G Handwheel Stepless Speed Change Single Screw Pump

Overview of G type stainless steel single screw pump
The G single screw pump is made of a variety of elastic materials for the stator, so the pump has the characteristics of the high viscosity to 80% fluid delivery and the transport of hard suspended particles medium or containing fiber medium, which has the ability of the general pump species. Its flow rate is proportional to the speed, it is widely used in food metallurgy, paper making, printing and dyeing, chemical industry, fertilizer, pharmaceutical and other industrial sectors. The transmission can be directly driven by coupling, or by high-speed motor, V-belt, gearbox and other devices.

Characteristics of G type stainless steel single screw pump
The pump has the advantages of less parts, compact structure, small size and simple maintenance. The rotor and stator are the wearing parts of the single screw pump, and the structure is simple and easy to assemble and disassemble. Is a new type of pump to mesh volume by circumventing the work principle. The main working parts are eccentric screw (rotor) and fixed bushing (stator). Using non-toxic and tasteless edible rubber, the working temperature can reach 120 degrees Celsius, if the use of high temperature 120 degrees Celsius - 350 degrees Celsius, can contact with the unit. Because of the special geometric beginning of the two components, a separate sealed volume cavity is formed. The medium is carried out evenly by axial flow. The internal flow velocity is low and the volume remains constant. The pressure is stable, so the vortex and agitation are not produced. The output pressure of each pump is 0.6MPa - 1.2MPa, the head is 60m - 120m (clean water), and the self suction height is generally over 3m.

Application range of G stainless steel single screw pump
Screw pump as a general pump, the flow can be adjusted according to the requirements, by changing the speed, the speed can be Gao Ke low, the outlet pressure can increase with the pump series, each increase level, the pressure increased by 0.6MPA, in the following areas and widely used in industry;
1, environmental protection: transfer of filthy mire containing solid particles and short fiber, industrial wastewater and domestic wastewater, especially suitable for oil-water separator, filter press equipment etc.;
2, shipping industry: wheel cleaning, water, oil, low oil sewage sewage medium;
3. Petroleum industry: transporting crude oil, mixture of crude oil and water, mixture of coal gas and water, pouring polymer into the stratum, etc., thus reducing the cost of mechanical oil production and gas recovery, and increasing oil recovery;
4, medicine, daily chemicals: sticky pulp, emulsion, a variety of ointment cosmetics transportation;
5, canned food industry: all kinds of fermented starch, edible oil, sticky honey, syrup, juice, butter, fish and meat and its leftover delivery
6, brewing industry: a variety of fermentation viscous liquid, concentrated distiller's grains, grain products slag, a variety of sauce, pulp and contain fast solid mucus;
7, construction industry: spray and transfer of cement mortar, lime mortar, paint and other paste materials;
8, the mining industry: mine containing solid grains in ground water and sewage water up to the ground;
9, chemical industry: a variety of suspensions, grease, a variety of colloidal slurry, a variety of adhesives;
10, printing industry: high viscosity ink, wallpaper of PVC polymer paste and various concentrations of pulp, short fiber slurry delivery;
11, industrial boiler: power plant, coal water slurry transportation.
Natural rubber has the advantages of large elasticity, good tear resistance and good wear resistance. It is the preferred material for the stator. But its oil resistance and solvent resistance is not good, acid and alkali resistance is low, heat resistance is not high, these shortcomings limit the application surface. The service temperature is 60 degrees centigrade. Nitrile butadiene rubber has excellent performance of gasoline and aliphatic hydrocarbon oil, good heat resistance, good wear resistance, low elasticity, low acid and alkali resistance, and the same material as natural rubber. The service temperature is 90 degrees centigrade. Silicone rubber is non-toxic and tasteless, mainly used in food and pharmaceutical industry and other sanitary occasions. The price is more expensive. The stability of thermal oxidation and ozone is very high, and the chemical inertness is great. The service temperature is 100 degrees centigrade. Fluorine rubber is resistant to acid and alkali, oil resistance is resistant to oil rubber; resistance to chemical corrosion, ozone resistance, atmospheric aging resistance are excellent. Expensive. It is mainly used in high corrosion occasions. Solvent rubber does not swell or slightly swell in organic solvents. Transfer to organic solvent development.
G series single screw pump is a new type of internal meshing rotary displacement pump. It has many advantages, such as high efficiency, strong self suction ability, wide application range, and so on. Therefore, single screw pump abroad is called universal pump. The pump can transport neutral or corrosive liquid, clean or grinding liquid, liquid containing gas or easy to produce bubbles, high viscosity or low viscosity liquid, including liquid containing fiber and solid material.
