Abstract
The invention relates to a two-channel vibration swing-range monitoring control loop. Various stability parameter data are obtained through the fact that the parameters of vibration, a swing range, pressure pulsation and the like of a hydraulic turbine set in operation are conducted on-line monitoring and the parameters represent the stability of the hydraulic turbine set, the current operation status of the hydraulic turbine set is analyzed according to the stability parameter data to monitor the slow changing process of the faults of the hydraulic turbine set, so that good basis is offered for the maintenance of the hydraulic turbine set status, and at the same time reliable information for the operation and dispatching of the hydraulic turbine set is supplied. The two-channel vibration swing-range monitoring control loop is characterized in that a data acquisition circuit, an analog-to-digital (A/D) switching circuit, a display and input module and a storage module are respectively connected with a controller, a sensor group is sequentially connected with the date acquisition circuit and the A/D switching circuit, and the controller is connected with an alarm module. The two-channel vibration swing-range monitoring control loop monitors the radial vibration of a main shaft of the hydraulic turbine set in the X and Y directions on line, can monitor the vibration of a vertical channel and the vibration of a horizontal channel on line after the two-channel vibration swing-range monitoring control loop is connected with a low frequency vibration sensor, and the two-channel vibration swing-range monitoring control loop is high in reliability and easy and convenient to maintain and change.
Description
Technical field
The present invention relates to a kind of two-channel vibrating functional throw Monitoring and Controlling loop.
Background technology
