1.Point moving ZX self suction pump, pay attention to the pump shaft is correct.
2.Pay attention to rotation when there is no abnormal sound and vibration.
3.Pay attention to the pressure gauge and vacuum gauge readings, starting after the pressure gauge and vacuum gauge readings after a period of time and the stability of the fluctuations, indicating that the pump has been on the liquid into the normal infusion operation.
4.Before the pump into the normal operation of the infusion, that is, during the suction process, we should pay special attention to the water temperature rise, if the process is too long, the water temperature is too high, then stop the pump to check its cause.
5.If the temperature of the liquid in the pump suction is too high and cause difficulties, you can temporarily shut down, according to the discharge liquid in pipeline flow back to the pump body or pump with liquid outlet directly to the pump fluid, cooling the liquid in the pump, and then start to.
6.Pump in the work process, such as strong vibration and noise, there may be caused by the pump cavitation, cavitation, there are two reasons: first, the inlet pipe flow rate is too large, two is too high suction process. The velocity is too large when the adjustable outlet control valve, pressure meter, in the import pipeline blockage should be eliminated in time; when the suction is too high may be appropriate to reduce the pump mounting height.
7.Pump in the work process for stopping the pump, to restart, export control valve should be slightly open (not closed), this is conducive to the gas suction process from the discharge outlet, and can ensure the tip is in charge of the lighter start.
8.Pay attention to check the pipeline system, there is no leakage phenomenon.
