通过对罗茨真空泵转子磨碰故障机理进行研究，以及对现场故障模拟分析发现，罗茨真空泵的转子磨碰故障的特征实际上表现在啮合齿轮载荷波动引起的啮合振动及其边领，通过对齿轮啮合频率及其边频．的实时在线监测，可以有效地捕捉到早期故障信息，避免重大恶性事故。本文提出的冲击能量捕捉法对于监测其他转子磨碰故障也有很大的实际意义。
Through the research on the failure mechanism of Rotor vacuum pump rotor abrasion and the field failure simulation analysis, it is found that the rotor abrasion failure characteristic of Roots vacuum pump is actually manifested in the meshing vibration caused by meshing gear load fluctuation and its side collar. Gear meshing frequency and its side frequency. Real-time online monitoring, you can effectively capture the early fault information, to avoid major malignant accidents. The impact energy capture method proposed in this paper is also of great practical significance for monitoring the failure of other rotors.
