Abstract: In order to enhance the intelligent level of horizontal vibrating centrifuge, and make up the deficiencies of its existing monitoring aystems, which are imperfect in monitoring means and inconvenient in adjustment of operating parameters, optimum design is accordingly made of the lubrication, vibration and parameters adjustment systems of the centrifuge by using signal acquisition, data processing, PLC programming and frequency-conversion adjustment technologies. It is intended to enable the monitoring systems to realize early warning and diagnosis and online adjustment of parameters. Through the optimum design, in addition to the improvement of the functions of lubrication and vibration systems in making self-diagnosis and early warning, the operating parameters are made easy to adjust or select according to property of coal for meeting the needs of different users.
