This invention discloses a dual-piezoelectric tube driven inertial motor and its control method, along with a scanning probe microscope, relating to the field of piezoelectric tube technology. The invention includes a base, a first piezoelectric tube, a second piezoelectric tube, and a U-shaped sliding body. The first and second piezoelectric tubes are parallel to each other along their axes, with one end fixed to the base and the other end free. The two parallel arms of the U-shaped sliding body, referred to as the left and right sliding rods, are elastically connected via a junction at the bottom of the U-shaped sliding body. The left and right sliding rods are coaxially inserted into the inner walls of the first and second piezoelectric tubes, respectively. This invention not only ensures that the two sliding rods consistently and stably abut against the inner cavities of their respective piezoelectric tubes, guaranteeing effective transmission of driving force, but also improves the overall mechanism's motion accuracy, load-bearing capacity, and anti-interference capability through the coordinated and alternating operation of the dual-drive piezoelectric tubes, laying a structural foundation for achieving high-precision and high-stability stepping motion.

The utility model relates to pipeline mixer technical field especially relates to a pipeline mixer for reducing liquid nitrogen washing synthesis gas system resistance, including shell body, support ring, support rod, corrugated plate, flow guide hole and buffer assembly, the inner wall fixed setting of shell body has two groups of support rings, the inside fixed setting of support ring has a plurality of support rods, and a plurality of corrugated plates are arranged between two groups of support rings, and a plurality of flow guide holes are passed through and seted up in the inside of corrugated plate, and the inside of shell body is provided with buffer assembly, a pipeline mixer for reducing liquid nitrogen washing synthesis gas system resistance in the utility model is used in the process, and the inside support frame is with its firm frame structure, disperses the residual impact force, and the whole structure intensity of pipeline mixer is strengthened through the inside support structure of the device, and the impact force of super large gas synthesis gas is absorbed with buffer mechanism cooperation, effectively avoid the extrusion deformation of inner part under high load or emergency emptying condition, greatly reduce the risk of synthesis gas pipeline blockage.
