Peristaltic pump is a very common type of pump. With its unique working mechanism and highly accurate flow regulation, it is widely used in many industries, such as chemical, food processing, medicine and water treatment. However, in the process of using the peristaltic pump, there are often some problems, one of which is the peristaltic pump deviation.

Peristaltic pump deviation refers to the phenomenon of flow error or pump head pressure instability in operation. It can be caused by a variety of factors, including uneven pump tube extrusion, fluid viscosity changes, pump head damage, and pump tube aging. These factors will cause the peristaltic movement of the pump is not stable enough, thus affecting the delivery effect of the fluid.

First of all, the uneven extrusion of the pump tube is one of the common causes of peristaltic pump deviation. The pump tube will inevitably be subjected to external force during operation, and it will be worn or deformed after long-term use. If the extrusion of the pump pipe is not uniform, it will lead to fluctuations in the operation of the pump, which will affect the stability of the flow rate. Therefore, regular inspection and replacement of damaged pump tubes is the key to ensure stable performance of peristaltic pumps.

Secondly, the change of fluid viscosity will also affect the operation of the peristaltic pump. The viscosity of a fluid refers to the size of its internal friction, and different types of fluids have different viscosity characteristics. When the fluid viscosity changes, the peristaltic movement of the pump is subject to certain resistance, which affects the accuracy of the flow rate. Therefore, when choosing a peristaltic pump, it is necessary to select the appropriate pump type and pipeline according to the nature of the specific fluid to ensure the best operating effect.

In addition, the damage of the peristaltic pump head is also one of the reasons for the deviation. The peristaltic pump is usually composed of two parts: the driving unit and the pump head, and the roller and pressure roller in the pump head are the key pumping functions. If these parts are damaged or seriously worn, it will directly affect the stability of the pump and the accuracy of the flow rate. Therefore, regular inspection and replacement of the pump head is one of the important measures to maintain the performance of the peristaltic pump.

Finally, the aging of the peristaltic pump tube will also lead to the deviation of the pump. After a period of use, the pump pipe will be aging due to the friction and pressure of the fluid. After aging, the pump pipe will become more fragile and vulnerable, resulting in unstable peristaltic movement of the pump. In order to avoid this problem, it is very important to replace aging pump pipes regularly.

In short, peristaltic pump deviation is a common problem in the process of use, but we can take some measures to reduce or avoid these deviations. Regular inspection and maintenance of the various components of the peristaltic pump, especially the pump pipe and pump head, is the key to ensure the stable performance of the peristaltic pump. In addition, ensuring that the appropriate pump type and pipeline are selected and adjusted according to the viscosity characteristics of the actual fluid can also effectively reduce the occurrence of peristaltic pump deviation.

The application prospect of peristaltic pump is very wide, and it has an important position in chemical industry, food processing, medicine and water treatment industry. By fully understanding and solving the peristaltic pump deviation problem, we can better use and apply the advantages of peristaltic pump, improve production efficiency and product quality.
