1. Demonstration control experiment of hydraulic loading machinery
1) For loading operation, after the bucket is loaded, the rocker cylinder extends to make the bucket reverse and the boom lifts;
2) Unloading operation, bucket unloading (the rocker arm retracts to make the bucket turn), and the boom descends.
2. Programmable controller (PLC) electrical control experiment: machine-electric-hydraulic integrated control experiment.
1) PLC instruction programming, ladder diagram programming learning;
2) Learning and using PLC programming software;
3) Communication and online deb ing between PLC and computer;
4) The application of PLC in hydraulic drive control and the optimization of the control scheme.
