Lift of metering pump
Thread Content
The parameters that can be found for a diaphragm metering pump are: Number of strokes 94 times/min Maximum working pressure: 0.3MPa Maximum suction lift 3m Nominal flow rate 353L/H So can you tell the size of its lift from these numbers? It seems to be the maximum working pressure and maximum suction lift. So which one is it? But I think it is neither. Now that the liquid is added to the pressure pipe, the pressure may not be enough. But I don’t know its lift. This post was last edited by Hailanghua on 2008-2-22 16:13 ]
Lift is the maximum working pressure. The suction lift is considered from the perspective of inlet pressure. Equivalent to the effective cavitation margin of a centrifugal pump. For metering pumps, the inlet pressure has no effect on the outlet pressure. As long as the pressure of the pressure pipe is less than the maximum working pressure, normal operation can be guaranteed.
Upstairs, are you sure your answer is correct? Regarding "the head is the maximum working pressure". Do you think this sentence is interpreted correctly???
