Labaran Masana'antu

Don gyare-gyaren nailan mai cike da gilashi, fara da ainihin ƙimar PA da abun ciki na gilashi-gilashi. Nanhaiya ya jera 38CrMoAlA na alluran da aka kashe-da-fusata don ƙarfafa robobi mai ɗauke da fiber gilashin 30%, gami da PA-GF. Shafukan samfurin sa kuma sun bayyana nitriding da nickel-tungsten gami da ƙarfafa gabobin da ke da rauni da ganga. Zaɓi tsarin lissafi da tsarin sama akan ainihin aikin, sannan duba guntun ganga da dunƙule tip ko duba zobe kafin karɓar canji. Dokokina a gefen masana'anta abu ne mai sauƙi: ƙimar taurin ƙima ba ta ceton jumlolin da ba daidai ba, kuma sabon dunƙule ba ya ceto ƙarshen gaba. Sanya duka musaya guda uku akan zane da duk halaye guda uku a cikin shirin gwaji.

Zaɓi dunƙule gyare-gyaren allura ba zato ba tsammani a matsayin wurin farawa don kayan kristal ko Semi-crystalline waɗanda ke amfana daga saurin matsawa da narkewa. Nanhaiya ya lissafa PE, PP, PA, POM da PTFE. Sashin matsawa na mutant ya mamaye kusan kashi 5% zuwa 15% na jimlar tsayin dunƙule. Zaɓi dunƙule a hankali a matsayin mafari don amorphous ko kayan zafin zafi waɗanda ke buƙatar sauƙaƙan sauyi. Nanhaiya ya lissafa PVC, PS, PC, PSU da ABS. Sashin matsawa a hankali yana ɗaukar kashi 40% zuwa 60% na jimlar tsayinsa, tare da kusan 50% an kwatanta shi azaman na yau da kullun. Tabbatar da kowane zaɓi tare da ainihin maki, mai filler, danshi, amfani da harbi, lokacin dawowa, yanayin narkewa da karɓan sassa.

Ƙayyade PE ko PP babban dunƙule guda ɗaya ta ainihin kayan, fitarwa mai siyarwa, samfuri da mutu, saurin ɗigon ƙasa, taga narke-zazzabi, matsa lamba, injin mota da aikin akwatin gear, ƙarfin sanyaya, yanayin lalacewa da hanyar karɓa. Kada ku saya daga diamita da matsakaicin rpm kadai. Nanhaiya ta buga nau'ikan dunƙule guda tara daga NHY20 zuwa NHY150, tare da fitowar fitarwa daga 3 zuwa 1,300 kg/h da saurin gudu daga 10 zuwa 150 rpm a cikin iyali. Babban samfurinsa na PE da PP yana amfani da ingantacciyar juzu'i na juzu'i, babban akwati mai ƙarfi, ganga mai ramukan abinci na musamman da ginin gami mai jurewa. Juya kowane maƙasudin aikin zuwa madaidaicin wurin gwaji ta amfani da resin mai suna, mutu, taga mai inganci da iyakar ma'aunin lantarki.

Don ƙayyade dunƙule guda ɗaya mai jure lalacewa, aika madaidaicin guduro da daraja, filler ko nau'in fiber da kashi, abun da aka sake yin fa'ida, gurɓatawa, nau'in ciyarwa, danshi, yanayin gwajin MFR ko MVR, fitarwa da ake buƙata, saurin dunƙule, nauyin motar, narke matsa lamba, zazzabi, lokutan aiki da taswirar lalacewa na yanzu. Sannan zaɓi saman ta wurin lalacewa. Nanhaiya yana ba da 38CrMoAlA, SACM645, 42CrMo da ƙananan ƙarfe-karfe, tare da zurfin ion nitriding, kariya ta PTA akan saman jirgin sama da tarnaƙi, da tungsten carbide da zaɓuɓɓukan saman tushen nickel. Dole ne a bincika dunƙule da aka tsara tare da ganga mai ɗaurin aure, saboda sabon ƙasa mai wuya ba zai iya gyara ƙaƙƙarfan ƙarami ko mara kyau ba.

Don siyan akwatin gear filastik extruder, ƙididdige ƙarfin motar da ƙimar ƙimar da ake buƙata, kewayon sauri-gudun da ake buƙata, ci gaba da aikin jujjuyawar juzu'i, adadin dunƙule da juyawa, kayan aiki da fitarwa, sa'o'in aiki, shigarwa da mu'amalar shaft na fitarwa, matsayi mai hawa, matsar nauyi, lubrication, sanyaya da gwajin karɓa. Ƙarfin mota kaɗai ba ƙayyadaddun akwatin gear ba ne. Layuka biyu masu mota iri ɗaya na iya ƙaddamar da juzu'i daban-daban, zafi, girgiza, aiki tare da ayyukan ɗaukar nauyi. Zane-zanen da aka sanya hannu ya kamata ya gano shingen gefen mota da shinge-gefe-gefe, saurin su, kwatancen juyawa, rabo, hawan datums da kowane haɗin da ake buƙata don shigarwa.

Don siyan flange na ganga mai extruder, aika da zane mai sarrafawa wanda ke gano gungu, diamita na waje, kauri, rajistar gano wuri, ƙirar ƙusa, fuskar rufewa, abu, jiyya na sama da sassan mating. Ƙara ainihin yanayin zafin jiki da tushen matsa lamba, samfurin extruder ko mutu-head, yawa da buƙatun dubawa. Kada ka yi oda flange na inji na al'ada daga kalmomin "ANSI," "DIN," "JIS" ko "PN16" kadai. Waɗancan nassoshi za su iya ayyana madaidaicin flange bututu kawai lokacin da aka bayyana cikakken daidaitaccen tsari da tushen sabis. Haɗin extruder yawanci yana buƙatar zane na mu'ujiza na kansa, koda lokacin da gefe ɗaya ya bi sanannen ƙirar flange.
