Imibuzo ejwayelekile ukubuzwa
Ingabe ama-parallel screw extruder ahlala ezungeza?
Cha. I-Parallel ichaza i-screw-axis geometry, kuyilapho i-co-rotation kanye ne-counter-rotation ichaza ukunyakaza. Cacisa zombili izinkambu uma uqhathanisa okokusebenza. Kulo msebenzi wokukhetha we-PVC, ukucushwa okufanelekile kanye nomsebenzi wokukhipha okuqondile kufanele kusungulwe ngaphambi kokusebenzisa umthamo, ukuxubana noma izimangalo zamandla ezivela kolunye uhlobo lomshini onamawele amabili.
Ingabe i-conical twin screw extruder ihlala ingcono ku-PVC?
Cha. Ukwakhiwa kwe-PVC kanye nemfuneko yomkhiqizo ayikhethi i-geometry ngokwayo. Qhathanisa ukucushwa okuhlongozwayo okuhambisanayo nokuhambisanayo ngaphansi kwemibandela yokudla okuvunyelwene ngayo, ikhwalithi kanye nezimo zokukhiqiza. Ngokushintshwa, umshini ofakiwe nezixhumi ezibonakalayo ezigunyaziwe zivimbela ukukhetha ngaphambi kokuba ukuqhathanisa kwenqubo kugunyaze izakhiwo ezihlukile.
Imuphi umklamo osebenzisa amandla amancane ngekhilogremu ngayinye?
Ilebula yejometri ayitholi impendulo. Linganisa amandla nesisindo somkhiqizo owamukelwe ngesikhathi esifanayo, usebenzisa umngcele wempahla eshiwo. Qhathanisa izindawo zokusebenza ezidingekayo kushejuli yokukhiqiza. Umshini ungaletha i-kg/h eyamukeleke kakhudlwana kuyilapho usebenzisa i-kWh eyengeziwe ngekhilogremu eyamukelwe ngaleso sikhathi.
Ingabe i-conical screw kanye ne-barrel ingakwazi esikhundleni sesethi ehambisanayo?
