What are the factors that affect the actual effect of fluorine rubber sealing ring application?

Many mechanical equipment will have the shadow of silicone rubber sealing ring, so do we know what are the factors that endanger the application efficiency of fluorine rubber sealing ring? Let me give you a brief introduction below. The machining accuracy of mechanical equipment is not good: There are many reasons for the poor machining accuracy of mechanical equipment. Some of them are the poor machining accuracy of the fluorine rubber sealing ring itself. These reasons are very easy to attract everyone's attention and are also very easy to find. But sometimes the machining accuracy of other components of the pump is not good. For these reasons, it is not easy to attract everyone's attention. For example: the increase of the precision of the pump shaft, coupling, pump casing, and sealed inner cavity is not good. For this reason, the sealing effect of the fluorine rubber seals sealing ring is very moldy. Excessive vibration: The vibration of the fluorine rubber sealing ring is too large, which will eventually cause the loss of sealing effect. However, the reason for the slightly larger vibration of the fluorine rubber sealing ring is usually not the reason of the fluorine rubber seals sealing ring itself. Other parts of the pump are the root cause of the vibration. Good, the flatness of the coupling is poor, the axial force is large, etc. What are the factors that endanger the application efficiency of the fluorine rubber sealing ring? The radial channeling of the pump shaft of the silicone rubber sealing ring is large: the protruding surface of the fluorine rubber sealing ring must have a certain specific pressure, so that it can have a sealing effect, which stipulates The tension spring of the fluorine rubber sealing ring must be reduced by a certain amount, and a torque is given to the inner hole of the fluorine rubber sealing ring, and when it is rotated, the protruding surface can generate a specific pressure specified by the sealing performance. In order to better ensure this specific pressure, the fluorine rubber sealing ring stipulates that the pump shaft should not have a large amount of channeling. The fluorine rubber sealing ring cannot accept the axial force in the whole process of application. If there is an axial force, The harm to the fluorine rubber sealing ring is not optimistic. Sometimes due to the unscientific overall planning of the axial force balance organization of the pump and the level of manufacturing, equipment, and application, the generated axial force is not balanced. The fluorine rubber sealing ring receives an axial force, and the temperature of the sealing cap during operation will be higher. For polypropylene materials, it can be melted at high temperature, so the sealing effect will be lost quickly after the pump is started, and the pump will not stand still. The leak-tight inner bore exhibits an interrupted leak condition when moved. There is no auxiliary flushing management system or the setting of the auxiliary flushing management system is unscientific: the auxiliary flushing management system of the fluorine rubber sealing ring is very critical. The auxiliary flushing management system of the fluorine rubber sealing ring can reasonably maintain the convex surface, and has the functions of cooling, smoothing, and flushing away dirt. Sometimes the overall planner is not effectively equipped with the auxiliary flushing management system, and the sealing effect cannot be achieved; sometimes although the overall planning staff has planned the auxiliary management system as a whole, due to the residue in the flushing liquid, the total flow of the flushing liquid, the working efficiency, The pressure is not good, the overall planning of the flushing port is not scientific, etc., and the sealing effect is also not achieved.
