Problems solved by technology

Due to different frequency of use and requirements for vacuum degree, the status of vacuum pumps varies greatly, making it difficult to formulate maintenance and replacement plans
At present, passive maintenance is mainly used, that is, replacement and maintenance only after the design life is reached or failure occurs. This maintenance method will affect production efficiency and even cause raw materials to be scrapped.
The more intelligent vacuum pumps are used, the more spare parts need to be purchased, resulting in higher capital occupation rate

Abstract

The invention discloses a predictive maintenance system and method for a vacuum pump and an automatic vacuum pump purchasing system. According to the predictive maintenance system, by collecting real-time operation data of the vacuum pump, a real-time operation state of the vacuum pump is obtained based on the real-time operation data of the vacuum pump; whether real-time operation data of the vacuum pump in a current real-time operation state are abnormal or not is judged based on the real-time operation data and the corresponding real-time operation state of the vacuum pump; based on the real-time operation data of the vacuum pump within the specified time interval, the change rate of vacuum pump operation data is calculated to judge whether the change rate of the vacuum pump operation data is abnormal or not; and based on the real-time operation data and historical operation data of the vacuum pump, predicted operation data of the vacuum pump after the preset time interval are calculated, and the health degree of the vacuum pump is calculated based on the predicted operation data of the vacuum pump. The predictive maintenance system can monitor the state of the vacuum pump in real time; and the abnormality of the vacuum pump is found in advance through state alarming, change rate alarming and health degree prediction, and the raw material loss caused by unplanned shutdown and sudden failure is reduced.

Description

Technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a predictive maintenance system and method of a vacuum pump and an automatic vacuum pump purchase device. Background technique [0002] In the production process of high-end manufacturing industries such as panels and semiconductors, vacuum technology is required in many links. It is often used to support simple remote or serial control and adopt air-cooled single-phase intelligent dry pumps. It has quiet operation, compact structure, and occupancy. Features such as small space, but high cost. Because a large number of them are used in key process links, once a sudden failure occurs, it will seriously affect production quality and efficiency, and even cause high-value raw materials to be scrapped. [0003] Smart vacuum pumps can generally only be repaired by the manufacturer. The visual inspection method is usually used for regular inspections. The main purpose is to ensure that t...
