Ukulungisa ngokuzenzekelayo isihlwele indlela yokukhetha isitshixo setorque

I-torque wrench sisixhobo esisetyenziswa ngokuqhelekileyo kwimisebenzi yokulungisa i-auto, enokuthi ihambelane neenkcukacha ezahlukeneyo zomkhono.Ngoku i-wrench ye-torque ye-mechanical isetyenziswa ngokuqhelekileyo kwiimarike, ngokukodwa ngokusebenzisa i-sleeve encedisayo inokushukunyiswa ukulawula ukuqina kwentwasahlobo, ukwenzela ukuba ulungelelanise ubungakanani be-torque.Umkhandi usikhetha njani isikrufu setorque esifanelekileyo?

1. Jonga imiyalelo kwaye ukhethe i-torque efanelekileyo

Ngaphambi kokuba sikhethe i-torque wrench, kuyacetyiswa ukuba siqwalasele imeko yokusetyenziswa.Uluhlu lwe-torque yebhayisikile kufuneka lube ngu-0-25 N · m;I-torque ye-injini yemoto ngokuqhelekileyo yi-30 N · m;I-torque efunekayo kwizithuthuthu idla ngokuba yi-5-25N · m, kunye nezikrufu zomntu ukuya kwi-70N · m.Zonke iimpawu ze-torque ezihambelanayo ziboniswa ngokubanzi kwimiyalelo yeemveliso ezahlukeneyo.

Ke abahlobo kwishishini lokulungisa iimoto kufuneka bakhethe uluhlu olwahlukileyo lwezixhobo xa besebenza.

2. Khetha intloko efanelekileyo yokuqhuba

Abanini be-DIY abaninzi ekugcinweni kwangaphambili baqwalasela kuphela ubungakanani be-torque kwaye bangayihoyi ingxaki ehambelana nomkhono kunye nentloko yokuqhuba, kwaye babuyisele umkhono emva naphambili, ngaloo ndlela ukulibazisa ukugcinwa kwemoto.

I-1/4 (i-Xiao Fei) intloko yokuqhuba ifanelekile ngokukodwa kwiimfuno ezichanekileyo;

I-3/8 (iZhongfei) idla ngokusetyenziswa kwiimoto, izithuthuthu kunye neebhayisekile kwimisebenzi eqhelekileyo, uluhlu olubanzi lwezicelo;

I-1/2 (impukane enkulu) intloko yokuqhubela phambili yeyona mfuno yomgangatho woshishino

3, 72 amazinyo uluhlu olubanzi lwesicelo

Ngokuya liphezulu inani lamazinyo esakhiwo se-torque wrench ratchet, incinci i-engile yokusebenza efunekayo kwimfuno yetorque efanayo, kunye nazo zonke iintlobo zeZithuba ezimxinwa zinokuhoywa ngokulula.

4. Umgangatho wemveliso ngowona ubalulekileyo

Isitshixo sokulungiswa kwe-torsion kukuqina kwentwasahlobo.Enye i-torsion ekhululekileyo incinci kwaye enye i-torsion eqinile inkulu.Into ebalulekileyo emisela ubomi benkonzo ye-torque wrench ngumgangatho wentwasahlobo.I-torque wrench esetyenziswa rhoqo, ingqalelo ngakumbi kufuneka ihlawulwe kumgangatho wemveliso.

5, ukuchaneka okuphezulu kunokwethenjelwa ngakumbi, isatifikethi siyimfuneko

Kudla ngokubakho amabanga ama-1-5 e-torsion force, kwaye ukuphinda-phinda kunye neempazamo zamabakala ama-3 ahambelanayo aphakathi kwe-±3%.Impazamo encinci, ithembekile ngakumbi i-torque.

Ukongezelela, ukuchaneka kwe-torque wrench kuya kutshintsha ngokuhamba kwexesha, ngoko ke kucetyiswa ukuba uhlaziywe ngokutsha liziko lobuchwephesha rhoqo ngamaxesha e-10000 okanye i-1 ngonyaka.
