摘要：a system to pump particularly suitable for pumping and wet sludge

mixtures.provides a pulse pumped out of material substantially without movement orchanges in order to pistons (12a, 12b) in a power cylinder power (10a, 10b).the powerpiston (12a, 12b) are connected by connecting rods of the pistons (14a, 14b) of thepumping pistons (16a, 16b), which are the material pump through valves (20a)20 (b) andpushed through valves (22a, 22b) in a discharge line (16).a closed loop (32) connects theannular chambers (13a, 13b) of the power cylinder (10a, 10b), and a pump (p2) whichcontinuously feeds the closed loop (32).the power piston (12a, 12b) are moving faster intheir race for the suction discharge stroke, so that one or the other or both pistons (12a.(b) are always moving forward.a proper control for a smooth flow of material beingpumped is provided by detection valve (pva1, pva2, pvb1, pvb2) on each power cylinder(10a, 10b).these valves are designed to be operated in different positions of the powerpiston (12a, 12b) in the cylinder.the detection signal to the valves check valves (cv1)cv2) toclose the vent, and a closed loop (32) in response to the actuation of the valves andmovement detection and control of power pistons in the cylinders.
