What is NPSH? || Purpose Of NET POSITIVE SUCTION HEAD maintained in Centrifugal Pump || [हिंदी]

[@vinaykumarmishra3667]

I have try to understand the concept of npsh sice last 2 yr. As this question was asked to me in asian paint company and i was given therotical definition and he was not satisfied. Today first time my concept becomes clear. Thanx..

I read on a name plate of pump, it ia written than npsh = 0.25 meter. What is the meaning of it. I understand that in any pump suction pr at the eye of imperller shall be greater than its vapour pr. and lower than atm.pr. How 0.25 m ask us that it is lower than atm pr. But greater than vapour pr.

How to calculate shut-off pressure in centrifugal pump? In Which type of Suction NPSH is important?

[@PowerPlantDiscussion]

By closing discharge valve start the pump and gradually increase speed upto full, and watch the discharge pressure, that pressure is call shut off pressure

[@dineshmistry1107]

@@PowerPlantDiscussion How to calculate shut-off pressure by mathematically? Means If pump capacity is 20 M3/hr. what is maximum shut-off pressure?

[@PowerPlantDiscussion]

I still never study about mathematical calculation.

In which type of Suction NPSH is more important? Positive Suction or Negative Suction?

[@PowerPlantDiscussion]

Both conditions NPSH is necessary other wise Cavitation occur.
