Abstract


In addition to the scales pump unit is a structure in the form of large rotating machinery and uninterrupted operation of the production characteristics for high pressure , developed a set of high-pressure addition to scales pump unit online monitoring and fault diagnosis system . That the system can achieve real-time data acquisition and analysis processing in monitoring pump operating status at the same time , running interface scheduling, configuration parameter settings , online printing and other functions . In addition , the system's precision diagnostics, including historical data playback analysis , trend analysis , time domain analysis , spectral analysis, pump fault type , location , severity , and trends analysis and forecasting . During the test run the system , the vibration of the pump rotor field measurement, a good outcome of the trial . In this paper, the main cause of pump vibration to the pump system failure modes and vibration mechanism , pay to the gear pump system , gear fault signal analysis . In this paper, the method of fault diagnosis , rotor dynamics model and the motion characteristics of the vibration signal also made ??some research . In conclusion, the article describes the High Pressure scales pump online monitoring and diagnosis system hardware and software development in key technologies . The hardware implementation details of the hardware design of the overall program , the use of the principle of selection and calibration of the sensor , the alarm system design ; software implementation of software functional design and user interface design . The contrast of this article analyzes the status and development prospects of predictive maintenance system in the domestic and foreign enterprises ; rotating machinery fault diagnosis model is established on the basis of the common faults of the high - pressure pump type analyzed . The system comes from engineering practice , the development of the entire system from a user perspective . The system is easy to operate, detection speed, high accuracy and judgment . System through continuous improvement , the function has been tested to meet the user's requirements .
