Because the PFA tube extruder is made of metal materials with high hardness, it will suffer from vibration, impact and other interaction forces in the whole process of production operation, which will cause the gap between the parts and cause wear. Traditional repair methods include surfacing, hot spray, brush, etc., but there are some disadvantages: surfacing will cause the surface of parts to achieve high temperature, resulting in deformation or cracking of parts, and then harm the dimensional accuracy and all normal application. In more severe cases, it can also cause bone fractures; Although the brush cross has no thermal hazard, but the thickness of the cross layer can not be too thick, pollution is more serious, and greatly limited the application.
At present, most of the western countries choose the way of polymer composite materials to deal with the problem, the more mature application is the technical system of Zhaohua. Its comprehensive performance and ready-to-process characteristics allow for the requirements and accuracy of repair applications, and also reduce the impact and vibration of the equipment during the whole operation process, and increase the service life. Because the material is variable, when the material is impacted by external force, the material will deform and absorb external force with the expansion and contraction of the bearing or other parts, and always keep close coordination with the bearing. Reduce the likelihood of wear and tear.
In the process of pre-screwing the single screw extruder bolt of PFA tube, the bolt is deformed due to the tensile stress, and its recovery stress makes it closely connected with the connected seal, so that with the passage of time, it is lengthened and local tensile. The extension deformation becomes long-term deformation, the recovery stress decreases, resulting in stress relaxation and torque reduction, so that the bolt loosens, the thread slips and wears, and even the internal thread of the fastener is damaged in serious cases.
