The invention provides a precise adjusting device and method for blades of a draught fan of a cooling tower. The precise adjusting device comprises an installation base. The installation base is provided with a base counter bore. The base counter bore is internally provided with a gear. The center of the gear is connected with an adjusting locking rotary knob. A first locking threaded rod penetrates the adjusting locking rotary knob and locks the adjusting locking rotary knob, the two sides of the gear are provided with racks engaged with the gear, the two ends, back onto each other, of the two racks are each provided with a movable grabbing leg, the other side of the installation base is provided with two parallel extensible and retractable strips, the two parallel extensible and retractable strips and the racks are located on the same plane, the two parallel extensible and retractable strips are perpendicular to the racks, and the installation base is provided with a combined goniometer placement frame. By means of the precise adjusting device and method, the blades of the draught fan of the cooling tower can be adjusted to the precise angle needed by a user.
Description
Technical field: [0001] The invention relates to a device and method for accurately adjusting multiple blades of a cooling tower fan, and belongs to the technical field of mechanical equipment. Background technique: [0002] Iron and steel enterprises or other large enterprises use recycled water in the production system, and the recycled water has a certain temperature, which does not meet the reuse standard at all. The cooling tower fan is the equipment that reduces the temperature of the recirculated water to the standard that can be reused, and the angle of the original blade installation belongs to the initial state or theoretical standard. However, in the actual production system, there will be other reasons (such as the decline in the cooling function of auxiliary equipment) or objective reasons (such as continuous high temperature weather), so that the reuse of circulating water cannot be reduced to the reuse standard. In such cases, the angles of all the blades of ...
