How to select and use the carbon graphite for machinery? What items should we pay attention to?
For the carbon graphite rings or bearings fitted with metal parts, the difference of thermal expansion coefficients should be noted. When assembling, the interference amount should be chosen reasonably and not too large
In the case of high or high pressure, heat of friction must be derived by an effective method and should be washed when used in a crystalline medium.
Before installation, the two working surfaces of the friction pairs must be ground and the parts must be cleaned. After installation, the friction pairs should be running and running. They should be operated at low or low speed or start in a short time, so that they can be put into normal operation after running in.
Carbon - graphite is a brittle material whose mechanical strength is generally lower than that of metals. Therefore, in the design of the structure should pay full attention to this feature, in the processing and assembly process should be carefully operated, is strictly prohibited to strike with hard objects, to avoid rupture.
Selection must be based on the working conditions of the equipment, taking into account the pressure, wire speed, medium, and grinding materials and other factors, if necessary, after the test selected appropriate.
