Description
Technical field
The utility model relates to static balance testing device, particularly a kind of large-scale fan static balance testing device.
Background technology
At present large-scale fan static equilibrium instrument is being detected in the makeover process, adopting the method for static equilibrium instrument support range estimation counterweight mostly.Measure inaccurately, efficient is low, detects and revises and can not once finish, and need carry out transient equilibrium, complicated operation, cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of measurement accurate, and the efficient height detects and revises and can once finish, and does not need to carry out dynamically balanced steel-ball type fan static equilibrium instrument.
In order to achieve the above object, the technical solution adopted in the utility model is:
Steel-ball type fan static equilibrium instrument, it comprises base, on described base top surface, load sensor is installed, the central through hole that the axis that the horizontal component support of the carrying cover of a ⊥ shape is arranged on the described load sensor and its vertical centre partly has its axis and base is coaxially set, the bottom surface that its crown center has the mandrel of taper hole is connected on the end face of base and mandrel top is inserted in bottom in the central through hole, in described central through hole, be inserted with its top the adjusting screw(rod) of handle is installed, the top of described adjusting screw(rod) is threaded with central through hole and the middle lower cone hole that has in its bottom, steel ball be contained in described on, between the lower cone hole, the upper and lower of described steel ball is respectively with last, the setting that matches of the surface of contact of lower cone hole, outer wall interference fit at described carrying cover is equipped with key, and the signal output part of described load sensor links to each other by data line with intelligent display controller signal input part.
Advantage of the present utility model is: adopts this apparatus structure simple, measures accurately, detect with correction and once finish, and simple to operate, the efficient height, cost is low, and is easy to maintenance, easily forms tandem product.
Description of drawings
Accompanying drawing is the diagrammatic cross-section of steel-ball type fan static equilibrium instrument of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
Steel-ball type fan static equilibrium instrument of the present utility model as shown in drawings, it comprises base 2, on described base 2 end faces, load sensor 3 is installed, the central through hole that the axis that the horizontal component support of the carrying cover 6 of a ⊥ shape is arranged on the described load sensor 3 and its vertical centre partly has its axis and base is coaxially set, the bottom surface that its crown center has the mandrel 4 of taper hole is connected on the end face of base 2 and mandrel top is inserted in bottom in the central through hole, in described central through hole, be inserted with its top the adjusting screw(rod) 7 of handle 8 is installed, the top of described adjusting screw(rod) 7 is threaded with central through hole and the middle lower cone hole that has in its bottom, steel ball 5 be contained in described on, between the lower cone hole, the upper and lower of described steel ball is respectively with last, the setting that matches of the surface of contact of lower cone hole, outer wall at described carrying cover is equipped with key by interference fit, is used to adjust position of fan.The signal output part of described load sensor links to each other by data line with the signal input part of intelligent display controller 10.As shown in the figure supply socket 12 can be set on base, be used for external power supply, the spool 11 that is connected between base and the intelligent display controller 10 is used to pass data line.Base can be installed on the ground foundation 1.Described load sensor 3 can adopt the cantilevered load sensor.
The using method of the utility model device is as follows:
The effect of adjusting screw(rod) 7 is the weight that contacts that can finely tune when placing tested fan with load sensor, by handle 8 manual up-down adjustment.
Be unkitted before the tested fan, this device has carried out trim work.Tested fan is installed on the ⊥ shape load-bearing cover 6, tested fan will be to laying particular stress on direction, the load sensor 3 that level is installed will detect data and directly be presented on the intelligent display controller 10, by the amount of laying particular stress on tested fan correspondence position loss of weight only be met in the static equilibrium accuracy requirement scope to reaching tested fan.It is qualified all to be in static equilibrium accuracy requirement scope at the mean value of some locational amounts of laying particular stress on by the tested fan of key 9 hand rotation.
The output terminal of described cantilevered load sensor 3 outputs signal to the signal input part of intelligent controller, is used for showing and prints little static equilibrium accuracy detection and correction data of laying particular stress on.
This device can detect the static equilibrium precision of diameter smaller or equal to the large-scale fan blade combination of 2M.The little measuring principle that lays particular stress on of steel ball that the employing level is installed, tested fan once is installed can finish detection, revise a plurality of operations.Static-unbalance can directly show and print, and detects and revises the efficient height, and is simple to operate, easy to maintenance, can form tandem product.
