The invention discloses a large-megawatt-level draught fan performance testing tool and a testing method achieved through the tool. The tool comprises a first connecting flange provided with a first connecting stud, a second connecting flange provided with a second connecting stud and a rope. The first connecting flange is connected with a main transmission shaft of a large-megawatt-level draughtfan through the first connecting stud. The second connecting flange is connected with a main transmission shaft of a low-megawatt-level draught fan through a second connecting stud. The first connecting flange and the second connecting flange are oppositely arranged, and a plurality of lifting lugs are arranged on the opposite side faces of the first connecting flange and the second connecting flange. The first connecting flange and the second connecting flange are connected in the manner that the rope is wound around the lifting lugs, and the main transmission shaft of the large-megawatt-level draught fan, the first connecting flange, the second connecting flange and the main transmission shaft of the low-megawatt-level draught fan share the same rotation center line. By means of the large-megawatt-level draught fan performance testing tool and the testing method achieved through the tool, performance testing of the large-megawatt-level draught fan can be effectively finished.
Description
technical field [0001] The invention relates to the technical field of wind turbine performance testing, in particular to a performance testing tool for a large megawatt fan and a testing method realized by the tool. Background technique [0002] As is known in the industry, in order to understand, evaluate and analyze the performance of various parts of the fan, various tests are often carried out. The purpose of the test is to find various defects in the design, material and process of the fan. The reliability of the wind turbine is gradually increased, and finally reaches the predetermined reliability level. At the same time, it can also provide guarantees for improving the combat readiness of the generator set and reducing maintenance costs, so as to determine whether the wind turbine meets the specified reliability quantitative requirements, such as whether the power achieve goals and more. At present, wind turbines are developing in the direction of ultra-compact and ...
