What is a double acting driver?
Double acting driver is a mechanical device designed to supply driven two -way control for secondary mechanisms. This is, unlike drives and solenoids with one event or spring return, which have a driven move in only one direction and rely on a secondary energy source to reset or return the driver. The double acting driver is usually powered by electric engines or compressed oil and gas. Electrically controlled double action drives give their two -way power using the engine conversion circuit. Compressed gas and oil controls have contradictory inlet valves that direct the motif agent to one or the other to the drive mechanism.
drives are devices used to operate a machine or mechanism remotely by delivery of a predetermined range of output movement. This movement is generally divided into two strikes in contradictory directions. These may be moves of activation and recovery or two -way operating moves. Ivoation and recovery Ansystems are wellIllustrated by a metal pressing machine where it is died down for activation stroke and restored or returned to the neutral position of readiness for the next cycle. Output of two -way enforcement can be seen in the valve drive that turns in one direction to open the valve and in the opposite direction to close it.
There are many different categories of drivers, with the most important types of double action or one acting drivers. The defining characteristic between the two categories is whether the driver gives the power for both directions of its working range or only one. One actor will only give half of its control range. This type of driver is generally used where torque load is only found on activation - for example, on the above metal - and the opposite hundred is required only to return the driver to the neutral position. DFlower examples of these are spring return and solenoid drivers, where the driver is reset with spring voltage after completion of the driven stroke.
On the other hand, the double acting driver is powered on both halves of its cycle and is ideal for applications that have a high torque load in both directions, such as the above valve driver. Achieving this double action in an electrically controlled double acting driver simply includes reversing the rotary direction of the drive engine. Drives driven by compressed gas or oil are a little more complicated and require a set of directional valves for power and two input ports on the drive mechanism. When the driver is driven in one direction, the valves send gas or oil to one side of the piston or shoulder blade in the control mechanism that drives it in a certain direction. When the reverse draft of re -directional valves directs gas or oil to the other side of the shoulder blade or piston that effectively reverses its output direction.
