The pump head is the core component of the peristaltic pump and an important part of determining the performance of the peristaltic pump. In industrial production, the selection and use of peristaltic pump heads play a key role in improving the accuracy, reliability and efficiency of fluid transport. This article will introduce the working principle, classification and selection of peristaltic pump head in detail from many aspects, to help readers fully understand the peristaltic pump head and correctly choose the products suitable for their needs.

First of all, let's understand the working principle of the peristaltic pump pump head. The peristaltic pump head uses the peristaltic movement of one or more peristaltic pump rubber tubes to push fluid out. When the driving wheel of the pump head rotates, the compression wheel presses on the rubber tube of the pump head, which divides the pump head into the feed chamber and the discharge chamber. The rotation of the driving wheel makes the rubber tube creep continuously under the action of the compression wheel, forming a wriggling movement, so that the fluid is pushed out. This working principle has obvious advantages, such as no pulsation, good reversibility, strong self-priming performance, etc.

According to the material, structure and working mode of the peristaltic pump head, it can be divided into several categories. The common peristaltic pump head classification is geometric pump head, wave pump head, diaphragm pump and so on. Among them, the geometric pump head is suitable for occasions with large flow requirements, and can stably transport various media; The wave pump head has good self-priming performance and corrosion resistance, which is suitable for the transportation of some special media; Diaphragm pump head has good sealing performance and self-priming ability, and has been widely used in chemical, food, medicine and other fields.

When choosing a peristaltic pump head, several factors need to be considered. The first is the flow and pressure requirements, according to the needs to determine the appropriate pump head model and specifications. Secondly, the properties of the medium, such as the viscosity of the fluid, temperature, PH value, etc., choose the pump head material that can adapt to the characteristics of the medium. In addition, it is also necessary to consider the corrosion resistance, wear resistance, service life and other factors of the pump head to ensure that the pump head can run stably for a long time.

At the same time, the installation and maintenance of the peristaltic pump head is also very important. During installation, it is necessary to ensure that the connection between the pump head and the drive device is firm and reliable, and the pipeline is properly installed. During use, the pump head should be checked and maintained regularly to keep it in good working condition. For the maintenance of the peristaltic pump head, the corresponding maintenance plan can be formulated according to the actual situation, the timely replacement of worn rubber tubes and other wearing parts, and regular cleaning and lubrication work.

As the core component of peristaltic pump, the choice and use of peristaltic pump head is very important. Correct selection and good maintenance can give full play to the performance advantages of peristaltic pumps, improve production efficiency, reduce operating costs, and ensure the stability of the production process. Therefore, when choosing the peristaltic pump pump head, it is necessary to comprehensively consider a number of factors to ensure that the appropriate product is selected.

In summary, the peristaltic pump pump head is one of the keys to determine the performance of peristaltic pump. This paper introduces the peristaltic pump head in detail from the aspects of working principle, classification and selection, installation and maintenance. I hope this article can provide readers with valuable information to help them better understand and use the peristaltic pump pump head, so as to improve production efficiency and achieve better economic benefits.
