Single Progressive Cavity Pump

G型单螺杆泵(G type single Progressive Cavity Pump)

G TYPE Single Progressive Cavity Pump, commonly known as the G-Type pump, is a specialized type of positive displacement pump that is commonly used in various industrial applications. It consists of two major parts, the rotor and the stator, which work together to create a pumping action.

The G-Type pump is known for its ability to handle a wide range of fluids, including high-viscosity liquids, abrasive materials, and even solids with minimal damage to the product. This makes it an ideal choice for applications in the oil and gas industry, chemical processing, wastewater treatment, and food processing.

One of the key advantages of the G-Type pump is its efficient pumping action. The unique design of the rotor and stator creates a continuous flow of fluid, which results in a steady and consistent flow rate. This makes it an ideal choice for applications that require accurate and precise control of flow rates and pressures.

Another advantage of the G-Type pump is its versatility. It is available in various sizes and configurations, which makes it suitable for a wide range of applications. It can also be customized to meet specific requirements, including suction and discharge sizes, motor power, and material construction.

The G-Type pump is also easy to maintain, which is an important consideration for industrial applications. It does not require frequent repairs or maintenance, and its simple design means that it can be easily disassembled and reassembled for cleaning or repairs.

In summary, the G-Type pump offers a range of advantages for industrial applications. Its efficient pumping action, versatility, and ease of maintenance make it an ideal choice for a wide range of industries, from oil and gas to food processing. With its proven track record of reliability and performance, it is a dependable choice for industrial pumping needs.

• Petroleum industry: thick oil transportation, oil and gas transmission, oil and water separation, and waste oil recovery system.
• Chemical and pharmaceuticals: all kinds of paste, emulsion, suspension, etc.
• Environmental engineering: various sewage transportation, dehydration sludge transportation, flocculant and the measurement and investment of their chemical preparations.
• Mineral engineering: titanium pink, kaolin, calcium carbonate, etc. production equipment, etc.
• Food industry: dairy products, fruit juice, fruit puree, vegetable sauce, beer, etc.
• The papermaking industry: raw materials equipment, pulp and wastewater treatment.

Compared with the advantages of other pumps

• Compared with the centrifugal pump, the single Progressive Cavity Pump does not require a valve, and the flow is stable linear flow.
• Compared with pneumatic diaphragm pumps, single Progressive Cavity Pumps can transport various hybrid impurities to the medium that contains gas and solid particles or fibers, and can also transport various corrosive substances.

Compared with the gear pump, the single Progressive Cavity Pump can transport high -viscosity substances.

• Different from the plunger pump, diaphragm pump and gear pump, the Progressive Cavity Pump can be used for pharmaceutical filling and measurement.

Strong of the Progressive Cavity Pump

The stator is mainly made of rubber. Because it needs to form a closed meshing cavity with the rotor, it is a convergence of the rotor. When the rotor (spindle) rotates and causes continuous friction, it will naturally wear.

Rotary of the Progressive Cavity Pump

The Progressive Cavity Pump rotor (also known as the main axis) is mostly stainless steel, and chrome -plated treatment can be selected;

Because of the meshing relationship with the geometric characteristics of the stator, in addition to natural wear, it is also related to whether the conveying medium contains solid particles and corrosiveness.

The connecting pole of the Progressive Cavity Pump

Connected rod connection rotor and drive shaft. When the motor is running, the transmission shaft drives the connecting rod, and the connecting rod is driven again to play a transmission role. Except for the drive shaft, these mechanical parts are located in the inhalation cavity of the pump.

Drive shaft of Progressive Cavity Pump

The transmission shaft is generally connected to the driver's end (reducer or various driving motors), and its wear is mostly caused by natural wear or changes in the medium working conditions.

Universal

Wanxiang section components are at both ends of the connecting rod. Successfully connect the rotor and the transmission shaft to the connecting rod; because the universal joint assembly consists of various small parts, we need to check the seal and lubrication regularly.

1. The pressure of the single Progressive Cavity Pump is determined:

The maximum output pressure of the single Progressive Cavity Pump is determined based on the number of guides of the jersey level, that is, the number of bands:

• Level 1 Progressive Cavity Pump: high work pressure is 0.6 mPa;
• Level 2 Progressive Cavity Pump: High work pressure is 1.2 MPA;
• Level 4 single Progressive Cavity Pump: high work pressure is 2.4 mPa;

Due to the different situations of the Progressive Cavity Pump conveying medium, for the medium that contains severe wear, please refer to the number of band -grade levels.

Table 1: Choose the jujiao level according to the wear of the medium

2. Single Progressive Cavity Pump speed selection:

Due to its structural characteristics, the single Progressive Cavity Pump is mostly used in the liquid that transports higher viscosity and liquid containing particles. Therefore, the choice of the transfer is very critical. According to experience, list Table 2 and Table 3. You can comprehensively comprehensively according to the specific situation. consider.

Table 2: Choose the Progressive Cavity Pump speed according to the abrasion of the medium

＊ When the specifications of the pump are large, the speed should be lower. ＊ The special cases that are delivered and their wear characteristics are given in the table. Please note that the characteristics of the medium change with the change of the concentration and temperature.

Table 3: Select the pump speed according to the medium viscosity

＊ You must also be based on experience when choosing a speed, because some other factors also affect the choice of speed. At the end, it is best to negotiate with the manufacturer while determining the above values.

3. Single Progressive Cavity Pump lining rubber material selection:

The single Progressive Cavity Pump lining is a rubber product, and it is also a destructive part of the single Progressive Cavity Pump. Its choices are good or bad, which directly affects the life of the band. Generally, the life of the band is 3-6 months. , Band may fall off from the steel pipe or drop the block. Therefore, we are required to understand the basic characteristics of rubber and the adaptability of a variety of different medias, and list Table 4 and Table 5 according to our experience.

4. Material combination selection:

Different material combinations are required to transport different properties.

5.Performance table: generallyThe performance table or characteristic curve of the single Progressive Cavity Pump is data when the medium (viscosity is 1CST) with 20C water. The flow and the axis power under different viscosity are different.

6. Axis:

According to the needs and conveying medium, two types of mechanical sealing and filling can be used, and these two structures can be interchangeable.

7. Driver method of pump:

Because the single Progressive Cavity Pump is a low -speed pump, there are many drivers for pumps. Generally has a low -speed motor direct connection (level 4, level 6), gear deceleration motor drive, stepless transmission driver and other methods.
