In-phase peristaltic pump
ActiveCN224120357USimple structureSimplify pipingPositive displacement pump componentsFlexible member pumpsPeristaltic pumpPump head
The embodiment of the utility model discloses an in-phase peristaltic pump which is characterized in that a stop valve is arranged on the basis of an existing peristaltic pump, the stop valve is arranged outside a pump head, the stop valve is matched with the position of a roller in the pump head, and the stop valve is started at proper time, so that liquid is blocked in the pump head adjusting process; and the initial phases of the pump head are completely the same when the liquid is quantitatively output every time. In the liquid filling process, the release action that the hose is pressed by the rolling wheel is avoided, the influence of pulsation on quantitative transmission precision is eliminated, and the filling precision is improved. According to the scheme, the original advantages of cleanliness, easy maintenance, good controllability and the like of the peristaltic pump are reserved, meanwhile, accurate quantitative transmission of the peristaltic pump is achieved, the filling efficiency of the peristaltic pump is improved while the filling precision is improved, and the advantages of being low in cost and wide in adaptability are achieved.

Cantilever beam type phononic crystal and parameter optimization method
ActiveCN116129846Bachieve barrierEasy to adjustSound producing devicesCantilevered beamVibration control
The present application belongs to the technical field of ship vibration control structure or method, and particularly relates to a cantilever beam type phononic crystal for vibration isolation and a parameter optimization method. The phononic crystal comprises a power-law prism base, a cross-shaped cantilever beam and a mass block. The power-law prism base comprises a power-law prism part and a base part. The cross-shaped cantilever beam is a cross-shaped flat plate structure, and the mass block is located at the end of the cross-shaped cantilever beam. The cantilever beam type phononic crystal based on the present application can be used for vibration control of different materials and different thicknesses. In actual application, only the material parameters and thickness of the flat plate need to be substituted, and the other part sizes and materials of the cantilever beam type phononic crystal are designed according to the flat plate size and vibration source frequency, so that the band gap frequency range covers the load frequency, and the vibration of the target frequency can be blocked. The structure of the cantilever beam type phononic crystal based on the present application can use materials with different elastic moduli to prepare the cross-shaped cantilever beam and materials with different densities to prepare the mass block, so that the band gap frequency range can be adjusted conveniently and quickly.
