Kopa li-screws tsa mohatla ke karolo ea bohlokoa indastering ea sejoale-joale 'me e sebelisoa haholo mafapheng a joalo ka boqapi, thepa ea ka tlung le lisebelisoa tsa motlakase. Leha ho le joalo, maemo a fapaneng a kopo a hloka mefuta e fapaneng le litlhaloso tsaho phunya dikurufu , kahoo ho khetha sekoti se nepahetseng sa ho cheka ho bohlokoa bakeng sa tlhahiso ea indasteri. Sengoliloeng sena se tla hlahisa mekhoa ea khetho ea li-screw tsa ho cheka ho thusa babali ho khetha le ho sebelisa li-screw tse loketseng.
1. Bokhoni ba ho jara moroalo
Bokhoni ba ho jara mojaro ke ntho e ka sehloohong eo ho nahanoang ka eona bakeng sa ho khetha ho chekalikurufu . Ha u khetha li-screws tsa mohatla oa ho phunya, ho hlokahala hore u khethe boholo bo loketseng le mofuta o ipapisitseng le boima le khatello ea maikutlo eo li e jereng. Hangata, matla a ho jara moroalo a amana le lintlha tse kang bophara, bolelele le thepa ea sekoti sa ho phunya. Tlas'a tikoloho le maemo a tšoanang, likurufu tsa mohatla tse teteaneng le tse telele li na le bokhoni bo betere ba ho jara.
2. Khetho ea lintho tse bonahalang
Thepa ea "drill tail screw" e na le tšusumetso e kholo ho thepa ea eona ea mochini le ho hanyetsa kutu. Lisebelisoa tse sebelisoang hangata bakeng sa li-screw tsa ho cheka li kenyelletsa tšepe,ts'epe e sa beng le mabali , joalo-joalo Ha u khetha li-screws tsa ho phunya, ho hlokahala hore u khethe boitsebiso bo loketseng ho latela boemo ba kopo. Ka mohlala, libakeng tse mongobo, ho hlokahala hore u khethe li-screws tse thibelang ho bola tsa tšepe ea tšepe ea ho cheka mohatla; Maemong a hlokang mocheso o phahameng oa ho hanyetsa, hoa hlokahala ho khetha li-screws tsa mohatla oa alloy tse nang le mocheso o motle oa ho hanyetsa.
3, boleng ba torque
Boleng ba torque ke e 'ngoe ea matšoao a bohlokoa a khethollang katleho ea li-screws tsa ho cheka. Ha u khetha sekoti sa mohatla oa ho phunya, hoa hlokahala ho bala boleng ba torque e hlokahalang ho latela maemo a nnete ho netefatsa hore sekoti sa mohatla oa ho cheka se ka kenngoa ka nepo le ka tieo. Haeba boleng ba torque bo le nyane haholo, bo ka etsa hore ho kengoa ha sekoti sa mohatla oa ho cheka ho se tsitse le ho lokoloha habonolo; Haeba boleng ba torque bo phahame haholo, bo ka senya lisekere kapa tsa baka mathata a ho kenya.
4. Corrosion resistance
Maemong a mangata a ts'ebeliso, li-screws tsa ho cheka li hloka ho kopana le lik'hemik'hale tse kang li-acids le alkalis, kahoo ho hanyetsa ha tsona ho hloka ho nahanoa. Ha u khetha li-screws tsa mohatla oa ho cheka, hoa hlokahala ho ela hloko ts'ebetso ea bona e khahlanong le kutu e le ho boloka botsitso le ts'epo ts'ebelisong ea nako e telele. Ka mohlala,ho phunya dikurufuka liphekolo tse holim'a metsi joalo ka zinki plating kapa chromium plating li ka khethoa ho ntlafatsa ho hanyetsa ha tsona.
5, Khetho ea lihlooho tsa drill mohatla
Ha u khetha drill mohatla screws, ho boetse ho hlokahala hore ho nahana ka boholo le sebōpeho sa drill mohatla screw hlooho. Lihlooho tse fapaneng tsa drill tail screw li loketse lisebelisoa tse fapaneng tsa ho cheka le ho kenya. Ka mohlala,dikurufu tsa hlooho tse bataletseng tsa mohatla li loketse ho cheka ka kakaretso le ho kenya; Li-screws tsa mohatla oa sefapano sa hlooho li loketse ho kenngoa ho sebelisa wrench e bōpehileng joaloka sefapano; Li-screws tsa mohatla oa hexagonal li loketse ho kenngoa ho sebelisoa li-wrenches tsa hexagonal. Ha u khetha li-drill tail screws, ho hlokahala hore u khethe hlooho e loketseng ea ho cheka mohatla ho latela litlhoko tsa sebele.
