Relationship between diameter and power, lift and flow of pump impeller
The relationship is not very clear, but every turn left wing leaves are water head and flow, thus will affect the impeller diameter, leaf number, fin height and curve are influential, not that a direct impact on the impeller
The head is related to the diameter of the impeller. The larger the impeller, the greater the lift, and vice versa. The flow rate has little to do with the impeller diameter. Under the rated conditions, the greater the head, the smaller the flow rate, inversely proportional.
The relationship between the centrifugal pump water delivery and the vacuum degree is that the centrifugal pump is the centrifugal force principle to complete pumping. Without water, the time and space turn will burn out the equipment.
The larger the diameter of the impeller, the greater the lift, the greater the flow rate, because the flow rate of water depends on the centrifugal force generated by the impeller rotation and the line speed on the tangent. The greater the diameter, the greater the centrifugal force and the linear speed
