In-phase peristaltic pump

By designing a combination of pump head and shut-off valve in the peristaltic pump, the structure is simplified and the pressure inside the hose is controlled, achieving high-precision quantitative filling. This solves the problem of complex structure in existing in-phase peristaltic pumps and improves filling accuracy and efficiency.

AI Technical Summary

Technical Problem

Existing in-phase peristaltic pumps have complex structures, cumbersome operations, and complex pipelines, making it difficult to achieve high-precision quantitative filling.

Method used

The pump head and shut-off valve are combined in a design. The pump head has an inflatable arc of less than 360 degrees per roller. The shut-off valve is located at the liquid outlet of the hose. The pressure inside the hose is less than the sealing value of the shut-off valve. Combined with the operation of the roller assembly, the liquid is delivered in a metered manner.

Benefits of technology

The pump head structure and pipeline have been simplified, improving filling accuracy and reliability. The release action of the roller pressing the hose has been avoided, thus improving the accuracy and efficiency of quantitative transmission.

Abstract

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.
