is the use of screw rotation to suction fluid. Figure 3 Screw Pump, said the cutaway view. The figure, the middle screw to screw the initiative, motivated by the original rotation, both sides of the screw as the screw driven, with the initiative to make counter-rotating screw. Active Screw driven screw thread are double-headed screw.

As a result of meshing between the screw and the screw and the cylinder wall lining the close co-ordination in the pump suction and discharge between the export, it will be divided into one or more of the sealed space. With the screw rotation and meshing, which sealed space in the pump suction side are evolving, the inhalation of liquid enclosed in one room, and along the screw axis from the inhalation chamber and continuously push the move to discharge end, will be closed in each room continuous discharge of liquid, like a nut rotation in the thread was constantly pushing forward the case, as this is the basic working principle of Screw Pump.

Screw Pump works by: Screw Pump work, after the liquid is inhaled into the thread with the pump sealed space enclosed by the shell, when the initiative to screw rotates, Screw Pump seal extrusion capacity in the threaded Raising Screw Pump pressure and movement along the axis. As the screw is a constant speed rotation, so the liquid stream flow rate is out of uniform.

Screw Pump is characterized by: Screw Pump loss, economic performance is good. High and uniform pressure, flow uniformity, high speed can be directly associated with the original motivation.

Screw Pump to transport oil, transportation fuel, transport all kinds of oils and polymers used for conveying viscous liquids.

Transport high viscosity medium:

According to the size of the pump can transport different from 37000-200000 cps viscosity of the medium.

Containing particles or fiber media: the particle diameter can be 30mm (not to exceed rotor eccentricity). Fiber length can be 350mm (rather 0.4 rotor pitch). Its content usually ranging from 40% of medium pits, if the medium solids of the powder for subtle shape, the highest content of up to 60% or higher can also transfer.

Requires delivery of the pressure stability, and media do not like to destroy the existing structure, the selection of single-Screw Pump delivery is ideal.

Single Screw Pump – a single thread screw slot in the inner pump gear pump rotation.

Double Screw Pump – mutual engagement by two screw pumps transport liquids.

Multi-Screw Pump – meshing with each other by a number of screw liquid transfer pump.
