旋挖钻机动力系统功率匹配技术的应用

Application of Power Matching Technology in Power System of Rotary Drilling Rig

旋挖钻机动力系统是发动机和液压传动相结合的统一体,单纯液压系统的节能控制并不能取得较好的整机节能效果,发动机的控制也对整机节能性有很大影响。对发动机与液压系统的功率匹配控制进行了研究,提出了功率极限载荷控制技术,并在NR220旋挖钻机上应用了德国力士乐公司的电子功率极限负荷控制技术,收到了良好的效果,保证了旋挖钻机的高效节能和对各种工作环境的适应能力。

Rotary drilling rig power system is a unity, which combined engine with hydraulic transmission. Only energy saving of hydraulic system could not obtain ideal energy saving effects of the whole machine, and engine control had great influences on the whole machine saving. The paper discussed power-matching control of engine and hydraulic system, put forward power-load limit control technology, and introduced the application of electronic power-load limit control technology of Bosch Rexroth Company in NR220 rotary drilling rig.
