Ultrasonic vuam: kev teeb tsa tsis haum
Ua ntej tshaj plaws, nws yog ib qho tseem ceeb kom tsuas yog hloov ib qho ntsuas ntawm lub sijhawm. Yog tias koj hloov lub sijhawm vuam thiab lub zog tom qab thawj lub weld, koj yuav tsis tuaj yeem txiav txim siab txog qhov kev hloov twg yog qhov kev hloov zoo. Feem ntau, lub siab thiab vuam sijhawm muaj kev cuam tshuam. Yog tias koj nce siab, koj yuav tsum txo lub sijhawm vuam kom txais tib lub txiaj ntsig. Qee cov ntaub ntawv, xws li polypropylene, yuav xav tau ntau dua cov corrosive soldering. High-pressure vuam nyob rau lub sijhawm luv luv tej zaum yuav ua haujlwm zoo dua li kev siv lub sijhawm vuam ntev nyob ntawm kev ntsuas qis. Nkag siab txog cov khoom yas thiab kev sib raug zoo nrog cov kws xa khoom siv hlau tuaj yeem mus txoj hauv kev ntev los daws kev teeb tsa kev sib tw. Cov welders feem ntau muaj cov yam ntxwv xws li vuam los ntawm lub zog thiab quab yuam pib, uas muaj txiaj ntsig yog siv zoo.
Nov yog qee qhov sib txawv rau kev txiav txim siab:
Kev hloov pauv , piv txwv li tus nqi ntawm lub zog ntawm lub tshuab raj ntawm lub tshuab raj, muaj feem cuam tshuam los ntawm kev hloov pauv ntawm qhov feem piv lossis lub tshuab hluav taws xob / lub zog. Nws tuaj yeem tsim raws li "daim ntawv qhia yuav tsum muaj ntau yam". Feem ntau cov khoom siv manufacturers. Tus nqi no yog siv los xam txog qhov sib piv ntawm qhov sib txawv uas yuav tsum tau coj mus rau hauv qhov teeb meem transducer thiab lub zog nce tau horn. Feem ntau, cov yas semi-crystalline yuav tsum muaj ntau lub zog dua cov amorphous resins.
Qhov khiav ceev ntawm lub taub hau welder yuav tsum tau sau cia ua qhov chaw teeb tsa. Nws cov teebmeem feem ntau tau hais hauv inserts, riveting thiab polycarbonate vuam. Tus nqi no yuav tsum sib txawv ntawm qhov pib teeb tsa ntawm 2-4 nti / thib ob. Ua kom tiav cov txiaj ntsig tau. Kev tswj hydraulic ceev feem ntau muab kev tswj zoo heev.
Kev sib thooj / qib theem ntawm lub tshuab raj, kho thiab cuam tshuam qhov tseeb kuj yog qhov tseem ceeb. Ntxiv nrog rau txhawm rau kho lub tshuab raj thiab lub duav rov qab, yuav tsum muaj txoj hauv kev los ua kom lub tshuab raj thiab qib sib tiv toj hauv cov twj / vuam. Raws li tau hais dhau los, qhov ua tiav, qib ntsia hlau ntawm lub kaum ntawm pawg tswj hwm yuav yog tus qauv yooj yooj yim thiab siv tau zoo, txawm hais tias lwm tus ceeb toom tawm tsam kev siv qib screws lossis "jack screws." Nws raug nquahu kom siv cov roj av gasket los ua qhov kev xaiv zoo dua. Yog tias siv lub ntsej muag jack, nws yog ib qho tseem ceeb uas tsuas yog ob ntawm plaub tus tau siv thaum coj los sib hais. Nyob rau hauv txhua rooj plaub, leveling saib xyuas qhov tsis txawv vuam thoob plaws qhov chaw sib txuas nrog welded.
Cov pa roj carbon ntawv tso rau hauv nruab nrab ntawm lub tshuab raj thiab cov ntu lossis cov khoom siv hluav taws xob tuaj yeem siv los qhia thawj qhov chaw sib tiv tauj, thiab feem txuas welded tuaj yeem tawg kom kuaj xyuas qhov degree ntawm soldering. Qeb qib tom qab ntawd tuaj yeem siv los tsa (lossis siv ntau zog) rau thaj chaw uas tsis muaj vuam. Qee zaum lub taub hau weld yuav tsum tsis txhob yaug nrog lub clamp kom ntseeg tau tias qhov zoo tshaj plaws vuam kev sib tw. Siv lub npe hu ua "zoo" ntawm qhov kawg khiav mus ua kom haum lub ntsaj nrog lub zes yog qhov kev tiv thaiv tiag tiag.
Vuam / khaws cia yog qhov ntau npaum li cas ntawm cov quab yuam ua kom lub tshuab ua rau ntawm lub tshuab raj thiab lub qhov thaum lub sijhawm vuam thiab tuav cov txheej txheem. Qhov pib kwv yees ntawm cov txiaj ntsig zoo siv tau yog siv los ntawm tag nrho qhov sib koom ua ke ntev (hauv kab tawm) thiab qhia hauv cov duab. Cov txheej txheem tau ua tiav zoo raws li cov lus qhia dav dav no. Feem ntau, qhov loj me xav tau siv zog ntau dua. Qee lub tshuab hluav taws xob nyob hauv lub tshuab txais tam sim no tso cai rau lub zog hloov thaum lub sijhawm vuam mus ua kom muaj kev tswj hwm ntau dua ntawm cov cua kub ntawm cov khoom sib txuas thiab cov vau tsoo ntawm cov khoom.
Tus txhais forc e yog qhov preload siv rau ntu ua ntej ultrasonic yoj qhib. Cov ntawv thov feem ntau xav tau qhov preload no rau "nruab" hauv qhov chaw los tso cov ntu ua ntej ua ntej vuam. Tus nqi ua raws li tag nrho ntev ntawm qhov sib koom tes. Ib qho khoov duav lossis deformed yuav txuas zoo dua ntawm cov rog ntau dua lossis ultrasonic vuam ntawm qhov kev ncua deb. Cov ntawv thov xws li kev nkag mus, riveting, thiab forging tej zaum yuav xav tau ua ntej ntawm kev ua kom muaj zog ntawm cov ultrasonic ua ntej lub tshuab raj hu rau lub workpiece, uas tso cai rau machining pib nrog me me lossis tsis tau pib quab yuam.
