Screw Compressors Online Condition Monitoring And Control System

The modem production requires heavy demand of equipment repairs.The quick and high caliber repair is vitally important to the long cycle and successive motion of the machines.The condition monitering techniction is fundamental to diagnosis of engine trouble. At present,There are three typical types of machine condition monitering.They are offline terminal monitering suetem,online condition monitering but offline fault diagnosising system and automaticly online condition monitering and fault diagnosis system. The automaticly online condition monitering and fault diagnosis system is the most advanced way .By this way ,not only the condition of machine is monitered ang diagnosised automaticly ,but also data processing and analyzing is carried on online automaticly . The intellectual comparison.and judgementof machine is processed by specialistic experrience and correlative rule too.Above all,this paper descripes the demands of system's function . On the basis of these demends,The screw compressor online condition monitering and fault diagnosis hardware system is developed according to open,low-cost,reliable and efficient prinpicle ..the paper also describes in detail how to select sensor type and moniter position according to character of running system and the faults generated. ofen in machine .The vibration sensors and technologic process sessors is of premium properties.The data acquisition system consists of yanhua computers and low-cost, excellent data acquisition cards based on ISA bus. The important parameters acquisition of the machine is realized by .It.The software of the screw compressor online condition monitering and fault diagnosis system is composed of Online Monitoring & Forcasting System,Signal Analysis & Processing System developed in java assembly language.this paper also discussed the structer and function .At last ,the paper describes the production system that provides guarantee for the compressor. This sustem adopted Mitsubishi PLC.The project this paper presented has been putted into production in the October last year .To this day,the system has been run smoothly .the system technology level is...
