Urgent, there is a problem with the canned pump! ! !
Thread Content
There are two canned pumps of the same model in the company with the same medium, but one of them always looks bad. There is no blockage or foreign matter in the inlet and outlet pipelines. The inlet filter is very clean. I disassembled the pump and checked and found no problems. What is the reason? Can anyone give me an answer? Thank you.
Is stress normal? Does the pump body get hot?
Are there any problems with the G value and string quantity? Check, is it reversed? ? ?
Is the pump reversed? If there is no reversal, can the positions of the two pumps be reversed? (Without affecting production). If it is confirmed that there is no problem with the pipeline and the pump does not reverse, there is something wrong with most canned pumps.
Check whether the impeller front ring gap is large and whether the shaft deflection is appropriate.
Check whether the impeller front ring gap is large and whether the shaft deflection is appropriate.
Be more detailed: If what the poster said is correct, then check from the following aspects: 1: Measure whether the gap in the front ring of the impeller exceeds the standard. Depending on the size of the impeller, the gap is also different, generally between 0.4--0.7mm · 2: Whether the rotor deflection is large or small. General total channeling: 3--5mm。 3: Is the clearance of the graphite bearing appropriate? 4: Is the rotor bent?
If there is no problem with the piping system and your process medium, there should be a problem with your assembly.
It's usually an intermittent problem, check it carefully.
