Abstract: In order to solve the difficulties in controlling the turning angular velocity leading to the angle measurement ferrying data with the corresponding problem by using eddy current sensor and new type of grating sensor device,using an adaptive variable speed barring consecutive ferry method is used,and the development of analysis and processing system is based on Matlab,the accurate calculation of the pump shaft fixed point on the ferry,and the corresponding axis adjustment scheme is given for your reference. Relevant achievements can be applied to turning and swing measurement of large vertical pump stations.
