摘要
传统混砂装置由柴油发动机驱动液压系统,电控液完成压裂混砂工艺,噪声大、排放高、效率低、控制系统复杂且压裂液密度、添加剂比例等作业参数的控制精度低,对施工作业的质量和可靠性影响较大。笔者重点阐述变频电机组驱动技术方案,通过一组变频电机直接驱动吸入、排出、搅拌、输砂及添加剂机械装置,对电机转速进行变频矢量控制,达到压裂基液、支撑剂及添加剂的高质量混配。此技术方案的实施对大排量混砂装置实现节能减排、降低生产成本及提升作业效率与作业质量具有重要实际意义。
In the traditional fracturing blender device,the hydraulic system is driven by diesel engine,and the electronic control fluid is applied to complete the fracturing sand mixing process,which has great impact on quality and reliability of the construction operation due to the large noise,high emission,low efficiency and complex control system,and the control accuracy of the operation parameters such as the fracturing fluid density and the additives proportion is low.In this paper,a group of mechanical devices of suction,discharge,agitation,sand transportation and additives are directly driven by a frequency conversion motor,and the drive technical scheme of the frequency conversion motor is established.The motor speed is controlled by frequency conversion vector so as to achieve high-quality mixing of fracturing base fluid,proppant and additives.The design and analysis of this technical scheme is of great practical significance to the realization of energy saving and emission reduction,production cost reduction and improvement of the operation efficiency and quality of large displacement sand mixing device.
