Kutanga, sarudza chaiyo yekudziya mudziyo
Kubvisa purasitiki yakamisikidzwa pascuru nemoto kana kugocha ndiyo nzira yakajairika uye inoshanda yezvikamu zvekugadzira epurasitiki, asi murazvo weacetylene haufanirwe kushandiswa kuchenesa sikururu.
Yakarurama uye inoshanda nzira: shandisa blowtorch pakarepo mushure mekunge screw yashandiswa kuchenesa. Nekuti screw ine kupisa panguva yekugadziriswa, kugovera kwekushisa kwescrew kuchiri yunifomu.
Chechipiri, sarudza iyo yakakodzera yekuchenesa mumiririri
Kune akawanda marudzi escrew cleaners (screw cleaning materials) pamusika, mazhinji acho anodhura uye ane mhedzisiro dzakasiyana. Makambani ekugadzira epurasitiki anogona kushandisa masirasi akasiyana kugadzira screw yekuchenesa zvinhu zvinoenderana nekwavo mamiriro ekugadzira.
Chechitatu, sarudza nzira yakarurama yekuchenesa
Nhanho yekutanga yekuchenesa screw ndeye kudzima kuisirwa kwekudya, ndiko kuti, kuvhara chiteshi chekudyisa pazasi pe hopper; Wobva wadzikisa screw speed kusvika 15-25r/min uye chengetedza iyi speed kusvika kunyungudika kuyerera kumberi kwefa kunomira kuyerera. Tembiricha yenzvimbo dzese dzekudziya dzedhiramu inofanira kuiswa pa200 ° C. Pangosvika dhiramu iyi tembiricha, kuchenesa kunotanga.
Zvichienderana neiyo extrusion maitiro (iyo inofa ingangoda kubviswa kuti ideredze njodzi yekumanikidza yakawandisa kumberi kweiyo extruder), kucheneswa kunofanirwa kuitwa nemunhu mumwechete: mushandisi anoona screw kumhanya uye torque kubva pane control panel, uchitarisa extrusion pressure kuti uone kuti system pressure haina kunyanya kukwira. Munguva yese yekuita, screw speed inofanira kuchengetwa mukati me20r / min. Mune maapplication ane low pressure inofa, usabvisa difa rekuchenesa pakutanga. Kana iyo extrusion yakashandurwa zvachose kubva pakugadzirisa resin kuenda kune yekuchenesa resin, kufa kunomiswa uye kubviswa, uye ipapo screw inotangwazve (mukati me10r / min) kubvumira yakasara yekuchenesa resin kubuda kunze.
Chechina, sarudza maturusi ekuchenesa akakodzera
Zvishandiso zvakakodzera uye zvinhu zvekuchenesa zvinofanira kusanganisira: magirovhosi asingadziviriri, magirovhosi, scrapers yemhangura, mabhurashi emhangura, mhangura waya mesh, stearic acid, magetsi emagetsi, vatongi vebhari, jira rekotoni.
Kana iyo resin yekuchenesa yamira kubuda, screw inogona kubviswa kubva pachigadzirwa. Nema screws ane inotonhodza system, bvisa hose line uye swivel connection usati watanga screw extraction device, inogona kusungirirwa kugiya bhokisi. Shandisa screw extraction mudziyo kusundira screw kumberi, uchifumura chinzvimbo che4-5 screws yekuchenesa.
Iyo resin yekuchenesa pane screw inogona kucheneswa nemhangura scraper uye brashi yemhangura. Mushure mekuchenesa resin pane yakafumurwa sikuru yacheneswa, mudziyo unosundirwa kumberi 4-5 screws uchishandisa screw yekubvisa mudziyo uye ramba uchichenesa. Izvi zvakadzokororwa uye pakupedzisira yakawanda ye screw yakasundidzirwa kunze kwedhiramu.
Kana yakawanda yeresin yekuchenesa yabviswa, sasa imwe stearic acid pane screw; Zvadaro shandisa copper wire mesh kuti ubvise zvakasara, uye mushure mekunge screw yese yapukutwa nemhangura waya mesh, shandisa jira redonje pakupukuta kwekupedzisira. Kana iyo screw inoda kuponeswa, mutsetse wegirisi unofanirwa kuiswa kumusoro kudzivirira ngura.
Kuchenesa dhiramu kuri nyore kupfuura kuchenesa screw, asi kunokosha zvakare.
1. Paunenge uchigadzirira kuchenesa bhodhoro, kutonhora kwebhodhoro kunoiswawo pa200 ° C;
2. Kara bhurasho resimbi rakatenderedzwa papombi yekuboorera uye chibooreso chemagetsi muzvishandiso zvekuchenesa, wozoputira bhurasho resimbi nemhangura waya mesh;
3. Usati waisa mudziyo wekuchenesa mubhodhoro, dzvara imwe stearic acid mudhiramu, kana kumwaya stearic acid pamhangura waya mesh yechishandiso chekuchenesa;
4. Mushure mokunge mhangura yemhangura inopinda mubhodhoro, tanga chibooreso chemagetsi kuti uitenderedze, uye uchiita kuti ienderere mberi uye mberi kusvikira ichi mberi uye shure kwekufamba kunenge kusina kupikisa;
5. Mushure mokunge tambo yemhangura yemhangura yabviswa kubva mubhodhoro, shandisa boka remucheka wekotoni kuti udzise nekudzoka mubhodhoro kuti ubvise chero resin yekuchenesa kana mafuta akasara; Mushure mekupukuta kwakawanda kwakadaro-uye-kumashure, kucheneswa kwebhari kwapera. Iyo yakanyatsocheneswa screw uye mbiya yakagadzirira kugadzirwa kunotevera!
