Jekiseni rakasakara rekuumba screw barrel rinokuyambira isati yakundikana. Tarisa zviratidzo zvishanu:huremu hwepfuti, matinji matema anodzoka mushure mekucheneswa, kukwira kwemota pakubuda kumwe chete, splay kana kuremara kwepamusoro, uye kunonoka kupora sikururu.Chimwe cheizvi chinogona kuva nezvimwe zvikonzero; maviri kana matatu pamwechete, achifamba nenzira isiri iyo kwemavhiki, anongedza akaenzana pane yakasakara sikuruu nedhiramu. Simbisa necaliper usati watsiva.
A screw barrel kashoma kukundikana zvese kamwechete. Iyo clearance pakati pe screw ne barrel inovhura zvishoma nezvishoma, uye nguva refu chero chinhu chisati chaputsika, gaka iro rinoratidza sematambudziko madiki pazvikamu zvaunogadzira. Dzidza kuaverenga nekukurumidza uye unogona kuronga kutsiva pane kuita kune kumisa mutsara.
Heano zviratidzo zvishanu zvatinoudza vatengi kuti vatarise, uye maitiro ekuzivisa kupfeka kubva kune zvimwe zvinhu zvinokonzeresa zviratidzo zvakafanana.
Sei Bhari Yakasakara Inoratidza Isati Yakundikana
Iyo screw uye dhiramu inoshanda nekubata kwakasimba clearance pakati pazvo, kazhinji chidimbu chemirimita. Iyo gap yakasimba ndiyo inobvumira screw kuvaka kudzvanywa uye mita pfuti inowirirana.
Sezvinoita abrasive kana corrosive material inopfeka screw flights nebarrel bore, gwapa rinowedzera. Melt inotanga kutsvedza kumashure pamusoro pendege pane kuenda kumberi. Hapana chinotaridzika chakatyoka, asi basa rega rega rinoitwa nemuchina rinoita zvishoma kuenderana. Zviratidzo zvishanu pazasi ishanduro dzese dzedambudziko rimwe chete riripo: kurasika mvumo.
1. Shot Weight Drifts
Ichi chinowanzova chiratidzo chekutanga, uye chakavimbika zvikuru. Kana iyo clearance yavhurika, nyungudika inovuza neshure kupfuura screw tip uye isingadzoke valve panguva yejekiseni. Huremu hwepfuti hwakaramba huchidzikama kwemakore hunotanga kudzungaira, uye zvikamu zvaimbofanana zvino zvinosiyana kubva kutenderera kuenda kutenderera.
Usati watsoropodza bhodhoro, bvisa valve isina kudzoka. Cheki mhete yakasakara inoburitsa huremu hwakafanana hwepfuti, uye igadziriso yakachipa. Kana vharuvhu itsva isingadzorere kuenderana, iyo clearance pachayo yakazaruka.
2. Mavara Matema Anoramba Achidzoka
Wese mouder anowana pano neapo dema diki. Chiratidzo chenyevero ndipo pavanodzoka mushure mekuchenesa uye kuchenesa.
Yakasakara clearance inogadzira nzvimbo dzakafa apo firimu rakatetepa rekunyunguduka rinonamatira kumadziro edhiramu pane kuenda kumberi. Firimu irori rinogara richipisa, rinodzikisira, uye nguva nenguva rinoputika mupfuti sechinhu chitema kana shava. Chenesa muchina uye zvimedu zvinonyangarika kweawa, wozodzoka, nekuti yakasakara geometry inoteya zvinhu ichiripo.
PaPVC izvi zvinoratidzika nekukurumidza uye zvakanyanya, nekuti yakashatiswa PVC inobvisa uye inoparadza simbi yainogarira, iyo inowedzera kujekerwa mberi. Inoita loop.
3. Motokari Yakatakura Inokwira paKubuda Kumwechete
Tarisa dhiraivha inotakura pane yakagadziriswa screw kumhanya uye kubuda. Kana ichikwira kumusoro kwemavhiki pasina shanduko kuzvinhu kana maitiro, chimwe chinhu chiri kuwedzera kudhonza.
Yakasakara clearance, zvishoma screw misalignment, uye zvakashatiswa kuvaka pandege zvese zvinosimudza mutoro unofanirwa kukunda mota. Pachayo, kukwira kwemota mutoro hakuna kujeka. Yakabatanidzwa nehuremu hwepfuti inodonha kana kuti twunhu tunodzosa, inonongedza screw yakasakara nedhiramu.
