摘　　要：管道输送危险废物到回转窑焚烧是处理危险废物最有效的方法,固体泵容积效率是影响整个管道输送能力的主要因素之一。通过阐述固体泵与无轴双螺旋输送机的工作原理,基于Modbus工业现场总线协议,采用PLC同步采集活塞位置信号和物料液压缸压力信号等,得出了研究容积效率的测试方法,试验研究了电动机转速及无轴双螺旋输送机转数对固体泵容积效率的影响,从而得出在提高泵送能力的情况下电动机的最佳转速与时间。Pipeline transportation of hazardous waste to the rotary kiln for incineration is the most effective way to deal with hazardous waste,and the volumetric efficiency of the solid pump affects the conveying capacity of whole pipeline.Firstly,the working principle of the solid pump and the shaftless double screw conveyer was expounded,and then the method of testing the volumetric efficiency was obtained via PLC collecting the piston position signal and the material cylinder pressure signal based on Modbus industrial field bus protocol.Finally,the test for the influence of the motor velocity and the shaftless double screw conveyer on the volumetric efficiency of the solid pump was conducted,thus the optimal velocity and duration of the motor were identified.
