MR103M Electro Hydraulic Workbench for Training Double Sided Vocational Training Equipment Teaching Model Hydraulic Trainer 1 Product overview 1.1 Overview This hydraulic training device adopts the open structure operation panel design according to the syllabus requirements of mechanical and electrical integration of colleges and universities for gas, electricity and hydraulic control, and combines the advantages of pneumatic relay control and hydraulic relay control experimental equipment. Various hydraulic components can be flexibly installed on the operation panel. All joints adopt open-close quick joints at both ends, which solves the problem of oil leakage in the hydraulic circuit, is convenient and durable, reduces losses and is also conducive to maintaining environmental sanitation. Arbitrary combination of various components to form a hydraulic system with certain functions, with strong practicality. 1.2 Features (1) The equipment is composed of a high-strength sheet metal frame, which is beautiful and durable. The bottom is equipped with universal wheels, which can be easily moved; it is equipped with a cabinet for storing tools and devices, and the hydraulic station is integrated in the lower part of the equipment; various hydraulic valve blocks are fixed The base plate adopts special base plate profile, the groove interval of the panel is 25mm, and various parts can be easily plugged in and unplugged on it; the upper part of the electronic control hanging box is placed, the whole is compact. (2) Equipped with industrial hydraulic valves, the maximum working pressure can reach 35Mpa. Each hydraulic component is equipped with an oil circuit transition base plate, which can be conveniently and freely placed on the panel. The oil circuit lap connection adopts open-close quick-change joints, which is convenient for disassembly and connection, does not leak oil, reduces loss and also helps maintain environmental sanitation. 2 Performance parameters (1) Input power: AC: 380V (2) Experimental table size: 1600mm×1000mm×1680mm (3) Aluminum alloy panel size: 1200 (length) × 750 (width) (4) Groove interval: 25mm (5) Specifications: Cabinet: 1 (6) Desktop structure: 1 (7) Casters with split grooves: 4 (8) Safety limit speed range: 1000-1500 rpm (9) When the hydraulic pump is working, the noise at a distance of 1.5m from the hydraulic platform is less than or equal to 58dB0 (10) Demonstration experiment requires only 4-6Mpa for fluid flow pressure 3.1 Electrical control unit The electrical control unit includes master control switch hanging box, PLC hanging box, DC power supply hanging box, relay hanging box, button hanging box and emergency stop hanging box. 3.2 Training platform The training platform is composed of aluminum profile and aluminum alloy base plate, which can be moved and positioned flexibly. The actuator control box is installed on the base plate, which is beautiful and generous. 3.3 Power configuration Three-phase five-wire power input, protected by insurance, is equipped with a main power switch. In an emergency, turn off the main power switch to stop the execution object. 3.4 Hydraulic components Picture, model and Chinese name of hydraulic components. 1.Direct-acting relief valve Three-position four-way solenoid directional valve O type 3.Three-position four-way solenoid directional valve M type 4.Three-position four-way solenoid directional valve H type 5.Three-position four-way solenoid directional valve Y type 6.Stroke valve 4WMR6D50B Two-position four-way solenoid directional valve 4WED-6X/ED24 8.Speed control valve 2FRM5-31B/10Q 9.Pilot operated relief valve DB10-1-50B/100 Pilot-operated sequence valve DZ10-1-30B/210M Pilot operated check valve SV10PA1-30B Pilot operated pressure reducing valve DR10-1-50B/200Y Pressure switch HED40P15B/100LZ14S Manual reversing valve 4WMM6D50B Glycerin pressure gauge 16.Fast oil divider valve 17.Three links Five links Tubing 19.Hydraulic power station Hydraulic cylinder 21.Inductive sensor 22.Photoelectric Sensors 23.Capacitive sensor 24.Limit switch 4 Experiment content: Experiment 1.
