Kev txiav txim siab yog tias lub bolt tau ua tsis tiav yuav tsum muaj kev tshuaj xyuas dav dav ntawm nws cov tsos, lub xeev kev ntxhov siab, thiab qhov chaw ua haujlwm. Cov hom tsis ua haujlwm feem ntau suav nrog kev tawg, xoob, corrosion, thiab qaug zog tawg. Kev tiv thaiv hinges ntawm kev xaiv scientific thiab standardized los ua ke.
Koj tsis tsuas yog txhawj xeeb txog seb nws puas tawg, tab sis kuj nrog kev txheeb xyuas cov teeb meem thaum ntxov thiab tiv thaiv kev raug mob. Tshwj xeeb tshaj yog nyob rau hauv cov khoom siv tu lossis engineering kev nyab xeeb scenarios, ib qho teeb meem me me ntawm cov ntsia hlau tuaj yeem ua rau muaj kev cuam tshuam cov saw hlau. Kev nkag siab txog cov cim qhia ua tsis tiav thiab kev paub txog kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau kev sib txuas tiag tiag.
Yuav ua li cas txiav txim siab yog tias Bolt tau ua tsis tiav?
Kev tshuaj xyuas qhov muag
Cracks lossis Fractures: Pom meej pob txha los yog tawg me me tshwm sim ntawm lub ntsia liaj qhov rooj los yog ntawm lub taub hau -shank transition fillet (tuaj yeem kuaj tau nrog lub iav magnifying los yog kev ntsuam xyuas penetrant).
Cov cim ntawm Loosening: Misaligned anti-loosing markings, deformed washers, thiab nce qhov sib txawv ntawm connectors.
Corrosion Marks: Reddish -xim av xeb, pitting, thiab ntsuab oxides tshwm nyob rau saum npoo (tshwj xeeb tshaj yog nyob rau hauv marine los yog ntub dej). Xov puas: Cov xov yog hnav, stripped, nyuaj rau ntsia hlau, los yog jammed thaum lub sij hawm disassembly.
Cov ntaub ntawv siv: Cua turbine flange bolt fractures feem ntau tshwm sim ntawm qhov hloov pauv ntawm lub taub hau, nrog cov pob txha tawg nthuav tawm ob qho tib si qaug zog thiab qhov chaw tawg tawg.
Kev ua haujlwm txawv txav: nce kev vibration, suab nrov txawv txav, thiab hloov chaw ntawm cov khoom sib txuas.
Kev saib xyuas ua ntej qhia pom tias lub zog clamping txo qis dua 15%.
Torque re-kev tshuaj xyuas qhia qhov txo qis hauv lub zog (ntau dua 20% hauv qab tus nqi pib).
