Fault diagnosis device and method for petrochemical rotating unit

Abstract

The invention discloses a petrochemical rotary unit fault diagnosis device, which comprises a unit engine base. The unit engine base is provided with nine parallel T-shaped grooves. Each T-shaped groove is provided with a pad base. The nine pad bases are provided with an alarm, a monitoring device, a collector and a server, a signal processing module, a variable frequency motor controller, a motor, a torque transmission device, a gearbox and an air compressor respectively. The motor and the torque transmission device are connected through an elastic coupling, and the torque transmission deviceand the gearbox are connected through an elastic coupling; the gearbox and the air compressor are connected through an adjustable coupling; the gearbox is provided with a temperature sensor; and thetemperature sensor is connected with the signal processing module. The invention also discloses a petrochemical rotary unit fault diagnosis method. The petrochemical rotary unit fault diagnosis deviceand method can diagnose the fault of petrochemical units intelligently, judge states thereof and carry out accurate processing.

Description

technical field [0001] The invention specifically relates to a fault diagnosis device for a petrochemical rotary unit and a diagnostic method thereof, belonging to the field of fault diagnosis of petrochemical rotary equipment. Background technique [0002] With the widespread use of rotating machinery and equipment in the petrochemical industry, petrochemical units are increasingly tending to be automated, large-scale, and high-speed, and their composition and structure are becoming more and more complex. At present, there are many fault diagnosis techniques for petrochemical units at home and abroad, but due to the special environment in which petrochemical units are located, there are many factors affecting the site, and they have characteristics such as uncertainty, which have a negative impact on the accuracy and timeliness of fault diagnosis. influences. However, if the failure of the unit cannot be found in time, coupled with the long-term operation of the unit, the ...

Problems solved by technology

At present, there are many fault diagnosis techniques for petrochemical units at home and abroad, but due to the special environment in which petrochemical units are located, there are many factors affecting the site, and they have characteristics such as uncertainty, which have a negative impact on the accuracy and timeliness of fault diagnosis. influences

However, if the failure of the unit cannot be found in time, coupled with the long-term operation of the unit, the failure will become more and more serious. low; on the other hand, it may cause the shutdown of the workshop of the enterprise, affect the economic and social benefits of the enterprise, and cause huge losses; the important ones may cause major accidents that endanger human life and safety.
