Overview
This screw pump can be used to
transport neutral or corrosive
liquids, clean or abrasive liquids,
liquids containing gas or prone to
foaming, and high or low viscosity
liquids, including those with fibers
and solids. It is mainly applied in
industries such as food, textiles,
paper-making, petroleum, chemicals,
alkali and salt production,
shipbuilding, construction, nuclear
industry, metallurgy, and mining.
Working Principle
The single-screw pump is an
internally meshing closed-type screw
pump belonging to the positive
displacement rotor pump category.
Its main working components consist
of a stator with a double-helical
cavity and a single-helical screw
rotor that meshes within the stator
bore. When the input shaft drives
the rotor via a universal joint to
perform planetary rotation around
the stator, the stator-rotor pair
continuously forms closed cavities.
These cavities move axially at a
constant speed with unchanged
volume, conveying the medium from
the suction end through the
stator-rotor pair to the discharge
end. The medium sucked into the
closed cavity flows through the
stator without being agitated or
damaged. Therefore, it can transport
media containing hard abrasive
impurities or solid particles, as
well as viscous liquids.
