Peristaltic pump is a commonly used fluid conveying device, and its structural design and application have been widely concerned and studied. This paper will introduce the structure composition, working principle and application in different fields of peristaltic pump in detail.
The structure of peristaltic pump mainly includes pump head, peristaltic element and driving device. The pump head is the core part of the whole pump, which realizes the fluid transport through the compression and release of the peristaltic element. The peristaltic element consists of a rubber tube or a metal peristaltic plate, which allows fluid to be inhaled and expelled by flattening and restoring motion. The driving device usually uses an electric motor, which provides power and drives the movement of the peristaltic element.
The working principle of peristaltic pump is very simple, after the fluid is sucked by the pump head, the peristaltic element is flattened to form a closed peristaltic chamber, and then the peristaltic element returns to its original state, pushing the fluid in the peristaltic chamber forward. This form of flattening and restoring movement makes the peristaltic pump have extremely low shear force and pulsation, and is suitable for transporting fluids with high concentration, high viscosity and easy holding.
Peristaltic pumps have a wide range of applications. First of all, in the field of chemical industry, peristaltic pump is often used to transport acid, alkali, salt and other corrosive media, its structure and material selection has great advantages. Secondly, in the food and pharmaceutical industry, peristaltic pumps are suitable for conveying high-viscosity, easily perishable liquids, such as sauces, soy sauce, creams, etc. In addition, in environmental protection projects, peristaltic pumps are widely used in sludge treatment, sewage treatment and other fields, because they have self-priming exhaust function, which can effectively improve treatment efficiency.
The application of peristaltic pump also covers pharmaceutical, electric power, metallurgy, petroleum, paper and other industries. In the pharmaceutical industry, peristaltic pumps are often used to deliver high-value products, such as vaccines, antibiotics, etc. In the power industry, peristaltic pumps are widely used in water supply, lubrication and drainage systems. In the metallurgical and petroleum industries, peristaltic pumps are used to transport corrosive liquids, high temperature media, etc. In the paper industry, peristaltic pumps are used to transport pulp, dyes and so on.
In short, peristaltic pump as a special fluid transport equipment, its structure and working principle determine its wide application in different fields. Through continuous research and improvement, the position of peristaltic pump in related industries will be more important.
