| Abstract: | In this paper ,the writer puts forward the measures to increase the speed and to lessen the hydraulic shock in the hydraulic system with high pressure and large flow and also presents some ideas of enhancing the service life of the hydraulic elements. Besides, applying the proportional control technique in the large hot work production line makes the manipulators run quick and smooth, obtaining the desired results. |
