Xov xwm

Ib tug conical twin ntsia hlau chim tuav ob tapered screws ib sab ntawm ib sab nyob rau hauv ib lub thoob uas nws bores nqaim los ntawm pub kawg mus rau qhov tuag. Tus taper ntawd yog tus tsim tag nrho. It gives a large intake for low-density powder, a compression that builds gradually instead of abruptly, and rising pressure toward a short discharge. Qhov tshwm sim yog maj mam compression, maj mam shearing, thiab muaj zog conveying, uas yog raws nraim li cas shear-sensitive thiab kub-rhiab cov ntaub ntawv zoo li nruj PVC xav tau.

Ib tug sib npaug ntxaib ntsia hlau chim tuav ob lub qhov taub ntawm qhov ntev ntawm ib sab ntawm ib sab hauv daim duab-yim bore. Cov ntsia hlau tig ua ke thiab thawb cov khoom mus rau pem hauv ntej los ntawm kev ntxiab nws ntawm lub davhlau, tsis yog rub nws mus rau ntawm phab ntsa raws li ib qho ntsia hlau ua. Ob txoj kev tsim qauv txiav txim siab seb lub tshuab tuaj yeem ua li cas: kev sib hloov kev taw qhia (co-rotating lossis counter-rotating) thiab qhov tob npaum li cas ntawm cov ntsia hlau mesh (tag nrho, ib nrab, lossis tsis tag nrho). Tau txais ob txoj cai thiab tib cov khoom siv sib txuas, qhov cua, lossis extrudes tawv PVC.
