YD-C type hydraulic transmission practical overview of the comprehensive test-bed: YD- type push Hydraulic modular bench bench is designed according to the characteristics of modern teaching and the latest hydraulic transmission syllabus requirements. It uses advanced Rexroth hydraulic components and the unique modular technology, constitutes a convenient docking system portfolio to meet the universities, secondary schools and vocational technical schools require students to experiment teaching Hydraulic tutorial; reach students hands-on design and comprehensive ability to improve and strengthen the purpose of students' innovative design capabilities. First, the main features: 1. The system used in all standard industrial hydraulic components, the use of safe, reliable, close to industrialization. 2. Quick and reliable connection, special sealing interface, ensuring easy assembly experiment quick disconnect not leak, clean. 3. accurate measuring instruments and convenient measurement, using a simple, accurate and reliable measurements. Second, the common teaching circuit hydraulic principles: 1, the governor and the inlet throttle valve speed governor. 2, pump performance test (pump flow characteristics, volumetric efficiency and overall efficiency). 3, relief static and dynamic experiments (opening and closing characteristics, pressure overshoot characteristic). 4, the throttle valve speed performance test speed (inlet throttle control, throttle governor back to the oil bypass system operating characteristics). 5, the hydraulic system efficiency experiments. ④ students to design, expand the hydraulic circuit assembly up to 20 kinds of experiments over two, bench consisting of:. ① laboratory bench test bench by iron and aluminum body panels type (T-type hook slot), and the like. Table dimensions: length × width × height = 1600mm × 700mm × 1800mm (about 250kg after packaging) ② pump station system rated working pressure: 6.3Mpa. (Maximum to 7Mpa) ⑴ motor - pump unit (1 station) variable vane pump - Motor 1 Taiwan: variable vane pump: one-way, nominal displacement 6.67mL / r, the volumetric efficiency of 90%; Motor: Three-phase AC voltage power 2HP 4P, speed 1450r / min; ⑵ tank: Nominal volume 45L; with liquid level, oil temperature gauge, oil, back to the oil filter, valve and other hydraulic components used ③ Dr. Rexroth technology components based configure See configuration list. Each is equipped with the oil hydraulic components floor transition, can be easily and freely hydraulic components mounted on aluminum alloy type panel.
