| description | The invention discloses a calculation method for deducing real-time concentration of a suction port from vacuum of a dredge pump. The calculation method comprises the following steps: S1, listing an expression of a total water head H; s2, listing a head loss expression; s3, listing a water head expression at the inlet of the mud pump; s4, establishing a relational expression between water heads; s5, obtaining an equation of the vacuum of the dredge pump and the average concentration of the suction section by combining the vacuum of the dredge pump; s6, calculating the real-time average concentration Cavg of the suction section; and S7, calculating the real-time concentration Cin at the suction port in combination with the real-time slurry concentration at the mud pump. The method is pioneered and has the advantages of being high in calculation speed and free of delay. Moreover, the method only needs a small amount of historical data to correct part of parameters of the model, the working condition exceeding t |
