More Information
Summary:The utility model relates to a hydraulic-electric sequence controller for hydraulic transmission control system. The hydraulic-electric sequence controller is composed of an electro-hydraulic memory element, a hydraulic-electric conversion sequential control switch and 'or, not, forbid, and' logic elements. Because the contacts of electric conversion elements are adopted by the sequential control function, a feedback input system is connected in series with a signaling element which realizes the next program motion, and the controller has reliable performance. When the program motion of a machine tool is more than four steps, a programmer with 8 steps or 12 steps or... 4*n steps can be superimposedly composed. The utility model has the advantages of energy saving, low cost and convenient maintenance.
