I. Experiment project

1, hydraulic drive all the components structure and working principle, can tear open outfit experiment.

2, hydraulic mining machinery demonstration control experiment.

3, PLC software simulation demonstration and control experiment.

4, programmable controller (PLC) electric control experiment: mechanical, electrical and hydraulic integrated control experiment.

II. Experiment content

1 Hydraulic transmission components structure and working principle, can tear open outfit experiment

2 PLC in hydraulic drive control and application of the optimization of the control scheme.

III.Performance and features

1 Test bench, the cold rolled steel sheet (and after coating, anticorrosive processing) production, table structure, control operation at an organic whole.

2 Electrical operation control for underneath type, hydraulic station placed in hydraulic station in the Lord. Compact structure, coordination, layout beautiful and easy, practical strong, for 4-6 people experiment.

3 Mining machinery by physical scaling of all metal structure, experiment start hydraulic system according to the requirement of experiment mode to operate machinery for work.

4 Mining machinery is according to the physical structure and scale down production and become, can truly reflect the mechanical actual working condition, so that the students can in the deep understanding of the mechanism of each component of the structure and working principle.

5 Experiment control using manual control and automatic control in two ways.

6 Experimental unit using pressure hose, and the pressure can reach 25 mpa.

7 With three phase leakage protection, output voltage 380 v / 220 v, earth leakage current more than 30 ma is cut off power supply; Electrical control adopts dc 24 v power supply, and with overvoltage protection, prevent maloperation damage to equipment.
