Daim ntawv thov PI9200E mus tas li hlau nplaum non-inductive synchronous zaus converter hauv transformation kev txhaj tshuaj molding tshuab
Txheeb xyuas
Txhaj tshuaj molding cov cav tov thiab extruders yog cov khoom tsim tawm hauv cov khoom lag luam plastics. Lawv kuj yog cov khoom siv hluav taws xob uas tseem ceeb. Lawv raug hu ua "hluav taws xob tsiv", thiab lawv cov hluav taws xob tau them nyiaj rau txog 80% ntawm cov hluav taws xob uas tsim los ntawm cov lag luam. Kev txhaj tshuaj molding tshuab siv ib qho loj npaum li hluav taws xob, uas nyob ntawm tes ua rau cov khoom siv hluav taws xob loj loj hauv tag nrho lub zej zog. Ntawm qhov tod tes, qhov tsim nqi ntawm cov lag luam tseem nyob siab, thiab cov khoom tsis muaj kev sib tw kom zoo dua, uas cuam tshuam rau cov kev pabcuam nyiaj txiag ntawm lub tuam txhab.
Txoj kev txhaj tshuaj molding tshuab feem ntau muab faib ua ntau theem, xws li clamping, txhaj, yaj, tuav, txias, thiab pwm qhib. Txhua theem yuav tsum ua haujlwm sib txawv thiab khiav. Rau cov roj tsav lub cev, txoj kev txhaj tshuaj molding yog nyob rau hauv lub xeev hloov load. Nyob hauv lub kaw lus hydraulic ntawm lub twj tso kua tshuaj, lub tshuab tso kua roj yeej ib txwm ntws ntawm qhov ceev, thiab hydraulic cov roj rov qab los ntawm cov txeej valve. Cov txheej txheem no yog hu ua kev kub ntxhov siab. Raws li statistics, lub zog poob los ntawm high-pressure throttling yog siab li 25-60%. Thaum tib lub sij hawm, vim yog lub sij hawm ntev khiav ceev ntawm hydraulic kua, qhov sib zog txhuam nrog qhov hydraulic thiab qhov chaw ua rau ua rau cov roj kub kom siab dhau, lub suab nrov loj heev, thiab lub neej ua haujlwm yog luv dua.
Qhov ob, PI9000 qhov kev txhim kho cov txheej txheem luv luv
Hauv cov hlau nplaum synchronous transformation ntawm kev txhaj molding tshuab, cov tswvyim tswj txais txoj kev uas qhov kev khiav thiab siab ob lub teeb tawm raug sib piv thiab loj dua, thiab cov tswvyim tswj xyuas kom paub meej tias tus neeg siv qhov kev txwv ntawm cov khoom siv ntawm qhov hloov pwm . Tshaj tej ntawm, cov teeb liab tswj fais fab tag nrho los ntawm kev txhaj tshuaj molding tshuab, uas tsis ua rau cuam tshuam rau kev txhaj tshuaj molding tshuab thiab cuam tshuam cov khoom zoo.
1, xaiv cov zaus sib hloov
Cov roj twj siv hauv qhov kev hloov kho moulding tshuab yog ib 14KW ruaj khov magnet tsis-inductive synchronous servo tsav. Vim li no, tus inverter siv PI9230E015G3 tas li hlau nplaum synchronous non-inductive vector tswj tshwj xeeb inverter. Yuav kom ua tau raws li kev tswj kav ntawm kev pib ua kom sai ntawm txoj kev txhaj tshuaj molding, yuav tsum tau xaiv ib qho uas yuav tsum tau braking resistor. Raws li cov braking resistor xaiv tswj ntawm qhov inverter, configure lub 40Ω / 1500W braking resistor.
2, inverter tswj lub davhlau ya nyob twg
Raws li kev tswj cov txheej txheem ntawm cov kev txhaj molding tshuab, cov kev siv hluav taws xob sab hauv siv lub tshuab analog tswj AI1, AI2, GND. Cov tswj kev tswj digital DI1, DI2, COM. Qhov kev xa tawm sab nraud 1 terminals TA1 thiab TC1.
