Why does the current decrease when the screw pump is switched back? ?
Thread Content
When the outlet flow rate of a centrifugal pump is increased, the current rises; then why does the current drop when a screw pump is operated in reverse? ?
Screw pumps belong to the category of positive displacement pumps. These pumps are characterized by the fact that their load depends on the smoothness of the pipeline: the smoother the pipeline, the lower the load. Therefore, before starting a screw pump, it is necessary to fully open the outlet valve to prevent a sudden increase in pressure that could damage the pump or the motor.
I wanted to confirm again; it should be related to the load. Thank you
Let’s confirm it’s correct – many hands make light work
Since I just started working in the chemical industry, there are many things I don’t understand; suddenly I realize I went to college for nothing
