漂浮取水泵液压驱动系统方案设计及性能校核

Scheme Design and Performance Verification of Hydraulic Driving System for Floating Water Pump

为了研究漂浮取水泵的液压驱动系统,该文以功能需求为牵引,对其液压驱动系统进行方案设计,绘制了液压驱动原理图,对液压泵和液压马达进行选型计算,对系统压力损失和发热温升进行了校核。结果表明,液压马达和液压泵的选型符合条件;液压泵提供的系统工作压力大于管路的总压力损失,液压系统能正常工作;在液压系统中增设风冷器,改善了系统的散热条件,在保证系统热平衡的同时,又减小了液压油箱的体积,使系统装备结构紧凑,便于轻便机动。

In order to study hydraulic diving system of floating water pump,based on the functional requirements,the paper designs the scheme of hydraulic driving system,draws the hydraulic driving schematic diagram,designs and selects the hydraulic motor and pump and conducts the verification of pressure loss and heating and temperature rise.The result shows that model selections of hydraulic motor and pump are correct.
