ʻEkolu mau wili paumaʻo ia ka papa nui loa o nā pauma wili he nui i ka lawelawe i kēia lā. Hoʻohana ʻia lākou i nā kaʻina hana hoʻomaʻemaʻe no nā huahana viscous wela kiʻekiʻe e like me ka asphalt, lalo o ka hale kiaʻi a me nā aila wahie koena.
Hoʻohana pinepine ʻia ʻekolu mau ʻuala no:
mīkini lubrication
nā mea hoʻokiʻekiʻe hydraulic
wahie aila lawe a me ka puhi ahi lawelawe
hoʻohana ʻana i nā mīkini hydraulic

ʻO ʻekolu-Screw Pump kahi pauma hoʻoneʻe maikaʻi, a loaʻa iā ia nā mea maikaʻi loa e like me:
ʻano maʻalahi, ka leo liʻiliʻi, ʻae ʻia e hoʻololi i ka wikiwiki kiʻekiʻe, kūpaʻa a me ka hana kiʻekiʻe. a hoʻopaʻa iā ia i loko o ka lua meshing, a laila hoʻokuʻu iā ia i ke awa hoʻokuʻu ʻana ma ke kuhikuhi axial o nā wili i ka wikiwiki like, a hoʻokumu i ke kaomi paʻa ma ke awa hoʻokuʻu.

ʻO ka 3QGB moʻo wela-mālama kiʻekiʻe-viscositybitumen ekolu-screw pumpshoʻomohala ʻia e Sinoroader ma hope o nā makahiki he nui o ka noiʻi e hoʻopaʻa i ka hui ʻana ma waena o ka wili a me ka pauka pahū, a ma waena o ka hoʻokele kaʻa a me ka hoʻokele ʻana i hoʻokumu ʻia ma luna o ka pauma ʻekolu-screw, i mea e ʻike ai i ka lawe ʻana a me ka media kiʻekiʻe-kiʻekiʻe. Hoʻohana nui ʻia ʻo Sinoroader bitumen 3-screw pumps no ka mea kanu hui asphalt. Hiki ke hoʻolālā ʻia e like me ke kūlana o ka mea kūʻai aku, Stainless steel gear pump, Loaʻa iā ia kahi koho piha o nā sliding pump. ʻO ka pauma insulation viscosity kiʻekiʻe, Paʻa ka pauma koena, ola lōʻihi, nani ke ʻano.
