Qhov tseem ceeb thiab txoj hauv kev ua haujlwm ntawm fasteners

Fastenerstau dav siv thiab tuav txoj haujlwm tseem ceeb hauv kev lag luam tsheb! Qhov nruab nrab, ib lub tsheb siv txog 500 hom fasteners ib 50Kg / 4000 daim; Muaj ntau tshaj 88Kg / 7100 daim, ntawm cov uas muaj zog fasteners suav txog li 1/3. Tus nqi ntawm cov fasteners ntawm lub tsheb yog kwv yees li 2.5 feem pua ​​​​ntawm cov nqi ntawm lub tsheb, suav txog 40 feem pua ​​​​ntawm tag nrho cov naj npawb ntawm cov hauv paus ntawm lub tsheb, thiab kev ua haujlwm ntawm kev sib txuas ntawm cov kab sib dhos yog kwv yees li 70 feem pua!

1. Qhov tseem ceeb ntawmfasteners

Siv lub zog me me heev thiab lub gasket yuav tsis haum zoo; siv zog ntau dhau thiab cov xov yuav raug hnav. Raws li cov ntaub ntawv tau tshaj tawm tsis ntev los no, 23 feem pua ​​​​ntawm cov teeb meem kho tsheb hauv kev lag luam tsheb yog tshwm sim los ntawm kev xoob fasteners, thiab 12 feem pua ​​​​ntawm cov tsheb tshiab muaj cov fasteners uas tsis zoo nruj. Bolts yog ib qho tseem ceeb tshaj plaws uas txiav txim siab qhov zoo ntawm kev sib dhos, thiab qhov tsis ua haujlwm ntawm threaded fasteners kom ncav cuag lub peev xwm sib xws yog qhov tseem ceeb ntawm kev sib tsoo!

2. Fastener bolt zawm txoj cai

Lub bolt kev twb kev txuas yuav tsum muaj peev xwm tiv thaiv sab nraud quab yuam, kom cov khoom sib dhos yuav tsis txav mus rau hauv kev sib cais, txwv tsis pub nws yuav ua rau cov ntsia liaj qhov rooj plam, puas lossis poob.

Yog li ntawd, peb tsim qhov tsawg kawg nkaus clamping quab yuam ntawm lub ntsia liaj qhov rooj, uas yuav tsum muaj peev xwm tiv thaiv lub clamping ib feem ntawm kev sib cais vim yog sab nraud quab yuam, thiab kom muaj kev sib txhuam clamping los yog xyuas kom meej sealing, thiab lwm yam.

Lub ntsia liaj qhov rooj yog muab tso rau hauv ib qho kev sib txuas, thiab cov txiv ntoo los yog cov xov sab hauv yog nruj nreem kom lub bolt stretch thiab deform. Qhov no elastic deformation tsim ib tug axial tensile quab yuam, uas squeezes lub clamped qhov chaw ua ke, uas yog hu ua pre-tightening quab yuam.

Txoj kev xav, tsuav yog tsim kom muaj lub zog clamping txaus, cov khoom clamped tuaj yeem lav tau ua haujlwm nyab xeeb hauv qhov chaw hnyav xws li kev co, siab thiab qis kub, tsis tas siv txoj kev pabcuam xws li gluing.

3. Clamping quab yuam ntawm fasteners

Lub hom phiaj ib leeg ntawm cov txheej txheem nruj yog tswj hwm lub zog clamping nyob rau hauv qhov tsim nyog kam rau ua!

Thaum lub sij hawm sib dhos, lub clamping quab yuam yuav tsum loj txaus kom ntseeg tau tias cov khoom sib dhos yuav tsis txav mus rau ib leeg. Tab sis tib lub sij hawm, nws yuav tsum tau xyuas kom meej tias lub clamping quab yuam siv thaum lub sij hawm nruj yuav tsis puas los yog plastically deform lub ntsia liaj qhov rooj.

Clamping quab yuam tswj yog lub hom phiaj tseem ceeb ntawm bolt sib dhos, kev tswj tsis raug ntawm clamping quab yuam yuav ua rau muaj qhov tshwm sim loj.

4. Torque faib

Los ntawm oiling nto ntawm lub fastener, qhov kev sib txhuam quab yuam yuav txo tau thiab lub pre-tightening quab yuam yuav tsum tau nce nyob rau hauv tib lub torque. Hauv lwm lo lus, kom ua tiav tib lub zog nruj, lub zog xav tau rau cov roj bolts yuav tsum me dua.

Torque detection method:

① Loosening txoj kev: Tom qab loosening, nws yuav tsum tau nruj nreem, uas yog teeb meem rau kev khiav hauj lwm thiab tsis tshua muaj siv;

② Fastening txoj kev: feem ntau yog siv, nrhiav kom tau torque loj dua qhov tseeb zawm torque ntau;

③ Kev kos cim: qhov tseeb tshaj plaws, kev ua haujlwm nyuaj, tsis tshua siv.

5. Feem ntau siv txoj kev nruj rau cov fasteners

Torque tswj txoj kev: Nws yog txoj kev siv nruj tshaj plaws, haum rau feem ntau cov ntsia hlau txuas tsis tseem ceeb.

Disadvantages: Nws muaj kev cuam tshuam zoo heev los ntawm kev sib txhuam coefficient, lub clamping quab yuam yog discrete, thiab kev siv tus nqi ntawm cov khoom siv ntsia hlau yog tsawg.

Lwm txoj hauv kev nruj xws li torque-angle tswj txoj kev thiab yield point tswj txoj kev.
