Rotary Drilling Rig precision rotary control driven by Digital Hydraulic Motor / 旋挖钻数字液压马达精密回转控制 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NtdcpITSzgQ.html Precision Rotation Control of Digital Hydraulic Motor The rotary drilling rigging requires frequent rotation and accurate positioning, and the rotary inertia reaches tens of tons-meters. At present, there is no automatic control system, which can only be realized through the experience accumulated by the operator for many years and with highly centralized control. The rotary drilling rig driven by AEMETEC's digital hydraulic motor realizes high precision repeated positioning and slow start and slow stop, which not only greatly improves the operation accuracy and efficiency, but also reduces the fault and fuel consumption, and cooperates with the digital hydraulic motor crawler control, Combined with DGPS, automatic drilling operation can be realized. ▉ Rotation error: + /-0.2 degrees ▉ Rotation speed: + /-0.2 ~ 60 degrees / second 数字液压马达精密上装回转控制 旋挖钻由于需要不断将钻取的土石从孔洞内取出，因而要求上装回转频繁工作，且需要实现数十吨米大惯量大扭矩平顺启停和精准对位。以往这是一个没有攻克的难题，只能通过操作手多年积累的经验并配合高度集中的操控，方可实现对旋挖钻机的高效安全操控。 数字液压马达驱动旋挖钻机上装回转实现高精度重复定位和缓启缓停，不仅让昨夜精度、效率大幅提升，还降低了故障、燃油消耗等，配合数字液压马达驱动的履带行走控制，结合DGPS便可实现自动钻孔作业。
