BEARING SYSTEM FOR DEVELOPMENT DRILLING GAS COMPRESSOR AND DEVELOPMENT DRILLING GAS COMPRESSION SYSTEM, AND MAGNETIC BEARING CONTROL METHOD FOR DEVELOPMENT DRILLING GAS COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a bearing system for development drilling gas compressor showing a superior tracking in control of a magnetic bearing.;SOLUTION: A bearing system for a bearing system of development drilling gas compressor comprises a state quantity sensor for detecting an amount of state of the development drilling gas flowing into the compressor, a magnetic bearing for supporting a rotating shaft of the compressor, a displacement sensor for detecting a relative displacement between the magnetic bearing and the rotating shaft and a controller constituted to control supplied current to a coil for the magnetic bearing on the basis of deviation between the detected result of the displacement sensor and a target value of the relative displacement, the controller is constituted to adjust control parameters at the controller on the basis of the result of detection of state amount sensor.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
