Kodi makina a PLC omwe amagwiritsidwa ntchito mumakina opakira ndi ati?

Kuti zinthu ziyende bwino m'mabizinesi amakono, kuwongolera njira zodalirika komanso makina odziyimira pawokha ndikofunikira kwambiri. Makina odzaza zinthu pogwiritsa ntchito makina odziyimira pawokha a PLC amawonjezera phindu pa ntchito zopangira. Ndi PLC, ntchito zovuta zimakhala zosavuta kukhazikitsa ndikuwongolera. Makina a PLC ndi ofunikira kwambiri kuti mafakitale ambiri apambane, kuphatikizapo mafakitale opangira zinthu zopaka, mankhwala, chakudya, ndi zakumwa zipambane. Chonde pitirizani kuwerenga kuti mumvetse zambiri za makina a PLC ndi ubale wake ndi makina odzaza zinthu.

Kodi dongosolo la PLC ndi chiyani?

PLC imayimira "programmable logic controller," lomwe ndi dzina lake lonse. Popeza ukadaulo wamakono wolongedza katundu wakhala wopangidwa ndi makina komanso wodziyimira pawokha, kuchuluka kwa katundu wolongedza katundu kuyenera kukhala kolondola, chifukwa izi zimakhudza momwe katunduyo alili komanso momwe zinthu zilili pachuma.

Mafakitale ambiri amagwiritsa ntchito mizere yolumikizira yokha yokha pankhaniyi. Dongosolo la PLC ndilofunika kwambiri kuti mzere wolumikizira uwu ugwire bwino ntchito. Popeza ukadaulo wapita patsogolo, pafupifupi zinthu zonse zapamwamba zopangira makina opaka zinthu tsopano zili ndi mapanelo owongolera a PLC, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito kuposa kale lonse.

Mitundu ya PLC

Malinga ndi mtundu wa zotulutsa zomwe amapanga, ma PLC amagawidwa m'magulu motere:

· Chotulutsa cha transistor

· Zotsatira za Triac

· Kutulutsa kwa Relay

Ubwino wa makina a PLC okhala ndi makina opakira

Panali nthawi ina pomwe makina a PLC sanali mbali ya makina opakira, monga makina otsekera ndi manja. Chifukwa chake, ogwira ntchito ena ankafunika kuti atsimikizire kuti ntchitoyi yachitika. Komabe, zotsatira zake zinali zokhumudwitsa. Ndalama zomwe zinkagwiritsidwa ntchito nthawi ndi ndalama zinali zambiri.

Komabe, zonse zinasintha pamene makina a PLC anafika omwe anaikidwa mkati mwa makina opakira.

Tsopano, makina angapo odziyimira pawokha amatha kugwira ntchito limodzi bwino kwambiri. Mutha kugwiritsa ntchito makina a PLC kuti muyese bwino zinthuzo, kenako kuziyika kuti zitumizidwe. Kuphatikiza apo, makinawo ali ndi sikirini yowongolera ya PLC komwe mungasinthe izi:

· Kutalika kwa thumba

· Liwiro

· Matumba a unyolo

· Chilankhulo ndi Khodi

· Kutentha

· Zambiri

Zimamasula anthu ndipo zimapangitsa chilichonse kukhala chosavuta komanso chosavuta kugwiritsa ntchito.

Kuphatikiza apo, ma PLC amapangidwa kuti azikhala nthawi yayitali, kotero amatha kupirira nyengo zovuta, kuphatikizapo kutentha kwambiri, magetsi othamanga, mpweya wonyowa, ndi mayendedwe ogwedezeka. Ma logic controller ndi osiyana ndi makompyuta ena chifukwa amapereka input/output yayikulu (I/O) yowongolera ndikuyang'anira ma actuator ndi masensa ambiri.

Makina a PLC amabweretsanso maubwino ena ambiri pamakina opakira. Ena mwa iwo ndi awa:

Kugwiritsa ntchito mosavuta

Katswiri wa mapulogalamu apakompyuta safunika kulemba khodi ya PLC. Yapangidwa kuti ikhale yosavuta, ndipo mutha kuyidziwa bwino mkati mwa milungu ingapo. Chifukwa chake imagwiritsa ntchito:

· Mawonekedwe a makwerero owongolera ma relay

· mawu olamula

Pomaliza, ma graph a makwerero ndi osavuta kumva komanso osavuta kuwagwiritsa ntchito chifukwa cha mawonekedwe awo.

Magwiridwe antchito odalirika nthawi zonse

Ma PLC amagwiritsa ntchito makompyuta ang'onoang'ono okhala ndi chip chimodzi, zomwe zimapangitsa kuti azilumikizana bwino kwambiri, komanso ntchito zodzitetezera komanso zodzidziwitsa zomwe zimawonjezera kudalirika kwa makinawo.

Kukhazikitsa ndikosavuta

Mosiyana ndi makina apakompyuta, kukhazikitsa kwa PLC sikufuna chipinda chapadera cha kompyuta kapena njira zodzitetezera zolimba.

