Research on Digital Flow Control Technology for Mine-used Emulsion Pump
摘要
Abstract
To address the dynamic and efficient supply-demand matching between fully-mechanized-mining-equipment and fluid supply systems in fully mechanized coal mining faces,this study proposes a digital flow control technology to achieve on-demand fluid supply in pump stations.Firstly,the working principle of digital flow control technology is elaborated,and an actuator work strategy compatible with the flow distribution characteristics of a 5-plunger pump is formulated.Secondly,digital flow control schemes are systematically summarized.Finally,the optimal control scheme is selected,and its reliability is verified through simulation.The results indicate that the 5-plunger emulsion pump has 7 possible digital flow control schemes,with the number of engaged actuators exhibiting a negative correlation with flow pulsation rates.Depending on the scheme,the control intervals are either[0,π]or[0,3π/5),enabling a flow adjustment range of 38%~100%.This approach not only meets on-demand fluid supply requirements but also minimizes flow pulsation,providing valuable insights for intelligent constant-pressure liquid supply technologies in fully-mechanized-mining-equipment.关键词
