Vim li cas sim mus txhim kho tshuab tshuab mould pneumatic?
Thaum ib lub taub ntim uas muaj tib lub ntim, tsim kom muaj huab cua tawm ntawm lub tshuab pwm yog ntau dua qhov uas los ntawm qhov txhaj tshuaj pwm.Tus ntim ntawm huab cua tawm ntawm qhov txhaj tshuaj tuaj pwm yog sib npaug ntawm cov kab noj hniav .Cov tshuab pwm, qhov ntim ntawm huab cua yuav tsum cais tawm yog sib npaug ntawm qhov pwm kab noj hniav rho tawm qhov ntim tom qab lub billet tau tshuab tuaj. Tus tom kawg yuav siv ntau qhov kev faib ua feem ntau, thiab tseem tshuav ib qho cua clamp ntawm cov mold billet thiab pwm kab noj hniav, tshwj xeeb tshaj yog rau lub ntim loj ntawm cov tshuab tua xws li lub thoob thawv thiab roj tank.Piv txwv li, qhov ntim ntawm cov pwm kab noj hniav yog li ntawm 145L, thiab lub ntim ntawm cov nyiaj hli instant yog li 90L. Nyob rau hauv txoj kev no, txog 55 L cua yuav raug tso tawm rau hauv theem kawg (li 2 ~ 3s) ntawm qhov tshuab molding. Ntxiv mus, lub siab hauv lub tshuab pwm yog me heev (feem ntau tsawg dua 1MPa) piv rau qhov txhaj tshuaj pwm.Txawm , cov kev cai siab yuav tsum tau ua rau kev qaug ntawm qhov tshuab pwm (tshwj xeeb tshaj yog cov pwm nrog kab noj hniav).
Yog tias cov kab tawm ntawm cov kabmob thiab cov cua tsis tuaj yeem ua kom tiav los yog tso tawm sai li sai tau, parison tsis tuaj yeem tawg sai sai thiab tsis tuaj yeem tiv tau nrog cov kab noj hniav zoo tom qab tshuab (tshwj xeeb tshaj yog cov ntug), ua rau cov khoom tsis zoo xws li qhov chaw npau taws, kev ua tsis zoo, tus cwj pwm tsis zoo, cawv rau qhov kev ua tau zoo ntawm cov khoom muag thiab lwm cov duab, tshwj xeeb tshaj yog thaum kev sib tw parison extrusion streaks los yog hniav tawg tuaj.Qhov kev ua pa kuj tau ntev lub sij hawm cua txias ntawm cov khoom, txo lawv cov khoom siv dag zog, ua rau tsis sib npaug ntawm phab ntsa thickness.Yog li no, peb yuav tsum sim los txhim kho qhov kev ua pa ntawm lub tshuab pwm.
