Puas Yog Kev Hnav Thiab Tiab ntawm Lub Tshuab Ntim Muaj Kev cuam tshuam loj?
Feb 28, 2022
Hnav thiab tsim kua muag ntawm cov khoom ntim tshuab
Kev hnav lub cev thaum siv cov khoom siv suav nrog ob qho tib si hnav thiab hnav tsis zoo tshwm sim los ntawm kev khaws cia, kev siv tsis raug thiab corrosion los ntawm ntuj tsim (tsim los ntawm kev ua haujlwm hnyav). Qhov tshwm sim ntawm kev hnav thiab tsim kua muag ntawm lub tshuab ntim khoom, feem ntau tshwm sim raws li:
(1) Hloov qhov loj me ntawm cov khoom thiab cov khoom uas ua rau cov khoom siv. Thaum hnav mus rau ib qho twg, nws yuav txawm hloov qhov geometry ntawm cov khoom thiab cov khoom.
(2) Hloov qhov xwm txheej ntawm kev sib koom ua ke ntawm cov khoom thiab cov khoom sib txuas, uas ua rau xoob xaim thiab txo qhov raug thiab ua haujlwm tau zoo.
(3) Kev puas tsuaj rau qhov chaw, lossis txawm tias muaj kev puas tsuaj rau lwm qhov chaw uas cuam tshuam nrog nws vim yog kev puas tsuaj rau ib tus neeg, ua rau muaj kev puas tsuaj rau tag nrho cov khoom, ua rau muaj xwm txheej loj.
Hnav cov theem ntawm lub tshuab ntim khoom
Nyob rau hauv ib txwm muaj xwm txheej, thaum siv cov cuab yeej siv, kev hnav ntawm cov khoom thiab cov khoom muaj qee yam kev cai, uas tuaj yeem faib ua peb theem:
Thawj theem: thawj theem hnav (tseem hu ua kev khiav -hauv theem hnav). Nyob rau theem no, macro-geometry thiab micro-geometry (roughness) ntawm txhua feem thiab cov khoom siv saum npoo ntawm cov khoom yuav tsum tau hloov pauv loj. Yog vim li cas rau qhov tshwm sim no yog tias nyob rau hauv cov txheej txheem ntawm machining thiab manufacturing, txawm li cas los xij ntawm precision machining, qhov saum npoo ntawm cov khoom tseem muaj qee yam roughness. Thaum mating nrog ib leeg rau kev txheeb ze, xws li cov tawv tawv hnav vim kev sib txhuam. Tus hnav tus nqi ntawm lub sij hawm no yog ceev heev, thiab tus nqi thiab lub sij hawm ntawm hnav nyob ntawm seb qhov roughness ntawm qhov chaw. Qhov tshwm sim no feem ntau tshwm sim hauv kev sib sau ua ke thiab kev ua haujlwm ntawm cov cuab yeej tsim khoom thiab kho, thiab cov theem pib thiab pib siv thaum lub sij hawm commissioning thiab pib siv lub sij hawm.
Qhov thib ob theem: Tom qab qhov chaw ntawm cov txheeb ze txav mus los thiab cov khoom yog hnav thiab hnav, qhov hnav nkag mus rau theem ob, uas yog, qhov hnav ib txwm muaj. Thaum lub sij hawm no, yog hais tias cov kev ua hauj lwm tej yam kev mob ntawm cov khoom nyob twj ywm unchanged los yog hloov me ntsis, tus hnav ris tsho nce nyob rau hauv tus nqi tas li nrog lub sij hawm. Qhov ntawd yog hais tias, nyob rau hauv ib txwm muaj xwm txheej, qhov chaw thiab cov khoom siv qeeb heev. Thaum hnav mus txog ib theem thiab qhov tsis tuaj yeem ua haujlwm txuas ntxiv, lub sijhawm ntawm theem no yog lub neej ua haujlwm ntawm ib feem.
Qhov thib peb theem: hnyav hnav theem. Cov tsos mob ntawm cov theem no feem ntau yog vim qhov tseeb tias cov khoom tau mus txog lawv lub neej thiab siv txuas ntxiv mus, uas ua rau kev sib raug zoo ntawm kev hnav, ua rau hnyav hnyav, thiab ua rau muaj kev hnav ntau heev, ua rau muaj kev poob qis hauv cov khoom siv. raug, kev ua tau zoo thiab kev ua haujlwm ntawm cov tshuab thiab khoom siv. Piv txwv li, kev sib txhuam kev sib txhuam ntawm cov ncej thiab cov zawv zawg bearings ntawm cov cuab yeej siv tshuab, nyob rau hauv ib txwm muaj xwm txheej, yog sib cais los ntawm cov kua los yog ib nrab -kua nyob rau hauv qhov sib nrig sib haum, kom lawv tsis txhob ncaj qha kev sib txhuam. Thaum cov ncej lossis cov kabmob hnav mus rau qee qhov thiab siv txuas ntxiv, cov roj lossis roj yuav tsis txaus vim qhov kev tshem tawm ntau ntxiv, thiab cov kua dej sib txhuam yuav poob nws cov nyhuv, ua rau kev sib txhuam ncaj qha ntawm cov ncej thiab cov kabmob. , thiab hnav yuav aggravated.
Paub txog txoj cai no, peb tuaj yeem ua rau thawj theem hnav kom luv li sai tau, lub sijhawm hnav ib txwm ntev li ntev tau, thiab zam kev hnav khaub ncaws hnyav. Thawj theem hnav yog luv luv, qhia tau hais tias cov khoom siv thiab cov khoom siv tau zoo.
