During the operation of the rotor shaft of the gas generator set, there is the problem of journal wear. The dimension of the journal is 129 mm, the wear condition is egg shape, and the wear depth is 0.5 mm. Why do gas generators have journal wear? What are the results?
During the operation of gas generator rotor shaft, because the bearing reaches the service life, the new bearing is not replaced in real time or the bearing is burnt and damaged due to the unexpected. In the absence of bearing support environment, the shaft and the frame bearing seat through-hole conflict appears wear signs.
The normal running clearance between the through hole and the journal in this part is 0.5mm, and there is no relative action. Due to the destruction of the bearing, the journal and the through hole cause the support to wear, the roundness of the journal appearance and the overall strength cause damage, which increases the destructive clearance. During the long-time operation of the building, it is easy for dirt or granular debris to enter the bearing raceway through its gap, which will affect the operation accuracy of the bearing or shorten the service life of the bearing, and will cause hidden dangers to the safe operation of the building.
In view of the recent situation of the journal wear of the gas generator, how should we repair it?
In addition to a few ancient repair technologies such as replacement of new parts, repair welding, brush plating, laser cladding and so on, with the development of science and technology, there is now Solay carbon nano polymer material repair technology, which is similar to a cold welding technology. In the process of online repair, there will be no high temperature, and it is spared the influence of thermal stress of repair welding technology. At the same time, there is no severe limit on the unilateral wear of the shaft, and The whole repair process was also compared with the simple one, and the repair obeyed the high one.
