Are the net positive suction head and effective net positive suction head on the pump sample the same concept? ?
Should the effective net positive suction head be: pump suction pressure - pipeline resistance - saturated vapor pressure? The pump suction pressure is generally greater than the pump’s effective net positive suction head, right? ? I hope the expert can give some guidance
Is the effective net positive suction head determined based on the net positive suction head specified in the pump manual? In other words, the effective net positive suction head must be greater than the net positive suction head specified for the pump model, and then the installation height of the pump is determined based on the suction pressure? ?
The pump technical data only provides the required net positive suction head; the effective net positive suction head is determined by the piping system. It is recommended that the original poster study the books on chemical engineering principles carefully
