E tlameha ho baloa bakeng sa ts'ebetso ea tšepe ea sheet: Mokhoa oa ho khetha li-screws tse itšebetsang? Tsebo e sebetsang ea ho qoba ho peperana le ho hlobola

Ts'ebetsong ea tšepe ea lakane, li-screws tse itšebetsang ke e 'ngoe ea li-fasteners tse sebelisoang hangata, empa khetho e fosahetseng e ka baka ho phatloha, ho hlobola, ho lokoloha le mathata a mang, a ama matla a sehlahisoa le katleho ea kopano. U ka khetha li-screws tse loketseng joang ho ipapisitse le botenya ba thepa, litlhoko tsa mojaro le maemo a tikoloho? Sengoliloeng sena se tla arolelana lintlha tsa bohlokoa tsa khetho le malebela a khahlanong le ho hloleha ho u thusa ho ntlafatsa litharollo tsa ho tiisa tšepe.

1.Lintlha Tse 'Nè Tsa Bohlokoa Khethong ea Sekheo sa ho Ithuta

Letlapa la tšepe le boima

Limetale tse fapaneng (joalo ka lipoleiti tsa tšepe tse kolobisitsoeng ka serame, tšepe e sa jeleng paate, le lipoleiti tsa aluminium) li na le phapang e kholo ea ho thatafala, e amang ka kotloloho bokhoni ba ho kenella ba likurufu tsa ho itahlela:

Lisebelisoa tse bonolo (aluminium, koporo):e loketseng bakeng sa li-screws tsa khoele e ntle ho fokotsa kotsi ea ho senyeha ha lintho.

Lisebelisoa tse thata (tšepe e sa hloekang, lipoleiti tse teteaneng tsa tšepe):likhoele tse mahoashe kapa mehatla ea ho phunya (li-screws tsa TEK) lia hlokahala ho etsa bonnete ba ho kenella ka boreleli.

Botenya ba poleiti bo tsamaellanang le bolelele ba sekoti

Bolelele ba Screw = botenya ba poleiti + makhetlo a 2 ~ 3 ho feta sekontiri (ho etsa bonnete ba ho kopanela ka ho feletseng le ho qoba ho hlobola).

Khutšoane haholo:khoele e sa lekaneng, e bonolo ho e lokolla; nako e telele haholo: e ka phunyeletsa kapa ya sitisa sebopeho sa ka hare.

Mofuta oa hlooho le mokhoa oa ho kopanya

Hlooho ea pan / hlooho ea countersunk:se sebedisoang dibakeng tse nang le ditlhoko tse hodimo bakeng sa sephara sa bokahodimo.

Hlooho ea hexagonal/hlooho ea flange:e fana ka torque e phahameng le phello e ntle ea anti-loosening.

Mohatla o ikatisang (TEK):e loketse lipoleiti tse teteaneng, ha ho na ho cheka pele, le ho ntlafatsa bokhoni.

Phekolo ea holim'a metsi le ho ikamahanya le maemo a tikoloho

Setifikeiti:ka kakaretso anti-rust, e loketseng maemo a ka hare.

Dacromet / tšepe e sa hloekang:e thibelang ho bola, e loketseng tikoloho ea kantle kapa e mongobo.

2. Tsebo tse tharo tse sebetsang tsa ho qoba ho petsoha le ho hlobola

Ntlafatso ea pele ho cheka (bakeng sa lisebelisoa tse thata haholo)

Ka lipoleiti tsa tšepe tse sa hloekang kapa tse teteaneng, u ka qala pele ho phunya lesoba la sefofane (sekoti sa lesoba bophara ≈ 70% ea bophara ba "screw core diameter" ho fokotsa ho hanyetsa ho kenella le ho fokotsa kotsi ea ho phunyeha.

Laola ho tiisa torque

Torque e feteletseng:e bakang deformation kapa khoele e thellang.

Torque e sa lekaneng:tebeletsano e hlephileng le ho hlephisa ho bonolo.

Ho khothalletsoa ho sebelisa screwdriver ea torque, e buang ka boleng bo tloaelehileng bo fanoeng ke moetsi.

Khetha moralo o thibelang ho lokoloha

Ka li-washer tsa nylon:eketsa khohlano le ho thibela ho sisinyeha ho hlephisa.

Moralo oa likhoele tse peli:ntlafatsa matla a meshing, a loketseng maemo a boima a boima.

3. Lipotso tse atisang ho botsoa (Q&A)

P: Li-screws tse itšebetsang li bonolo ho thella holim'a lipoleiti tse tšesaane. Joang ho e rarolla?

K: Sebelisa li-screws tsa khoele e ntle kapa li-screws tse itšebetsang tse nang le mahlakore a sehang ho ntlafatsa matla a ho loma ha khoele.

P: Li-screws tse tloaelehileng tsa ho itšebetsa li bonolo ho pshatla holim'a lipoleiti tsa tšepe tse sa hloekang. Ke etseng?

A: Khetha likurufu tsa tšepe tse 304 kapa tse 316 le likoti tse nyane pele u phunya ho fokotsa khatello ea maikutlo.

P: Ho qhaqhoa khafetsa le kopano ho lebisa ho hloleheng ha khoele. Mekhoa e meng ke efe?

A: Sebelisa linate tsa rivet (Rivnut) kapa matsoho a khoele ho matlafatsa nako e telele.

Kakaretso

Khetho ea li-screws tse itšebetsang e hloka ho nahana ka botlalo ka thepa, botenya ba poleiti, mojaro le tikoloho, ho lumellana ka mokhoa o utloahalang le mofuta oa hlooho le phekolo ea bokaholimo, le ho laola mokhoa oa ho tiisa ho qoba mathata a kang ho petsoha le ho hlobola. Bakeng sa maemo a khethehileng a ts'ebetso (joalo ka ho sisinyeha ho phahameng le tikoloho e senyang), mefuta e thibelang ho lokoloha kapa e thibelang kutu e ka khethoa, kapa ea kopanngoa le theknoloji ea ho cheka pele le ho matlafatsa likhoele ho ntlafatsa tharollo.
