Abstract
In view of the problems in the operation of a speed governor
the logic of high-speed switch valve jam is analyzed
and the logic risk of governor hydraulic control circuit is enumerated. The logic optimization measures are put forward and the mechanical logic of the circuit is blocked to prevent the pressure oil from returning directly to the oil tank
which improves the operation reliability of the speed governor.
