Twin-screw pump can be divided into two forms: internal bearing and external bearing. The bearing is lubricated by the conveyor in the structure of the built-in bearing. The twin-screw pump with external bearing structure is separated from the bearing by the working chamber. There is a side clearance between the structure of the pump and the screw, and the independently lubricated external bearing allows it to transport various non-lubricating media. In addition, the synchronous gear is adjusted so that the screw does not contact, and half of the output torque is transferred to the driven screw. Like all screw pumps, external bearing twin-screw pumps also have self-priming ability, and most of the pump transport components are double-suction symmetrical layout, which can eliminate the axial force, but also has a large suction.


The advantages of external bearing double screw pump structure greatly broaden the scope of use of twin screw pump, that is, besides conveying lubricating medium, it can also convey a large number of non-lubricating medium, various viscous medium and corrosive (acid, alkali, etc.) and abrasive liquid.
