摘要： A system for the transport of high solids sludge includes a positive displacement pump for pumping sludge through a pipeline. The volume of sludge transported is accurately measured by determining the fill percentage by using a material flow signal, measured time intervals, hydraulic fluid pressure, or hydraulic fluid flow rate during each pumping cycle.

摘要： The present invention is a sludge pump system which includes a means for monitoring operation of a sludge pump. The sludge pump includes a material cylinder and a piston moveable in the material cylinder. A pump drive moves the piston during working cycles which include a pumping stroke and a filling stroke. A pump valve mechanism connects the material cylinder to an outlet during pumping strokes and connects the material cylinder to an inlet during filling strokes. A means for monitoring operation of the pump is provided. The means for monitoring includes a means for sensing a first parameter related to operation of the pump drive, a means for sensing a second parameter indicative of operation of the piston, and a means for determining errors in the operation of the pump based upon the first parameter and the second parameter.
