Hom thiab yam ntxwv ntawm mechanical hnav
Hom kev hnav khaub ncaws hauv machining feem ntau suav nrog kev hnav khaub ncaws hnav, hnav tawv tawv, hnav khaub ncaws hnav, thermal hnav, theem hloov hnav thiab hydrodynamic hnav.
Khiav nyob rau hauv hnav yog hnav ntawm machinery nyob rau hauv ib txwm load, ceev thiab lubrication tej yam kev mob. Hom kev hnav no feem ntau txhim kho qeeb thiab muaj kev cuam tshuam me ntsis rau kev ua haujlwm zoo nyob rau lub sijhawm luv.
Cov khoom siv tawv tawv yog tshwm sim los ntawm cov khoom hnav poob los ntawm qhov nws tus kheej los yog cov khoom nyuaj nkag mus rau hauv lub tshuab cuab yeej los ntawm sab nraud, uas tau muab sib xyaw rau hauv qhov chaw ua haujlwm thiab raug txiav los yog hauv av, ua rau muaj kev puas tsuaj ntawm ib feem, cuam tshuam loj rau kev ua haujlwm zoo.
Ntog qaug zog hnav yog qhov kev puas tsuaj ntawm qhov chaw uas tshwm sim los ntawm micro tawg los yog pitting pits nyob rau hauv qhov kev txiav txim ntawm alternating load. Hom kev hnav no feem ntau yog ze rau lub siab, lub cev nyhav, cov khoom siv tshuab, qhov loj me thiab lwm yam.
Kub hnav yog hais txog cov cua sov uas tsim los ntawm cov txheej txheem kev sib txhuam ntawm cov khoom ua haujlwm ntawm cov khoom, uas ua rau cov khoom tempered thiab softened, hlawv thiab wrinkled. Hom kev hnav no feem ntau tshwm sim nyob rau hauv high-speed thiab high-pressure zawv zawg kev sib txhuam, uas yog kev puas tsuaj thiab nrog kev sib tsoo hnav.
Corrosive hnav yog ib hom tshuaj ua haujlwm, uas yog, tshuaj corrosion ua rau hnav. Thaum qhov chaw ntawm qhov chaw yog nyob rau hauv kev sib cuag nrog cov kua qaub, alkali, ntsev kua los yog cov pa phem, nws yuav raug rau cov tshuaj yaig, los yog cov nto ntawm qhov chaw yuav tsum tau ua ke nrog oxygen los tsim cov tawv thiab nkig hlau oxides uas yooj yim rau. poob thiab hnav ib feem.
Kev hloov pauv theem yog hais txog kev hnav ntawm qhov chaw uas tshwm sim los ntawm kev ua haujlwm ntev ntawm qhov chaw ntawm qhov kub thiab txias, cua sov ntawm cov hlau qauv nplej rau ntawm qhov chaw ntawm qhov chaw, oxidation nyob ib ncig ntawm cov ciam teb, thiab cov cim me me, uas ua rau cov khoom tawg yooj yim thiab hnav tsis kam txo.
Hydrodynamic hnav yog qhov hnav ntawm qhov chaw uas tshwm sim los ntawm kev cuam tshuam ntawm cov kua lossis cov khoom sib xyaw ua kua rau ntawm qhov chaw ntawm qhov nrawm nrawm.
Ua rau ntawm qhov hnav thiab nws tiv thaiv
Qee qhov hnav yog nyob rau hauv qeb ntawm ib txwm hnav, xws li kev sib txhuam ntawm qhov chaw, hnav los ntawm cov khoom tawv tawv, qaug zog hnav ntawm qhov chaw nyob rau hauv lub sij hawm ntev alternating load, corrosion ntawm cov khoom los ntawm cov tshuaj, thiab cov kev hloov nyob rau hauv metallographic qauv los yog txuam cov khoom ntawm lub nto ntawm qhov chaw nyob rau hauv qhov kub thiab txias.
Rau kev sib txhuam ntawm qhov chaw, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom muaj kev huv thiab lubrication txaus. Rau kev hnav los ntawm cov khoom tawv tawv, nws yog ib qho tsim nyog los tiv thaiv cov khoom los ntawm kev nthuav tawm thiab xyuas kom meej tias cov khoom yog huv si thiab npog. Rau qhov qaug zog hnav ntawm qhov chaw tshwm sim los ntawm kev hloov mus sij hawm ntev, tshem tawm qhov sib txawv thiab xaiv cov roj lubricating uas tsim nyog tuaj yeem txo qhov kev vibration ntxiv ntawm lub kaw lus thiab txhim kho qhov tseeb ntawm cov khoom. Rau corrosion ntawm qhov chaw los ntawm cov tshuaj, cov tshuaj phem yuav tsum tau muab tshem tawm thiab corrosion kuj ntawm cov khoom yuav tsum tau txhim kho. Rau kev hloov pauv ntawm cov qauv metallographic lossis cov khoom sib txuam ntawm qhov chaw nyob rau hauv qhov kub thiab txias, sim txhim kho cov kev ua haujlwm, lossis siv cov khoom siv kub thiab hnav-resistant los ua cov khoom.
Kev hnav tsis zoo suav nrog kev hnav los ntawm kev kho lossis kev tsim khoom tsis ua raws li cov qauv tsim, hnav los ntawm kev ua txhaum ntawm cov txheej txheem kev khiav haujlwm, thiab hnav los ntawm kev thauj mus los tsis raug, thauj khoom thiab tshem tawm, thiab khaws cia. Txhawm rau tiv thaiv kev hnav zoo li no, peb yuav tsum nruj me ntsis xyuas cov khoom zoo, paub txog kev ua haujlwm zoo, ua tib zoo ua haujlwm, muaj kev paub txaus hoisting, thiab ua tib zoo saib xyuas kom tsis txhob ua haujlwm tsis raug.
