Chitoliro cha PVC, bolodi ndi pepala zonse zimayendera pa mbiya yamapasa yamapasa, koma yolondola imasiyana ndi mawonekedwe a screw, zotuluka ndipo - koposa zonse - chitetezo chovala. Chitoliro chimakonda kutulutsa kokhazikika komanso kuthamanga; bolodi la thovu ndi pepala zimayendetsa zodzaza kwambiri ndipo zimafunikira kukana kwambiri abrasion. Pezani kukula kuti mufanane ndi extruder yanu, kenako sankhani nitrided kapena bimetallic kutengera kuchuluka kwa zodzaza fomu yanu.

Makina opangira ma conical twin screw extruder ndi makina owongolera a PVC okhala ndi zomangira ziwiri zopindika - zotambalala kumapeto kwa chakudya, zopapatiza kumapeto kwake. The conical geometry imapereka makokedwe apamwamba komanso kukanikizana kolimba muutali wophatikizika, ndikupangitsa kukhala makina okhazikika a chitoliro cha PVC, mbiri, bolodi ndi kupanga WPC.

Chipilala chopindika ndi mbiya yopindika, yokhala ndi mapasa momwe zomangira ziwiri zozungulira zimazungulira mkati mwa mbiya yofananira. The tapered geometry amapereka chakudya amphamvu ndi psinjika mkulu mu utali wautali, ndichifukwa chake conical mapasa wononga ndi mbiya ndi muyezo kusankha PVC chitoliro, mbiri, pepala ndi WPC extrusion.

Mgolo wa jekeseni wonyezimira umakuchenjezani usanalephere. Yang'anani zizindikiro zisanu: kulemera kwa kuwombera, madontho akuda omwe amabwerera pambuyo poyeretsedwa, kukwera kwa injini pamtundu womwewo, splay kapena zowonongeka pamwamba, ndi kuchira pang'onopang'ono. Chimodzi mwa izi chikhoza kukhala ndi zifukwa zina; awiri kapena atatu palimodzi, kutsata njira yolakwika kwa milungu ingapo, kuloza molunjika pa screw ndi mbiya. Tsimikizirani ndi caliper musanalowe m'malo.

The screw barrel ndiye pakatikati pa makina anu opangira jakisoni. Imasungunula pulasitiki yanu, kuisakaniza, ndikukankhira mu nkhungu - kuzungulira pambuyo pa kuzungulira, kwa zaka. Zikalakwika pakugwiritsa ntchito kwanu, mumaziwona paliponse: kulemera kwa kuwombera kosagwirizana, zofooka zapamtunda, madontho akuda, ndi kukwera kwa zinyalala. Bukhuli likukhudza mfundo iliyonse yosankha kuti muthe kuyikonza nthawi yoyamba.

Chiŵerengero cha jekeseni wa L/D ndi kutalika kwa ntchito kugawidwa ndi screw diameter, ndipo zomangira zambiri zimayendera 18:1 mpaka 25:1. Izi ndi zomwe palibe pepala lakukuuzani: simungathe kusintha L/D pamakina omwe muli nawo kale. Kutalika kumakhazikitsidwa ndi mbiya. Zomwe mungasinthe ndi screw diameter, ndipo mu mbiya yokhazikika yomwe kusankha kumodzi kumasuntha L/D, kuwombera mphamvu, ndi kuthamanga kwa jekeseni palimodzi, mbali zosiyana. Chophimba chaching'ono chimapereka L/D yokwezeka, kuwomberako pang'ono, komanso kupanikizika kwambiri. Fananizani malonda ndi utomoni wanu ndi gawo lanu, ndipo mafunso ambiri a L/D amadziyankha okha.
