Description

technical field [0001] The invention relates to a hydraulic crusher, in particular to an optimal control method for a cutter shaft of a hydraulically driven crusher. Background technique [0002] At present, crushers are becoming more and more large. The so-called large-scale refers to the increasing garbage processing capacity, torque and power. Behind the trend of large-scale crushers, the hydraulic drive system has gradually replaced the electric drive system in large-scale crushers due to its advantages such as flexible control, small footprint, fast response to forward and reverse rotation of the cutter shaft, and high power utilization. [0003] Existing technical solutions: At present, the following methods are generally adopted for the control of the cutter shaft of hydraulically driven crushers: set the maximum system pressure (that is, the pressure on the hydraulic motor) and about 3 pressure intervals, and different pressure intervals correspond to corresponding n...
