Abstract
The utility model provides a jack-up is with wire-wound motor carbon dust adsorption equipment, belongs to motor technical field to solve current jack-up and reuse wire-wound motor collecting ring and brush holder device rotation contact circular telegram, the carbon dust that produces scatters in the motor cavity, hinders the motor heat dissipation, leads to insulating inefficacy to make the motor turn to turn, leads to double-phase short circuit, and local current increases, burns out the problem of collecting ring and brush holder device. The utility model discloses a rotor dust board, stator dust board, rotor, stator, annular casing and adsorbed layer are fixed with annular casing and stator dust board on the rotor, are equipped with the adsorbed layer in the annular casing, and the surface of annular casing is equipped with a plurality of absorption holes, and the annular casing is located between rotor dust board and the collecting ring, is fixed with the stator dust board on the stator, all processes the fitting surface that is the rectangular wave on stator dust board and the rotor dust board, and two fitting surfaces are laminated together each other. The utility model is suitable for a wire winding motor is used in the jack-up.
Description
Technical Field
The utility model relates to a motor carbon dust adsorption equipment, concretely relates to winding motor carbon dust adsorption equipment for jack-up.
Background
At present, a YZR series hoisting and metallurgy wound rotor motor, as shown in figure 1, a rotor is electrified through rotating contact of a collecting ring 5 and a brush holder device 4, carbon blocks 3 on the brush holder device 4 rub with the collecting ring 5 to generate carbon powder inevitably, the carbon powder flies and falls into a cavity, part of the carbon powder enters the cavity of the motor through a gap of 2mm between a stator dust guard plate 2 and a rotor dust guard plate 1 and then is attached to the surface of a stator and rotor winding to block heat dissipation of the motor, insulation failure is caused to cause inter-turn of the motor, and part of the carbon powder is attached to insulators between the collecting ring 5 and a phase to cause two-phase short circuit, local current is increased, and the collecting ring 5 and the brush holder device 4 are burnt.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, and provide a winding motor carbon dust adsorption equipment for jack-up.
The utility model discloses a solve the technical scheme that above-mentioned technical problem took and be:
the utility model provides a winding motor carbon dust adsorption equipment for jack-up includes the rotor dust board, the stator dust board, the rotor, the stator, annular housing and adsorbed layer, be fixed with annular housing and stator dust board on the rotor, be equipped with the adsorbed layer in the annular housing, the surface of annular housing is equipped with a plurality of absorption holes, the annular housing is located between rotor dust board and the collecting ring, be fixed with the stator dust board on the stator, all process on stator dust board and the rotor dust board and have the fitting surface that is the rectangular wave, two fitting surfaces are laminated together each other.
Compared with the prior art, the utility model following beneficial effect has:
the utility model discloses stator dust board and rotor dust board pass through the ring channel cooperation, adopt labyrinth's seal structure, avoid the carbon dust to get into motor cavity inside and cause insulation failure to make the motor turn-to-turn and hinder the radiating problem of motor. Simultaneously, set up annular housing, and the inside adsorbed layer that sets up of annular housing makes the carbon dust through directly adsorbing through the adsorbed layer, avoids burning out collecting ring and crouching the problem of brushing the device.
