声频振动钻机的流量与负载同步结构概述

Overview of flow and load synchronization structure based on sonic drilling rig

声频振动钻机由于其不使用钻井液、对地层无污染等优点,广泛应用于环境调查领域。声频钻机的双偏心轴若在高速下达到同步状态能够极大地提高钻进效率。从常见的流量与负载同步结构与原理以及其同步精度和优缺点等方面系统分析了声频振动钻机双偏心轴的同步机理,提出了解决高转速下的同步思路,以期为其完善和提升提供参考。

Sonic drilling rig is widely used in the field of environmental investigation because it does not use drilling fluid and has no pollution to the formation.The drilling efficiency can be greatly improved if the double eccentric shafts of the sonic drilling rig are synchronized at high speed.This thesis systematically analyzes the synchronization mechanism of double eccentric shafts of sonic drilling rig from the common structure and principle of flow and load synchronization,as well as its synchronization accuracy,advantages and disadvantages,and puts forward the synchronization idea at high speed,so as to provide reference for its perfection and promotion.