4. Splay Marks uye Surface Defects
Splay, silver streaking, uye general surface haze kazhinji zvinoreva gasi kana mwando mukunyungudika. Kana uchinge wabvisa resin yakanyorova uye wasimbisa kuti kuomeswa kwako kuri kushanda, dhiramu rakasakara rinova mufungidziro.
Siruuru isingachaiti mamita zvakachena inosiya kunyungudika kusingaenderani uye inoteya gasi raifanirwa kunge rakagadzirwa. Kuremara kunoratidza pane chikamu chepamusoro. Kana iyo resin imwe chete yaishandiswa kuumba yakachena uye ikozvino splays isina shanduko yemaitiro, iyo screw geometry inogona kunge yadzungaira kunze kweiyo spec.
5. Screw Recovery Inononoka
Kana nguva yekudzoreredza ikakwira uye yotanga kudya mukati mekutenderera kwako, screw haisisiri kuendesa kunyungudika sezvayakaita. Ndege dzakasakara dzinosundidzira zvinhu zvishoma kumberi pane imwe nguva, saka sikururu inoda imwe nguva, kana kumhanya kwakawanda, kuchaja pfuti imwe chete.
Imwe nguva yekuwedzera yekudzoreredza pachayo inogona kungoreva kuti process tweak inofanirwa. Kukwira kwakadzikama kwemavhiki, padivi pechero zviratidzo zviri pamusoro, ndiro rinokuudza kuti kushanda kwayo kwapera.

Mibvunzo Inowanzo bvunzwa
Ndinoziva sei kana screw barrel yangu yasakara?
Tarisa uremu hwepfuti, matinji matema anodzoka mushure mekuchenesa, kukwira kwemota pakubuda kumwe chete, splay kana kuremara kwepamusoro, uye kunonoka kupora. Chero ani anogona kuve nechimwe chikonzero, asi maviri kana matatu pamwe chete, achifamba zvakanyanya mumavhiki, anonongedza screw yakasakara uye mbiya. Simbisa nekuyera kucheneswa uchienzanisa neyekutanga kuvaka kudhirowa.
Chii chinoita kuti uremu hwepfuti huve husina kuenderana?
Zvikonzero zviviri zvikuru: vharafu isingadzoke, kana kuti screw-to-barrel clearance yakasakara ichirega ichinyungudika ichitsvedza kumashure panguva yejekiseni. Tarisa vharuvhu kutanga, nekuti ndiyo yakachipa kugadzirisa. Kana vharuvhu itsva ikasadzoreredza kuenderana, kubvisirwa kwebhari kungangove kwakavhura kushivirira kwakapfuura.
Yakawanda sei clearance zvinoreva kuti screw barrel inoda kutsiviwa?
Sekutonga kwechigunwe, kana radial clearance inosvika kaviri kusvika katatu kubvumidzwa kwekutanga kwekuvaka, kuburitsa uye kunyungudika mhando yakadzikira zvakakwana kururamisa kutsiva kana kuvakazve. Iyo chaiyo nhamba inotsamira screw diameter, saka simbisa uchipesana neyako yekuvaka dhizaini.
Ndinogona kutsiva chete sikuruu ndochengeta dhiramu?
Ehe, kana dhiramu richiri kuyera mukati mekushivirira. Kupfeka kunowanzo kusaenzana, saka zviyera zvese usati wasarudza. Kana screw yakapfekwa asi dhiramu yakanaka, kuvaka patsva kana kutsiva sikuruu chete kunodzoreredza clearance. Kana zvese zvakasakara, zvitsive seti inofananidzwa.
Nei dhiramu rimwe chete richiramba richisakara nekukurumidza?
Kukurumidza kudzokorora kupfeka kazhinji kunoreva kuti kurapwa kwepamusoro hakuenderane nezvinhu. Girazi faibha, mineral fillers, uye corrosive resin inopfeka neyakajairwa nitrided layer nekukurumidza. Kuitsiva neimwe nitrided barrel inodzoreredza iyo imwechete pfupi countdown; iyo inogadzirisa ndeye bimetallic kana corrosion-resistant surface, kwete imwe yakafanana chikamu.
