深海笼捕起倒式液压起笼机研制报告

笼捕作业是90年代引进并兴起的海洋捕捞作业方式,但作业所需的起笼机械尚未配套。“起倒式液压起笼机”设计拉力2.5千牛顿、线速度20—60m/min,绞盘直径250mm,液压系统额定工作压力10兆帕,并有可起倒、无级调速及过载安全保护等性能,可适应深海作业要求。

The dynamic running law study on driving system of hydraulic winder

Dynamic running law of the hydraulic driving system decides the hoisting cage velocity curve in a hoisting cycle and is decided by the characteristic of the hydraulic driving system and by the operating speed of hoist driver. The paper studies the dynamic running law of hydraulic driving system, analyses the influence of driver operating speed on the dynamic running characteristic, and points out the reasonable driver operating speed to control the dynamic stress in rope and to reduce the oscillation of rope system.
