| Zusammenfassung: | The utility model relates to a high-concentration coal water slurry long-distance pipeline multi-line combination pump conveying device which overcomes the defects in the prior art. A multi-line parallel mode is adopted to pave conveying pipelines. The conveying device comprises inlet pipelines, inlet valves, power pumps, outlet pipelines and outlet valves. The inlet pipelines are formed by two pipelines, and the outlet pipelines are formed by two pipelines. The number of the power pumps is three. When the two pipelines of the inlet pipes and the two pipelines of the outlet pipelines are separately started in sequence, the pipelines enable two power pumps which do not work to be combined. The high-concentration coal water slurry only needs the three power pump bodies rather than original four power pump bodies, and the investment of the power pump is reduced by one-fourth. |
