Pump impeller diameter plus assembly what changes? What's the effect on the motor?
1., the larger the diameter of the impeller, the greater the head, the greater the flow rate, because the flow of water depends on the speed of rotation of the impeller generated by the centrifugal force and the line speed on the tangent, the greater the diameter, the centrifugal force and the greater the speed of the line. 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.2., the head and impeller diameter is related, the larger the impeller, the greater the head, 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.
Two 1.5 kW desktop self-priming pump impeller 14.7cm primary current 15.5cm problems may occur.After the impeller increases, the flow, head, shaft power will increase (increase in volume see the following formula), the original 1.5KW motor may overload operation.
Two item 1.5 kilowatt type self suction pump original impeller 14.7cm installed 15.5cm may be a problem.After the impeller increases, the flow, head, shaft power will increase (increase in volume see the following formula), the original 1.5KW motor may overload operation.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. 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. Vacuum pumping or vacuum pumping two times.The vacuum of the inlet of the centrifugal pump is composed of three parts (the equation of the inlet of the pump and the level of the suction liquid).
