Kulemera kopanda kulemera: mfundo ndi njira yowerengera ya multihead weigher

Wolemba: Smartweigh-Multihead Weighter

Mu pepala ili, mfundo ndi njira yotsimikizira za metrological ya multihead weigher imafotokozedwa mwatsatanetsatane kuchokera kuzinthu zomwe zimapangidwira komanso kapangidwe kake. Multihead weigher ndi makina odyetsera mosalekeza omwe ali ndi ntchito yotsimikizira za metrological. Zapangidwa kutengera mfundo yoyendetsera kuwonongeka kwa ukonde pakugwira ntchito, ndipo imagwiritsidwa ntchito kwambiri pamakina ophatikizira odziwikiratu popanga. Keywords: multihead weigher mfundo yotsimikizira za metrological Pakupanga kaboni wabizinesi, makina ojambulira odziwikiratu ndi ntchito yovuta kwambiri komanso pulogalamu yotsimikizira ma metrological system, yomwe ndi yovulaza kwambiri pamtengo ndi index ya carbon anodizing kupanga. Amakhala ndi choyezera chamitundu yambiri ndi masikelo a lamba wamagetsi a 4 (tchulani dzina).

Kutengera kuphunzira movutikira, zochitika zothandiza komanso kafukufuku wasayansi wa oyezera mitu itatu, mkonzi ali ndi chidziwitso chapamwamba komanso kumvetsetsa kwa woyezera mitu yambiri. Apa, fungulo ndikuchita mawu oyambira osavuta komanso atsatanetsatane amisiri yoyambira ndi njira zowerengera za multihead weigher. Gawani nawo anyamata. 1. Kapangidwe kakapangidwe Kapangidwe kakapangidwe ka multihead weigher nthawi zambiri imakhala ndi magawo ofunikira monga chipata chosungira madzi odyetserako, silo yoyezera, chipangizo chokokera, zida zodyetsera, chimango cha khadi lamawu, sensa yolemetsa ndi zida zotsimikizira muyeso. 1. Chipata chosungira madzi Chipata chosungira madzi odyetsera chimagwiritsidwa ntchito kudyetsera hopper yoyezera. Ma valve a zipata, agulugufe, ma valve a zipata, ndi zina zambiri amagwiritsidwa ntchito. Nthawi zambiri, zomwe zimadetsa nkhawa kwambiri ndikusindikiza kwake, kuthekera kwa kusintha kwamagetsi, komanso kudyetsa mwachangu komanso kosalala. magawo a magwiridwe antchito.

2. Silo yoyezera Silo ndi sikelo yoyezera nkhokwe. Kusankhidwa kwa zinthu zopangira kuyenera kuganizira kukana kwa dzimbiri komanso kukana kwa alkali. Gawo lonse loyezera liyenera kukhala pafupifupi 10%. 3. Chipangizo chogwedeza Chida chogwedeza chimagwiritsidwa ntchito makamaka kuthandizira kutsanulira kwa zipangizo ndi kusayenda bwino. Nthawi zambiri amapangidwa ndi injini yosavuta yoyendetsa ya makina othyola mkono okhala ndi tsamba lozungulira kapena spike. Malingana ndi kusinthasintha kwa mkono wosweka, ndizosavuta kuwonekera. Zida zopangira ma arching ndi makoswe zimatha kugwetsedwa bwino polowera ndi potuluka. 1 Kudyetsa chipata chosungira madzi 2. 3. Sensa yoyezera 4 rack card rack 5. Chipangizo chosakaniza 6 Zipangizo zodyetsera 4. Zipangizo zodyetserako chakudya Chida chodyera chimagwiritsidwa ntchito potulutsa ulusi wopangira zida zoyezera. Malinga ndi mawonekedwe a zida zomwe ziyenera kunyamulidwa komanso momwe chilengedwe chimagwirira ntchito, ma conveyors, ma impeller feeders, Feeder, feeder lamba.

Mu ntchito zambiri, wononga conveyor ndi bwino kuposa chatsekedwa zida zodyera. Sizingatheke kunyamula zipangizo mofanana, komanso kupewa kuwuluka ndi kuphulika kwa ufa wa zipangizo. 5. Phokoso la makadi omveka Chingwe cha khadi la mawu ndi malo othandizira makina ndi zipangizo zina, ndipo chojambula cholemera chimayikidwa pamenepo. 6. Sensor yolemera Sensa yolemetsa ndiye chigawo chofunikira cholemera cha multihead weigher, ndipo cholimba cholimba chapamwamba chotsutsana ndi chowunikira chimagwiritsidwa ntchito kwambiri, chomwe chimasintha chizindikiro cha data kulemera kwa ukonde wa zopangira kukhala chizindikiro chamagetsi kuti chituluke.

