Research On The Condition Monitoring System For Reciprocating Compressors

Reciprocating compressors are key equipments in many industries. The results of the faults of the reciprocating compressors will be disastrous. It is necessary for reciprocating compressors to build up a condition monitoring system.A condition monitoring system for reciprocating compressors is introduced in this thesis. The methods and processes to implement the system are suitable for many other applications in reciprocating machine.First of all, after the introduction of the principle of reciprocating compressors, this thesis analyses the methods that represent the condition of reciprocating compressors and introduces the means of monitoring typical faults of reciprocating compressors.Secondly, two different ways, namely, on-line and off-line ways that are adopted to implement the condition monitoring system are compared. According to the practice, the latter is adopted. The condition monitoring system for reciprocating compressors is built up after selecting variables and samples. The technique named equal-space sampling is implemented by software and is used to sampling.Thirdly, the software of the condition monitoring system is completed. The database and modules of the system are designed after the analyses of requirements, business process and data flow. After implementing the database, the software with many approaches of signal processing and beautiful and friendly interface is implemented by programming by combining Visual C++ with MATCOM and using Object-Oriented approaches.Finally, after giving a case, the problems of the system are discussed. This thesis presents the solutions of the problems and proposes the architecture of condition monitoring center for reciprocating compressors.This condition monitoring system for reciprocating compressors is used in practice. People benefit from it.
