Anatomy: Causes of dripping liquid from the peristaltic pump

When using a peristaltic pump, when the peristaltic pump stops, it will be found that the liquid in the pipeline will slowly drip down until the liquid in the drooping pipeline drops and then stops flowing. This is used for quantification using a peristaltic pump. Tools are a big problem, so what is the reason for this dripping liquid?
     
This is a normal liquid flow phenomenon, mainly because the liquid is filled in the drooping outlet line when it is working, but when the peristaltic pump stops, the liquid in the line outlet is due to its own gravity and liquid. The ductility will naturally drop down the edge of the exit until the liquid in the drooping pipe is completely dripped.
    
In the actual use of the peristaltic pump, there may be special requirements for the pressure. According to the specific requirements, the pressure becomes larger or smaller or constant. What are the factors that affect the peristaltic pump pressure?
1. The gap between the peristaltic pump and the pump tube of the same wall thickness and material is that the pressure is large, that is, the pressure of the pressure tube is increased, and vice versa.

2. The material of the peristaltic pump hose, when the wall thickness and the pressure tube gap are completely the same, the pump tube pressure with higher hardness will be larger, while the hardness of the pump tube will be smaller. This is mainly reflected in the fact that when the silicone tube and the inlet tube are used, the pressure difference is relatively large.
