Overview of G - type Stainless Steel Single Screw Pump

The G-type single-screw pump is made of a variety of elastic materials for the stator, so the pump for high viscosity of 80% of the fluid transport and contains a rigid suspension of particulate media or fiber-containing medium transport, the general pump can not do the characteristic. Its flow and speed are proportional to, widely used in food and metallurgy, paper, printing and dyeing, chemical, chemical fertilizer and other industrial sectors to use. Transmission can be used directly drive coupling, or high-speed motor, V-belt, gearbox and other device speed.

G stainless steel single screw pump features

The pump parts less compact, small size, easy maintenance, the rotor and the stator is a single screw pump wearing parts, simple structure, easy assembly and disassembly. It is a new type of pump that works according to the principle of positive displacement. The main working parts are eccentric screw (rotor) and fixed bushing (stator). The use of non-toxic and tasteless edible rubber, the working temperature of up to 120 degrees Celsius, if the use of high temperature 120 degrees Celsius -350 degrees Celsius can contact with the unit. Due to the special geometry of the two parts at the beginning of the formation of a separate sealed cavity. The medium flows through the shaft evenly. The internal flow rate on behalf of the low, the volume remains unchanged. The pressure is stable and therefore the product does not swirl and stir. Each stage of the pump output pressure of 0.6MPa-1.2MPa, head 60m-120m (water), self-priming height is generally more than 3m.

G stainless steel single screw pump applications

Screw pump as a general pump, the flow can be adjusted according to the requirements, the speed can be adjusted, the speed can be high or low, the outlet pressure can be increased with the pump series, each additional level, the pressure increased 0.6MPA, in the following range and Industry widely used; environmental protection: industrial sewage, domestic sewage, solid particles and short fibers containing muddy water transport, especially for oil and water separator, plate and frame filter press and other equipment;

  1. the shipping industry: round low cleaning, oil and water, oil, oil and other sewage media transport;
  2. the oil industry: the transport of crude oil, crude oil and water mixture, coal gas and water mixture, into the formation of polymer and so on, thereby reducing the cost of mechanical recovery, coal mining gas, increased oil recovery;
  3. medicine, cosmetic: viscous pulp, emulsion, all kinds of ointment cosmetics delivery;
  4. food canned industry: a variety of fermented sticky starch, cooking oil, honey, syrup, pulp, cream, fish extravagant meat and its waste delivery
  5. brewing industry: a variety of fermented viscous liquid, concentrated lees, food products slag, all kinds of sauce, pulp and containing fast solid matter, such as mucus;
  6. the construction industry: cement mortar, lime slurry, paint and other paste spraying and transportation;
  7. the mining industry: the mine containing solid particles of groundwater and slurry water to the ground;
  8. the chemical industry: all kinds of suspensions, grease, all kinds of colloidal pulp, all kinds of adhesives;
  9. the printing industry: high viscosity ink, wallpaper PVC polymer plastic paste and a variety of concentrations of pulp, short fiber pulp delivery;
  10. industrial boilers: power plants, coal slurry transport.

Natural rubber elasticity, excellent tear resistance, good wear resistance, is the preferred material of the stator. But its oil and solvent resistance is not good, anti-acid and alkali corrosion resistance is low, heat resistance is not high these shortcomings limit the application surface. The use of temperature within 60 ℃. Nitrile rubber resistance to gasoline and fatty hydrocarbon oil is particularly good performance, good heat resistance, wear resistance is better, lower than the natural rubber, acid and alkali performance in general, with the natural rubber with the use of the stator material. Use temperature within 90 ℃. Silicone rubber non-toxic and tasteless, mainly used in food and pharmaceutical industry and other health requirements of the occasion. More expensive. The thermal oxidation and ozone stability is high, the chemical inertia. The use of temperature within 100 ℃. Fluorine rubber acid and alkali, oil resistance is oil-resistant rubber; chemical resistance, ozone resistance, resistance to atmospheric aging are excellent. expensive. Mainly used in high corrosion occasions. The solvent rubber does not swell or slightly swell in an organic solvent. To transport organic solvent development.

G series single screw pump is a new type of internal rotary pump. With high efficiency, self-absorption ability, the wide range of applications, etc., for a variety of difficult to transport the media can be used to transport the pump. Therefore, single screw pump in foreign countries is called universal pump. The pump can deliver neutral or corrosive liquids, clean or grinding liquids, liquids containing gas or bubbles that produce bubbles, high viscosity or low viscosity liquids, including liquids containing fibrous and solid materials.

Working Principle and Characteristics of G - type Stainless Steel Single Screw Pump

The working principle of a single screw pump is a single-wire spiral rotor in the double-stranded stator hole around the stator axis for the planetary rotation, the rotor - stator pairs formed between the closed cavity on a continuous, uniform, the volume of the same The medium is conveyed from the suction end to the press-out end. Due to this ingenious working principle, the single screw pump has a general performance of the pump. Its most notable features:

  1. can transport high viscosity media. Depending on the size of the pump, the maximum viscosity of the medium is 37,000 centipoise - 200,000 centipoise.
  2. can be transported with solid particles, grinding particles and fiber medium. Its content can be as high as 40% of the medium, when the medium contained in the powder is fine powder particles, up to 70%, according to the size of the pump to allow the media contained in the solid particle size of up to 2 mm - 40 Mm.
  3. the output of the liquid continuous uniform, stable pressure, agitation is small, the sensitivity of the liquid will not change the composition.
  4. between the flow and speed for a simple proportional relationship. Can be adjusted by adjusting the speed of flow control, coupled with the variable speed motor, can become a variable pump.
  5. the pressure can be automatically adjusted with the output pipe resistance. Between 0-36 (kg / cm) pressure, the user can easily adjust to the required pressure. This is both energy saving, but also to avoid the pressure is too high or too low and affect the process.
  6. simple structure, less wear, easy maintenance.

Compared with other types of pumps:

  • Compared with the centrifugal pump, single screw pump does not need to install the valve, and the flow is stable linear flow.
  • Compared with the piston pump, single screw pump has a better self-absorption capacity, suction up to 8.5 meters high water column.
  • Compared with the diaphragm pump, single screw pump can transport a variety of mixed impurities, containing gas and solid particles or fiber medium, but also transport a variety of corrosive substances.
  • Compared with the gear pump, single screw pump can transport high viscosity material.
  • Unlike plunger pumps, diaphragm pumps and gear pumps, single screw pumps can be used for filling and metering.

G stainless steel single screw pump range of application

G series single screw pump according to the material can be divided into the following three types:

  1. ordinary pump:Main application: oil and water separation device ideal transport pump, sewage treatment device delivery pump; spray device delivery pump; incinerator pump; sewage, fecal transport; lubricating oil, fuel oil, vegetable oil transport; deposited paste and solid particles The transmission of viscous inks, clay, clay paste and pulp; and the transportation of concrete, explosives, coal-water slurry, and so on. In this paper, Kaolin and fiber liquid and other special materials of the pump.
  2. food pump: (using stainless steel and non-toxic rubber material) The main scope of application: wine, undiluted beer buds, hops, milk powder, wheat milk cream, starch, tomato sauce, soy sauce, fermentation broth, mash, honey, chocolate mix, milk, cream, cheese and pulp Transportation, can also be used in the pharmaceutical industry and toothpaste industry and so on.
  3. chemical pump: (using corrosion-resistant stainless steel and corrosion-resistant rubber material) The main scope of application: corrosive oil, chemical media, pigments, thick paint, cosmetics, ointment