7. Zida zowongolera zotsimikizira za metrological Metrology verification control zida zimapangidwa ndi woyimba wanzeru kwambiri wamitundu yambiri komanso makina owongolera okha, omwe amagwiritsidwa ntchito poyang'anira ndi kutsimikizira kwa metrological kuthamanga kwa chakudya, kuchuluka kwamayendedwe, ndi zina zambiri. Madoko olowera ndi ma feed a choyezera chambiri amayenera kugwiritsa ntchito zolumikizira zofewa zoletsa kuipitsidwa ndi mpweya kuti zitsimikizire kuti kulumikizana pakati pa chosungiramo chosungira ndi zida zotsatila sikulepheretsa kuyeza kwake. Silo yolemera ya multihead weigher ndi chipangizo chodyera chosinthika chomwe chimayikidwa pansi pake chili pa sensa yolemetsa yomwe imayikidwa pa rack card rack.

2. Mfundo 1. Mfundo Yaikulu Monga momwe zasonyezedwera pachithunzichi, woyezera mitu yambiri amamaliza kutsimikizira kwa metrological molingana ndi mfundo yoyendetsera kuwonongeka kwa ukonde panthawi ya ntchito. Choyamba, kuyeza zida zodyetserako ndi silo yoyezera, yerekezerani liwiro lenileni la kudyetsa ndi liwiro loperekera chakudya malinga ndi kuwonongeka kwa kulemera kwa ukonde pa nthawi ya unit, ndiyeno wongolerani zida zodyetserako kuti liwiro la kudyetserako likwaniritsidwe molondola. kuyambira pachiyambi mpaka kumapeto. , Munthawi yonse yodyetsera kwa nthawi yochepa, zida zodyera zimadalira mphamvu zopangira zizindikiro zowonongeka zomwe zimasungidwa pakati pa ntchitoyo mogwirizana ndi mfundo yaikulu ya mphamvu. Katundu wa spectrum plan 2. Njira yonse yoyezera Kulemera kwa ukonde wa zopangira mu silo yoyezera kumasinthidwa kukhala chizindikiro chamagetsi molingana ndi sensa yolemera ndi kutumizidwa ku multihead weigher dial. Kuyimba kwa multihead weigher kudzachita zowerengeka zolemera zazinthu zopangira komanso zokhazikitsidwa kale zam'mwamba ndi zotsika za ukonde wolemera. Poyerekeza ndi kuzindikira, malinga ndi kuwongolera kwa PLC kwa chipata chosungira madzi, kudyetsa mu silo yoyezera kumasokonekera.

Kuphatikiza apo, kuyimba kwa multihead weigher kumayerekeza liwiro la kudyetsa komwe kumayezedwa (kutulutsa kwathunthu) ndi liwiro lokhazikitsidwa kale, ndipo amagwiritsa ntchito kusintha kwa PID kuti aziwongolera zida zodyetserako, kuti liwiro lenileni la kudyetsa litsatire molondola mtengo wokhazikitsidwa kale. Pamene chipata cha madzi odyetsera chimatsegulidwa kuti chilowetse zinthu muzitsulo zoyezera, chizindikiro cha deta chimagwiritsidwa ntchito kutseka liwiro la kudyetsa, ndipo kudyetsa kwa volumetric kumachitika. Kuyimba kwa multihead weigher kumawonetsa zidziwitso za liwiro la kudyetsa komanso kulemera kwazinthu zonse zomwe zatulutsidwa. 3. Kuwerengera liwiro la kudyetsa Liwiro la kudyetsa la multihead weigher (kutuluka kwathunthu kwa zinthu zotsitsa) ndi kuwonongeka kwa mtengo wa ukonde pa nthawi ya unit. Mtengo wowonongeka dt ndiyeso yolondola ya nthawi yozungulira.

5. Kutsiliza M'makina ena osiyanasiyana amagetsi ndi zida, nthawi zambiri chifukwa cholumikizana ndi zida zopangira, kusintha kwa kutentha kwa sensor yolemetsa kumapangitsa kuti kulemera kwa tare kusinthe, komwe kumabweretsa kuchepetsa kulondola kwa pulogalamu yamapulogalamu, koma multihead weigher amachotsa zophophonya zotere, sikophweka Kutentha mosinthana kuchepetsa masekeli mwatsatanetsatane. Chifukwa chake ndi chophweka kwambiri, kuyeza kwa liwiro la chakudya cha multihead weigher kumatengera kusiyana kwa kulemera kwa ukonde osati kulemera kwa ukonde, kotero kuti multihead weigher ali ndi chiyembekezo chogwiritsa ntchito pulogalamu ya fibrous raw material transportation system.
