peristaltic pump
A peristaltic pump is a positive displacement pump that works by periodically squeezing an elastic hose (also called a pump tube) through a roller or a pressure block, thereby forming negative and positive pressure inside the hose and driving the fluid forward in the pipeline. The characteristic of this pump is that the fluid is completely isolated inside the hose and does not come into direct contact with the pump body, so it is very suitable for conveying fluids that are sensitive to contamination, such as biological samples, chemical reagents, etc.
A peristaltic pump is mainly composed of the following parts:
Driver: Provides power to drive the roller or pressure block to perform periodic motion.
Pump head: The component that mounts the hose and the roller or pressure block is the core part of the peristaltic pump.
Hose: As a medium for fluid delivery, it is periodically squeezed and released by the roller or pressure block.
Control system: Used to control the speed, flow rate and other parameters of the peristaltic pump to achieve precise control.
The advantages of peristaltic pumps include:
No pollution: The fluid is completely isolated from the pump body to avoid cross contamination.
High precision: High-precision flow control can be achieved by precisely controlling the movement of the roller.
Strong self-priming ability: the hose can form negative pressure during the extrusion process, thereby sucking in fluid.
Simple maintenance: the hose is easy to replace, reducing maintenance costs.
Wide range of applications: it can transport fluids of various viscosities, including high viscosity, corrosive, shear-sensitive and volatile fluids.
Peristaltic pumps are widely used in many fields, such as medicine, biology, chemistry, environmental protection, food and other industries. In the pharmaceutical industry, peristaltic pumps are often used for drug delivery, cell culture, vaccine preparation, etc.; in the biological industry, peristaltic pumps are used for microbial fermentation, liquid circulation in bioreactors, etc. In addition, peristaltic pumps are also widely used in sample processing, solution preparation, chemical analysis, etc. in laboratories.
In general, peristaltic pumps play an important role in many fields with their unique working principles and advantages.
