Mapampu atatu a screwndiye gulu lalikulu kwambiri la mapampu angapo omwe akugwira ntchito masiku ano. Amagwiritsidwanso ntchito poyeretsa zinthu zotentha kwambiri za viscous monga asphalt, vacuum tower bottoms ndi mafuta otsalira.
Mapampu atatu omwe amagwiritsidwa ntchito kwambiri:
makina opangira mafuta
ma elevator a hydraulic
zoyendera mafuta ndi ntchito zoyatsira mafuta
makina opangira ma hydraulic

Pampu Yatatu-Screw ndi mpope wabwino wosamuka, ndipo ili ndi zabwino zambiri monga:
dongosolo losavuta, voliyumu yaying'ono, kuloledwa kuzungulira pa liwiro lalitali, kukhazikika komanso kuchita bwino kwambiri, ndi zina zambiri. Pogwiritsa ntchito mfundo ya screw meshing ndikudalira kulumikizana kwa zomangira zozungulira mu chipika cha mpope, pampu ya screw atatu imayamwa sing'anga yomwe imaperekedwa. ndikuyisindikiza muzitsulo zazitsulo, kenako ndikukankhira ku doko lotayira motsatira njira ya axial ya zomangira pa liwiro la yunifolomu, ndipo imapanga kupanikizika kokhazikika pa doko lotulutsa.

Mndandanda wa 3QGB woteteza kutentha kwambiriphula zopopera zitatuopangidwa ndi Sinoroader patatha zaka zambiri za kafukufuku kukhathamiritsa mgwirizano pakati wononga ndi mpope chipika, ndi pakati pa galimoto wononga ndi wononga wononga yochokera atatu screw mpope, kuti azindikire yobereka og mkulu-kutentha ndi mkulu-kukhuthala TV. Mapampu a sinoroader phula-zikuluzikulu zitatu  amagwiritsidwa ntchito makamaka posakaniza phula. Itha kupangidwa molingana ndi momwe kasitomala alili, pampu yachitsulo chosapanga dzimbiri, Ili ndi mapampu oterera athunthu. Pampu yotchinga yamphamvu kwambiri, Pampu yotsalira ndi yaying'ono, moyo wautali, Maonekedwe okongola.
