| Abstract: | In order to save energy, reduce temperature rise, prolong the service hours of the hydraulic fluids and improve the working reliability, energy saving control is used in most large power hydraulic systems. An energy saving system with a self regulated and servo valve controlled variable displacement pump is described, which is of the electro hydraulic type compound control without an external auxiliary oil source. It has been used in a large loading system with non linear variable gain compensation to improve its dynamic performance. Test results are given. |
