Prospeed AJ型螺旋CT滑环系统的电刷采用的是碳刷,碳刷与金属滑环长期摩擦会形成碳粉尘附着在碳刷rrrrrrrrn上,碳粉积累到一定程度就会引起扫描中断、丢失图像和机器掉电等机器故障。另外,碳刷与金属滑环长期摩擦还会在rrrrrrrrn碳刷的摩擦面形成氧化膜,会增加接触电阻,影响导电性,信号传输不稳定,也会引发上述故障。所以,定期做好滑环系rrrrrrrrn统的维护工作,对机器的正常运转,保持较高的开机率是十分重要的。
Prospeed AJ spiral CT slip ring system brush is used in carbon brushes, carbon brushes and long-term friction metal slip ring will form carbon dust attached to the carbon brushes r r r r r r r r On n, the accumulation of toner to a certain extent will cause scan interruption, loss of images and machine power failure and other machine problems. In addition, long-term friction between the carbon brush and the metal slip ring also forms an oxide film on the friction surface of the carbon brush, which increases the contact resistance and affects the electrical conductivity. The signal Transmission is unstable, will also lead to the above failure. Therefore, it is very important that the slip ring system is regularly maintained for the normal operation of the machine to maintain a high turn-on rate.
