net positive suction head การใช้

• Two pumps in succession are used to provide sufficient net positive suction head to prevent cavitation and the subsequent damage associated with it.
• Note that it is equivalent to the sum of both the static and dynamic heads  that is, the stagnation head  from which one deducts the head corresponding to the equilibrium vapor pressure, hence " net positive suction head ".
• Centrifugal pumps and compressors are defined by the Hydraulic Institute as  a kinetic machine converting mechanical energy into hydraulic energy through centrifugal activity .  Sundyne Pumps also utilize state-of-the-art inducers for low NPSH ( Net Positive Suction Head ) situations.
