Hlau - Nov yog ib qho ntawm cov khoom siv nrov tshaj plaws thiab nquag siv niaj hnub no. Nws tau pom dav siv tsis yog hauv kev lag luam hlau thiab ntau yam kev tsim khoom lag luam, tab sis tseem nyob hauv lub neej txhua hnub. Ntau yam qauv tsim thiab khoom tsim los ntawm nws. Thiab txhawm rau ua haujlwm nrog hlau, koj xav tau ntau yam cuab yeej tshwj xeeb thiab khoom siv.

Ib qho ntawm cov no yog cov ntsia hlau. Nws yog hais txog cov ntsia hlau rau cov hlau uas yuav tham txog hauv kab lus no - txog lawv cov yam ntxwv, yam thiab hom kev xaiv.

Peculiarities

Cov ntsia hlau yog cov ntsia hlau thiab raug suav tias yog hom ntsia hlau rau tus kheej . Cov ntsia hlau tsim yog qhov yooj yim heev. Nov yog pas nrig uas muaj ob ntu: ib qho yog ncaj, thiab xov tau txiav raws qhov ntev ntawm lwm qhov. Lub taub hau ntawm cov khoom yog semicircular, thiab qhov kawg yog ntse heev.

Txhua tus hlau ntsia hlau yog tus yam ntxwv hauv qab no:

• xov taub - los ntawm 1, 6 txog 10 hli;
• sab hauv txoj kab uas hla - los ntawm 1, 1 txog 7 hli;
• xov suab - ntawm 0.8 txog 4.5 hli;
• qhov dav ntawm qhov ncaj - ntawm 0.4 txog 2.5 hli;
• qhov loj ntawm tus ntoo khaub lig qhov yog 1-4 hli.

Screws yog ua raws li cov cai thiab txoj cai , uas tau muab rau hauv cov ntaub ntawv hauv xeev, uas yog: GOST 1144-80, GOST 1145-80, GOST 11473-75.

Screws rau hlau siv hauv kev sib dhos ntawm cov qauv hlau . Tias yog vim li cas lawv yuav tsum yog:

• ruaj;
• txhim khu kev qha;
• tsis txhob ntshai ntawm qhov cuam tshuam ntawm ntau yam tsis zoo;
• tiv taus hnav thiab rhuav;
• yooj yim thiab yooj yim rau nruab.

Nws yog ib qho tseem ceeb heev uas cov khoom no muaj lub neej ua haujlwm ntev . Txhawm rau ua tiav cov txheej txheem ntsuas no, tsuas yog cov khoom siv tau zoo hauv kev tsim cov khawm ris - carbon thiab stainless hlau, tooj dag … Tiav lawm cov khoom npog nrog cov khoom tshwj xeeb.

Hom kev txheeb xyuas

Qhov ntau ntawm cov ntsia hlau rau hlau, uas tam sim no tau nthuav tawm ntawm cov khw muag khoom, yog ntau dua thiab ntau yam sib txawv. Muaj ntau hom khoom:

• ntse dub - ntev ntawm 19 txog 152 hli, txheej sab nraud ntawm 3.5 txog 4.8 hli;
• nrog laum lossis, raws li nws tseem hu ua, tus kheej drilling - cov khoom ntev los ntawm 9, 5 txog 75 hli, txheej sab nraud ntawm 3, 5 txog 4, 2 hli;
• nrog lub tshuab ntxhua khaub ncaws - Cov khoom txuas nrawm yog qhov ntev los ntawm 13 txog 76 hli, txheej sab nraud ntawm 3, 5 txog 4, 2 hli.

Tus kheej tapping ntsia hlau kuj tseem yuav txawv ntawm nws lub hom phiaj. Muaj cov khoom lag luam rau cov ntawv hlau, rau cov ntawv hlau.

Cov khoom lag luam rau ntau hom hlau sib txawv hauv lub cev thiab kev ntsuas tsis zoo thiab cov yam ntxwv.

Tej zaum txhua tus neeg uas yuav tsum tau yuav cov ntsia hlau pom tias cov khoom lag luam tej zaum yuav txawv xim Nws nyob ntawm seb dab tsi txheej txheej txheej tau kho nrog.

• Dub - qhia tias qhov no yog phosphated lossis oxidized fastener. Cov khoom siv kho phosphate yog tsim rau siv sab hauv tsev nrog cov av noo siab. Tab sis cov khawm nrawm, uas siv cov yeeb yaj kiab tiv thaiv oxide, tuaj yeem siv hauv chav nrog qhov ntsuas cua ib txwm muaj.
• Galvanized - kho nrog zinc txheej. Nws yog cov ntsia hlau ntau yam uas tuaj yeem siv nrog hlau hauv ib puag ncig.
• Daj - raws li qhov ntsuas thiab cov khoom, lawv zoo ib yam rau galvanized.
• Khoom txho cov xim qhia tias cov ntsia hlau tsis tau kho nrog ib txheej tshwj xeeb. Cov khawm no tsuas yog haum rau siv sab hauv tsev.

Cov Lus Qhia Xaiv

Thaum xaiv cov ntsia hlau rau hlau, ob peb yam hauv paus ntsiab lus yuav tsum raug coj mus rau hauv tus account

1. Hom hlau twg koj yuav ua haujlwm nrog?
2. Cov txheej txheem tsis ntawm tus khawm ris - qhov loj me, xov xov, zoo ntawm lub taub hau thiab qhov kawg ntawm qhov kawg, ntev, tuab.
3. Xim - lub hauv paus yuav tsum yog xim ib yam nkaus.
4. Lub xub ntiag ntawm kev kos yog qhov yuav tsum tau ua ua ntej. Nws yog tus neeg ua tim khawv tias cov ntsia hlau tau ua raws li cov cai thiab cov cai. Cov cim muaj cov lej thiab cov ntawv Latin uas qhia tsis xws li qhov ntev, txoj kab uas hla thiab qhov hnyav ntawm cov khoom.

Zoo li xyuam xim rau hom khoom … Yuav tsum tsis muaj kev puas tsuaj lossis deformation ntawm cov ntsia hlau.

Nws yog qhov zoo tshaj los muab kev nyiam rau cov chaw tsim khoom uas paub zoo.
