The polytetrafluoroethylene is a sealing material with excellent chemical resistance and heat resistance, has small compression deformation, can exert sealing performance for a long time, and has good sealing guarantee by matching with an O-shaped sealing ring on the polytetrafluoroethylene.
When the end cover ring is connected with the roller end cover through threads, the spring piece of the spring brake sealing ring faces the dynamic sealing part after installation is finished, the sealing working lip of the spring brake sealing ring seals the roller main shaft, and the pressure spring brake sealing ring in the system plays a very excellent sealing effect when the sealing working lip is matched with the roller to work; when the end cover ring is screwed into the roller end cover through threads, the mechanical sealing spring is compressed, the spring deforms to generate thrust, so that the movable ring and the static ring are tightly combined, and the end cover ring and the roller end cover form end face sealing through the fifth sealing ring 54. The method has a plurality of seals, the fifth seal ring 54 is in a relative static state relative to the seal part, the phenomenon of air leakage in operation is avoided, the spray angle of the nozzle accurately covers the inner wall of the roller, the temperature of the roller is uniform, and the ice making effect is better.
Similarly, the end cover of the roller realizes end surface sealing through the fourth sealing ring 53, and air leakage in any operation is avoided.