Kukweza liwiro

Popeza kulamulira kwa PLC kumachitika kudzera mu kulamulira pulogalamu, sikungafanane ndi kulamulira kwa logic yolumikizirana malinga ndi kudalirika kapena liwiro logwirira ntchito. Chifukwa chake, makina a PLC adzawonjezera liwiro la makina anu pogwiritsa ntchito zolowetsa zanzeru komanso zomveka.

Yankho lotsika mtengo

Machitidwe a logic ozikidwa pa relay, omwe ankagwiritsidwa ntchito kale, ndi okwera mtengo kwambiri pakapita nthawi. Owongolera logic okonzedwa adapangidwa kuti alowe m'malo mwa machitidwe owongolera ozikidwa pa relay.

Mtengo wa PLC ndi wofanana ndi ndalama zomwe zimayikidwa kamodzi kokha, ndipo ndalama zomwe zimasungidwa pamakina ogwiritsira ntchito ma relay, makamaka pankhani ya nthawi yothetsa mavuto, maola a mainjiniya, ndi ndalama zoyikira ndi kukonza, ndi zazikulu.

Ubale wa makina a PLC ndi makampani opangira ma phukusi

Monga mukudziwa kale, makina a PLC amayendetsa makina opakira; popanda makina opakira okha, makina opakira amatha kupereka zambiri zokha.

PLC imagwiritsidwa ntchito kwambiri mu bizinesi yolongedza zinthu padziko lonse lapansi. Kusavuta komwe mainjiniya angagwire ntchito ndi chimodzi mwa zabwino zake zambiri. Ngakhale kuti makina owongolera a PLC akhalapo kwa zaka zambiri, mbadwo wamakono umapangidwa pogwiritsa ntchito ukadaulo wamakono. Chitsanzo cha makina omwe amagwiritsa ntchito mtundu uwu wa makina owongolera ndi makina olongedza zinthu okhazikika. Kuphatikiza makina owongolera a PLC ndikuwonjezera magwiridwe antchito ake ndi chinthu chofunikira kwambiri kwa opanga makina ambiri olongedza zinthu.

Chifukwa chiyani opanga makina opakira amagwiritsa ntchito makina a PLC?

Opanga makina ambiri opaka ma CD amamanga makina awo mothandizidwa ndi makina a PLC pazifukwa zambiri. Choyamba, imabweretsa makina odzipangira okha ku fakitale ya kasitomala, zomwe zimapulumutsa maola ogwira ntchito, nthawi, zinthu zopangira, ndi khama.

Kachiwiri, zimawonjezera mphamvu zanu, ndipo mumakhala ndi zinthu zambiri zomwe zili pafupi, zokonzeka kutumizidwa pakapita nthawi yochepa.

Pomaliza, sizokwera mtengo kwambiri, ndipo munthu wamalonda watsopano angagule mosavuta makina opakira zinthu okhala ndi PLC yomangidwa mkati.

Ntchito zina za makina a PLC

Makampani osiyanasiyana monga a zitsulo ndi magalimoto, makampani opanga magalimoto ndi mankhwala, ndi gawo lamagetsi onse amagwiritsa ntchito ma PLC pazifukwa zosiyanasiyana. Kuthandiza kwa ma PLC kumakula kwambiri pamene ukadaulo womwe akugwiritsa ntchito ukupitilira.

PLC imagwiritsidwanso ntchito mumakampani opanga mapulasitiki kuwongolera kupanga jakisoni ndi makina owongolera makina owononga, kudyetsa silo, ndi njira zina.

Pomaliza, minda ina yomwe imagwiritsa ntchito makina a PLC ikuphatikizapo koma sikuti ndi yokhayo:

· Makampani opanga magalasi

· Zomera za simenti

· Makampani opanga mapepala

Mapeto

Dongosolo la PLC limagwiritsa ntchito makina anu opakira ndikukupatsani mphamvu zophunzitsira zotsatira zomwe mukufuna mosavuta. Masiku ano, opanga makina opakira makamaka amayang'ana kwambiri kukhazikitsa PLC mumakina awo opakira. Kuphatikiza apo, PLC imabweretsa zabwino zambiri pazida zanu zopakira ndipo imagwiritsa ntchito njira yokhayokha pomwe imachepetsa ndalama zogwirira ntchito.

Mukuganiza bwanji za makina a PLC okhudza makampani opanga ma CD? Kodi akufunikanso kusintha?

Pomaliza, Smart Weigh ingapereke makina opakira okhala ndi PLC. Ndemanga kuchokera kwa makasitomala athu komanso mbiri yathu pamsika zingakuthandizeni kudziwa mtundu wa zinthu zathu. Mwachitsanzo, makina athu opakira zinthu zolemera akupangitsa moyo wa eni mafakitale ambiri kukhala wosavuta komanso wosavuta. Mutha kulankhula nafe kapena kupempha mtengo WAULERE tsopano. Zikomo chifukwa cha Kuwerenga!
