Abstract
The utility model discloses a static balance testing device for a rotor of a bulb tubular turbine generator unit. The static balance testing device comprises a rotor to be tested. Balancing support beams for supporting the rotor to be tested are arranged under the same, and face the central axis of the rotor to be tested. Since the balancing support beams are arranged under the rotor to be tested, original point contact is changed into line contact, failure of the static balance test caused by overheavy rotor to be tested can be avoided, and stability and accuracy of the static balance test are improved. The static balance testing device can be used in the static balance test for the rotor of the bulb tubular turbine generator unit.
Description
Technical field
The utility model relates to a kind of rotor static balancing test unit of scaled bulb tubular hydraulic generator group.
Background technology
Rotor generally is made up of centrosome and magnetic pole two parts, and rotor center part is the thick coil plate welding back processing more than the 150mm by thickness then.Because the radian sum of errors welding deformation of thick coil plate so the rotor circumference yoke thickness difference after the processing is bigger, causes the static equilibrium difference of rotor center bigger.If do not eliminate this rotor static balancing error; Unit will produce very big unbalance dynamic in operational process; Serious vibration aggravation when making unit operation; Even can't run well, so need carry out the static equilibrium adjustment to rotor, the static equilibrium adjustment of rotor is exactly to make the X line of rotor and the balance duty that the Y line is in a standard.
Existing uneven test instrument is made up of poising tool and base.Poising tool is by the piston cylinder that is fixed in rotor and macro-axis connecting flange face, and passes the piston that piston cylinder goes up and down as scalable with screw rod and form, and in piston cylinder, inlays an alloy hemisphere.Balanced support rib 7 bases then are made up of the alloy platform on base and the inlaying base.
During static balancing test, poising tool is put together on the center of rotor center part, the centre of sphere adjusting of can on the rotor axis line, moving; After support member was left at the two ends of rotor, the alloy hemisphere of poising tool formed the some contact with the alloy platform, because the weight of rotor is heavier; Be about 100 tons; Can make the contact of the hemispherical point of balanced support rib 7 alloys contact becoming face, thereby reduce the accuracy of test, be out of shape and to cause 7 plastic yield of balanced support rib when serious and can't use.After the off-test, rotor is sling could the dismounting poising tool.
