What is the influence of the speed of the pump motor on the pump?
The question is very general,In general, high speed motors are used in 2 stages, 2900 revolutions per secondLow speed motor with 4 stage, 1450 revolutions per secondYou can probably generalize to thisWith the flow, head, run the pump speed type low noise will be reduced but the service life of the motor (relatively high speed), but the speed of price ratio low speed expensive (motor level 4 level 2 line than for more than copper)For example, it seems that the reason why turtles live longer is that their heart rate is slow.
Influence the parameters of pump flow and lift.
Low speed, the pump has a certain wear and tear
