Using of self priming pump

1. This series self-priming pump, according to the work of the pump operating conditions, respectively, using high-quality calcium butter and No.10 oil lubrication, if the lubricating grease pump should be regularly to the bearing box to add the butter, the lubricating oil pump, if the oil is not enough, plus foot.

2. Check the pump shell storage solution is higher than the impeller on the edge, if can from the mouth of the pump shell liquid directly into the pump body into the liquid storage, should not start running in Chu liquid insufficient, otherwise the pump can not work normally, and easy to damage the mechanical seal.

3. Moving parts, check the pump is stuck knocking phenomenon.

4. Check the pump body and the connecting nut at the foot loose phenomenon.

5. Check the pump shaft and the motor shaft of the coaxial degree of peace.

6. check the import pipeline is leaking, if there is a leak, must try to exclude.

7, open the suction line of the valve, a little open (not fully open) export control valve.

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. The pump into the normal operation of the pumping money that is self priming 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 pump fluid hyperthermia caused by self suction difficult, you can temporarily shut down, the spit liquid pipe flow back to pump or to the mouth of the pump body and Chu liquid directly to the pump of liquid, the temperature of the liquid in the pump decreased, and then start can be.

6. The 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. Velocity is too large can adjust export control valve, heating pressure gauge readings, the import pipeline blockage should be ruled out in a timely manner; suction is too high may be appropriate to reduce the pump mounting height.

7. The pump in the working process for some reason, stop the pump and need to restart, export control valve slightly open, not closed), this is conducive to the self absorption process in gas discharged from the outlet and to ensure the pump under lighter load start.

8. Pay attention to check the pipeline system, there is no leakage phenomenon.

1. Must first shut off the valve on the pipeline.

2. To stop the pump rotation.

3. The freezing season should be cooling the indoor water reservoir and the bearing in the pump off, to prevent the cracking parts.
