Ukuvikelwa kwengcindezi yemishini yokufaka ifilimu elula

Ukuvikelwa kwamandla kagesi kanye nokwelula ukupakisha ifilimu. Njengenye ye-vacuum ezenzakalelayo umshini wokupakisha Uma umshini wokupakisha wefilimu yokwelula, izingxenye zawo zangaphakathi zemoto noma zikagesi zisebenza ngaphansi kwe-voltage elinganisiwe, i-voltage iphezulu kakhulu, iphansi kakhulu noma isici somuntu enqubweni yokusebenza silahlekelwa amandla ngokuzumayo, singadala umonakalo emishinini noma ekulimaleni kwabasebenzi, ngakho-ke ekwakhiweni kwesekethe yokulawula kagesi, ngokwezidingo zangempela, setha isivikelo, isivikelo se-overvoltage kanye nokulahlekelwa yingcindezi ngaphansi kwesivikelo se-voltage.

1. Ukuvikelwa kwamandla kagesi okupakisha ifilimu yokwelula kwe-zero voltage, ukuvikelwa kwamandla aphansi

Ukuvikelwa kwamandla kagesi nokwelula ukupakisha ifilimu. Umshini wokupakisha we-vacuum wefilimu yokwelula uma kwenzeka igridi kagesi isebenza ngokuzumayo, imoto izoma, futhi izomisa ukukhiqizwa kwezingxenye ezihambayo zemishini. Ngokuvamile opharetha abakwazi ukuvula iswishi kagesi ngesikhathi esifanele, uma kungenziwa lutho, lapho i-vacuum yefilimu yokwelula ukupakisha i-vacuum ibuyela esimweni sayo esijwayelekile, imoto izoqala yodwa, cishe izobangela izingozi zopharetha nemishini, kanye namandla phezu kwamandla kagesi kanye nokwehla kwamandla kagesi ngokushesha. Ngakho-ke udinga ukuthatha izinyathelo zokuvikela i-voltage engu-zero.

Kulayini wokupakisha we-vacuum we-vacuum wokulawula ugesi, i-voltage engu-zero yi-contactor kanye nokuvikelwa kwe-relay ephakathi. Lapho ugesi wegridi uphela, i-contactor kanye ne-relay current ziphela, i-contactor iyasetha kabusha, ukuze kunqunywe ukunikezwa kwamandla kwesekethe eyinhloko kanye nesekethe yokulawula.

lapho i-stretch film packing mechanical kanye ne-electric source voltage ibuyela esimweni esijwayelekile, uma ungacindezeli inkinobho yokuqala, i-motor ngeke iqale yodwa, futhi ukuvikelwa kwe-voltage okungelutho lapho i-grid voltage iphela, i-motor izosebenza ngaphansi kwe-under voltage, isivinini se-motor sehlile, kufakwe i-stator winding current. Ngenxa yokuthi akukho amplitude current eyanele engezwayo ukwenza i-fuse kanye ne-thermal relay action, ayinikezwanga sivikelo, ngakho-ke lezi zinhlobo ezimbili zemishini kagesi uma ingathathi izinyathelo zokuzivikela, ukunweba kuzoshisa kakhulu umonakalo we-motor ngokuhamba kwesikhathi.

Ngakolunye uhlangothi, i-ow voltage izobangela ukukhishwa kukagesi, yenze isekethe ingasebenzi, futhi ingaholela engozini yomuntu siqu kanye nemishini. Ngakho-ke kufanele ugweme ukusebenza kwenjini ngaphansi kwe-under voltage.

Isisetshenziswa sikagesi sokuvikela ama-voltage aphansi sangempela siyi-relay ye-voltage kagesi kanye ne-contactor. Esifundeni sokulawula sikagesi sokupakisha ifilimu elula, kunemigqa embalwa kuphela efakiwe i-relay ekhethekile ye-voltage kagesi enendima yokuvikela ama-voltage aphansi, futhi ngenxa yokuthi iningi le-contactor yesifunda sokulawula futhi linomsebenzi wokuvikela ama-voltage aphansi, ngakho-ke awuzange ufake imishini kagesi yokuvikela ama-voltage aphansi, ngokuvamile lapho i-voltage yegridi yehliswa ibe ngaphansi kwamaphesenti angamashumi ayisishiyagalombili nanhlanu we-voltage elinganisiwe, i-contactor ye-voltage relay noma isenzo, ukuze kunqunywe isekethe eyinhloko kanye nokunikezwa kwamandla kwesekethe yokulawula, kwenza imoto ime.

2. Ukuvikelwa kokuvikelwa kwamandla kagesi kanye nokwelula ukupakisha ifilimu

ukuvikelwa kwe-stretch film packing mechanical kanye ne-electric voltage. I-Electromagnet, i-electromagnetic sucker kanye neminye imithwalo emikhulu ye-inductance kanye nezikhungo ze-DC electromagnetic, i-dc relay, njll. Ngokuvamile, izokhiqiza amandla aphezulu e-electromotive induction, izokwenza ukuwohloka nokulimala kwe-electromagnetic coil insulation. Ngakho-ke udinga ukusebenzisa ukuvikelwa kwe-overvoltage. Ngokuvamile kwisekethe yokuxhumana yomshini wokupakisha we-stretch film, i-resistor kanye ne-capacitor zihambisana kuzo zombili izinhlangothi zekhoyili, zesekethe ye-dc, ku-diode zihambisana kuzo zombili izinhlangothi zekhoyili, ukuze kwakheke isekethe yokukhipha, ukuvikelwa kwe-overvoltage.

Ukuthembela okwandayo ekusetshenzisweni kwe-weigher checkweigher kwenze izinguquko eziningi embonini ye-multihead weigers eminyakeni edlule.

Ngaphezu kwakho konke, silindele ukuba udumo emiphakathini esiyisebenzelayo, umthombo obalulekile kumakhasimende ethu, kanye nendawo lapho isikali sethu esizinikele singakhula futhi sichume khona.

Isikali somshini wokukala siyisistimu esebenza kuzo zonke izinhlobo ekwazi ukugcina amakhulu amapharamitha enqubo yokulinganisa isisindo ukuze inikeze amaphrofayili esikali esinamakhanda amaningi ngokwezifiso zohlobo ngalunye lomshini wokukala kanye nokucushwa kwesikali sokulinganisa isisindo.

isikali sesisindo esinezinhloko eziningi singashintshwa ukuze sisetshenziswe kunoma yimuphi umshini wokulinganisa futhi sifanelekela isikali sokulinganisa.
