Zusammenfassung: | The invention discloses an automatic control starting method for a long-distance large-pipe-diameter water conveying and transferring pump station pump set. Due to the fact that a water lifting pipeline is in a full water state before pump starting, in the pump starting process, in order to eliminate a pump starting water hammer of the pump set and prevent water in the water lifting pipeline fromflowing back to a pump station, the opening time of a hydraulic control valve must be accurately controlled, and therefore the pressure of a valve on the outlet side of a water pump must be larger than the pressure behind the valve, that is, when the pressure of an outlet of the water pump is larger than the working pressure of the pipeline, the hydraulic control valve is opened, the water in thewater lifting pipeline cannot flow back to the pump station, and the situation that the pump set rotates reversely, and equipment in the station is damaged is prevented. By means of the above technical scheme, the technical pr |
