Midziyo yakakodzera yakakosha kugadzira PTFE waya netambo.Parizvino, pane anonyanya marudzi maviri: mechanical type inofambiswa ne screw rod uye hydraulic type inofambiswa ne hydraulic pressure, idzi mbiri mhando imwe neimwe ine zvakanakira nekuipira.
PTFE ipurasitiki inenge yakaoma kugadzirisa, saka michina yakakosha.Kana iwe uchifanira kugadzira MIL-giredhi PTFE extrusion mitsara, senge RG178, RG179, RG316, RG142, G401, RG402, RG405, nezvimwewo, yakakodzera michina yakakosha.Parizvino, kune kunyanya marudzi maviri munyika: mechanical type inotungamirirwa ne screw rod uye hydraulic type inotungamirirwa ne hydraulic pressure;iwo marudzi maviri ePTFE pushers pamusika imwe neimwe ine zvakanakira uye zvayakaipira:
(1) Screw push
Izvi ndizvo zvinonyanya kuzivikanwa.Iyo screw yakakamurwawo kuita siruuru inotsvedza uye bhora sikuruu.Kana iwe uchida kugadzira coaxial tambo, nekuti inotsvedza sikuru ine inouraya yakashata yekudzika-kumhanya kukambaira, kusunda hakuna kugadzikana, uye hakukurudzirwe.Iyo bhora screw haina dambudziko iri, asi nekuti nzvimbo yekubata bhora ishoma, kune dambudziko rakakomba rehupenyu hwekupfeka pasi pekumanikidzwa kukuru.Iyi nzira haikodzeri nzira yekumanikidza kukuru, ndiko kuti, pakugadzira waya, kunyanya kureba kwakakura Mutsara wakaonda-walled uri nani pairi!Nekuda kwekuganhurirwa kwekureba kwe screw uye kurongeka (uye zvimwe zvirambidzo senge mandrels), kureba kwepusher hakuna kureba.Parizvino, yakajairika inoita semamita 1,5!Advantages: Pasi pemamiriro ekudzivisa dambudziko rekukambaira uye high pressure abrasion, screw ine zvakanakira kutapurirana kwakagadzikana uye mutengo wakaderera, iyo ndiyo nzira huru yemidziyo yemumba PTFE parizvino.Iyo yekusundidzira nzira inonyanya kudzika kumusoro, uye mamwe anogadzirwa akachinjika.Kuzvipfupisa nemuromo wakapfava: [Kugadzirwa kwemumba kunogadzirwa, kwakakura, asi nekuti yakavhurika-loop uye isingadzoreki, iyo misimboti uye chaiyo dhizaini dhizaini zvakasakara, zvakanyanya makore 30-40 Chimiro chekare chekare chine zvazvakaipira. yakaderera yekusundira simba (10-20T), kushanda kwakaderera, kunonoka, kupfupika kwekugadzira kureba, uye zvishoma nezvishoma kupfeka kwescrew rod kuchave nekukanganisa kukuru paVSWR.Zvakanakira ndezvokuti mutengo wakaderera.
(2) Hydraulic push
Iyo nzira inomiririrwa neJENNINGS muUnited States inoshandisa mavharuvhu anodzorwa nedhijitari kuti awane chaiyo hydraulic kuyerera kwekutonga kuti iwane yakagadzikana kusunda kumhanya.Nekuti iyo hydraulic nzira inoshandiswa, simba rekusundidzira rakakura kwazvo uye rinogona kusvika padanho rematani zana.Nenzira iyi, waya yakakura yekumanikidza iri nyore kuwana, uye nekuti iyo yakachinjika kusunda inoshandiswa, humburumbira inogona kuitwa yakareba kwazvo (kusvika 108 inches = 2.7 metres), nekuti iyo sintering chikamu inoshandisa kumberi kwe traction fumigation, saka kumhanya. ye extrusion uye sintering nekukurumidza!kugadzirwa kwepamusoro.Zvakaipa: Nekuti nzvimbo haina kuwanikwa, mutengo wemuchina wakakwira!Zvakare, kuchengetedza kweiyo hydraulic pressure zvakare kunonetsa.Kana zvikasaitwa zvakanaka, pachava nedambudziko rekubuda kwemafuta.Ndinovimba kuti vagadziri vemidziyo yemumba vachaita pundutso panyaya iyi.Kuzvipfupisa nemuromo wakapfava: [kune imwe nyika kunonyanya kuve hydraulic, nekuti yakavharwa-loop control inoshandiswa, uye simba re hydraulic rakakura (kusvika ku100T), saka kugona kwekugadzira kwakakwira uye urefu hwekugadzira hwakareba (3-4). nguva), Uye mhando yacho yakagadzikana (senge waya dhayamita fluctuation, VSWR index, nezvimwewo) uye inodzorwa zvizere nekombuta, inova sarudzo yakanaka yekugadzirwa kwemazuva ano!
(3) Electro-hydraulic drive
Iyi ndiyo yakanyanya kucheka-kumucheto tekinoroji parizvino, uye zvakare iri nzira yekuvandudza ye hydraulics.Iyo ine zvakare mabhenefiti ehombe hydraulic thrust uye yakagadzikana kufambisa kweiyo screw rod.Haisati yashandiswa kune PTFE pushers ikozvino, asi yatotanga kushandiswa pane imwe yepamusoro-yekupedzisira mauto ehondo.
