中文版Positive Displacement Pump
G Progressive Cavity Mono Screw Pump
Summary
The single screw pump is an internal meshing closed screw pump. As the rotor type positive displacement pump(the Archimedes' screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle. It has strong adaptability to the medium,which can transport various flowable medium , as well as highly viscous, fibrous, medium containing hard suspended or solid particles.

Advantage
Comparison of the screw pump and other pumps:
1. screw pump does not need to install a valve, stable flow and pressure pulsation when compared with the centrifugal pump,
2. The screw pump has strong self-priming ability and strong suction height: 5m when compared with the general pump
3. the screw pump can transport various mixed impurities containing gas, solid particles (Max.50mm) or fibers without destroying it , and can also transport various corrosive substances when compared with the diaphragm pump
4. the screw pump can transport high-viscosity substances， maximum viscosity of 200,000cps and water containing rate of 50% depend on materiality when compared with the gear oil pump
5. screw pump can be used for pharmaceutical filling and metering when compared with the plunger pump, diaphragm pump and gear pump
6. Others, bearings are placed externally, fluids are not contaminated.flow direction can be changed and reversed running. Sealing is set on suction side, maintenance is easy.

Applications
As a rotor pump, the flow rate can be adjusted by changing the speed according to the requirements by reducer. The following ranges and industries are widely used:
|
1.Environmental protection: |
industrial sewage, domestic sewage, sludge anddirty water containing solid particles and short fibers, especially suitable for oil-water separators, plate and frame filter presses and other equipment |
|
2.Shipbuilding industry : |
wheel bottom cleaning, oily water, oil residue, oily sewage and other media |
|
3. Petroleum industry: |
crude oil, crude oil and water mixtures, coal field gas and water mixtures, injecting polymers into formations, etc., reducinga lot of cost |
|
4. Medicine and daily chemicals: |
viscous pastes, emulsions, and various ointments and cosmetics |
|
5. Food canning industry: |
viscous starch, cooking oil, honey, syrup, fruit pulp, butter, minced fish and minced meat and its leftovers |
|
6. Brewing industry: |
alcohol viscous slurries, thick liquor tanks, grain product residues, various sauces, slurries and mucus containing massive solids, etc.; |
|
7. Construction industry: |
spraying and conveying of cement mortar, lime mortar, paint and other pastes; |
|
8. Mining industry: |
the groundwater and sludge water containing solid particles in the mine are discharged to the ground; |
|
