PLC Hydraulic Excavator Training System
PLC Hydraulic Excavator Training System is an intuitive and visual platform for hydraulic circuit design and hydraulic control demonstrating.The internal structure and working principle of various hydraulic components is vivid and intuitive because all transparent hydraulic components are made of transparent plexiglass according to industrial standard.PLC Hydraulic Excavator Training System enable students to learn the structure,work principle and function of each single hydraulic components.Meanwhile,Students can constitute hydraulic circuits to survey movement situation of spool in the loop tank and flow direction of fluid in the spool body.The excavator on this PLC Hydraulic Excavator Training System is used to simulate the action of mining,discharging,lifting,etc. Students learn hydraulic system, its working and control principle of an excavator.PLC Hydraulic Excavator Training System meets different hydraulic disciplines.
Features
1.The training panel is T-slot, and all hydraulic components adopts rapid joint for easy operation.
2.The hydraulic components are made of transparent plexiglass,the inner structure and the working process of the hydraulic components are vividly demonstrated.
3.Circuit experiment adopts leak proof fast inserted interface to make experiment circuit assembly simple, quick and clean.
4.The are two control methods:PLC control and relay control.
