During the operation of the rotor shaft of the gas generator set, there will be journal wear. The standard size of journal is 129mm, the wearing state is elliptical, and the wearing depth is 0.5mm. Why do gas generators have neck wear problems? What are the consequences?

　　瓦斯發電機組轉子軸在運行過程中，由于軸承已達到使用壽命或燒結事故損壞，未及時更換軸承。在沒有軸承支撐的情況下，當軸和框架的殼體通過孔時，就會發生摩擦和磨損。

　　During the operation of the rotor shaft of the gas generator set, the bearing was not replaced in time because the bearing had reached the service life or was damaged due to sintering accident. In the case of no bearing support, friction and wear will occur when the shaft and frame shell pass through the hole.

　　孔與軸頸間隙約0.5mm，無相對運動。由于軸承損壞，軸頸與軸頸之間的支撐磨損，破壞了軸頸的表面圓度和整體強度，使間隙更具破壞性。在設備的長時間運行的過程,它是容易的污垢或顆粒雜物進入軸承滾道通過這個缺口,這將影響軸承的旋轉精度或縮短軸承的使用壽命,因此創建安全隱患和連續運行的設備。

　　The clearance between the hole and the journal is about 0.5mm without relative movement. Due to the bearing damage, the support between the journal and the journal is worn, which destroys the surface roundness and overall strength of the journal and makes the clearance more destructive. In the process of long-term operation of the equipment, it is easy for dirt or particles to enter the bearing raceway and pass through the gap, which will affect the rotation accuracy of the bearing or shorten the service life of the bearing, so create a potential safety hazard and continuous operation of the equipment.

　　針對瓦斯發電機組軸頸磨損的現狀，應如何進行維修?

　　In view of the present situation of the journal wear of gas generator set, how to maintain it?

　　除了一些傳統修復技術,如更換新零件,修理焊接、刷鍍、激光熔覆等,隨著科學技術的發展已經索雷聚合物材料的碳修復技術,這項技術是類似于冷焊接技術,在線修復過程不產生熱量,避免修復焊接工藝的熱應力的影響,同時對軸向不均勻磨損量也沒有嚴格的限制，且整個修復過程簡單，修復效率高。

　　In addition to some traditional repair technologies, such as replacement of new parts, repair of welding, brush plating, laser cladding, etc., with the development of science and technology, the carbon repair technology of Solay polymer materials has been developed. This technology is similar to the cold welding technology, which does not generate heat in the online repair process and avoids the influence of thermal stress in the repair welding process, At the same time, there is no strict limit on the amount of axial uneven wear, and the whole repair process is simple and the repair efficiency is high.
