Research On Pump Safety Monitoring And Fault Diagnosis

Crude oil gathering and transferring system is one of the key equipment of oiltransfer pump unit. Throughout the enterprise normal operation of productiondepends entirely on the safe operation of the equipment. In modern production, inorder to reflect the well or oil transfer pump group of faults in the pumpedstorage power station, the real-time running state monitoring of pump unit isrequired. By installing security monitoring system, can achieve real-timemonitoring of running status, analysis of equipment failure or potential failure,ensure the equipment normal use and safety.This thesis is based on virtual instrument technology of pump design ofmonitoring and fault diagnosis system. Using mobile data recorder as the dataacquisition module, vibration of oil transfer pump motor pulse signals andtemperature signals for real-time monitoring. Using data parameters comparisonmethod, through the acquisition of vibration and temperature data processing, inorder to determine the failure or possible failure of oil transfer pump unit. Sys temsoftware program is developed based on LabVIEW virtual technology, hardware,mobile data recorder through the LAN connections to the host, and the data todisplay in the software programs, in order to achieve real-time monitoring anddiagnosis function.Oil transfer pump safety monitoring and fault diagnosis system softwaredesign will be as a key part of this paper. Considering the site condition, technicallevel and the cost control as well as other factors such as, in the development ofthe choice of the architecture of the system, elaborated the selection of systemframework and hardware equipment selection. Based on LabVIEW virtualinstrument programming function, the realization of the system software isbroken down in two programs, and by this two programs to complete data acquisition, status monitoring and fault diagnosis analysis task.Under the protection of fault diagnosis system in monitoring and prediction,by using this system, which can realize the safe operation of oil transfer pumpequipment, and do it in a timely manner and good maintenance.
