目前大多数企业的许多设备还是采用计划检修,而在石油炼制、化工等多个领域中,离心泵这一动力机械占有很大一部分,虽然他它不会象关键大机组那样一旦出现故障会造成巨大的经济损失,但是在现在高速发展及竞争激烈的社会形式上看,总的年总维修费用巨大也是每个企业不得不考虑的问题。本文旨在探讨离心泵故障信号的分析及处理。 Most of the equipment in most enterprises still adopts planned maintenance. In many fields, such as petroleum refining and chemical industry, the centrifugal pump occupies a large part of the power machinery although it does not appear as if a failure occurs in the case of a key large unit Resulting in huge economic losses. However, in the rapidly developing and highly competitive social forms nowadays, the total annual maintenance cost is also a problem that every enterprise has to consider. This paper aims to investigate the centrifugal pump fault signal analysis and processing.
