Description
Technical Field
The invention relates to the technical field of steam turbine devices of coal-fired power plants, in particular to a film type coupling housing with a cooling anti-shaking effect.
Background
At present, the water supply pump coupling of the domestic coal-fired unit mainly adopts two types, namely a rigid coupling and a flexible coupling, and in a large-medium unit, a membrane type coupling is a common flexible coupling. The diaphragm coupling is a high-performance metal strong element flexible coupling, has a compact structure and high strength, and can compensate axial, radial and angular offsets between a driving machine and a driven machine caused by manufacturing errors, installation errors, bearing deformation, temperature rise change and the like. The diaphragm coupling belongs to a metal elastic element flexible coupling, and the metal coupling is used for connecting a driving motor and a driven motor to transmit torque by depending on a metal coupling diaphragm, so that the flexible coupling has the advantages of elastic vibration reduction, no noise, no need of lubrication, acid resistance, alkali resistance and corrosion resistance, and is suitable for shafting transmission in high-temperature, high-speed and corrosive medium working condition environments.
When the water feed pump runs at a high speed, the mounting clearance of the oil shield is inconsistent or the vibration of the bearing is large, so that the shaft and the oil shield teeth are abraded, the clearance of the oil shield is increased destructively, and the leakage phenomenon of lubricating oil towards the coupler occurs. Meanwhile, the blast effect generated by the high-speed rotation of the coupler can reduce the pressure in the housing close to the oil stop, and the oil leakage condition is enlarged. If a large amount of oil leakage is discharged in time, oil smoke can generate friction heat with a high-speed rotating shaft under the blast effect, the temperature of a bearing and a coupler is increased, the oil smoke is gasified by the increase of the temperature to form vicious circle, the oil smoke density in a housing cavity is higher and higher, after a certain limit, the oil smoke is accumulated into oil drops, the oil leakage is carried out along the joint of the housing, and the safe operation of a water feeding pump is seriously influenced.
