Embodiment Construction

[0021] Combine below figure 1 The concrete implementation method of the present invention is described:

[0022] A moment load measurement balance calibration system for the rotating shaft of a wind power generating set such as figure 1 As shown, it includes a calibration loading mechanism, a data collector, a hydraulic servo system, and a loading control system.

[0023] Calibrate the loading mechanism as figure 1 shown. The calibration equipment is composed of a square upper bracket 2 and a lower bracket 3, each bracket is about 6 meters long and 6 meters wide, and adopts a reinforced plate welded structure. It has good manufacturability and high strength. The thickness of the bottom plate is 80mm, and the material is 20MnMo. The thickness of the vertical plate is 60mm, the height of the vertical plate is 280mm, the interval between the vertical plates is 500mm×500mm, the top of the vertical plate is strengthened by welding the rib plate, and the material is Q370R. A f...

Abstract

The invention discloses a calibration system for a fan electric generator set rotation shaft torque balance. The calibration system for the fan electric generator set rotation shaft torque balance comprises a loading unit, a data acquisition unit and a control unit, the loading unit comprises loading tools and a loading mechanism, the loading tools comprise a base and a square plate used for applying a twisting torque, the lower end of the torque balance requiring to be calibrated is fixed to the base through screws, the upper end of the torque balance is fixed to the square plate through screws, the base and the square plate are both horizontally arranged, the loading mechanism is respectively connected with the square plate and the base in a ball-hinged mode, a torque Mx around an X-axis, a torque My around a Y-axis and a torque Mz around a Z-axis are applied on the torque balance through the square plate, the loading mechanism is in signal connection with the control unit through aforce transducer, and the data acquisition unit is in signal connection with the torque balance. According to the calibration system for the fan electric generator set rotation shaft torque balance, three torque values with large loads can be applied at the same time, so that accurate calibration of the torque balance is achieved.

Description

technical field [0001] The invention relates to the field of torque measurement of a rotating shaft of a fan generator set, and relates to a calibration system for calibrating a measuring balance of the rotating shaft torque and ensuring the accuracy of the measuring data of the rotating shaft torque. Background technique [0002] As an important part of clean / renewable energy, wind turbines have attracted more and more attention from governments, and their installed capacity continues to rise. According to the data released by the National Energy Administration, as of July 2017, the total installed capacity of wind power in my country reached 154 million kilowatts. The installation location of wind power equipment has also gradually shifted from the northwest to the southeast coastal power consumption area. The installed capacity of offshore wind power equipment has reached the third place in the world. With the development of the economy, the wind power equipment in the so...
