Digital hydraulic valves

Digital hydraulic, fuel tanks as digital, or digital cylinder. It refers to stepper motor, hydraulic slide valve, position feedback loop combination in the design of internal hydraulic cylinder, connected to hydraulic oil source, all the functions directly through a dedicated digital controller, computer or PLC programmable logic controller A digital pulse signal to complete the length of vector control of high-tech products.
The use of characteristics: 1, can be achieved single-cylinder multi-speed, multi-location, two-cylinder or two-cylinder over a poor campaign, the completion of tracking movement.
2, dynamic, with 86-seat as a stepping motor output signal so that the hydraulic cylinder piston rod in full accordance with the stepper motor sports and exercise, that is yet further, have hundreds of thousands of tons of thrust. Therefore the use of low-power control system, would enable the large-scale machinery NC, save the direction valve, governor valves, hydraulic valves diversion regulations, and other pieces. Reduce costs. Simplify the system, narrowing the volume, reduce the accident rate.
3, the control system simple, touch-screen programming. A computer can complete the single-cylinder multi-point, multi-speed control, the multi-cylinder can also be completed simultaneously, interpolation movement. Simple, practical good. For example: the number 200 mm per second fuel tank to the forward speed of 200 mm, and then to the speed of 50 mm per second forward 200 mm, stopped two seconds, and then to the speed of 500 mm per second to return to the origin, and then stopped three seconds, the cycle 100 times to stop running, Programming is as follows: 1. Speed 200 2. G-len 200 3. Speed 50 4. G-len 200 5. Delay 2000 (ms) 6. Speed 500 7. G-len -400 8. Delay 3000 (ms) 9 . Loop 01 100 10. End.
4, a high degree of simplification of the hydraulic system, just pumps, relief valve (or digital pressure valve) can be formed to take over the use of hydraulic source, without any direction valve, the flow valve, governor valves, one-way valve, valves, and other complex synchronization Hydraulic components. These valves also omitted the installation of the integrated block, and need not trip switches, relays and other electrical components. Reduce the use of costs and maintenance costs.
5, a bus control and continuous control. Bus can be achieved in the computer control system, hydraulic machinery and other processing equipment components flexible processing unit. PIC microcontroller used to convert analog electro-hydraulic control valve of the hydraulic machinery, do not have this feature.
