Litaba tsa Palo ea Khoele: Kamoo Screw Threads Amang Kateng Ho Tšoara Matla

Ke Eng E Balloang Khoele ho Li-Screw?

Palo ea likhoele e bolela palo ea likhoele ka inch (TPI) holim'a screw. Litsamaisong tsa metric, e ka bitsoa pitch (sebaka se pakeng tsa likhoele). Apalo e phahameng ea likhoeleho bolela hore likhoele tse ngata li phuthetsoe haufi-ufi, ha apalo e tlase ea khoelee bonts'a likhoele tse fokolang, tse mahoashe.

Hangata li-screw li arotsoe ka lihlophae khoele e ntlekapae khoele e mahoashe, e 'ngoe le e' ngoe e na le melemo e ikhethang ho latela ts'ebeliso.

Fine vs Coarse Threads: Phapano ke Efe?

• Li-Screws tsa Khoele e Ntle
  Likhoele tse ntle li fana ka matla a betere ka lebaka la bophara bo bonyenyane bo boholo. Ha li ratehe ho thothomela, e leng se etsang hore e be tse loketseng lisebelisoa tse nepahetseng, likopano tsa likoloi, kapa ho tiisa tšepe ho isa ho tšepe moo ho tsamaisana ho leng bohlokoa. Leha ho le joalo, li kotsing ea ho hlobolisoa ka thepa e bonolo.

• Li-Screws tsa Khoele e Mahoashe
  Likhoele tse mahoashe li molemo bakeng sa ho kopanya kapele le ho tšoarela ho feta ho sebetsana ka thata. Li fana ka mokhoa o phahameng oa ho tšoara lehong, li-drywall le polasetiki, e leng se etsang hore e be tse loketseng bakeng sa kaho le ho tiisa ka kakaretso. Moralo oa bona o lumella ho khanna ka potlako le ts'ebetso e ntlafetseng ea thepa e atisang ho phunyeha kapa ho atoloha.

Kamoo Khoele Count e Amang Ho Tšoara Matla

Thetshoara matlaof a screw e bolela bokhoni ba eona ba ho hanela ho hula le ho boloka bots'epehi ba sebopeho ka nako. Mona ke kamoo palo ea likhoele e susumetsang seo:

• Ka Lisebelisoa tse Bonolo (mohlala, lehong, li-drywall):
  Likhoele tse mahoashe li cheka ho teba le ho tlosa lintho tse ngata, tse eketsang khohlano le ho ntlafatsa ho hanyetsa ho hula. Palo e tlase ea likhoele hangata e betere maemong ana.

• Linthong tse thata (mohlala, tšepe, aluminium):
  Likhoele tse ntle li fana ka ho kopana ho feta holim'a khoele ea ka hare ea thepa, ho aba mojaro ho pholletsa le lintlha tse ling tsa ho kopana. Sena se molemo bakeng sa ho tiisa tšepe-to-metal, moo matla le ho hanyetsa ho lokoloha ho leng bohlokoa.

• Ka Lisebelisoa tse Thin kapa Metal ea Sheet:
  Palo e phahameng ea khoele e ka thibela ho hlobola ka ho fokotsa monyetla oa ho kopana ha khoele kapa ho hloleha ka botebo bo fokolang ba thepa.

Ho Bapisa Khoele ea Khoele le Tšebeliso

Ho etsa bonnete ba ts'ebetso e nepahetseng, palo ea likhoele e lokela ho bapisoa le lisebelisoa le mosebetsi oa screw.

Eseng hakaalo. Ha likhoele tse ling li eketsa sebaka sa ho ikopanya, li ka boela tsa thehakhohlano e eketsehilengnakong ea ho kenya, ho hloka torque e phahameng. Ka lisebelisoa tse bonolo, sena se ka fokotsa matla a ho tšoara haeba thepa e qala ho kuta kapa ho hlobola.

Ka lehlakoreng le leng, likhoele tse fokolang (TPI e tlase) li ka fokotsa torque ea ho kenya le ho eketsa khanyetso ea ho tsoa libakeng tse ling tse kang phaene kapa drywall. Ntho ea bohlokoa ke ho nahanaboikopanyo ba khoele- hore na sekoti se "tšoara" thepa hantle hakae - ho fapana le ho nka hore ho feta ho molemo.
