The application field of peristaltic pump is widely used in the laboratory. It is called laboratory peristaltic pump in the laboratory. It is called industrial peristaltic pump in industrial field, and the pharmaceutical industry will also use peristaltic pump. Although the call method is different, the core technology is the fluid transmission of the peristaltic pump. What are the application characteristics of peristaltic pumps in the pharmaceutical industry? Peristaltic pump has the following characteristics in dosing. The 1. peristaltic pump only contacts the liquid with the pump tube. 2. the transmission pressure of the low pressure peristaltic pump is within 0.2 pa. The 3. peristaltic pump can not transmit the solid liquid mixture. 4. the accuracy of peristaltic pump is higher than that of traditional metering pump. The maintenance of the 5. peristaltic pump is more convenient and less expensive. The maximum flow rate of the 6. peristaltic pump is low. If you want to transfer more flow, it is necessary to choose a larger flow peristaltic pump. For this reason, the peristaltic pump is also called a mini peristaltic pump. The 7. peristaltic pump can transmit a high viscosity liquid. What should we pay attention to when we choose peristaltic pumps? The choice of peristaltic pump should be selected from the following aspects. 1. peristaltic pump: the quality of the peristaltic pump determines the working efficiency, just like the atrium in the blood circulation system. 2. peristaltic pump head: peristaltic pump head has a great impact on the overall operation, especially the high precision liquid transmission. 3. peristaltic pump pipe: the choice of peristaltic pump pipe; the material of the peristaltic pump hose determines the filling accuracy and filling quality. Peristaltic pump body determines the performance, and the pump tube plays a role in performance. And the pump tube is an important point to determine the service life and efficiency of the peristaltic pump. As for the parameters of the pump tube, the difference between the inner diameter and the outer diameter determines the flow rate of the transmission liquid. The greater the difference, the greater the flow of liquid. The material selection of the pump pipe should be based on the industry it is engaged in. If the liquid to be transmitted is corrosive, it is necessary to choose corrosion-resistant pump tubes. If it is a high temperature liquid, it is necessary to choose a high temperature resistant pump tube. If it is a regular liquid, choose an ordinary pump tube. As for the performance of the pump, we must consider the compression resistance, the high temperature resistance, the corrosion resistance, the suitable working temperature and the suitable size. Whether it is an industrial peristaltic pump or a laboratory peristaltic pump, or a peristaltic pump for the transmission of liquid medicine, the efficiency of the peristaltic pump is ultimately determined by the transmission precision of the peristaltic pump, and the precision of the peristaltic pump transmission is determined by the good peristaltic pump body, the peristaltic pump head and the hose.
