The invention discloses a mechanical sealing leakage detection system and method applied to long pipeline delivery oil pumps. The method includes acquiring leakage liquid quantity, when the detected the leaked liquid quantity meets the drop counting condition, acquiring a first flow signal of the leaked liquid quantity by the optical detection method; determining a first flow of the leaked liquid quantity according to the first flow signal; when the leaked liquid quantity cannot meet the drop counting condition, acquiring a second flow signal of the leaked liquid quantity by the optical detection method; determining a second flow of the leaked liquid quantity according to the second flow signal. Thus, mechanical sealing leakage can be detected online quantitatively, and the mechanical sealing leakage quantity can be detected accurately in real time.
