Biological pump with automatic calibration function

The utility model discloses a biological pump with an automatic calibration function, which is characterized in that a flow corrector is added on the basis of an original biological pump, an inlet part of the flow corrector is connected with an outlet part of a pressure transmitter through a first connecting pipeline, and the flow corrector and the pressure transmitter are fixedly arranged on a calibration platform base. The flow corrector comprises an FT flow meter and a PCV automatic pressure regulating valve, and the FT flow meter and the PCV automatic pressure regulating valve are connected through a second connecting pipeline and then are electrically connected with the biological pump controller. According to the scheme, the flow corrector can be used for rapidly and accurately calibrating the flow in a full-automatic mode according to requirements, continuous and stable accurate flow can be provided for use of the biological pump, the labor cost is effectively reduced, the corresponding production peri
