What is the difference between pipeline pump and sliding vane pump

Release time:

2024-06

Pipeline pumps and sliding vane pumps are commonly used in the industrial field of pump type, they have a wide range of applications in liquid transport. However, there are some significant differences in their structure, working principle, performance characteristics and so on.

1. pipeline pump

Pipeline pump, also known as linear centrifugal pump, is a kind of fluid machinery suitable for a variety of media transportation. Its main features are compact structure, stable flow and easy installation. The working principle of the pipeline pump is based on centrifugal force. The centrifugal force is generated by the rotating impeller, so that the liquid obtains energy and flows out. Pipeline pumps are suitable for conveying clean or lightly contaminated media and are widely used in petroleum, chemical, pharmaceutical, food and other fields.

2. sliding vane pump

Sliding vane pump is a positive displacement pump, mainly through the rotation of the sliding vane and the stator and other components of the sealing volume change to achieve the delivery of liquid. It is characterized by strong self-priming ability, stable flow pressure, and high viscosity liquid delivery. Sliding vane pump is suitable for conveying media containing particles, impurities or high viscosity, commonly used in oil fields, refineries, chemical plants and other occasions.

3. difference

1. Working principle: Pipeline pumps mainly rely on centrifugal force to transport liquids, while sliding vane pumps transport liquids through volume changes.
2. Structural features: The pipeline pump has a compact structure and is suitable for direct installation of pipelines; the sliding vane pump has a unique sliding vane and stator structure.
3. Performance characteristics: pipeline pump is suitable for clean or lightly polluted media, with stable flow; sliding vane pump is suitable for particles, impurities or high viscosity media, with strong self-priming ability.
4. Application: Pipeline pumps are widely used in petroleum, chemical, pharmaceutical and other fields; sliding vane pumps are more used in oil fields, refineries, chemical plants and other occasions.
5. Maintenance: The pipeline pump is relatively convenient for maintenance due to its simple structure; the sliding vane pump may be more complicated for maintenance due to its complex internal structure.

In summary, there are obvious differences between pipeline pumps and sliding vane pumps in terms of structure, working principle, performance characteristics and application fields. In practical applications, the appropriate pump type should be selected according to the specific liquid properties and transportation requirements.
