Dab tsi yog cov kev daws teeb meem rau kev co ntau dhau hauv cov tshuab kub khiav?

Qhov laj thawj tseem ceeb ntawm kev vibration ntau dhau hauv cov txheej txheem kub khiav yuav tsum tau hais ua ntej, pib nrog cov kev kho yooj yim tshaj plaws thiab ua haujlwm mus txog qhov nyuaj dua. Mature kho rau ntau yam ua rau muaj npe hauv qab no:

1. Kev vibration ntau dhau los ntawm cov txheej txheem tsis sib haum (kev daws teeb meem ceev tshaj plaws): txo qhov kev txhaj tshuaj ceev ntawm 15% mus rau 30%, smoothly kho lub tuav tuav, txo qhov cuam tshuam ntawm cov tshuaj yaj, thiab txo qis kev co excitation ntawm qhov chaw; txo qhov kev txhaj tshuaj molding tshuab pwm qhib thiab kaw nrawm kom txo qhov cuam tshuam ntawm pwm kaw thiab tiv thaiv kev sib kis ntawm sab nraud kev co mus rau qhov kub khiav; thiab, rau active vibration kub runners, ncaj qha txo cov zaus zaus kom tsawg dua 25 Hz los tiv thaiv cov ntau ntau.

2. Qhov nrov tshaj plaws, tsis tshua muaj nqi - kev daws teeb meem rau kev co ntau dhau los ntawm kev sib txuas ntawm xoob xoob yog los ntxuav cov kub khiav kev teeb tsa kev siv nto, tshem tawm cov kua nplaum uas seem thiab impurities, thiab kho flatness; nruj nreem txuas cov ntsia hlau diagonally thiab tusyees nyob rau hauv cov theem raws li lub chaw tsim tshuaj paus qhov yuav tsum tau torque kom tshem tawm cov kev twb kev txuas qhov khoob; hloov lub qub thiab deformed sealing gasket nruab nrab ntawm lub kub nozzle thiab lub manifold, realign thiab zawm, thiab kho qhov sib txawv wobble qhov teeb meem.

3. Tus Qauv Tsim/Resonance-Txoj kev vibration ntau dhau (hauv paus daws teeb meem)

Tsis Txaus Ntsig / Resonance: Ua kom luv luv ntawm qhov tsis muaj kev txhawb nqa, ntxiv siab - kub resistant auxiliary support blocks rau qhov loj -span manifold, boost system nruj, hloov lub ntuj zaus, thiab nyob twj ywm tawm ntawm resonance ntau yam;

Tsis muaj Vibration Damping Tsim: Siv stainless hlau damping kho lub tes tsho ntawm cov kub nozzles kom txo cov nozzle kev co amplitude; tso tooj liab-raws li, siab- kub resistant damping pads nruab nrab ntawm lub manifold thiab pwm phaj los tiv thaiv kev co kis tau tus mob thiab nqus ntau zog co;

Qhov tsis xws luag hauv kev tsim cov dej ntws muaj xws li kev sib tsoo ntawm phab ntsa sab hauv, ua kom lub vojvoog tig ntawm cov ntws channel, smoothing tawm cov kev hloov pauv tam sim ntawd hauv cross-section, txo qhov cuam tshuam los ntawm yaj turbulence, thiab tsis muaj zog qhov kev co.

4. Kev vibration ntau dhau los ntawm cov khoom qub

Hloov cov hnav- tawm thiab distorted kub nozzles thiab manifolds, kho distorted mounting siv qhov chaw, thiab chaw nyob dynamic imbalances coj los ntawm cov khoom deformation; hloov kho lub clamping mechanism tshem tawm, rov xam cov clamping quab yuam, thiab tshem tawm kev vibration los ntawm kev txhaj tshuaj molding tshuab nws tus kheej sway.
