Hydraulic drive
Abstract:
The invention relates to engineering hydraulics, in particular to hydraulic drives with closed working fluid circulation. The hydraulic drive contains a hydraulic accumulator connected with a drive motor. The hydraulic pump is connected through pressure and drainage pipelines to a hydraulic distributor connected through pressure-drainage pipelines to a double-acting hydraulic motor with piston and rods. Between the pressure and drainage pipelines is connected a check valve. The hydraulic flow distributor, is made crane-type, three-position, six-way, consisting of a cylindrical body closed on one side with a cover, the other side with a pressure washer, on the shaft is mounted a control lever. In the cylindrical body and the shaft are made in two levels create alternately pressure and drainage flow passages. The hydraulic drive has a wide range of manufacturing and operating capabilities, large capacity and speed, positional accuracy of the actuators, compactness, low weight and high reliability.
