Hydraulic Cylinder Hyspecs Hydraulics Australia If the valve spool moves a little bit, the valve flows a little bit. pressure compensation, load sensing or sophisticated electronic control lend the proportional valve superior performance for controlling cylinder speed. no matter the control method, providing your cylinders with a method to control speed is always helpful.

Schematic Diagram Of Hydraulic System Of Hydraulic Cylinder Unit 1 In order to understand how intensification takes place we must first understand one of the basic fundamentals of fluid power: pressure x area = force (force area = pressure) a typical single rod hydraulic cylinder, such as the one illustrated above, extends and retracts by applying hydraulic pressure to either the cap end (extend side) or rod. When a hydraulic system is supplied by a pressure compensating pump, flow controls may be connected in either a meter in or meter out configuration. when metering the flow going into a cylinder (meter in), no pressure intensification will occur. however, this configuration provides less control over the cylinder speed due to overrunning loads. Intensifier circuit using standard cylinders. the schematic diagram in figures 13 6 through 13 9 suggests how to use standard cylinders as an air hydraulic intensifier. this is a quick way to get high ratio intensification for a rush job. a 6 in. bore air cylinder driving a 1.5 in. bore hydraulic cylinder gives an intensification ratio of 16:1. Figure 11 26. meter in flow control circuit with motor type flow divider to minimize heat generation. (shown with cylinder extending at slow speed). figure 11 26 shows a 3 speed flow control circuit using a rotary flow divider. here the cylinder is extending slow speed. with the circuit set up as shown, it defaults to slow speed.
