G Series Screw Pump
The G series single-screw pump main working parts are eccentric
screw (rotor) and fixed bushing (stator). Due to the special
geometry of the two components, a separate sealed cavity is formed,
the medium is uniformly flowed from the axial direction, the
internal flow velocity is low, the volume remains unchanged, and
the pressure is stable, so that eddy current and agitation are not
generated. The output pressure of each pump is 0.6MPa, the head is
60m (clean water), and it is suitable for conveying medium
temperature below 80 °C (special requirements up to 150 °C).
Because the stator is made of a variety of elastic materials, the
pump's transport of high-viscosity fluids and the transport of hard
suspended particulate media or fiber-containing media are not
suitable for general pumping. The flow rate is proportional to the
speed. The transmission can be directly driven by a coupling, or by
a speed-regulating motor, a V-belt, a gearbox, etc. The pump has
few parts, compact structure, small volume and simple maintenance,
and the rotor and the stator are the wearing parts of the pump, and
the structure is simple and easy to assemble and disassemble.
Generally used in:
1. Environmental protection: Industrial sewage, domestic sewage,
and sludge turbid water containing solid particles and short fibers
are especially used in oil-water separator plate and frame filter
press equipment.
2. Shipbuilding industry: round bottom cleaning, oil water, oil
residue, oil sewage and other ring transportation.
3. Petroleum industry: transporting crude oil, a mixture of crude
oil and water, a mixture of coal gas and water, pouring polymers
into the formation, and the like.
4. Medicine, daily: a variety of thick paste, emulsion, various
ointment cosmetics
5. Food canning industry: all kinds of viscous starch, distiller's
grains, grain slag, various sauces, pulp, solid slurry
6. Construction industry: spraying of cement mortar, lime slurry,
paint and paste
7. Mining industry: solid particles, groundwater, and slurry water
in mines
8. Chemical industry: various suspensions, greases, various
colloidal pastes, various adhesives
9. Printing, papermaking: high viscosity ink, wallpaper PVC polymer
paste and various concentrations of pulp, short fiber slurry
10. Industrial boilers, power plants: coal water slurry
transportation
