| Screw pump is a single-screwransfer pump. Its maiwo*ng parts includehe screw of ecceric helicoid(calledotor) andhe screw bush with a double-line helicoid oits inner surface(called stator). Its wo*ng principle goes likehis: whethe electric motor driveshe pump shaftotate,he screwotates around its owaxes oone hand andolls alonghe inner surface ofhe bush othe other,hus forming a seal cavity ithe pump. Whethe screwotates a cycle,he liquids ithe seal cavity will advance a screw pitch forward. Withhe cotinuous drive ofhe screw,he liquids will press from a seal cavityo another cavity ia spiral manner uil iis pressed ouofhe pump body finally. | |
| Screw pump is aewype of machinery forhe liquidransfer. Iboasts such advaages as simple structure, safe andeliable operation, easy maienance, cotinuous and uniform liquid discharge and stable pressure. The meal parts cotacting materials of our underflow pump all adoptop-grade stainless acid-proof steel andhe shafmaterial is 2Cr13. The bush adoptsotoxicubber witho peculiar smell. Its wo*ngemperature careach upo 100 degree celsius. Icabe used forheransfer of coosive media like foodstuff sluy, solutioor suspensiocotaining solid grains orubber blocks with a viscosity of 10000Pa.S. Iis widely applied isuch industrial sectors as food, meallurgy, construction, pharmacy and chemical industry etc. | |
