Abstract
The invention relates to an axial-flow pump impeller used for chemical reactor. The outer diameters of the impeller and wheel hub are 900mm and 545mm, the excircle of the wheel hub is provided with five blades, the five radial sections of the blade are respectively located at the positions 0.545mm, 0.632mm, 0.721mm, 0.809mm and 900mm on the blade; five radial section mounting angles are 28.46 degrees, 22.22 degrees, 17.86 degrees, 14.74 degrees and 12.39 degrees; the chord lengths of the five radial sections are 0.227mm, 0.304mm, 0.326mm, 0.342mm and 0.353mm; and X and Y numerical values of coordinates of blade plane of the five radial sections are given. By adopting the impeller composed of five blade accurate blade shapes, the impeller can operate at high temperature, and axial-flow pump matched with the impeller also accurately achieves the numerical values of the designated flow and lift. Process requirement of chemical reactor in actual operation can be completely met, and the axial-flow pump impeller completely satisfies the requirement. The invention has high efficiency and high reliability and can save energy.
Description
technical field [0001] The invention belongs to an axial flow pump, in particular to an axial flow pump impeller for a chemical reactor. Background technique [0002] At present, with the rapid development of chemical production technology, the requirements for chemical reactors are becoming more and more large-scale and large-flow. Therefore, the performance requirements for axial flow pumps for chemical reactors at home and abroad are also increasing. To be precise, it is required that the accuracy of the flow rate and head of the axial flow pump matched with it should also be greatly improved. However, there is no strict working temperature of 450°C and a flow rate of Q=5760m in a specific chemical reactor. 3 Axial flow pump impeller under the conditions of / h, head H=4.5m, speed n=420r / min. Contents of the invention [0003] In order to solve the technical problems existing in the known technology, the present invention provides a strict working temperature of 450°C ...
