发明名称 ELECTRONIC TORQUE AND PRESSURE CONTROL FOR LOAD SENSING PUMPS
摘要 A pump control system, comprising: a motor (12) configured to drive a pump (14); a pressure relief valve (22) in fluid communication with the pump (14); a torque control valve (32) connected to a swashplate of the pump (14) and in fluid communication with the pressure relief valve (22); a swashplate angle sensor (36) connected to the swashplate (34); and a computer (40) connected to the swashplate angle sensor (36) and the pressure relief valve (22) wherein the computer (40) controls the pressure relief valve (22) based upon swashplate displacement to achieve maximum system pressure. The corresponding method of controlling is also disclosed.
