The working principle of pipelines mainly includes the basic principles of fluid mechanics and the working mechanism under specific application scenarios.
Principles of fluid mechanics
The working principle of pipelines is mainly based on the basic theory of fluid mechanics. By scientifically and rationally designing the internal shape of the pipeline, such as using elbows with specific curvatures to reduce turbulence, the energy loss of liquid or gas during transmission can be significantly reduced. When gas or liquid flows in the pipeline, due to the action of the continuity equation, the speed at the narrowest part of the pipeline will reach the maximum, and the static pressure will reach the minimum. As the cross-sectional area of the flow changes, the speed of the gas (or liquid) will increase accordingly, resulting in a pressure difference. This pressure difference can be used to measure the fluid or provide external suction for the fluid.
Working mechanism under specific application scenarios
PPR pipelines: The working principle of PPR pipelines is a random copolymer polypropylene material synthesized by a special process, which has good thermal stability, chemical stability and physical and mechanical properties. It is suitable for cold water systems, hot water supply systems and heating systems under certain conditions. The manufacturing process of PPR pipes includes steps such as raw material preparation, extrusion molding, cooling and shaping. The installation is simple and fast, and can be carried out by hot-melt connection or electric fusion connection.
Data pipeline: The data pipeline adopts a streaming processing method, and the data is transmitted in the pipeline in the form of a stream. After the data enters the pipeline from the source, it will be converted and processed by each data processor in turn, and finally reach the target location for storage or further analysis. During the data processing process, the data pipeline will clean, convert and integrate the data according to predetermined rules and logic to ensure the accuracy and consistency of the data.
Venturi tube: The Venturi effect (also known as the Venturi effect) describes that around a high-speed flowing gas, the pressure will decrease, resulting in an adsorption effect. The working principle of the Venturi tube is based on this phenomenon, and the fluid is measured or external suction is provided by the change in velocity and pressure of the fluid in the pipeline. When the fluid is slower in the wider part of the pipeline and faster in the narrower part, a pressure drop will be generated. This pressure drop can be calculated using the Bernoulli equation to obtain the flow information of the fluid.
