YZ-A01-type hydraulic loaders simulation training bench? An experimental project? 1, hydraulic component parts of each structure and working principle to observe, disassembly experiments. ? 2, hydraulic loading 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 loading machine control experiments demonstrate a) loading operations, after loading the bucket cylinder extended arm thing, reverse bucket, boom lifting;? 2) unloading operations, bucket unloading material (Rocker retracts, the bucket steering), the boom-down. 3, programmable logic controller (PLC) electrical control experiment: machine - electric - hydraulic integrated control experiments. ? 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, loading machinery by others scale all-metal construction, test mode when starting the hydraulic system to operate machinery to work according to the experimental requirements. 4, loading machine is produced by the structure and reduce the proportion made in kind, 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 Model:? M3P4H523 power: 1.5KW speed: 1420r / min pump models vp12-08 rated pressure: 7Mpa Rated Flow: 8ml / rev Dimensions: 1550 × 650 × 1800mm
