Peristaltic pump is a kind of equipment that can efficiently and reliably transport fluids, which is widely used in chemical, pharmaceutical, food, water treatment and other industries. As a special type of pump, peristaltic pump has unique working principle and structural characteristics, and is an important equipment in the industrial field. This article will introduce the relevant knowledge of peristaltic pump in detail, to provide a full range of technical support for practitioners in the industrial field, to help you better use peristaltic pump, improve work efficiency and economic benefits.

First, the basic principle of peristaltic pump

Peristaltic pump is a kind of pump that relies on elastic extrusion of liquid, with valveless, no seal, low shear force and so on. The peristaltic pump uses rubber sleeve or pipeline as the transport medium, and the sleeve is driven by oscillator and gear in the pump body, and the liquid is sent into the pipeline according to a certain flow rate by extrusion, so as to complete the pressure transport accurately and stably.

Second, the advantages of peristaltic pump

Compared with traditional pumps, peristaltic pumps have the following advantages in applications:

1, no leakage: peristaltic pump using rubber sleeve as the transport medium, do not need seals, so there is no possibility of leakage, to avoid environmental pollution, cost waste and other problems.

2, low shear force: when the peristaltic pump is transporting liquid, due to the extrusion of the elastic casing, the shear force of the liquid in the tube is very small, which can ensure the quality of the liquid and does not damage or destroy the composition and form of the liquid.

3, reliable operation: peristaltic pump in operation, due to the simple system, fewer parts, easy maintenance and other characteristics, to ensure stable and reliable working state, greatly reducing maintenance costs and failure rate.

4, accurate quantitative: peristaltic pump can accurately adjust the flow according to actual needs, control the speed and efficiency of transportation, improve production quality and economic benefits.

Three, the classification of peristaltic pump

According to different working principles and structural forms, peristaltic pumps can be divided into the following types:

1, rubber casing peristaltic pump: because of its simple structure and reliable performance, it is the most widely used peristaltic pump category in the industrial field. Rubber sleeve peristaltic pump can adapt to different working environments and conveying media, with high conveying pressure, large flow, environmental protection, corrosion resistance and other advantages.

2, gear pump: gear peristaltic pump adopts the form of gear transmission, can stably transport high pressure, high viscosity, high temperature, high concentration and other liquid media, with high reliability, high precision, easy maintenance and other advantages.

3. Plunger pump: plunger peristaltic pump adopts plunger driven transport mode, suitable for conveying low pressure, high flow, high concentration and other media, with stable transport, adjustable flow, simple operation and so on.

Fourth, the application field of peristaltic pump

As a kind of pump with a wide range of application and special advantages, peristaltic pump has been widely used in the industrial field. Specific application areas include:

1, chemical industry: peristaltic pump is suitable for conveying acid, alkali, salt, solvent and other chemical media, to ensure accurate dosing and measurement, to avoid environmental pollution and production accidents.

2, pharmaceutical industry: peristaltic pump can stably and reliably transport biochemical reagents, high-purity drugs and other media, with high drug accuracy, health and safety characteristics.

3, food industry: peristaltic pump can transport liquid food, food additives and other media, with stable flow, consistent temperature, unchanged nutritional composition and other characteristics.

4, water treatment industry: peristaltic pump can transport sewage, wastewater, treatment liquid and other media, with large flow, high pressure, corrosion resistance and other specific.

Five, the selection of peristaltic pump precautions

When applying peristaltic pumps, the following points need to be noted:

1, choose the appropriate model: the model of the peristaltic pump needs to be selected according to the actual working conditions and needs, to meet the flow, pressure, temperature and other requirements of the conveying medium, to avoid unnecessary losses caused by improper selection.

2, pay attention to the layout of the pipeline: the layout of the pipeline needs to meet the actual process requirements, to avoid the pipe passing long, bending, too narrow and other problems, to prevent liquid blockage and leakage.

3, keep clean and sanitary: in the process of use, it is necessary to keep the peristaltic pump clean and sanitary, avoid foreign substances into the casing, affecting the delivery quality and life.

4, regular maintenance: as a mechanical equipment, peristaltic pump needs regular maintenance and maintenance, check the wear and damage of the parts, to ensure its normal operation and durability.

In conclusion, the wide application and continuous development of peristaltic pumps have brought important contributions to industrial production and human life. As an expert in the field of industry, on the basis of mastering the basic principles, advantages, classification, application fields and selection precautions of peristaltic pump, we can make better use of peristaltic pump equipment to improve work efficiency and economic benefits.
