【摘要】 本文从实际应用出发,以实例阐述液压油选择、液压系统散热量计算及冷却器、冷却风扇的选择、液压冷却回路设计。设计钻机要求设备紧凑、尺寸小,做成很大的油箱在结构上是不允许的,所以液压系统中产生的热量单靠油箱和元件及管件表面散热是远远不够的,这就要采用冷却器对热油进行强迫冷却,因此,液压系统中的散热设计就显得十分重要。更多还原

【Abstract】 This paper introduces the choice of hydraulic oil, hydraulic system heat dissipation calculation and choice of cooler and cooling fan, the design of hydraulic cooling circuit by specific cases from the actual application. Drilling rig design requires the compact equipment and small size, the large fuel tank design is not allowed. Therefore, it is not enough that only use pipes and tanks and component surface cooling the heat generated in hydraulic system, facing this, we should use cooler to carry the forced cooling to the heat oil.更多还原
