Hydraulic teaching test-bed implementation of the structural design of devices
The design of the hydraulic design of the main test-bed implementation of the teaching device hydraulic cylinder, hydraulic outlined the structure of test-bed teaching, principles and developments. Thesis combined with the current test-bed hydraulic teaching the development trend of teaching hydraulic characteristics and requirements, determine the work of the hydraulic cylinder pressure. According to the work pressure on the hydraulic cylinder the size of the various components are calculated and the structure of the selected connection identified the structure of hydraulic cylinders. At the same time, also considered among the components of hydraulic cylinder seal selection and design. Finally, taking into account the oil out of the mouth of the pipe connection of hydraulic cylinder design and the exhaust device, the final completion of the overall design of hydraulic cylinder. Designed hydraulic cylinder affordable, suitable for medium and low pressure hydraulic systems, and facilitate the dismantling and assembly are suitable for the use of hydraulic teaching to meet students and teachers to carry out the requirements of hydraulic experiments.
Keywords: hydraulic cylinder hydraulic test-bed design of low-hydraulic system
