Calculate sizing of the hydraulic pump

The sizing of the pump can be obtained from the following specification.1. Flow. The need for oil. 2. The pressure being used. 3. Size electric motors. Or engine driving the pump. Suppose to 200 bar maximum pressure cylinder size ID 100 mm. Speed of movement of the cylinder was 3 cm / sec. A = 10 x 10 x 0.785 = 78.5 cm2. V = 3 cm / sec. Q = V x A = 3 cm / sec x 78.5 cm2 = 235.5 cm3 / sec = 14.13 L / min. Rotate pump drive motor speed 1450 rpm. Therefore, …

Primer of mechanical spring types

Spring. Springs are used in many machines such as the control force arising from impact load acts ginger. Control the level of vibration. Force and motion control components of energy storage springs are generally classified according to several categories, such as by shape. Classified according to the acting load. Type of the spring by the burden of action. Spring pressure (Compression spring). Used for pressure parts such as choke up pressure on car Spring Tension (Tension spring).   For example, the tension spring balance.   Coil springs torsion (Torsion spring). In the burden caused by torque in the axis, such as …
