. Ukubaluleka kwezikrufu:
Izikrufu zibalulekile phantse kuyo yonke imboni, ukusuka kwezokwakha nakwiimoto ukuya kwizixhobo ze-elektroniki kunye nefenitshala. Ezi zikrufu zisebenza ngeendlela ezahlukeneyo zibonelela ngonxibelelwano oluqinileyo, ziqinisekisa uzinzo kunye nokuthembeka kwezinto ezidibeneyo. Ngokubopha ngokukhuselekileyo izinto ezahlukeneyo, izikrufu zenza iimveliso ezisebenzayo nezihlala ixesha elide.
2. Inkqubo yokuvelisa izikrufu:
Ukuveliswa kwezikhonkwane ze-screw kubandakanya amanyathelo aliqela asisiseko, kuquka:
a) Ukukhetha izinto:
Abavelisi bakhetha ngononophelo izinto ezifanelekileyo zezikrufu, bethathela ingqalelo izinto ezinje ngamandla, ukumelana nokugqwala, kunye nokufaneleka kwindawo ethile. Izinto eziqhelekileyo ziquka intsimbi engatyiwayo, intsimbi yekhabhoni, i-aluminium, kunye nobhedu.
b) Imveliso yentambo:
Izinto ezikhethiweyo zenziwa ucingo ngeenkqubo ezifana nokuqengqeleka okushushu okanye ukutsalwa okubandayo. Eli nyathelo liqinisekisa ukuba kuvela izikrufu ezingabonakaliyo nezisemgangathweni ophezulu.
c) Ubude:
Intambo engenanto iyasikwa ibe nobude obufunekayo ize ihlanganiswe kumatshini wokulungisa intloko. Le nkqubo ibumba intloko yesikrufu kwaye iyilungiselela ukulungiswa okulandelayo.
d) Ukulungiswa kwemisonto:
Ukuxovula umsonto kubandakanya ukudala umngxuma ojikelezayo kwi-screw shaft evumela ukuba ingene kwaye ibandakanye icandelo elifanelekileyo. Oku kunokufezwa ngeendlela ezinje ngokuxovula umsonto, ukusika umsonto okanye ukwenza umsonto.
e) Unyango lobushushu kunye nokwaleka:
Ukuze komelezwe iipropati zoomatshini kunye nokumelana nokugqwala, izikrufu zihlala zisetyenziswa kwiinkqubo zonyango lobushushu ezifana nokuqhoboshela, ukucima, kunye nokuthambisa. Ukongeza, izinto zokugquma ezifana ne-galvanized, galvanized okanye i-organic coatings zisetyenziselwa ukubonelela ngokhuseleko olongezelelekileyo lokugqwala.
f) Ukuhlolwa kunye nokupakisha:
Ngaphambi kokupakishwa, izikrufu zihlolwa ngononophelo lomgangatho ukuqinisekisa ukuchaneka kobukhulu, amandla kunye nokugqitywa komphezulu. Nje ukuba zivunyiwe, ziyapakishwa ngobuninzi okanye ngobuninzi obuthile, zilungele ukusasazwa.

3. Imfuno yemarike yezikrufu:
Imfuno yemarike yezikrufu iyaqhubeka nokuba namandla ngenxa yezi zizathu zilandelayo:
a) Ukukhula kwemizi-mveliso:
Njengoko amashishini afana nokwakha, iimoto kunye ne-elektroniki esanda kwihlabathi liphela, imfuneko yezisombululo zokubopha ezithembekileyo nezisebenzayo iyanda kakhulu. Izikrufu zibonelela ngeendlela ezahlukeneyo kunye neendlela ezinokwenziwa ngokwezifiso ukuhlangabezana nezi mfuno kumashishini onke.
b) Ukulungiswa kunye nokugcinwa:
Njengoko iziseko zophuhliso nezixhobo ezikhoyo zifuna ukulungiswa okanye ukuphuculwa, imfuneko yezikrufu iba yinto ebalulekileyo. Izibophelelo zidlala indima ebalulekileyo ekugcinweni nasekuhlaleni ixesha elide koomatshini, ziqinisekisa ukusebenza kakuhle kwaye zithintela ukungasebenzi okubizayo.
Shwankathela:
Inkqubo yokwenziwa kweziqhoboshi zezikrufu ibandakanya ingqalelo enzulu ekukhetheni izinto, ukwenziwa kwazo kunye nokugqitywa kwazo. Izikrufu zidlala indima ebalulekileyo ekuboneleleni ngonxibelelwano olukhuselekileyo kunye nokuzalisekisa iimfuno zamashishini ahlukeneyo kwaye ngenxa yoko zihlala ziyimveliso ebalulekileyo kwizicelo ezininzi.
