As a common positive displacement pump, progressive cavity pump is widely used in various fields, and its unique working principle and characteristics make it an important part in the field of fluid transfer. Below we will introduce the main types of progressive cavity pumps and their characteristics.
Main types of progressive cavity pumps:
Progressing cavity pumps:A progressing cavity pump is the most basic type of progressive cavity pump, which consists of a screw and a lined housing. The screw rotates in the pump to push the liquid along the spiral groove of the screw to achieve liquid transfer.
Twin Progressive Cavity Pumps:Twin screw pumps have two screws moving inside the pump, which has a higher conveying capacity and a more stable flow rate than a single screw pump. Twin screw pumps are commonly used for the transfer of high-flow, high-viscosity liquids.
Three-screw pump:Compared with the twin screw pump, the three-screw pump has an additional screw, which makes the pump have a higher flow rate and better stability, and is suitable for occasions with high requirements for conveying accuracy.
Multi Progressive Cavity Pumps:Multi-screw pumps typically contain more screws, which makes the pump more effective when conveying high-viscosity, high-temperature liquids. The multi-screw pump is suitable for liquid transfer in some special working conditions.
The main features of the progressive cavity pump:
Positive displacement conveying:The screw pump is a positive displacement pump, which realizes the forward, continuous and stable transportation of fluids through the rotation of the screw, and is suitable for liquids of various viscosities.
Adaptable:Progressive cavity pumps are suitable for all kinds of liquids, including high viscosity, high temperature, and liquids containing solid particles, and have strong adaptability.
Low noise, smooth conveying:The working of the progressive cavity pump is relatively stable, the noise is low, and it is suitable for some occasions with high requirements for environmental noise.
High efficiency and energy saving:The screw pump has high conveying efficiency, which can reduce energy consumption and achieve energy saving and environmental protection.
Easy maintenance:Progressive cavity pumps are relatively simple in structure, relatively easy to maintain, and usually have a long service life.
Overall, progressive cavity pumps play an important role in the field of liquid transfer due to their many types and unique operating principles. By choosing different types of progressive cavity pumps, we can meet the needs of fluid transfer under different working conditions, and provide reliable support for the production of various industries.
