I. Overview of G Type Single Screw Pump

结构紧凑,体积小,对介质的适应性强,流量平稳,压力脉动小。 Kaiyang G series single screw pump has compact structure, small volume, strong adaptability to medium, stable flow and small pressure pulsation. The maximum working pressure can reach 2.4MPa; the maximum diameter of the media particles can reach 20mm; the working temperature can reach 120 ° C. If other working conditions are required, Shanghai Kaiyang can customize it. Because of its superior performance, it is widely used in food, metallurgy, papermaking, printing and dyeing, chemical, fertilizer, pharmaceutical and other industrial sectors. Let's briefly introduce the working principle of the G-series single screw pump:

G type single screw pump is a kind of internal meshing closed displacement pump. Its main working parts are eccentric screw (rotor) and fixed bushing (stator). When the rotor of a single-screw pump is planetary rotated around the stator axis in a double-line spiral stator hole, a separate sealed solution cavity is formed between the rotor and the stator. The operation of the rotor will continuously convey the medium in the sealed cavity from the suction port of the pump body to the extruding end. Due to the fixed geometry of the rotor, the pressure in the pump cavity is very stable, which enables the pump to continuously and uniformly pump liquid.

Shanghai Kaiyang has been pursuing innovation and development in the pump industry. Shanghai Kaiyang is a major R & D project product for the G-type single screw pump. G type single screw pump is generally called "MONOPUMPS" in western countries, translated into Chinese as "Mono pump", and it is also called "eccentric rotor pump" in Germany. After years of research and practice, Shanghai Kaiyang can customize explosion-proof single screw pumps, gear speed single screw pumps, electromagnetic speed single screw pumps, hopper single screw pumps, stepless speed single Progressive cavity pump; pump body material can be customized: cast iron, stainless steel 201, stainless steel 304, stainless steel 316L, etc.

Selection suggestions for G type single screw pump

As the use of screw pumps is relatively wide, it is very important to select screw pumps with different speed adjustment methods and different materials for pumping different viscous and corrosive media. For the convenience of customers, Kaiyang G single screw pump has been developed and produced the following: cast steel single screw pump, stainless steel 201 single screw pump, stainless steel 304 single screw pump, stainless steel 316L single screw pump; rubber sleeve can be divided into ordinary rubber, Low-toxic rubber, non-toxic rubber, EPDM, etc. The speed regulation method can be divided into fixed gear speed, stepless speed regulation, electromagnetic speed regulation, etc., and a hopper can be added at the feeding place according to customer needs. 以下几个要点: According to our factory's past experience and customer feedback, the following points can be noticed when selecting the G type single screw pump :

1.Selection of pump body material and stator and rotor material

1) Ordinary liquid (PH neutral, weak acid and alkali, such as ordinary sludge, ordinary sewage, building materials, etc.): Cast steel pump body + Ding Qing rubber stator + stainless steel 201 rotor can be selected.

2) Food, medical raw materials and other sanitary liquids: stainless steel 304 or 316L pump body + non-toxic rubber stator + stainless steel 304 rotor can be selected.

3) Viscous liquid or liquid that is not easy to flow: choose the material according to the specific liquid properties, more importantly, the import requires a hopper, and the motor needs a gear reduction.

2.Motor selection and deceleration mode selection

1) In the state of liquid flow and no flammable and explosive media, select ordinary three asynchronous motors.

2) The state of flowing water in the liquid process, including flammable and explosive media, select explosion-proof motors.

3) The liquid has a certain viscosity, but it can flow, and a gear reducer is required; if a different flow is required, a stepless speed governor is added.

4) The liquid is viscous and not easy to flow. Gear reduction is required, plus hopper and auger; if different flow is required, stepless speed governor is needed.

5) If different flow is required, based on the frequency conversion control cabinet, you can choose to add a frequency conversion motor to adjust the flow.

Fourth, the use of G-type single screw pump

G型单螺杆泵 的出口压力可以随着级数的增加而增加,每增加一级压力可以增加 0.6MPa,因此楷阳G型系列单螺杆泵受到社会各行业的好评: The outlet pressure of Kaiyang G-type single-screw pump can increase with the increase of the number of stages, and the pressure can increase by 0.6MPa for each additional stage . Therefore, Kaiyang G-type single-screw pumps have been well received by various industries in society:

1. Environmental protection: industrial sewage, domestic sewage, muddy water containing solid particles and short fibers. Especially suitable for oil-water separator, plate and frame filter press and other equipment.

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

3. Petroleum industry: transportation of crude oil. In recent years, it has been particularly successful in pumping a mixture of crude oil and water at a depth of thousands of meters underground, and a mixture of coal field gas and water in a coal field, thereby greatly reducing the cost of mechanical oil production and coal field gas extraction. When the oilfield reaches the later stage, screw pumps are used to inject polymer into the formation to increase oilfield recovery.

4, medicine, daily chemical: all kinds of viscose paste, emulsion, various ointment cosmetics and other transportation.

5. Food canning industry: transportation of various viscous starch, cooking oil, bee dense, sugar sauce, fruit pulp, cream, minced meat and minced meat and their wastes.

6. Brewing industry: various fermentation viscous liquids, thick wine tanks, grain products, various sauces, pulps, and mucus containing solids.

7. Construction industry: spraying and conveying of cement mortar, lime mortar, coatings and pastes.

8. Mining industry: underground and sludge water containing solid particles in the mine are discharged to the ground.

9. Chemical industry: various suspensions, greases, various colloidal pulps, and various adhesives.

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