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(fā)電機組轉(zhuǎn)子軸在運行過程中，由于軸承已達(dá)到使用壽命或燒結(jié)事故損壞，未及時更換軸承。在沒有軸承支撐的情況下，當(dāng)軸和框架的殼體通過孔時，就會發(fā)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(shè)備的長時間運行的過程,它是容易的污垢或顆粒雜物進(jìn)入軸承滾道通過這個缺口,這將影響軸承的旋轉(zhuǎn)精度或縮短軸承的使用壽命,因此創(chuàng)建安全隱患和連續(xù)運行的設(shè)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(fā)電機組軸頸磨損的現(xiàn)狀，應(yīng)如何進(jìn)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(tǒng)修復(fù)技術(shù),如更換新零件,修理焊接、刷鍍、激光熔覆等,隨著科學(xué)技術(shù)的發(fā)展已經(jīng)索雷聚合物材料的碳修復(fù)技術(shù),這項技術(shù)是類似于冷焊接技術(shù),在線修復(fù)過程不產(chǎn)生熱量,避免修復(fù)焊接工藝的熱應(yīng)力的影響,同時對軸向不均勻磨損量也沒有嚴(yán)格的限制，且整個修復(fù)過程簡單，修復(fù)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.
