Pay attention to whether the steering of the pump axis is correct when starting the self -suction pump. Note whether there are abnormal sounds and vibrations when rotating. Pay attention to the reading of the pressure gauge and the vacuum table. After the start of the pressure gauge and the vacuum table after starting, the number of readings instructed by stable after a period of fluctuations, indicating that the self -suction pump has already been liquid and enters the normal infusion operation.

      Before the self -suction pump enters the normal infusion operation, in the process of self -suction, special attention should be paid to the height of the water temperature in the pump. If the process is too long and the water temperature in the pump is too high, the pump is stopped to check the cause. If the temperature of the liquid in the self -suction pump is too high and causes self -suction difficulties, then you can temporarily stop. Use the liquid inversion in the pipe to return to the pump or add the storage liquid to the pump directly to the pump to add the liquid The inner liquid cools down, and then start.

      If a strong vibration and noise occur during the working process, it may be caused by steam erosion in the pump. There are two reasons for the occurrence of steam erosion: one is that the import pipe flow rate is too large, and the other is that the suction process is too high. When the flow velocity is too large, the export control valve can be adjusted, and the reading of the pressure gauge is increased. When the imported pipeline is blocked, it should be eliminated in time; when the inhalation process is too high, the installation height of the pump can be appropriately reduced.

  The self -suction pump stops the pump due to the reason during the working process. When the export control valve needs to be started again (not completely closed), this will not only help the gas from the vomiting exit during the self -absorbing process, but also ensure that the tip is lighter to lighter. Start under responsibility. Pay attention to check the pipeline system for leakage.
