Bolt Tightening Method
Aug 01, 2024
Bolt zawm yog qhov tseem ceeb heev ntawm kev sib dhos tshuab. Nws yog ncaj qha ntsig txog kev sib txuas ruaj khov ntawm cov khoom sib dhos thiab ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb ntawm cov cuab yeej siv tshuab. Yog li ntawd, txoj kev raug ntsia liaj qhov rooj yog qhov tsim nyog heev. Niaj hnub no, Hanpu Vivian yuav qhia ntau txoj hauv kev nruj nruj rau koj, vam tias yuav pab tau rau koj.
Ua ntej ntawm tag nrho cov, feem ntau txoj kev ntawm bolt zawm yog txoj kev torque. Txoj kev torque yog ib txoj hauv kev nruj los ntawm kev siv qee qhov torque rau lub bolt. Thaum siv txoj kev torque, nws yog ib qho tsim nyog los txiav txim siab qhov tsim nyog tus nqi torque raws li cov lus qhia thiab cov khoom siv ntawm lub ntsia liaj qhov rooj, uas feem ntau tuaj yeem ua tiav nrog lub torque wrench. Qhov kom zoo dua ntawm txoj kev torque yog tias nws yooj yim rau kev khiav lag luam thiab tuaj yeem ua kom lub zog nruj ntawm lub bolt raws li qhov yuav tsum tau ua. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias lub torque yuav tsum raug xaiv kom raug. Loj dhau los yog me me dhau lawm yuav cuam tshuam cov nyhuv zawm ntawm lub bolt.
Thib ob, lwm txoj hauv kev nruj nruj yog txoj kev ncab. Txoj kev ncab yog ib txoj hauv kev nruj los ntawm kev siv lub zog tensile rau lub bolt. Thaum siv txoj kev stretching, hydraulic stretching khoom los yog hydraulic torque wrenches feem ntau yog siv. Qhov kom zoo dua ntawm txoj kev ncab yog tias nws tuaj yeem ua kom lub zog nruj ntawm lub ntsia liaj qhov rooj, txo qhov qaug zog ntawm lub ntsia liaj qhov rooj, thiab txuas ntxiv kev pab cuam lub neej. Txawm li cas los xij, txoj kev ncab yuav tsum muaj cov cuab yeej tshwj xeeb thaum lub sijhawm ua haujlwm, uas yog kim thiab yuav tsum tau siv tshuab ua haujlwm siab.
Tsis tas li ntawd, muaj lwm txoj kev ntawm bolt zawm, uas yog lub kaum sab xis txoj kev. Lub kaum sab xis txoj kev yog ib txoj hauv kev nruj los ntawm kev siv lub kaum sab xis rau lub bolt. Thaum siv lub kaum sab xis txoj kev, lub kaum sab xis torque ciaj ntswj los yog lub kaum sab xis ntsuas ntsuas feem ntau yog siv. Qhov kom zoo dua ntawm txoj kev lub kaum sab xis yog tias nws tuaj yeem tswj qhov nruj nruj ntawm lub ntsia liaj qhov rooj, thiab nws tuaj yeem zam qhov teeb meem ntawm qhov tsis sib xws ntawm lub zog nruj los ntawm qhov tsis sib xws ntawm qhov ntsia hlau ntev. Txawm li cas los xij, thaum ua haujlwm ntawm lub kaum sab xis txoj kev, kev sib txhuam coefficient ntawm lub ntsia liaj qhov rooj thiab cov txiv ntoo, nrog rau cov khoom siv thiab kev kho saum npoo ntawm lub ntsia liaj qhov rooj yuav tsum tau txiav txim siab kom ntseeg tau tias lub zog nruj raws li qhov yuav tsum tau ua.
Thaum kawg, muaj lwm txoj kev bolt fastening, uas yog kev sib txuas. Txoj kev sib txuas yog ib txoj hauv kev los ntawm kev sib txuas los ntawm cov nplaum nplaum rau ntawm qhov chaw ntawm lub bolt xov. Thaum siv txoj kev sib khi, koj yuav tsum tau them sai sai rau kev xaiv cov nplaum uas tsim nyog thiab xav txog qhov cuam tshuam ntawm qhov kub thiab av noo ntawm kev siv ib puag ncig ntawm cov nplaum. Qhov kom zoo dua ntawm txoj kev sib txuas yog tias nws tuaj yeem txhim kho lub bolt lub peev xwm los tiv thaiv xoob, txo qhov qaug zog ntawm lub ntsia liaj qhov rooj, thiab txuas ntxiv nws lub neej kev pab cuam. Txawm li cas los xij, txoj kev sib txuas yuav tsum tau xav txog kev ua haujlwm ntawm lub neej thiab kev hloov pauv ib puag ncig ntawm cov nplaum kom ntseeg tau tias lub bolt lub fastening nyhuv yog ntev-ntev thiab ruaj khov.
Shandong Hanpu yog cov chaw tsim khoom hauv Suav teb tshwj xeeb hauv kev tsim cov khoom siv ntau yam ntsia liaj qhov rooj. Nws muaj tag nrho cov qauv ntawm cov ciaj ntswj uas tuaj yeem nruj bolts ntawm cov qauv sib txawv thiab qib zog. Qee cov qauv muag zoo tshaj plaws yog raws li hauv qab no:
