Plum blossom coupling is a very commonly used coupling. Clean the parts before installing the plum blossom coupling. After cleaning the parts, dry the oil on them. Couplings that are ready for operation in a short time can be wiped dry and coated with turbine oil or engine oil to prevent rust. For couplings that need to be used for a long time, they should be painted with anti-rust oil for maintenance. Correctly install the main motor of the plum coupling and the equipment connected to the motor to correct the problem.
The correct way to align the coupling is to fix the equipment connected to the motor, add elastic plum blossoms, install the motor, and correct the coupling with a ruler. The motor should be cushioned. If the motor is high, first increase the equipment connected to the motor. Fix it, and align the motor. The correct installation of the coupling plays an important role in the service life of the elastic element. The plum blossom coupling is widely used in couplings. Therefore, the plum coupling must be installed correctly. Plum blossom coupling installation features are double or multi-section design, which can reduce vibration and noise, and is suitable for various pumps; maintenance-free, compact design, low inertia momentum; length can be selected; explosion-proof certificate in line with European standards. The plum blossom coupling is oil-resistant and electrically insulated.
The clockwise and counterclockwise rotation characteristics of the coupling are the same, and the middle of the coupling is connected by the elastic body; the coupling can absorb vibration and compensate for radial, angular and axial deviation; the precautions for hot-fitting the coupling is to apply it before heating Check whether the plum blossom coupling is paired with another coupling, especially if several units of the same unit are installed, find out the pair number or mark. There should be no defects such as burrs and scratches on the mating surface of the coupling. Always record the temperature rise and current value, and the temperature rise should not exceed 30°C per hour. After the temperature rises to 100°C, the inspectors should pay attention. When the sample rod is used to measure the aperture value, power outage operation. Fire fighting equipment should be provided in the heating area. After the coupling is hot-mounted on the shaft, cool the journal with cold water to prevent the heat from spreading to the armature and affecting the insulation.
