Stainless steel fountain pump improper selection and operational errors

Stainless steel fountain pump improper selection and operation errors are likely to cause vibration. So, what are the potential causes of fountain pump vibration that is how to deal with it?
The following stainless steel fountain pump experts give some advice on the corresponding problem solution:
1, two pumps in parallel should ensure that the same pump performance. Pump performance curve should be slow down type as well, can not have hump.
2, the use of attention should be noted: to eliminate the factors that lead to fountain pump overload, such as the flow channel is blocked; appropriate to extend the pump start time, reduce the disturbance to the drive shaft, reduce the rotating parts and static parts between the collision and friction, and The resulting heat distortion; for water lubricated sliding bearings, start the process should be added pre-run water, to avoid dry start until the water pump and then stop the water.
3, the regular need to fill the oil bearing the appropriate amount of oil, for the long axis liquid centrifugal pump, because the shaft there is torsional vibration, if the use of a thrust tile, the damage is mainly thrust tile, then you can properly improve the oil Of the viscosity, to prevent the liquid dynamic pressure lubrication film damage.
4, fountain pump recommended In order to prevent the fountain pump amplitude is too large, you can also use the measurement and analysis of vibration to determine the best working parameters of the pump.
