Abstract
A large-axis peristaltic detection method applicable to a power station unit is provided. The method comprises the following steps in use: 1) obtaining the respective number A of speed measuring toothed belts on a toothed disc and empty grooves in a power station unit speed control system, the length B of a single speed measuring toothed belt, and the length C of a single empty groove; 2)solving alarge-axis center angle value phi corresponding to the arc length of a toothed belt plus the arc length of an empty groove; 3) solving the large-axis center angle value corresponding to the arc length of a single toothed disc and the large-axis center angle value corresponding to the arc length of the single empty groove; and 4) determining the number of to-be-installed sensor probes through calculation, and arranging the sensor probes continuously around the toothed disc and at a distance D. In order to accurately, precisely and effectively monitor the peristaltic motion of a large-scale power station unit, the present invention provides a large-axis peristaltic detection method applicable to a power station unit.
