Background
At present, the water supply pump coupler of the domestic coal-fired unit mainly adopts a rigid coupler and a flexible coupler, and in a large-medium-sized unit, a membrane coupler is a common flexible coupler. The diaphragm coupler is a high-performance metal strong element flexible coupler, has a compact structure and high strength, and can compensate axial, radial and angular offset between a main motor and a driven motor caused by manufacturing errors, installation errors, bearing deformation, influence of temperature rise change and the like. The diaphragm coupler belongs to a flexible coupler of a metal elastic element, and the diaphragm coupler is connected with a main motor and a driven motor to transmit torque by virtue of a metal coupler diaphragm, has the advantages of elastic vibration reduction, no noise and no need of lubrication, has the characteristics of 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 supply pump runs at a high speed, the oil shield installation clearance is inconsistent or the bearing vibrates greatly, so that the shaft and the oil shield teeth are in collision and abrasion, the oil shield clearance is destructively increased, and the phenomenon that lubricating oil leaks into the coupler occurs. Meanwhile, the blowing effect generated by the high-speed rotation of the coupler can reduce the pressure in the housing close to the oil barrier and enlarge the oil leakage condition. If a large amount of oil leakage is not discharged in time, oil smoke can generate friction heat with a high-speed rotating shaft under the blasting effect, the temperature of a bearing and a coupling is increased, the gasification of oil is aggravated by the temperature rise, vicious circle is formed, the oil smoke density of a housing cavity is higher and higher, and after the oil smoke density reaches a certain limit, accumulated oil drops seep out along the joint of the housing, and the safe operation of a water supply pump is affected seriously.
