Microperistaltic pump is a kind of pump for conveying small flow liquid, which has the advantages of high flow accuracy, stable pressure, adjustable flow, etc., and is widely used in laboratory, medical, environmental protection and pharmaceutical fields. The principle, characteristics and application of micro-peristaltic pump will be introduced in detail.

The principle of micro-peristaltic pump adopts the principle of peristaltic pump, that is, the peristaltic element in the compression pump head is used to realize the transportation of liquid. In the pump head, the peristaltic element is usually an elastic tube that compresses and releases the wall via an external roller or peristaltic plate to allow the fluid to be transported. This design can not only avoid the contact between the liquid and the pump, avoid cross contamination, but also ensure the accuracy and stability of the flow. Ii. Characteristics

1. High flow accuracy: micro peristaltic pump transmission mechanism is simple, can achieve small flow transmission, the flow accuracy can reach ±1%.

2. Pressure stability: Because of the working principle of peristaltic pump, the pressure fluctuation is small, which can ensure the stability of the conveying liquid.

3. Flow adjustable: the flow of micro-peristaltic pump can be adjusted by adjusting the speed of the pump head or the diameter of the peristaltic element.

4. Strong corrosion resistance: the pump head materials of micro-peristaltic pump are mostly good corrosion resistance materials, which can adapt to the transportation of different liquids.

5. Compact size: micro peristaltic pump compact size, suitable for laboratory and other small occasions.

Iii. Application

1. Medical field: microperistaltic pumps can be used to deliver drugs, such as intravenous injection and heparin pumps.

2. Environmental protection field: micro-peristaltic pump can be used to transport sewage and wastewater treatment, such as dosing, adjust pH value, etc.

3. Laboratory field: Micro-peristaltic pump can be used for liquid transport with small flow in the laboratory, such as cell culture, drug screening, etc.

4. Pharmaceutical field: microperistaltic pump can be used for transportation in pharmaceutical process, such as preparation molding, drug packaging, etc.

To sum up, microperistaltic pumps have the characteristics of high precision, stable pressure, adjustable flow, strong corrosion resistance and so on, which are widely used in medical, environmental protection, laboratory and pharmaceutical fields. With the development of science and technology and the increase of demand, the application prospect of micro-peristaltic pump will be more broad.
