In a unidirectional motor circuit with a braking relief valve, the relief valve open to Supply fluid to the inlet of the motor to avoid cavitation Relieve fluid to tank Supply fluid to the outlet of the motor to assist braking An accumulator used to store fluid energy The Hydraulic Braking Design rule states that you should O Provide a return line for the fluid to tank Never supply full system pressure to a hydraulic brake @ Always over-design a...
The motor is designed to operate as slow as 1 rpm and is capable of developing a high constant torque. HSKT O LSHT OHTLS LHST The advantage of a balanced vane motor is The side load on the shaft is reduced The vanes wear evenly extending the life of the motor O The weight to horsepower ratio That fewer vanes are required compared to the unbalanced vane motor In an external gear motor, one gear attaches to a shaft while...

DATA FOR THE QUESTION IS :
Question #1 10 marks Draw a simple hydraulic Circuit which will operate a hydraulic cylinder of a machine. The load during forward stroke is 15 KN and that during return stroke is approximately 9.5 KN. The forward and return speeds are about 3.5 m/min and 5.5 m/min respectively. The total stroke of the cylinder is 400 mm. A provision is required to hold the cylinder anywhere in between the end positions. Select the different...
