How to synthesize polymer liquid crystals in silicone hoses and make them into silicone hoses

How to solve the liquid dripping from the filling port of the peristaltic pump silicone tube from the peristaltic pump tube Reason analysis:
In this case, the main reason is that the silicone tube of the peristaltic pump has a high viscosity of the pharmaceutical liquid, and the flow rate of the liquid at the filling port is not enough to overcome the adhesive force between the liquid and the needle port, which causes the liquid in the silicone tube of the peristaltic pump to hang on the filling needle. superior.  
Solution:
①During the filling process, the filling needle of the silicone tube of the peristaltic pump should be moved up and down, so that the filling needle can touch the liquid to be filled during the filling process, and then lift the filling needle after filling, which can effectively solve the problem Peristaltic pump silicone tube liquid hanging needle case.
②After the filling is completed, the back-suction function of the driver is used (the Qili distribution type peristaltic pump has this function), so that after the peristaltic pump silicone tube is filled, the viscous stick hanging on the needle can be quickly cut off through the back-suction of the pump head. Liquids can also effectively solve the problem that the peristaltic pump silicone tube liquid hangs on the needle.
