Avoid fountain pump selection improper and operation mistakes

Improper fountain pump selection and operation error is likely to cause vibration. So, these potential causes fountain pump vibration is how to handle?

The fountain pump experts to give some advice on problem solving methods accordingly:

1, two parallel should guarantee the pump performance is the same. Pump performance curve type should slow down for good, can not have a hump.

2, pay attention to when using: eliminate cause fountain pump overload factor, such as port congestion; The time to extend pump and reduce the disturbance of the shaft, reduce the collision and friction between rotating parts and stationary parts, and the resulting thermal deformation; For lubrication of the sliding bearing, water should be added in the process of start prelubricated water, avoid dry, until the water pump water stop again after water injection.

3, to need to bearing a moderate amount of oil injection oil on a regular basis, for long axis under liquid centrifugal pump, because the shafting torsional vibration, if use have thrust tile, is damaged main thrust tile, then can improve the lubricating oil viscosity, appropriate to prevent the destruction of the liquid dynamic pressure lubrication film.

4 the amplitude of the fountain, fountain pump Suggestions to prevent the pump is too large, you can also use the vibration measurement analysis condition to determine the best working parameters of the pump.
