The air compressor is omni-directionally tracked, and the operating parameters and vibration trend diagrams of the unit are recorded in detail, providing a feasible analysis report for the next overhaul of the aircraft to guide the maintenance or abnormality during the normal operation of the unit. The situation is theoretically analyzed and diagnosed to take practical and feasible retrofit measures.
It is found from the recorded operating parameters table and the vibration trend graph that the amplitude of the point vibration is increasing and the amplitude of the vibration is raised to the left and right. In addition, the various process parameters of the air compressor fluctuated little, and all the parameters were within the control index. The sound and vibration of the unit did not change abnormally, but the four-stage vibration increased slightly. From the perspective of the vibration measurement system, there is no sign that the air compressor is deteriorating, and it is impossible to judge whether the real cause of the increase in the four-stage vibration is the bearing pad or the rotor imbalance. During the period after the increase of the four-stage vibration, through the collection of the operational data, it is found that the amplitude trend of each vibration measurement point is relatively stable during this period.
The reason for the increase in the doubling frequency is mainly due to the excessive wear of the bearing bush, mainly due to the destruction of the rotor dynamic balance. The impeller is heavily fouled by fouling. The impeller has cracks. The impeller is subject to erosion and wear to cause dynamic balance damage.
The reason for the true vibration failure of the unit is the destruction of the rotor dynamic balance. The damage of the high-speed shaft dynamic balance is caused by the erosion of the scouring; the secondary vibration is caused by the imbalance caused by the excessive ash accumulation of the secondary impeller and the imbalance caused by the scouring wear; and the wear of the third-stage bearing is due to the third-order The vibration is gradually increased after the increase.
