Description

technical field [0001] The invention belongs to the technical field of fault diagnosis of low-speed and heavy-duty machinery. Specifically relates to a portable fault diagnosis instrument for low-speed heavy-duty machinery. Background technique [0002] Large-scale low-speed and heavy-duty machinery is often the key equipment of enterprises. Once a sudden failure occurs, not only will the maintenance period be long and the danger will be high, but it will also disrupt the normal production order and cause huge economic losses to the enterprise. Monitoring the working status of large-scale low-speed and heavy-duty machinery, so obtaining early failure information, determining the failure point, and predicting the safe working time of the equipment is an urgent problem for enterprises to solve. Monitoring and diagnosing the early faults of large low-speed and heavy-duty machinery, improving the safe and reliable operation of large-scale low-speed and heavy-duty machinery, pre...

Problems solved by technology

[0004] However, the on-site rapid spectrum analysis of 400 lines of the above-mentioned portable fault diagnosis instrument is weak in analysis ability, and it mainly relies on computers to process data, and it cannot realize networking to monitor large-scale rotating equipment in real time. The extraction of small signals mainly relies on software analysis, which is not conducive to Fault Diagnosis of Large Low-speed Heavy-duty Machinery
