Abstract

The invention discloses a fault diagnosis method. The method includes the steps that acquired air blower operating data are received; whether the air blower operating data meet preset fault diagnosisconditions or not is judged; and if it is judged that the air blower operating data meet the preset fault diagnosis conditions, alarm prompts are sent to a data center. The technical problem that theintelligence degree is low as it is not needed to manually check whether an air blower breaks down or not is solved.

Description

technical field [0001] The present application relates to the field of blowers, in particular, to a fault diagnosis method and device. Background technique [0002] Traditional Roots blowers and multistage centrifuges have the characteristics of simple structure, low speed, loud noise and low price. Faults are easy to repair on site. [0003] The air suspension blower is famous for its high precision, high speed, high efficiency, long life and less maintenance. But such equipment is not always without failure. Its speed is generally greater than 20,000rpm, and once a failure occurs, especially a bearing failure, it is often very serious. Also, it is not easy to repair in the field. Therefore, it is very necessary to establish an effective fault diagnosis system. [0004] Aiming at the problem of low intelligence level caused by the need to manually check whether the blower is out of order in the related art, no effective solution has been proposed yet.
