低温钻机液压系统的研制
Development of hydraulic system for low-temperature drilling rig
摘要
Abstract
A low-temperature drilling rig has been developed to meet the needs of mineral resource exploration and scientific drilling in extremely cold regions.Based on the actual operating conditions and application requirements of drilling rig in extreme environment as low as-40℃,a dedicated hydraulic system was designed and developed to match it.This paper mainly discusses the circuit composition and working principle of the hydraulic system of low-temperature drilling rig,and provides a detailed introduction to fine drilling in ice layers,adaptive optimization in low-temperature environments and all-weather operation capabilities in extremely cold environments.On site application has shown that the hydraulic system has stable and reliable performance under extremely low temperatures,and all performance indicators have met the design requirements.This low temperature drilling rig has the characteristics of high operation efficiency,high degree of automation and strong environmental adaptability,which meet the requirements of resource exploration in extremely cold regions.关键词
