NCB Internal Meshing High Viscosity Rotor Pump

NCB rotor pump is a common centrifugal pump widely used in various chemical industries, food processing and other industries. Especially suitable for conveying clean liquids or low viscosity liquids. Its characteristics include simple structure, high efficiency, wide applicability, low noise, and strong reliability.

Product Features

• Structural design: NCB rotary pumps are usually composed of a rotor, stator, and pump casing, with a compact structure and reasonable design, suitable for various industrial environments.

• Applicable liquids: mainly used for conveying clean liquids or low viscosity liquids, such as water, fuel, lubricating oil, etc. For these liquids, NCB rotor pumps can provide stable flow and pressure.

• Stable operation: Simple structural design, smooth operation, low noise and vibration, reducing equipment maintenance and operating costs.

• High efficiency: The precise design of the gap between the rotor and stator enables efficient fluid transportation, which helps to reduce energy consumption and operating costs.

• Stable operation: During operation, NCB rotor pumps usually have lower noise and vibration levels, ensuring stable operation and longer service life.

• Widely applicable fields: NCB rotary pumps are widely used in various industrial fields, such as pharmaceuticals, food processing, papermaking, chemicals, energy, etc., especially in situations where efficient liquid transportation is required.

Environmental protection and hygiene: Due to the transmission of liquid between the sealed rotor and stator, the liquid inside the pump is isolated from the external environment, thereby reducing the risk of pollution and the cost of waste liquid treatment.

Product Structure

The NCB rotor pump mainly consists of the following key components:

• Pump casing: usually made of metal materials, the pump casing contains a rotor and stator inside, providing pipelines and support for liquid flow.

• The rotor and stator are the core components of the NCB rotor pump. The rotor is usually an external rotor, and the stator is an internal rotor, forming a sealed working chamber between them. The design of the rotor and stator is very precise, ensuring a very small gap between them, allowing the pump to efficiently transport liquids.

• Bearings and seals: Used to support and seal the rotor shaft to prevent leakage and reduce friction losses.

• Drive device: usually an electric motor or other power source that transmits power to the rotor through a shaft, driving the operation of the pump.

The working principle of NCB rotor pump is based on centrifugal force and the relative motion between the rotor and stator. When the driving device is started, the rotor rotates inside the pump casing while the stator remains stationary. Due to the very small gap between the rotor and stator, the liquid is sucked in and pushed to the outlet of the pump casing. This design ensures stable flow and pressure output.

Product Application

NCB rotor lobe pump, as an efficient centrifugal pump, has a wide range of applications in multiple industrial and commercial fields, mainly including the following aspects:

1. Chemical industry: used for conveying various chemical solutions, suspensions, high viscosity fluids, etc., such as conveying raw materials, intermediates, or finished products in the production process.

2. Petroleum and natural gas industry: used for the transportation of petroleum products such as crude oil, fuel oil, lubricants, asphalt, and their applications in natural gas processing and transportation.

3. Food and Beverage Industry: Used for conveying food grade fluids such as syrup, honey, chocolate, edible oils, dairy products, etc., as well as applications in brewing and beverage production.

4. Pharmaceutical industry: Used for transporting pharmaceutical raw materials, semi-finished products, finished products, etc., pumps are required to have high hygiene standards and good chemical compatibility.

5. Paper industry: used for conveying pulp, chemical additives, and other high viscosity or particle containing suspensions.

6. Water treatment and wastewater treatment: used for transporting sewage, sludge, chemical agents, etc., especially in situations where high concentration and high viscosity fluid transportation is required.

7. Mining and mineral processing: used for conveying slurry, tailings, suspensions, etc., as well as applications in mineral extraction and processing processes.

8. Agriculture: used for the transportation of pesticides, fertilizer solutions, and applications in irrigation systems.

9. Building materials industry: used for conveying building materials such as cement slurry, gypsum, coatings, etc.

10. Plastic and rubber industry: used for conveying high viscosity fluids such as molten plastics and rubber compounds.

The application scenarios of NCB rotor pumps are very wide, and their selection depends on the characteristics of the fluid, the required flow rate and pressure, and the specific requirements of the operating environment. When selecting a pump, factors such as fluid viscosity, chemical properties, temperature, and the presence of particles or suspended solids need to be considered.

Working Principle

The working principle of NCB rotor pump is based on centrifugal force and the relative motion between the rotor and stator. Its working principle is as follows:

Initial stage: When the motor starts, the drive rotor shaft begins to rotate.

Liquid suction: The rotational motion of the rotor generates a negative pressure effect between the rotor and stator through centrifugal force, thereby attracting liquid from the pump inlet into the pump interior.

Liquid ejection: As the rotor continues to rotate, the position and shape of the stator push the liquid to the outlet of the pump casing. During this process, the sealing gap between the rotor and stator ensures continuous flow of liquid from the inlet to the outlet, while maintaining the efficiency and stability of the pump.

Outlet pressure: When the rotor rotates, the liquid forms a certain pressure inside the pump casing, allowing the liquid to be smoothly discharged to the outlet of the system to complete the process of liquid transportation.
