摘要 为获得粒子冲击钻井技术中关键设备钢球螺旋输送机输送量计算的经验公式,对影响输送量的相关因素如螺槽深度、螺杆和筒壁表面质量、物料粒径大小、螺杆与筒壁的间隙等因素,进行了相关的试验研究。试验结果表明:输送能力随着螺槽深度的增加而增强,筒壁和螺杆表面质量的高低对球形物料输送能力的影响很小,粒径大小和颗粒表面光滑程度对输送能力有一定的影响;螺杆与筒壁的间隙越大,输送能力越差。最终根据试验结果,得出钢球螺旋输送机的输送量计算的经验公式,并通过粒子反流试验装置中的钢球螺旋输送机进行了验证,可为后续装置的应用设计和设备制造提供指导。 To obtain empirical formula for calculating the conveying capacity of steel ball screw conveyor in particle impact drilling technology project,relevant tests and research for factors impacting conveying capacity are performed such as depth of screw groove,surface quality of screw and cylinder wall,material size,clearance between screw and cylinder wall,etc.Test results show that conveying capacity increases with the depth increase of screw groove,while surface quality level of screw and cylinder wall takes little impact on conveying capacity;grain size and particle surface smoothness have certain impact on the conveying capacity;and the bigger the clearance between screw and cylinder wall,the lower the conveying capacity.According to the final test results,an empirical formula for calculating the conveying capacity of steel ball screw conveyor is obtained,which is verified with the steel ball screw conveyor in the particle reverse flow test device,providing provide guidance to application design of successive device and equipment production.
