3 hp vertical centrifugal pump with 8.3m3/h maximum flow, 33m maximum head and 40mm diameter of inlet and outlet.Features:
Vertical centrifugal pump dimension (unit: mm):
Tips: Analysis of the low operating efficiency of the centrifugal pumpThe loss of liquid flowing through the impeller includes mechanical losses, flow losses, and leakage losses, and the corresponding efficiency of the centrifugal pump is divided into mechanical efficiency, hydraulic efficiency, and volumetric efficiency. The mechanical loss includes wheel dropping losses consumed because of the friction between the impeller wheel cap, outer side and the liquid, the friction losses between the bearing and stuffing box and the leakage losses. The leakage losses include the leakage losses at the impeller sealing ring site and interstage and axial force balance mechanism. Most of its losses are converted into heat, which shall be absorbed by the fluid afterwards.Low pipeline efficiency: When the conveyed liquid has changes in flow rate or head, the most common treatment means is to regulate the valve. Although this method is convenient, it still has many disadvantages because it will bring great losses to the pipeline resistance, thus enabling the centrifugal pump to operate under the low-efficiency status.
