G-type single screw pump is a kind of internal meshing closed screw pump, which belongs to the rotor type positive displacement pump. Because this pump has strong adaptability to the medium, stable flow, good suction performance and small pressure pulsation, it can transport various In addition to the flowing medium, it can also transport highly viscous media, media containing hard suspended particles or solid particles, and media containing fibers. It has good adjustment performance, wide range and high efficiency. Therefore, it is used in environmental protection, ships, petroleum, medicine , daily chemicals, food, brewing, construction, mining, chemistry, printing, paper, power plants, boilers and other industries are widely used.

The single screw pump is an internal meshing rotary positive displacement pump. The main working parts are the eccentric screw (rotor) and the fixed bushing (stator), due to the special geometry of the rotor and stator. Several separate sealed chambers are respectively formed, and the operation of the rotor transports the medium in each sealed chamber from the suction end to the extrusion end continuously, at a uniform speed and with a constant volume. Due to these characteristics, the single screw pump is especially suitable for the following conditions;

1. Conveying high viscosity medium;

2. Conveying media containing solid particles or fibers;

3. Continuous, stable pressure and no periodic pressure fluctuations are required;

4. The agitation is required to be small without destroying the inherent structure of the conveyed medium;

5. Low noise.

Scope of application

As a general-purpose pump, the flow rate of the single-screw pump can be changed according to the requirements, the running speed can be high or low, and the outlet pressure can increase with the increase of the pump stages. Scope and industry wide application:

1. Environmental protection: transportation of industrial sewage, domestic sewage, sludge water containing solid particles and short fibers, especially suitable for oil-water separators, plate and frame filter presses and other equipment;

2. Shipbuilding industry: transportation of wheel bottom cleaning, oily water, oil residue, oily sewage and other media;

3. Petroleum industry: transporting crude oil, a mixture of crude oil and water, a mixture of coal gas and water, injecting polymers into the formation, etc., thereby reducing the cost of mechanical oil recovery and coal gas mining, and increasing oil port recovery ;

4. Medicine and daily chemicals: transportation of various viscous slurries, emulsions, and various ointments and cosmetics;

5. Food canning industry: transportation of various viscous starch, cooking oil, honey, syrup, fruit pulp, butter, fish and meat mill and its leftovers;

6. Brewing industry: various fermented viscous slurries, concentrated distiller's grains, grain products, various sauces, slurries and liquids 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;

9. Chemical industry: various suspensions, oils, various colloids, various adhesives;

10. Printing and paper industry: conveying high viscosity ink, PVC polymer plastic paste for wallpaper, pulp of various concentrations, and short fiber pulp.

11. Industrial boilers, power plants: transportation of coal-water slurry.
