YW-A01-type hydraulic excavator simulation training sets an experimental project? 1, hydraulic component parts of each structure and working principle to observe, disassembly experiments. ? 2, hydraulic mining machinery presentation control experiments. 3, PLC control software simulation and experimental demonstration. ? 4, a programmable logic controller (PLC) electrical control experiment: machine - electric - hydraulic integrated control experiments. ?? Second, the content of an experiment, hydraulic components of the structure and working principle of observation, disassembly Experiment 1) mapping and analysis of mechanical components;? Learning and analysis 2) hydraulic control system principles. ? 2, hydraulic mining machinery control experiments demonstrate a) mining operations, bucket and stick composite experimental work;? 2) turning operations, raise the boom while rotating platform; 3) discharge operations, stick and bucket work simultaneously height adjustable arm position;? 4) returned platform swing, boom and stick with the return to the starting position excavation. 3, programmable logic controller (PLC) electrical control experiment: machine - electric - hydraulic integrated control experiments. 1) PLC programming instructions, ladder programming learning;? 2) PLC programming software to learn and use;? 3) PLC and computer, online debugging;? 4) PLC application optimization and control solutions in the hydraulic transmission control . . ? Third, the performance and characteristics? 1, bench cold-rolled steel (and after the spray, anti-corrosion treatment) production, desktop configuration, control operations in one. 2, the electrical operating control for under-mounted, hydraulic station placed in the hydraulic master cabinet. Compact structure, coordination, arrangement beautiful, practical, for 4-6 experiments. 3, according to others scale mining machinery, all-metal construction, test mode when starting the hydraulic system to operate the machinery to work according to the experimental requirements. 4, mining machinery is produced by the physical structure and the reduction ratio of from, can truly reflect the actual working conditions of its machinery, so that students can experiment a deep understanding of the structure and working principle of the various components of their bodies. 5, experimental control with manual control and automatic control in two ways. 6, the experimental components using pressure hose, the pressure can reach 25Mpa. 7, with a three-phase leakage protection, output voltage 380V / 220V, earth leakage current exceeds 30mA to cut off the power supply; electric control DC 24V power, and with overvoltage protection to prevent damage to equipment malfunction. ? Fourth, the main technical parameters of the motor model:? Power: 1.5KW speed: 1420r / min pump models: vp12-08 rated pressure: 7Mpa Rated Flow: 8ml / rev Dimensions: 1550 × 650 × 1800mm
