摘要
以长江及沿海航道铺排工程船(长雁1号)液压系统的工程项目为背景,在分析和研究吸扬14号绞吸式挖泥船电液比例控制系统的基础上,对原系统进行改进,不仅降低液压系统的能耗,而且还实现了对移船马达速度的准确控制,避免了移船马达速度的不稳定。
In light of the requirements of hydraulic system design for laying engineering vessel in the Changjiang river and coastwise sea lane,the electro-hydraulic proportional control system of a certain cutter-suction dredge was analyzed in order to develop a novel electro-hydraulic proportional control system.The system follows the developing directions of the electro-hydraulic proportional control techniques and results two innovative technological achievements in speed exact control of hydraulic motor and energy-saving.
