摘要
本文结合SPZ型深孔喷射钻具的研制与实验,着重分析了喷射效应在钻削过程中的应用,建立了流体系统的数学关系式,为深孔喷射钻的设计提供了必要的理论依据。
This paper analyses the application of ejector effect in process of drilling and suggests the mathematics model of fluid system based on the study of SPZ type deephole ejector drill. The model provides the necessary theoretical basis for designing deephole ejector drill.
