Efficient axial-flow pump guide blade body

Abstract

The invention discloses an efficient axial-flow pump guide blade body. The efficient axial-flow pump guide blade body comprises a main shaft mounting part, an outer wall and guide blades; the diameterof the main shaft mounting part is gradually reduced in the axial direction; a first support rib plate and a second support rib plate positioned on the inner side are arranged at the end with largerdiameter; through main shaft center holes for mounting shaft pumps are formed in the support rib plates and the end with smaller diameter of the main shaft mounting part; the first support rib plate is provided with a fixed connecting screw hole; lower rubber bearings are arranged on the end surfaces of the second support rib plate and the first support rib plate; multiple guide blades are provided, and are uniformly arranged between the main shaft mounting part and the outer wall; and the guide blades are spiral arc surfaces. The efficient axial-flow pump guide blade body is mounted behind animpeller, effectively converts water current centrifugal kinetic energy to thrust to increase the water current conveying quantity, and meanwhile, achieves stable operation parallelism.

Description

technical field [0001] The present invention particularly relates to axial flow pump rotating impeller components. Background technique [0002] Axial flow pumps are large water conservancy equipment, mainly used for farmland irrigation and water conservancy transportation. The existing axial flow pump of water conservancy conveying equipment inevitably has processing errors and installation errors in the process of production, processing and installation. Long-term operation will cause the operation of the pump shaft and impeller equipment to be unbalanced, thereby accelerating the wear of the axial flow pump and reducing the water consumption. The delivery efficiency of the flow. Ordinary axial flow pumps use the centrifugal motion of the water flow carried by the impeller to generate horizontal pressure and then generate thrust. During this process, the water flow that leaves the impeller still has a large kinetic energy in the radial centrifugal direction, which is not ...

AI Technical Summary

Problems solved by technology

The existing axial flow pumps for water conservancy transportation equipment inevitably have machining errors and installation errors in the process of production, processing and installation. Long-term operation will cause the pump shaft and impeller equipment to run unbalanced, thereby accelerating the wear of the axial flow pump and reducing the water consumption. Flow Delivery Efficiency

Ordinary axial flow pumps use the impeller to carry the water flow centrifugally so that the water flow generates horizontal pressure and then generates thrust. During this process, the water flow detached from the impeller still has a large kinetic energy in the radial centrifugal direction and has not been converted into horizontal thrust, resulting in incomplete utilization of the delivery efficiency. At the same time, due to the high-speed rotation of the impeller, the operating condition of the impeller spindle is relatively harsh, and the problem of eccentricity and non-parallel is prone to occur, resulting in a decrease in the efficiency of the axial flow pump.
