State monitoring and fault diagnosis system for reciprocating type equipment, and application method for state monitoring and fault diagnosis system

Abstract

The invention provides a state monitoring and fault diagnosis system for reciprocating type equipment, and an application method for the state monitoring and fault diagnosis system. The system comprises a measurement and control subsystem, a pedestal, a drive subsystem, a transmission subsystem, a driven part subsystem, a load excitation subsystem, a fault implementation subsystem and a variable working condition implementation subsystem, wherein the drive subsystem, the transmission subsystem, the driven part subsystem, the load excitation subsystem, the fault implementation subsystem and the variable working condition implementation subsystem are disposed on the pedestal. The drive subsystem, the driven part subsystem and the load excitation subsystem are sequentially connected in a mechanical and coaxial manner through the transmission subsystem. The fault implementation subsystem is mechanically connected with the driven part subsystem. The variable working condition implementation subsystem is mechanically connected with the fault implementation subsystem. The measurement and control subsystem is electrically connected with the drive subsystem, the driven part subsystem, the load excitation subsystem, and the variable working condition implementation subsystem. The system can reproduce the operation state which is very similar to the state of large-middle size reciprocating type equipment. The system can generate a smaller monitoring error and higher diagnosis precision in the process of state monitoring and fault diagnosis.

Description

technical field [0001] The invention relates to a state monitoring and fault diagnosis system of reciprocating equipment and an application method thereof, belonging to the technical field of equipment fault diagnosis. Background technique [0002] The existing medium-sized (driving power between 150-500kW) and large-scale (driving power greater than 500kW) reciprocating equipment is the key power equipment of petrochemical enterprises. —Mandatory accessory parts” form. Compared with miniature reciprocating equipment with driving power less than or equal to 5kW, the cost of large and medium-sized reciprocating equipment, the criticality of the link, the importance of operating health and the cost of failure are all greatly increased, and unplanned shutdown will cause huge economic losses. [0003] Compared with the existing petroleum and petrochemical medium and large rotating equipment, large and medium-sized reciprocating equipment has different characteristics in terms o...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problems of large and medium-sized reciprocating equipment in the state monitoring and fault diagnosis of the existing large and medium-sized reciprocating equipment, the monitoring error is relatively low, the diagnostic accuracy is low, and it cannot be applied to large and medium-sized reciprocating equipment in more complicated working conditions, and further proposes a State monitoring and fault diagnosis system of reciprocating equipment and its application method
