液压剪循环冷却系统的改进

Modification of the Circulation Cooling System of the Hydraulic Shear

液压系统以其体积小、结构紧凑、工作平稳、易于实现过载保护等优点得到广泛采用。在实际应用中,大多数液压系统的发热严重影响着控制精度的提高。必须认真分析其产生的原因,减少系统的溢流损失和压力损失,提高系统效率才能从根本上控制系统的发热。合理的选择循冷却系统对整个液压系统的热平衡十分重要,对主机的正常使用起着至关重要的作用。

Hydraulic systems have been extensively used because of the small volume and the compact structure. The system can run smoothly and steadily and protect components under overloading. In practical appliance, heating in a hydraulic system affects the control. So we have to analysis the reason of the heating carefully and reduce the pressure loss and pressure-relief loss in a hydraulic system, in order to increase the efficiency of system. Choosing the circulation cooling system suitably is very important for the machine.
